Best use of a model in cairngorm

I'm a bit confused about the use of a model, ModelLocator in cairngorm

I created it and everything works fine but what is the best way to access it, currently I have many forms that all do something like

< fx:Script >
<! [CDATA]

import com.model.ModelLocator;

[Bindable] private var model: ModelLocator = ModelLocator.getInstance ();

and then later on

private void fun1(evt:Event):void
{

Model.something = 'blah '.

var s1:String = model.anotherSomething;

}

or something else

Is it OK to have varibles across the mxml files different all creating a model private var, made this last resouces or is it ok because than its static

I have also several arrayCollections 11 + other stuff in the model, is this ok

Hi JockMahon,

Its ok fine, you can go with this...

However do not forget something you will be declaring variables in the ModelLocator class if you use them in your application. I mean more of an mxml page, or in the form of files. However if you need to a property or variable in a single file, then you can declare it locally in the file instead of inside decalring

ModelLocator.

ModelLocator in cairngorm framework is a class singleton in how many files, you have a model variable, it will actually return or return only single instance of the ModelLocator class static.

[Bindable] private var model: ModelLocator = ModelLocator.getInstance ();

How many times, you have a variable using the style above decalring then you will get only a single static reference to the instance of the ModelLocator class. No no instances are created. It's like you get a pointer to the model variable.

I hope it is clear now.

Thank you

    How can I make the best use of a new external hard drive and a new catalog full of photos just loaded into Photoshop elements 14 Organizer?

    Keep all the files on external hard drive image?  Nothing else and no pictures on the desktop?

    Keep all image files both places?

    What is the best way to go through thousands of images in the Organizer to identify and place them in files?

    Once I've placed a file, I just leave it in the entire catalog or a way indicate to me that it has been sorted?

    As I only have the version of the EP, here is some info on the organiser:

    https://helpx.Adobe.com/Photoshop-elements/how-to/use-elements-Organizer.html

    Independent of how this feature works, you want to have your photos in one place and have a backup (second copy) somewhere else. All hard drives will not be successful at some point - some more early, some late - never trust to have your files in any safety devices if they are on a single disc. Once you have your sorted, it would be useful that you will organize/name/tag new photos immediately if the task is relatively short and simple. I copy my photos on my internal hard drive for my camera, take a quick look with preview to see who needs some changes and then decide where to put them - either drop them immediately after naming them or bring in an editing application and then file them away.

  • Determinations of web OPA shows white screen when you use the data model

    Hello

    I use Oracle Policy Modeling 10.5.5.40 on windows 7. I use embedded apache tomcat to test.

    I have started a new project, added a simple rule:

    [b1] the parent is eligible for the benefits of compassion so

    [b2] parent has a child

    I chose 'Build and Run' selected web determinations, work very well.

    When I added a data model, created two entities, parent-child, and the child is contained in the parent as to-many, then ran the project, it won't work any more. The section that says:

    =========

    is absent.

    I also tried to open an example of "MembershipDemo" that comes with OPM, same problem.

    Any ideas how can I fix?

    Thank you very much

    Looks like you have probably changed the Boolean value "the parent is eligible for compassionate care benefits" from the global to the parent. This means that is no longer a goal because it is a single Boolean value that can be determined, it is now a Boolean value for each parent in the rule template.

    The goal that presents itself as the first screen in your interview display all the high-level objectives - that is, all objectives at the global level.

    Some possible solutions to get a goal for your interview may are:

    1. If you try to determine cbb for 1 single parent, then you probably shouldn't introduce a parent entity, use the global as a parent

    2 introduce a global "all determined the eligibility of the BCC of parents" trying to see if "the parent is eligible for compassionate care benefits" is known to all parents

    3 decide which is the highest level (s) for your interview and to introduce these Boolean values to the global level.

    everything by testing the connection I get under Error.UCM runs in other ways machine come IP. trying to connect from my local Jdeveloper.

    Test failed:

    Permission denied. Address ' XX. XX. XX. XX'(IP) is not an authorized remote socket address. (IP replaced by XX...)

    Why his error.do showing that I need to put any changes of the UCM let me know problem question

    Please give me an idea about this error and the solution for the same.


    Concerning

    To eliminate the first manifesto, see this post: fail to connect to the content if server use 'web' for the RIDC socket type and check that the other IP is allowed, amongst, IPs (you can use a mask, or type it directly) - do not forget to restart the server after the change.

    If this does not help, test, if other services such as DOC_INFO_BY_NAME can be called via RIDC, or if they have the same problem.

  • Create a site of several reactive using DW CC model page

    I have a model in place for a new Web site. Is it possible to use only one model for different structures of layout from one page to another?

    Specifically, I would like to change the boxes on different pages, so that a page has two columns, another page has three columns and the last page has a single column. Is this possible using a single model?

    I used a single sensitive model for other Web sites, but each of the pages had the same layout (two columns). There are no changes in the basic structure of one page to another.

    I'll have to explore nested templates.

    No, no, no, don't do it!  Nested models are a total nightmare to work with.

    A model should be all you need.  You just decide the number of columns on any given page child and adjust the widths of column with page specific CSS embed code as follows.

  • I can create forms in the designer, but when I use a data model, I can't interact with the form

    In LiveCycle Designer ES2 I can create a form and then preview and interact with the form.

    This guess I just build objects by dragging the pieces pre-made object on the form (for example, text field) - which I can name, wrap in subforms something - I can add actions and all is well.  When I preview the PDF, I can enter data in the fields, click on the radio buttons, making things appear that everything is great.

    But LC ES2 is based on the data driven development model by, so in my case I need a form guide as well as the form - so it's better to have a model of data created in the first place - and then create the form based on the data model - then build guide form based on the data model - it is also a good idea, and I'm cool with that.

    My problem is that when I'm building a data model (just for a quick and dirty development demo, not associated with services back-end or databases) and I create the form based on the data model - I can't interact with all objects in the preview pane form - further when I launch the workspace and call my process that contains the form - I even can't interact with the form.

    What I am doing wrong?

    Summons - I can create a form and interact with it - but If I start with a data model and generate the form based on that - I can't interact with the form (option buttons click-I can not enter data in form fields - etc) what causes this?  What should I do to use a data model and be able to create an interactive form? >

    Does anyone know what causes this problem?  It's driving me crazy.

    Thank you-

    Ben

    You do not hurt anuthing. It works as advertised. When you generate a Guide and work with a fml data model designer you will only create a static non-fillable PDF file. This is because when you import the model in the designer of the model must be turned in a schema. The schema may not represent constraints and validations can be encoded in the model. The only thing that can be maintained is the structure, so Designer forbids you to buidl an interactive form.

    If you know what you're doing, you could take the data it is generated from the Guide and merge on a XDP template file that you create (unless he models in a first time - you can use the sample XML data as a starting point) using LC forms. Edowmside, is that if there are constraints and rules you would have to code them in the model as well. That's the way it is now there, but it will improve over time, as more of the ability of the model is exposed to the XFA world.

    Hope that helps

  • A restore XP CD can be used on another model?

    Hello

    I have a Toshiba Satellite A300 with Vista computer. I'm tired of Vista and XP instead.

    So here's my question: a friend of my having a restore XP to its L300 CD (I think), can use this on my A300?
    The two bought last year.

    Thanks :)

    You must understand that this recovery image is not something that can be used on all portable models. Recovery image is created for each laptop model separately.

    Recovery image contains OS, all the necessary drivers for certain model of laptop, Toshiba specific tools and utilities and some additional software. For Satellite L300 recovery image contains drivers for hardware components in the Satellite L300 laptop.

    I imagine that your Satellite A300 a different hardware platform and probably the pilots must be different on Satellite L300.

  • What can I use a similar model to restore CD?

    My friend has the same laptop model - IE. Satellite M70-PSM70 than mine. We two bought this around the same time, about 2 years back.

    I have lost my restore CD, can I use the CD of restoration of my friend to re - install the operating system.

    Thank you much for the help.

    UNNI

    Hello

    Mr. Pacman is just.

    Each recovery CD is designed only for the special series laptop and drivers Toshiab, tools and utilities that are part of the image on the CD recovery don t run and work on all laptops.

    This is why you must use the restore CD that have been designed specifically for your model of laptop.

  • Using instrumented hammer model PCB 086D 50 with the NI9234 module and chassis OR cDAQ 9188

    Hi all

    I need to try to shock with a PCB 086D 50 instrumented hammer hammer. I use the chassis OR cDAQ-9188 with the NI9205 and NI9234 modules. The hammer is connected to the NI9234 and accelerometers are connected to NI9205.

    When I test the modules in SignalExpress I get very good results for the dog, but the accelerometers are ok. Also, if I am controlled the hammer OR Max where I have the option to activate the IEPE the result is ok. In SignalExpress, I couldn't find the option to activate IEPE.

    I have no experience using software, but I started to learn. Does that mean that I need to program the system for my setup in LabVIEW? Also, the installer of the equipment makes sense, the modules that I plugged on the cDAQ can be used simultaneously? Should I have the additional device in order to use the hammer with cDAQ 9188?

    Thank you very much

    Emina

    You can enable IEPE in SignalExpress. Here is a configuration for a single power hammer and three accelerometers a 9234-related.

    You don't mention the model for accelerometers. They are also the IEPE sensors? If so, have what conditioning of signals you added before the 9205?

    The Assistant Sound and Vibration (built on SignalExpress) contains an example of Impact Test. The Sound and Vibration Toolkit comes with a sample project for the impact test. With free evaluation period, go ahead and look at how one of these examples is implementing the configuration and the triggered acquisition.

  • Test of parallelism by using batch processing model

    Hello!

    I am relatively new to TestStand and have a question that seems to have an easy solution, but I can't understand (looked like the examples, forums, etc.)

    We use the model batch (minor modifications for reporting) but all run sequentially and have the template option set to 1 socket. I have 2 tested EHR sharing a room of temporary and 2 4145 s PXI (one for each DUT, using 1 channel as the power supply and the other three channels for the measures). I manage all the instrument in a reminder of ProcessSetup initializationg and jump into the MainSequence once the test is done I'm going in the ProcessCleanup recall and to close all references (we use digital recorders for instruments).

    I want set the template option to have 2 Sockets. So if I put the VI call that sets the temperature at will TestStand "A thread only" two starting sequences and one of them would set the temp and the other would ignore but spend once executed step.  Is there a way to tell TestStand "for USE 0, use SMU1 and USE 1 use SMU2" and go to the next temperature?

    It's a weird situation because all the examples I could find have the problem "more DUT with Instruments" so in my case, it's a problem well have .

    Thanks in advance!

    You can use the expression RunState.TestSocket.Count 0 based.  Use this value to create your EMS chain.

  • What level of security is the best in the OSI model, which is the application level?

    Hello

    Thank you

    Johan

    Hello Johan,.

    The OSI networking reference model (ISO 7498 - 1) is designed around seven layers arranged in a stack.

    The OSI security reference model architecture (ISO 7498-2) is also designed around seven layers, reflecting a high level of different requirements in the security of the network.

    In the OSI model, each layer has its own functionality and according to which it has features of different security as shown below.

    Application - authentication

    Presentation - access control

    Session - non-repudiation

    Transport - the integrity of the data

    Network - Privacy

    Data binding - insurance / availability

    Physics - certification / Signature

  • Fill ListView using the C++ model

    Hello

    Sorry to bother, I guess my question must be pretty basic, but I'm new to bb10 SDK,

    What I intend to do is to show in a listview items, I calculated in C++. (In C++, because the logic for calculating them was quite complex)

    There, in the QT doc, you have exactly what I dream of:

    https://Qt-project.org/doc/Qt-5.1/QtQuick/QtQuick-modelviewsdata-cppmodels.html

    Unfortunately, I have several questions:

    -ownership model, seems to exist. But I guess we use dataModel in our context, right?

    -J' I also need to get the declarative context of the QmlDocument which I think is correct.

    -the delegate property also doesn't seem to exist, but I understand that I must use instead ListItemComponents ( http://developer.blackberry.com/native/reference/cascades/bb__cascades__listitemcomponent.html)

    But I'm still confused on how I should provide the data for the list view.

    Now, when I expose my QList of DataObject, as described in the Doc of QT and which gives as data to the dataModel is told that he cannot "affect QDeclarativeListReference to bb::cascades:ataModel."

    So I guess I have to use a QListDataModel instead of use a Qlist <>, or?

    Well, any help in pointing me to the right documentation would be very appreciated!

    Thank you

    fill us our data model in c ++ as well.

    For this, we use a Q_INVOKABLE method that gets the listview as a parameter.

    The ListView itself is created in QML.

    ListView* listView = dynamic_cast(listViewParameter);
    GroupDataModel* model = dynamic_cast(listView->dataModel()); if (model) {        model->clear();    } else {        model = new GroupDataModel(QStringList() << "sortParameter");        model->setGrouping(ItemGrouping::ByFullValue);        listView->setDataModel(model);    }//calculate stuffmodel->insertList(stuff);
    
  • How to import in different Oracle schemas using the same model? Physical schema is different every time, so, how is this a handles that?

    Experts of the ODI,

    I use ODI 11.1.1.7.0 and transfer data to an Oracle database. So far, everything is OK, but...

    I want to reuse my current interfaces for import into different schemas in the same database.

    At the moment all the table data were imported into a single scheme under topology/Physical Architecture / Oracle / Data Server / physical schema I chose the pattern and check the "default."

    If I import now to other patterns (300 different ones), how should I configure the physical schema values for:

    Schema (schema)

    Scheme (scheme of work)

    Default checkbox? (I assume must be deselected)

    On a quick test, I left schema & schema of blank and disabled by default check box. Two interfaces work (one per table), but the third failed (my guess is the way in which the model was reverse engineering has to do with it, but don't know how to fight against it) I know how to debone a model, but if I use a pattern to do the other schemes do not work because ODI will give me a table not found. How do I work around this problem. Here is an example of the error I get after removing the default schema of the physical schema definition.

    ODI-1226: step CON_TY fails after 1 attempt.

    ODI-1240: Flow CON_TY fails during an operation of integration. This flow of charge table target CON_TY.

    ODI-1228: task failed CON_TY (integration) on the ORACLE connection signal target.

    Caused by: java.sql.BatchUpdateException: ORA-00942: table or view does not exist

    Your help is appreciated. Thank you.

    Here's how, to work around the problem of schema change the mask object Local of the physical schema on the server target %SCHEMA.%O OBJECT to % OBJECT in this way the schema is not part of the SQL at all.

    And these are the values that I use in the physical schema definition

    Schema (schema) - undefined

    Scheme (scheme of work) - undefined

    Check box default - select

    Given each user has permissions for objects it is clean and it doesn't have the schema name to reference the object, it works very well.
