[ADF, JDev12.1.3] (How to set values for the attributes 1) to create a file and 2) committing to the database?

Hallo,

in my tables and forms (created from VO istances) there are some areas for which, insert and update, I calculate and set the value programmatically when a record is created or updated.

In some cases, I put the necessary values using the 'CreateWithParams' in the workflow diagram...

In some other ones, I associate an action, a bean, a created button drag-and - drop operation 'CreateWithParams' of the istance VO...

  public String cwpButton_action() {
    BindingContainer bindings = getBindings();
    OperationBinding operationBinding = bindings.getOperationBinding("CreateWithParams");
    // here I calculate and set the needed params
    // ...
    Object result = operationBinding.execute();
    if (!operationBinding.getErrors().isEmpty()) {
      return null;
    }
    return null;
  }

And is ok if I can calculate the values for the attributes before a new record is created.

But the approach that I have used to define the attributes (for new and updated records) whose value should be caluclated after the user has filled in the fields, before committing to the database?

Thank you

Federico

Federico,

Let me first tell you that our code is activity masking errors (the cache instead of working on them).

  1. If (! operationBinding.getErrors () .isEmpty ()) {}
  2. Returns a null value.
  3. }
  4. Returns a null value.

This means that you do not check the errors at all. You must at least print a log with the error message, you receive, if you get one!

To solve your problem, you override the method prepareForDML() of the entity or entities in question. You can calculate and set the necessary attributes until they get engaged in the doDML(). Do not use doDML() because it is too late in the life cycle.

  • [ADF, JDev12.1.3] How to set the value of an attribute of VO 'max (attribute) + 1' when creating a new record?

    Hallo,

    I have a VO that selects records from a table databace where FkId = < value >.

    For example: this is the database table...

    ID RowDetNumber OtherFields FkId

    1   3     1            ...

    2   3     2            ...

    3   3     3            ...

    4   3     4            ...

    5   4     1            ...         |

    6   4     2            ...         | -VO selects these records (where FkId = 4 for example)

    7   4     3            ...         |

    8   5     1            ...

    9   5     2            ...

    When a new record is created the field RowDetNumber must be calculated with the logic of the max (RowDetNumber) + 1.

    So for the example above, the calculated value should be 3 + 1 = 4.

    I would like to know how I can calculate the value and assign to the RowDetNumber attribute.

    I did some experiments using a Groovy expression as a default value for the field, but I got only errors.

    I'm a bit confused on how I can do so a few details / examples / tips are welcome

    In particular, a small example for every possible approach would be happy.

    Thank you

    Federico

    Federico, the solution mentioned in the block will work as it only generates unique numbers without guarantee that the generated numbers are without flaw. However, if you want to use max + 1 this normally means you want to have a sequence without gap. It is very very complicated in nature. It doesn't matter what application you're trying, there is almost always room for error, ending with duplicate numbers.

    The trigger also works as the DB supports triggers on MS SQL.

    If you don't need a number of gap-less for the attribute, you can use the groovy solution and just get a number of a sequence is is guaranteed unique and greater value, like the last number that you asked of the sequence. In this way, you can have the sorted records

    ID RowDetNumber OtherFields FkId

    1  3    1            ...

    2  3    7            ...

    3  3    9            ...

    4  3    10            ...

    5  4    3            ...        |

    6  4    5            ...        | -VO selects these records (where FkId = 4 for example)

    7  4    12            ...        |

    8  5    4            ...

    9  5    6            ...

  • [ADF, JDev12.1.3] How to set attributes for new records in detail your (by program) in a panel of master / detail tabbed?

    Hallo,

    in a fragment that I have a tabs including the 1st tab panel contains an af:form (created from a master VO) while the other tabs each contain an af:table (created from a VO detail).

    When the fragment is used in design mode , I need to set some attributes (hidden) for each VO.

    I guess I can begin to insert before the fragment, in the workflow, the operation "Create with Params" for the master VO.

    But who should I set the values for the fields the other VO's hidden when the user create new records?

    Some fields of VO can be set taking values directly from session and pageFlow scope while the value must be calculated for other fields.

    Thank you

    Federico

    Retail vo was create with Potsdam too. You can use what you can do to master VO. link the button to detail to a bean and calculated method to set the parameters before running the createWithParam.

  • [ADF, JDev12.1.3] How to set a variable to bind a VO (where clause) in a managed bean?

    Hallo,

    I have a request based on VO.

    The query contains a where clause clause and a bindi variable.

    In a managed bean I would like to access the iterator of VO setting the value of the bind variable and read the result.

    I found this code it is good start, but I do not know how to set the variable binding.

    BindingContext bctx = BindingContext.getCurrent();
    BindingContainer bindings = bctx.getCurrentBindingsEntry();
    DCIteratorBinding iter = (DCIteratorBinding ) bindings.get("MyVO1Iterator");
    iter.execute();
    
    
    

    You kindly help me?

    Also, I would like to know if it is generally advisable to use VO directly in controlled beans or whether it would be best to create in the AppModuleImpl methods that do this and return the result.

    In my case for example of the VO will return max 1 plug so I'm in doubt, if the creation of a method in the AM that returns a custom class, which attributes contain values of the line of VO.

    Sorry if these questions may seem artificial, but I am a beginner, I have many doubts and so I would be happy to receive some tips regarding best practices.

    Thank you

    Federico

    You can use:

    iter.getViewObject().setNamedWhereClauseParam("yourBindVar", value);
    

    Note that this approach is used if you have bind variable in the where clause.

    To set variables bind to ViewCriteria, you must use VarableValueManager.

    This post may be useful for you: binary: how to set the Bind variable values at run time?

    Also, I would like to know if it is generally advisable to use VO directly in controlled beans or whether it would be best to create in the AppModuleImpl methods that do this and return the result.

    You must set "use VO directly.

    For example, from the point of architecture, is probably best to use the method in the model project which will set the bind variable and execute the query.

    Or you can use the ExecuteWithParams operation in your the view layer.

    In my case for example of the VO will return max 1 plug so I'm in doubt, if the creation of a method in the AM that returns a custom class, which attributes contain values of the line of VO.

    Not to complicate your life

    All VO lines are represented as ViewRowImpl class if you already have "custom class".

    Finally, you can generate your own ViewRowImpl class if it is necessary for this.

  • Action dynamic set value for the Shuffle.

    I have a Select list that bears the name of the servers. Depending on the value selected in the select list, the random component must be filled. I created a dynamic action to select the list complete the Shuffle. It does not work. Any help is appreciated.

    I gave shuffle as the name of the item assigned to the dynamic action, I chose the option to set value, set SQL statement type and the following query:
    SELECT DISTINCT MOUNT_POINT IN SERVER_DISK_SPACE_UTILIZATION WHERE SERVER_NAME =: P2_SERVER_NAME

    Thank you.

    Hi Nicolas,.

    If you use APEX 4.0 or more, then the feature you're looking for is given for the selection list and shuttle (non-random) I think!

    My assumptions are:

    Select the list item: Servers (P2_SERVER_NAME)

    Shuttle point: Mount Points

    Just what you need to do is, in shuttle item properties there is a section from the list of values :
    Set
    Cascading LOV Parent items to P2_SERVER_NAME

    List of values definition of

    SELECT DISTINCT MOUNT_POINT FROM SERVER_DISK_SPACE_UTILIZATION WHERE SERVER_NAME=:P2_SERVER_NAME
    

    I hope that helps!

    Hi Harsha,

    As you use the "tree" in the em console to test your service, it does not correctly recognize extensions/restrictions 'simpleContent '.

    I suggest that you use the 'XML' view, but if the attribute is missing then you must add it manually to the. ( Ex: ) .

  • How to set preferences for the network folder in VMWare Fusion

    I use VMWare Fusion to run a virtual PC on my Mac which I use QuickBooks to MUCH for my business. I'm trying to get the Writer of Intuit, a complementary product to work, QuickBooks statement but there need me to change the security settings on the "network drive" my files are on. Here's what he said I should do:

    "If you choose a network folder for a default save location, the system

    administrator must make some specific changes on the network and address

    some questions of local security. To open the QMD files over a network, the

    administrator must grant full trust to any executable code or to

    all Microsoft Office documents in the folder where the file qsm

    stored. Either the type of access requires a change in the code access

    security strategy for .NET framework on the computer. The

    administrator must ensure that these changes are compatible with any

    other local security policies. For more information, see Networking SIE

    and multiple users. »

    Help! How can I do this?

    Thank you

    Dawn

    I don't use QuickBooks but Google search for EIS networking and multiple users hit Albums is support QuickBooks - statement of Intuit writer (SIE) network and multi-user functionality and he said: 'because we do not recommend this, the files must be local when you work with them. It is necessary to copy the file IF you want to work with on your local disk, and when the finished work with the file, copy it to the server. "so this means to copy the file in the folder shared VMware on the Windows filesystem, as an example the office that you use also the feature and then mirrored folders when it copy in the shared folder of VMware.

    If you don't want to do that, then it seems that the major changes that need to be taken are on the side of Windows and not really a matter of VMware Fusion in itself however in the perspective of VMware Fusion, VMware shared folder should be set to read & write and is the only permissions that VMware Fusion has no control on in this regard.  Another aspect of the permissions would be on OS X and the permissions on the folder as a shared folder on VMware normally, only the owner has read & write permissions and other default permissions for reading only.  You may also need to change the permissions to read & write however what I read after looking at a few other answers the main objective research to resolve that matter Windows itself using the .NET Framework Configuration tool.

    So I really do not see this as a matter of VMware Fusion and see it in the totally as an issue security policy mainly on Windows, although the other mentioned permissions must be at least check and then only modified if necessary after that making the necessary changes on Windows is not sufficient even though as long as the folder shared VMware is set read/write & I think the rest this is totally of the Windows side.
