Modules of the app and objects of entity-caching issue

Hello

I'm working on an application that allows users to distribute scholarship funds to students. My main page uses a table based on a view object App Module has to display the information of the student. The attributes of this VO are based on an entity object, let's call it "foo." This page has a dynamic region popup to allow to define details of the scholarship... the called pre-existing taskflow creates new lines in the objects view App Module b, whose attributes are also mapped to EO foo or mapped to an EO with associations with the foo.

So, with the new lines created, I quit my dynamic region, re - run my application Module has VO, and... no line. It is my understanding that, even if the your were in different Modules App, the fact they were using attributes based on the same EO would allow the lines created to persist in a cache of the entity. Within taskflow the dynamics of the region, there is another outcome where lines are displayed in VO that exists in the App Module b... so I'm pretty confident that my lines are created...

Is there some steps needed to pass data between modules app? Is it impossible? I lose the EO cache when switching between taskflows? Or something else could be the problem?

Thank you!

Unfortunately your understanding "that the your were in different Modules of the application, the fact that they used the same EO-based attributes would allow the lines created to persist in a cache of the entity '... is incorrect.

As you are 'reuse' OS through the AMs, the OS cache is instantiated two times, one for each AM, because AMS have entirely separate transactions (to the AMs of the nested exception... but you don't mention you have nested for your AMs so I figure that's irrelevant for you). This is the point of the AMs, separate transactions, so the behavior you're seeing. If you made your sub 2 the same AM, you would be able to reuse the cache of 'foo' EO. Nesting potentially your AMs under a parent AM would have the same effect.

Note, it becomes a little more complicated in a workflow scenario, because workflows can instantiate separate transactions on a single AM optionally.

  • Content of PersistenObject disappears after you remove the app and the new facility

    Hi guys,.

    I discovered the following problem with my app:

    1. when I update app with new version all persistent data is stored very well.

    2. when I delete the app and install it again - some of the persistent data disappears, some is always there.

    I think it depends on who what is persisted. If there are classes of applications store is deleted on uninstall, if there are classes of system store will not be erased.

    Can you tell me about the resource, where it is described?

    Thank you

    I found:

    When you use the persistence model of BlackBerry, data is removed only if the store contains data that belongs to the deleted application.

    For example, if an application stores an object with a package named com.mycompany.application.storage and no other application on the BlackBerry smart phone makes reference to packaging, permanent storage and the deleted application are removed.

  • Apps that worked perfectly well today are grayed out now when I connected to wifi and I can't delete the app and it just says: 'pending' Please help

    HI so I recently did a restore from my old iPhone to a new 5s 5s.

    on this operation, I had to install all my apps again as usual, I did this on the wifi and then had to leave my place and obviously they can not download correctly. Once all applications have been downloaded perfectly well, today my application was grey and when I typed on it, it says waiting?

    on further inspection I went to my app store and tried the app said see if I could redownload the app and he just said 'open' and when I click on open it did nothing.

    I also tried to remove the application and I can not.

    Please advise on what to do as this application contains important information and I need it urgent.

    Kind regards

    William

  • Is it possible to get rid of the splash screen, the screen of the app and go straight to the desktop?

    Original title: I h8 windows 8.

    I don't like having to go through two screens to start my computer and two screens to close.  Add the startup of the screen and the screen of the application tiles does improve performance, they interfere. I don't see what's the difference between have icons on my page tiles and the application windows on my screen, except that the former is more efficient.

    Is it possible to get rid of the splash screen, the screen of the app and go straight to the desktop?

    Easy solution for this. You can download the Start button after the installation your computer will work like all the other previous windows and ordinarysoft.com. You will have all the programs with your button/start menu 'start '. The installation start opt to escape metro and you never see it again. Tell me if you have any problem to find the button start or downloading from the link I told you. Its free of cost.

    It's crazy that I paid for the service. logged on to the site. Download the Launcher. has attempted to launch the app and... nothing?

    what the devil!

    We are sorry for the inconvenience this is for you. Can you please if you did the migration from a previous version of MAC OS in Yosemite (10.10.1)? If so, you have problems at the launch of the Desktop Application? If so, there are two steps available to us.

    (1) first of all, please check the permissions on the folder/library and see if you have the full read & write access. If you do not, I would ask you to have a conversation with Apple support.

    (2) if the permissions are all very well on this issue, please check the same on folder ~/Library as well.

    If all goes well, I would ask you please reinstall and try again.

  • No methodActions in a module of the App application and access of backing bean

    USNG ADF 12 c on Windows 7.

    I've inherited an application that does not have methodActions defined in the pageDefs and uses a custom method to get the instance of the app module (return (appModule) getDCBindingContainer () .getDataControl () .getDataProvider ()) by supporting beans.

    The latest I can remember seeing in a document is a bad practice.

    All the places where the app module instance is acquired should be changed to methodActions? Or am I worried for nothing here?

    Thanks for your opinion!

    Kind regards

    Dave

    ^ Well, for me, this is a no go to use the code you provided. You should not use the application module in the bean because it tends to violate the MVC pattern. You may have to implement a method of the application module, add to the interface and use via the pageDef as an action method customer. This seems to be more work but allows to encapsulate the business logic in the view layer. The advantage of using methods defined in the pagedef, is that they are handling errors the same way. There is no need to handle the error yourself. The framework know dangels done in methods (if you do not use pl/sql to change the db directly and does not synchronize the frame later).

    request module is the interface that everyone should use.

  • What is the best way to move the data from the app and Server data structures?

    Hi guys,.

    I developed my application locally with Apex 4.2 and Oracle 11 g XE on Windows 7. Not far away, it is time to move the application to a server Oracle Apex. I guess that Exim is the way to go app. But what about the APA tables and data (tables/as 'customer' and 'account' created specially for the application)? I've been using a modeling tool, so I can run a DDL script to create the database server data structures. What is the best way to move the application data on the server? Is it possible to move the structures and data in a single process?

    Thank you
    Kim

    There is probably another way to get here, but in Developer SQL, on the navigation tree, expand objects until your table, right-click, and then click EXPORT... you will see all the options. It is a tedious process and it sucks IMO, but yes, it works. This is zero especially because 1) it's a table at a time, 2) If your data model is robust and has constraints and sequences and triggers, then you will need to disable all for the insert and we hope you can re-enable constraints, etc. without hitch (good luck, unless you have only a handful of tables)

    I prefer to use the oracle EXP command-line to export an entire schema, then the server target, I use IMP to import the schema. In this way, it is almost true. This makes the dirty life if you develop multiple applications in a single schema, and I felt pain - however - it is much easier to drop the tables and other objects is to create them! (thus, even if the process of EXP/IMP moved more than you wanted to "move".. blow everything you don't want on the target after the fact...)

    You can use method datapump oracle too.

    If not, what can be done, IF you have access to both servers of your instance of SQL developer (or if you can tnsping both already from the command line, you can use SQL * MORE), is to run a script that will identify the objects of your applications apex (usually by the prefix for the names of objects, such as % EBA_PROJ_ etc.) and do all the manual work for you. I've created a script that does just that so that I can pass data from dev to prod servers on a dblink. It is difficult because of the order that must be executed to disable constraints and then turn it back on and of course, more complicated if don't always precede you ALL your "objects demand '... (tables, views, triggers, sequences, functions, procs, indexes, etc.)
