Why is not updated when you create or whole part of delete trigger?

Hey there ' All,.

I have a Page with links. These bindings are based on components business ADF, pretty standard stuff. On this page, I have an af:panelCollection. It contains buttons to create, remove, commit, and roll back. All those assigned to their respective shares in the ADF business components-based binding. In this collection of Panel there is also an editable table. It was created by dragging the view from business components in the collection of panels. ADF automatically created the iterator in the definition of the page.

It is the source of the fragment:

For the facts so far.

Now, my experience with it:

Whenever I click on the 'New' or 'Delete' button, it first calls the partial relaxation and then perform the action assigned to the button I clicked. I thought this because of the following behaviour:

1. I load the page

2. I click on the 'New' button - nothing happens

3. I click on the button "New" once again - a single line appears

4. I click on the button 'Delete' - nothing happens, still a line it

5. I click on delete - disappearance of the line

In order to engage without an error in database fields, that I need:

1. load the page

2. click on the button "new".

3. click again on the button "new".

4. click on the button Delete

5. fill the new line

6 validation

What I tried:

1. triggers, of course, I thought that business components and links stuff would be here to refresh everything about an action.

2. I also tried in the PageDef not caching the results of the underlying iterator from the table. However, this only leads to an exception during step 3 of my 'to be able to commit without a basic error of data fields that I".

I hope you can tell me what is the problem or you have any suggestions or advice.

Thanks in advance

You should always use CreateInsert operation declaratively add new line to af:table.

"createInsert" has a problem: he inserts. I know almost no case (at least in a well-designed database location) when possible, insert without data. As it is in my case, so createInsert will not work, I get an exception from the database during insertion.

It will insert line collection in British Colombia ADF, not in the db table.

Framework will display data from db only when you call commit operation (or if you call transaction.postChanges ()) programmatically.

Thus, the workflow must be:

-Invoke CreateInsert

-Fill in all the mandatory attributes for this ViewObject

-Don't commit / rollback

  • Why the Amazon icon will not appear when you create a shortcut

    When I create a shortcut to a Web site; instead of the web logo, I get the blue standard & green "globe".

    How can I correct this (windows 7)?

    Thank you

    Clyde

    Hello

    You are welcome.

    Shortcuts to sites will initially their own custom icon when you create a shortcut. This icon is called a "favicon.ico" and is stored in the temporary Internet files (TIF) cache, which is where all website files, are stored when you visit them.

    When the user performs a maintenance and removes the TIF cache, all these custom icons are removed with everything else. This will cause the icon of Internet Explorer by default to display on these shortcuts. This also occurs when the maximum allowed disk space has been exceeded and that the files are deleted automatically to maintain the use of disk space.

  • Fashion design not available when you create or open a file php - CS5

    I don't know if this is a bug or not.  When I create a new php file, it opens in code view.  Options display in the design or the code and design mode are disabled.  If I reset the workspace, didn't matter what workspace I at the time, then the file is displayed in code and design, but to display in the design or code and design options are disabled.

    If I select the display code mode, the design view disappears (as expected), but there is no way to get to design or coding and design without resetting the workspace.

    Is this considered normal?  The help system does not imply that there is a restriction on the views of a PHP file.

    Thank you

    If I open a PHP file or create a new one, it opens all three available. (CS5 Mac and Windows Vista or 7). If I open a JS or CSS file, they offer in the code, but PHP opens as a XHTML until I save it as PHP, and even then it always opens in any mode I finally had his opening.

    There may be a preference that requires a reset. Perhaps someone else knows more on this.

  • Members parents not updated when you run tot.

    I have a scenario where even if low level members change the parent members are not updated when we run an agg

    For example, if low level member was 150 and we run the aggregate numbers are fine. If the Member of low level is passed to #Missing parent members are not updated when we run the tot.

    IN the script below, we use DIM(COstCenters,SpaceTYpe) CALC

    My concern is the SET FRMLBOTTOMUP ON setting I use, because it looks like he will ignore this block. How can solve this problem without affecting the performance too. For example using SET CREATEONMISSINGBLK WE could help, but will have an impact on performance

    Here are the details of the script

    SET FRMLBOTTOMUP

    The first thing I would try would be to add that the parameter SET to AGGMISSG. IF the database is set to off then if all children of a member are missing then the parent will retain its value. If aggmissing is enabled, then it always overwrites the values parent with the calculation of the values of the child.

  • Pages of tabs not updated when you add a new blank page

    4.2.2.00.10

    When adding a new blank page and specify to use an existing tab, the tab specified for re - use is not added as a list of pages associated with this tab (configuration: tab also run for Pages in the app Builder: 4000:4305).

    I tried adding a new type of page as SQL report and the value of the page successfully is added to the parameter, also running for the tab Pages. Without tests of each type of page, probably so it's just empty pages.

    Appear to affect tabs of level one and two.

    Hi Trent,

    Thanks for that bring to our attention. The question doesn't seem to be specific to the creation of blank pages. I connected the bug 16729276 to follow up on this matter. In the meantime, the workaround, which I'm sure you already did, is to edit the page and update tab to make reference to the new blank page ID.

    Kind regards

  • DataGrid does not update when you use the tabs

    I have a panel with a TabNavigator with two legs (VBoxes). Each VBox contains a DataGrid control. I update the dataprovider of two DataGrids using a table for each in ActionScript, but only the data of the selected tab (default index 0) grid is updated, and the second tab DataGrid generates an error (TypeError: Error #1009: cannot access a property or method of a null object reference) and is not up-to-date. Any help would be appreciated. Code attached.

    Set the creationPolicy = "all" because the children of the other tab cannot exist until they are displayed initially.

    creationPolicy = "all" might affect performance, and if so, you can initialize the other children of the tab, perhaps in the events to initialize or creationComplete TabNavigator.

  • Previously purchased songs do not appear when you add a whole album with music subscription

    Hello

    What is happening with a few albums in my music library: I already bought only songs from these albums, then after the signing of Apple's music, I added the entire albums to my library. However, the songs already purchased are now missing.

    When I search on the Apple's music album, it shows that all the songs on the album is available in offline mode on my device, except the already purchased song. If I type '+' at the top of the page or by clicking on «...» ' then '+' next to the missing song, I see the notification '✓My Music' and the '+' appears instead of the download symbol, and no changes are made to my library.

    Any help is appreciated!
