Dynamically add and remove the Train stop with the version 11.1.2.3

I found examples with older versions, such as http://adfpractice-fedor.blogspot.com/2011/12/dynamic-adf-train-showing-train-stops.html.

But they do not work in 11.1.2.3.

It seems that the API have changed considerably.

Please advise a similar example based on the model of the API for 11.1.2.3

Thanks in advance for your help.

Hello

I have a requirement to add dynamically different trains stop during execution, that are not part of the workflow at design time. I would like to build the train running, depending on various conditions that occur. Is this possible?

Train stops are removable only from the model train before the rendering of the first view, i.e. during the initialization of the workflow task. At a later stage, you can not delete but hide stop. The train model is created during initialization of workflow too and any train stop, which is not part of the virtually nonexistent model. In your case I think that creating a model personalized train from the ground upward and using this train are the way to go. The default metadata workflow task based implementation does not seem to do what you need it for. Alternatively, if you can predict the maximum number of train stops, you can design them at design time, and remove those that you need not during execution using a HashMap of reference in the configuration of the train stop and check the values of the hash table initialization.

Here is a write up on top of the trains I've done in the past: http://www.oracle.com/technetwork/issue-archive/2011/11-sep/o51adf-452576.html

More documents that you will find on http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html ADF Code corner (just search train)

  • DELETE THE GAMES ADD AND REMOVE _

    Im trying to remove some games add and remove prog but when you click on delete, nothing happens, I want to put on an external hardrive to make room on my laptop, can someone help me with this?

    Hello

    Some programs are not designed to installation of Microsoft standards, and have their own installation/uninstallation program. They have just added a line to register to make is appear in the menu of programs and features.
    You might look into the menu all programs for the game that you want to move and see if there is an option to uninstall it it.

    If the game has used the Windows Installer Setup program, you can use the Windows Installer Cleanup utility to remove registry items 'more', but you still need to delete the files and folders of programs. You can then reinstall. This may not be the cleanest solution however... depending on how well the developer has created the installation routine. The re - install the game should clean up some things.

    Download the W I Cleanup utility: read the article, although it is ex officio, it relates to most of the other programs as well.
