popup usage in wdDoBeforeNavigation

[former_member190457]

Hi everybody,

as per WDJ best practice, I want to centralize error and UI message handling in the wdDoBeforeNavigation of the root component controller.

In my project error handling mandatorily includes popup messages. When I try to open a popup in the wdDoBeforeNavigation I get:

com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: There must be something wrong, phaseLoopCounter: 21 

Can anyone please explain this error and/or suggest a different approach?

Thanks, points will be awarded, Vincenzo

hi thanks for your reply.

I have no handlers, I am using the following code:

IWDWindowInfo winInfo = wdComponentAPI.getComponentInfo().findInWindows("DummyPopup");
IWDWindow popUpWindow = wdComponentAPI.getWindowManager().createModalWindow(winInfo);
popUpWindow.setWindowPosition(WDWindowPos.CENTER);
popUpWindow.setTitle("hello");
popUpWindow.show();

I tried to move the same code in wdDoPostProcessing but the same happens.

Unlike the post you mention, actually popups aren't displayed at all.

any suggestion?

thanks, Vincenzo

hi!

instead of creating modal window try with other windows like confirmation window .

you can use this kind of code as it is been done for save .

IWDControllerInfo cntrl_info = wdControllerAPI.getViewInfo().getViewController();

IWDConfirmationDialog confirm = wdComponentAPI.getWindowManager().createConfirmationWindow("data saved", cntrl_info.findInEventHandlers("save"),"save");

confirm.addChoice(cntrl_info.findInEventHandlers"ok"),"Confirm");

confirm.setWindowSize(250,100); confirm.setWindowPosition(100,100);

confirm.show();

Hi thanks for your prompt reply

However, the code you mention can be executed only in a view controller.

On the other hand, view controllers don't have the wdDoBeforeNavigation method.

I would like to use view-based popups as they are much more powerful and can display also warning/error/success images.

Thanks, vincenzo

Actually there was a subtler problem.

The popup was triggered if an instance variable was not null, starting a nested ("recursive") phase model execution.

The instance variable was not reset after the first execution and so an infinite recursion would take place.

Thanks, regards

Hi,

Try this code

IWDWindowInfo winInfo = wdComponentAPI.getComponentInfo().findInWindows("DummyPopup");

IWDWindow popUpWindow = wdComponentAPI.getWindowManager().createModalWindow(winInfo);

popUpWindow.setWindowPosition(300,300);

popUpWindow.setTitle("hello");

popUpWindow.show();
