Pop-Up window error

[Former Member]

Hi all,

On Click of Continue button i want to show a pop-up window as "Do u want to continue" with 2 buttons as OK and Cancel

the code i wrote is given below

IWDControllerInfo controllerInfo = wdControllerAPI.getViewInfo().getViewController();
String dialogText="Do you want to Continue;

  IWDConfirmationDialog dialog =
		wdComponentAPI.getWindowManager().createConfirmationWindow(dialogText,controllerInfo.findInEventHandlers("ok"),"ok");
     	
     	  dialog.addChoice(controllerInfo.findInEventHandlers("Cancel"), "Cancel");
	  dialog.open();

By deploying it is giving error as

Error stacktrace:

Hi,

have you created an eventhandler with the name "ok" and "cancel"?

Hi Dennis ,

I created EventHandler methods which are given below...

 public void Ok(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
  {
    //@@begin Ok(ServerEvent)
      //@@end
  }
 public void Cancel(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
  {
    //@@begin Cancel(ServerEvent)
    //@@end
  }

Ok,

it seems taht you try to create the confirmation window in the view. But I would say it is better to do so in the Controller.

Maybe that is also the reason why this is not working, you are trying to access the Window Manager in the View. maybe you should use the window manager of the component controller like:

wdThis.wdGetComponentController().wdGetAPI().getWindowManager().createConfirmationWindow()

HI padma,

The action u have give is case sensitive "ok" .Give the correct action as "Ok".

Hi Padma,

According to your code event handler name should be <b>ok</b> and <b>Cancel</b>

String dialog = "Put Dailog Message";

IWDConfirmationDialog confDialog = wdComponentAPI.getWindowManager().createConfirmationWindow(dialog,wdThis.wdGetAPI().getViewInfo().getViewController().findInEventHandlers("Ok"),"OK");

IWDEventHandlerInfo CancelEventInfo = wdThis.wdGetAPI().getViewInfo().getViewController().findInEventHandlers("Cancel");

confDialog.addChoice(CancelEventInfo,"Cancel");

confDialog.setTitle("My Pop Up Window");

confDialog.setWindowPosition(350,150);//Change x,y as you want

confDialog.setWindowPosition(WDWindowPos.LEFT);

confDialog.show()

Also Check

<b> at com.sap.tc.webdynpro.SearchView.onActionsearch(SearchView.java:165)</b>

Hi,

Conformation window is comming on click of continue with 2 buttons as Ok and Cancel..

But on click of continue it has to go prevoius view and on click of cancel it has to be in that view only...

So in the Ok and cancel methods i wrote

public void Ok(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
  {
    //@@begin Ok(ServerEvent)
    wdThis.wdFirePlugToView2();
    //@@end
  }

  //@@begin javadoc:Cancel(ServerEvent)
  /** Declared validating event handler. */
  //@@end
  public void Cancel(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
  {
    //@@begin Cancel(ServerEvent)
    //@@end
  }

but for me the popup window is comming in the previous screen means the screen which has to be dispalyed after clicking on Ok button

Hi Padma,

If you have created the actions and still getting problems, check the names of event handlers in the code. They are case-sensitive.

<b>Ok</b> but you have given <b>"ok"</b> in the confirmationDialog eventhandlers. Please change it as <b>Ok </b>

regards,

Siva
