String dialogText1 = wdContext.currentOutputEICaseElement().getEv_Eic_Case_Number();

IWDConfirmationDialog dialog =

hi

this is the code for pop up.

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

String dialogText = "The email was successfully sent!";

IWDConfirmationDialog dialog =

wdComponentAPI.getWindowManager().createConfirmationWindow(

dialogText,

controllerInfo.findInEventHandlers("ok"),

"ok");

dialog.addChoice(controllerInfo.findInEventHandlers("newEmail"), "new email");

dialog.open();

but in your code

wdContext.currentOutputEICaseElement().getEv_Eic_Case_Number();

it returns null value.

That might be the problem.

Check that once value is coming or not.

Thanks

Lohi.

Hi

could you check

wdContext.currentOutputEICaseElement().getEv_Eic_Case_Number();

is this statment the value s coming?

null pointer means value is not coming by the line mentioning in the log.

Check that once.

Thanks

Lohi.

Hi,

Wher u have written the code for closing the window.

[Former Member · Accepted solution]

Hi

You can write the code in close button action.

for the sake of created window instance would be destroyed.

Thanks

Lohi.

[Former Member · Accepted solution]

The code for closing is wrotten in the pop-up itself, this is a seperate view.

The pop up is working now, I get the number, but closing the pop-up is still an issue

HI

Where is your window instance is located in context.

I think it is in some folder.

IWDWindow window =

wdContext.current<ur window instance foleder name().getWindowInstance();

window.destroy();

it might helps otherwise post your code.

Thanks

Lohi.

to close the popup

IWDWindow window=(IWDWindow)wdContext.currentExternalWindowElement().getWindowInstance();

window.destroy();

Or tell me whas is the line of code(Pop_up.java:147).

Thanks

Lohi.

public void onActionOK(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

(line 147) {

//@@begin onActionOK(ServerEvent)

IWDWindow window=(IWDWindow)wdContext.currentExternalWindowElement().getWindowInstance();

window.destroy();

[suresh_krishnamoorthy · Accepted solution]

Hi Dresen,

Try this:

IWDWindow window =

wdContext.currentcontextElement().getWindowInstance();

window.close();

Regards, Suresh KB

[Former Member · Accepted solution]

same result

[sridhar_k2 · Accepted solution]

Hi,

You can try this.

Create a context varialbe(WindowInstance) whose type is

"com.sap.tc.webdynpro.services.session.api.IWDWindow".

IWDWindow window = wdContext.currentContextElement().getWindowInstance();

window.destroy();

Regards,

Sridhar

Try this: For context node "ExternalWindow", set cardinality=1:1 and selection=1:1.

Do you access this node from different view controllers? If that's the case, define it in a custom controller or in the component controller context and map it from both view controller contexts.

[Former Member · Accepted solution]

Hi

Use this code in your close action.

And mention the cardinality and selection 1..1 as mentioned Armin post.

U can do this your Window instance folder.

IWDWindow window = wdContext.current<your window instance folder>Element().getWindowInstance();

window.destroy();

This should work, I tried.

Thanks

Lohi.
