error message

In the view controler i have an action and this needs to trigger an other view in a new window.

code i used

wdThis.wdFirePlugToSeachhelpPos();

IWDWindowInfo win=wdComponentAPI.getComponentInfo().findInWindows("SearchHelpPos_View");

IWDWindow wind=wdComponentAPI.getWindowManager().createWindow(win,true);

wind.open();

What is wrong:

java.lang.NullPointerException

Hi Eoin,

Try to comment plug fire (wdThis.wdFirePlugToSeachhelpPos(); ). May be it is the problem. And check whether window contains any view.

Best regards, Maksim Rashchynski.

Hi Cronan,

can you post the code which is written in onAction part? and mention the line number 249.

[Former Member · Accepted solution]

//@@begin javadoc:onActionNextPosviewSubmit(ServerEvent)

Line 249 //@@end

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

{

//@@begin onActionNextPosviewSubmit(ServerEvent)

wdThis.wdGetOm_Webforms_CustController().NextStep();

wdThis.wdGetOm_Webforms_CustController().InvisibleAdditionalinfoCont();

wdThis.wdGetOm_Webforms_CustController().visibleSubmitRequest();

//@@end

}

Hi Eoin,

In the line >>

IWDWindowInfo win=wdComponentAPI.getComponentInfo().findInWindows("SearchHelpPos_View");

>>>> The argument you have to pass for <b>findInWindows()</b> method is the window-Name (not the <i>View</i> name). Is '<i>SearchHelpPos_View</i>' the window-name (window which is containing the View) ???

From the name (=SearchHelpPos_View), i feel that it is view's name... !

Hope it helps!

Regards,

SK.

Hi Eoin,

This createWindow() code seems to be good. Can you please check in other lines of code. If you are doubting on this particular method, just comment calling these lines and test the rest. Hopefully, you can find out where is the error.
