[neha_mahanty]

HI All,

I am new to web Dynpro's . I was going through this link

https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/20d2def3-f0ec-2a10-6b80-877a71ec...

to create a Pop up window using web dynpro.

After I deployed and run my application . I got the starting page which is a button and when I click the button it should open the pop up window.

But When I click the button , I am getting this error:-

Error Description:

Hi Neha,

Just see the following line of code :

IWDWindowInfo windowInfo = (IWDWindowInfo)wdComponentAPI.getComponentInfo().findInWindows("PopWin");

Here the string parameter "PopWin" is the name of the window that you have created at design time to display the popup window. Please check if the parameter that you are passing here is the same as your window name and it is also case-sensitive.

Hi Neha,

It might be a problem in creation of window in your action button implementation. Check your code fo creating modalwindow

IWDWindowInfo windowInfo = (IWDWindowInfo)wdComponentAPI.getComponentInfo().findInWindows("PopWin");

IWDWindow window = wdComponentAPI.getWindowManager().createModalWindow(windowInfo);

window.setWindowPosition (300, 150);

window.show();

Hi,

Check Window name. This exception indicates window name is incorrect.
