Hi Srikant,

Can you post the code in onActionShowCallWindow of your MainView.java. The line no 150 is giving error.

hi

this error might come if you use say a pop up WD window and also open an WD application in an external window one after the another. both of them use the interface view hence that error. this is one such condition may be if u can give details of your project i can help.

Hi Srikant

This comes when ever you are using the component more than once. I guess "CallWindowInterfaceView" you are trying to embed in 2 windows.

If you want to go away with this have 2 different used components with 2 names with the same component embeded.
