[platform-dev] NullPointer Exception thrown on creating a project

["Banerjee, Ashish Kumar (STSD)" <ashish.banerjee@xxxxxx>]

Hi,

 

We have written a plug-in component and we have our customized the project creation, file creation.

We have written our plug-in using Eclipse 3.0.1 and now when I tried migrating the component to Eclipse 3.1M6, following is happening:

 

1) The moment, I am clicking on Create project icon from Eclipse action bar, I am getting the following stack trace and project creation wizard doesn't come up. I tried debugging it but it is coming out from WizardDialog.class.

Suprisingly, if I am doing File->New->Create my project, then I am able to see the wizard and I can create the project.

 

2) For file creation, I am able to bring up the dialog using both action and File->new->MyFile.

 

Can you please help? I am clueless, why I am getting such error.

 

 

 

The stack trace is as follows:
