Null Pointer Exception [message #1794078]

Hii

Can anyone explain me how to get rid of null pointer exception. Im explaining my problem in detailed steps:

I have created modelling project and applied view point specification to that .Now my project will have two files
1)one file with specific metamodel wizard
2)one with representation.aird file

At first I can create the nodes under opening the new representation and saving that Im closing the runtime. Now again if I try to open the runtime nothing is there in my files It showing as Null Argument and under that
.aird file the representation are deleting once we close the .aird file

Im attaching the exception I got and the screen shot under .aird file

org.eclipse.core.runtime.AssertionFailedException: null argument:

Hello,

I am not sure to understand what you mean by "1)one file with specific metamodel wizard". How did you add your semantic model to the Modeling Project?

Regards,
Steve

This is strange, a representation is supposed to appear with a "grayed" label if it was created on a semantic element that was deleted. However, you created it on the root semantic element that is still here. How did you install your metamodel and your Viewpoint Specification Project?

Steve

Hi Steve

Yes I have selected my model and applied viewpoint specification same as basic family example which they have provided

I analysed that based on representation.aird file the diagrammatic representation are loading .In my case my representation.aird file is not writing correctly may be because of that diagrams are not loading .Im not sure what is wrong with my model(my model is having multiple packages )

If Possible I will connect you through Skype.Please help me on this

Im trying to use sirius to my model

HI Sharmila,

Look at your error log while creating your diagram, your node, saving, closing and relaunching you should have some errors.
Also validate your design to ensure it is correct: right click on the viewpoint item>validate.

With that basic family design also on validating the design(persons) Im getting so many errors Im attaching that screenshot . For my design also I have got errors can you Please confirm me may be because of my design validation Im getting errors or due to model ?

Please help me on this

I can't confirm anything since basic family is working. It could. It could be something else.
Have you checked your error log like I suggested?
