RE: [cdt-dev] Bug 142464 : NullPointerExcepetion inCElementAdaptorFactor

["Leherbauer, Anton" <Anton.Leherbauer@xxxxxxxxxxxxx>]

Hi Janees,

 

I am currently starting to do the same thing for CDT 4.0, see also

https://bugs.eclipse.org/bugs/show_bug.cgi?id=140337,

and I ran into the very same problem :)

AFAIK, the adapter factory cannot be disabled by another plugin.

I don't know if a committer is willing to apply your patch for 3.1, but I would

certainly support this as it is quite a trivial fix.

Subject: [cdt-dev] Bug 142464 : NullPointerExcepetion inCElementAdaptorFactory.

While trying to integrate Common Navigator and CDT, CElementAdaptoryFactory throws null pointer exception.
 
This happens when CommonNavigator tries to adapt CModel to IProject, it checks if there is an adapter for CModel to IProject, The adapter manager will return CElementAdaptorFactory as oe.cdt.ui says all ICElements are adaptable to IProject using this factory.

On adapting CModel to IProject, CElementAdaptorFactory calls CElementAdaptorFactory.getProject(ICElement) which returns ICElement.GetCProject().getProject(); But CModel.GetCProject() is null for CModel; hence the above call throws an exception.

One solution is to check for null before calling getProject();

Question: Is there a way to exclude CModel to IProject adapter through plugin ?

I have attached a patch for the said solution.

Thanks and Regards,
Janees
