RE: [mdr-users] Newbie: correct way to find usages of one class by another

Martin,

Whenever I try to use the Collection returned from JavaClass.getReference I
get:

org.netbeans.mdr.util.DebugException: Invalid key
	at
org.netbeans.mdr.storagemodel.MdrStorage.getObjectsFromIndex(MdrStorage.java
:725)
	at
org.netbeans.mdr.storagemodel.IndexImmutSet.getObjects(IndexImmutSet.java:66
)
	at
org.netbeans.mdr.storagemodel.IndexImmutSet.toArray(IndexImmutSet.java:101)
	at
org.netbeans.mdr.handlers.IndexSetWrapper.toArray(IndexSetWrapper.java:129)
	at java.util.ArrayList.<init>(ArrayList.java:137)

I have tried this with a couple of different JavaClass', and besides the
error looks like it isn't something that should be in production code?

Any help would be greatly appreciated,

Thanks,

Richard.

That's weird, WhereUsedQuery should work (otherwise the Find Usages 
feature would not work). Anyway, if you want to find usages 
programmatically, it is better to call JavaClass.getReferences() 
(WhereUsedQuery is kind of heavy-weight, since it wraps the results by 
RefactoringElements).
