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

Martin,

Thanks for that: I deleted the 'mdrstorage' folder and it seems to run okay.
However, my problem now is I cannot make head nor tail of what is returned?

If I do:

	JavaClass myClass = ...resolve class...( "com.foo" );

	myClass.getReferences();

I get back a collection of ElementReferences, but any which way I try to use
these ElementReferences (I've tried toString(), getName(), getElement(),
getElement().getType().getName()) they only seem to ever return information
about 'com.foo', not the classes that are referencing it! All the
ElementReferences are of type MultipartId$Impl?

How am I supposed to use the collection returned by getReferences() to
determine who is referencing my class?

Many thanks for all your help over the months,

Richard.

Hm. I think I've never seen such error. Try to clean 
$nbuserdir/var/cache/mdrstorage dir and run your code again. If you get 
the same behavior consistently, please file a new issue in issuezilla 
and provide any information you can (at least attach your messages.log 
from $nbuserdir/var/log/).
Thanks,
Martin
