Re: [morph-user] Converting graphs with Collection

[Matt S. <sga...@us...>]

Hi Matt, thanks for using Morph!

The PropertyNameMappingCopier is always getting picked up because by 
default the copier specifies that it can copy any object to any other 
object.  You're probably putting in your PropertyNameMappingCopier first 
and your ContainerCopier second.  This will cause the PNMC to always 
kick in.  There are two simple solutions you can try, both of which 
should work:
- Make the PNMC class less "greedy" so that it only tries to transform 
some types of objects.  You can do this by modifying the sourceClasses 
and destinationClasses properties.
- When you configure the DelegatingTransformer, use the CC first and the 
PNMC second so that the when a collection is encountered, the CC kicks 
in before the greedy PNMC tries to perform the transformation.

Either one of those should work, but if you keep having trouble don't 
hesitate to post a follow-up question!
