Value of attribute not copied after WDCopyService.copyElements

Hi,

I am trying to copy values from the cutom controller context to the view controller using WDCopyService.copyElements(srcNode, destNode).

I can see the values in the custom controller in debug mode.

But some the attribute values are not present in the view controller after doing

WDCopyService.copyElements

I would need your expert advice.

Thanks

Asif
