Re: [TM4J-users] Basename Merging

[Kal A. <ka...@te...>]

That is strange - looking through the code, the name-based merging code
in the in-memory backend does check for this property when a scoped name
changes. I wonder if the parsing is somehow bypassing this (it shouldn't
be...) I'll have to take a closer look and maybe try and write a test
case that fails for this.=20

Cheers,

Kal
