Hi all,

looking for some guidelines, examples on how to leverage the _trace files to properly configure "Open Source/Generated File"

I do have one dsl files that produces 2 java files. The traces seem like they are properly mapped but when I do Open Generated for a given line in the DSL file it proposes 2 java files. I would like to narrow it down to one.

Similarly when from a given region in java I do open source, it does not position the cursor correctly.

Any hint?

What do you mean? Yes I do generate two files but I want the cursor to be positioned in the right line of the source file. I will debug OpenGeneratedFileHandler
Thanks

Yes I confirm, that findDerivedResources does not take into account where the cursor is positioned in the source file to look it up. So actually, it does not use the traces to look it up.
Hopefully this will not be a problem to enable debugging.

Would you mind pointing me to some resources to enable debugging? Right now I cannot add breakpoints in the DSL.

I guess that it should in turn add breakpoint in the underlying java code
