Cannot debug: exception when selecting interpreted modules

[ethertricity]

Hi, I'm trying to debug a node on my machine from Erlide.

I get the following output in the target node console upon clicking any source file in the "Interpreted Modules" dialog:

Could you please update to the latest nightly (I have just built one) where we have updated the debugger to the one in R15? I think that this issue is fixed there.

[ethertricity]

Yes, it works now! Thanks Vlad.

If I click out of Interpreted Modules and back in, the entries are all cleared (i.e. it doesn't remember them). Is this expected behaviour?

[vladdu]

Wonderful!

The interpreted modules view is not really working. At the moment, the only way to make a module interpreted is by setting a breakpoint in it.
