@stephanmg how did you fix your console app issues? do you have a fix for this one?

stephanmg commented 9 years ago

@miho for the above issue I don't have a guess, sorry, I circumvented only the resource path issue in console apps a different way. but your fix for issue #25 is more appropriate.

bsumirak commented 9 years ago

I cannot reproduce this. And I do not see why DomainAndFunctionDefiniton.java:90 which is

String subsets = "";

should result in a NPE. However, it does not work for me either, failing with:

@miho Maybe you understand what this one means?

stephanmg commented 9 years ago

@bsumirak: did you update your branch? you need to export the edu.gcsc.vrl.neurobox package.

I'm sorry, I did not export all sub-packages of the edu.gcsc.vrl.neurobox package explicit, I think this should be mandatory @miho, shouldn't it?

miho commented 9 years ago

@stephanmg check the documentation There are exportPackage-methods that automatically export subpackages.

bsumirak commented 9 years ago

@stephanmg It appears you really have to export all sub-packages individually. Having done this, I can now reproduce the described error. I will look into it.

stephanmg commented 9 years ago

@miho: ah, that's great. thanks. seems I need to update my VRL :) :+1: @bsumirak: great!

bsumirak commented 9 years ago

Fixed. Bug was due to unimplemented getValueAsCode() of FunctionDefinitionType in VRL-UserData plugin.

bsumirak commented 9 years ago

Well, maybe I was wrong...

bsumirak commented 9 years ago

Ok, the problem was solved by using *.class.getName() instead of plain class name as used in direct code. Apparently, the problem was that the name for nested types is not appended by a ".", but by a "$".

stephanmg commented 9 years ago

Okay.

@bsumirak can you commit your Code?

I see, it's in the VRL-Userdata project...
