The current version I'm working with is minecraft 1.5.2 and MinecraftForge v7.8.0.725, now yeah i know taht's not the latest version of forge but don't think that's the problem in this case.
Now the mod works fine, until you open up the gui for the crafting tables we have in simcraft, no they are based on the minecraft double chest code, but it's used for a crafting table, this worked like a charm from minecraft version 1.2.5 up until now.
What's happening now is in eclipse it works and theirs no error so all is good to go, I recompile the mod reob it and setup a 1.5.2 instance of minecraft with same version of forge used in eclipse, but it keeps crashin on the opening of the gui after it's recompiled.
So the question is does anybody have any idea where to look for the problem, I mean it's virtually working in eclipse, but not after being recompiled it doesn't make sense and being a semi noob I don't really know where to look or how to fix something that's already working inside eclipse any suggestion would be appreciated.
