I have changed the GUI handler code and it works now. however, when I place an item into the input slot, the getPowerRequirement function in the recipes class (attached below) crashes with a null pointer exception on line 81. I tried adding a try-finally statement, but that didn't help at all. any suggestions? https://gist.github.com/anonymous/7396246

I'm in the middle of a big modding project, and my chemical extractor is having some weird issues. There is no actual 'error' in the code, however it still doesnt work correctly. Symptoms: I put any item in the slot and it doubles Left click to remove and the item disappears right click divides stack in slot by 4 and the rest disappears does not process the item at all. I based the code of the vanilla furnace, but changed it to use an electrical supply which I am yet to implement. To 'charge' the block I change the value in the eclipse editor, but it still doesnt function. Any help would be appreciated. The files https://gist.github.com/anonymous/7366482
