[SOLVED][MC 1.7.2]Crash on EntityPlayer.openGui()

[ruabmbua]

Hello Guys!

 

I got an NullPointerException on opening my custom gui. I already debugged my mod in eclipse, and what I found out is, that the Exception was thrown from NetworkRegistry.getLocalGuiContainer(). Further I realised, that my ModContainer is null. Can it be an internal error?

 

Exception:

java.lang.NullPointerException

I hope someone can help me.

I inserted the instance of my mod.

 

I mean the @Instance field in my main mod file.

This is my main file: https://gist.github.com/ruabmbua/7745982aabb8b6ebe00b

And this is the openGui calling method in my block: https://gist.github.com/ruabmbua/c0b2ad93d96162b6be70

Your mod id and instance names don't match:

 

public static final String MODID = "ruabmmod";

@Instance("RuabmMod")

 

Use the modid for your instance name.

Thanks i did not looked at that.

I hope this is the complete solution. I will try it, if I am back home.
