GUI issue

[zedblade]

Hello,

 

I'm developing a mod with 2 objects (1 Item, 1 block) and 2 very similar GUI.

 

Now when i right-click on my block with my item in hand i open a GUI to save the position of the block into a tagCompound of my Item, and instead when i right-click with my item at any part i open another GUI totally similar to the previous GUI.

 

The GUIs have 1 Title, 1 textfield and 2 buttons (OK and Cancel), this is the code:

    {

        String var3 = (new String(var1)).trim();       

    }

}

 

 

 

In a new world i use all my objects without problems but when i esc and re-load my world MC goes to crash, randomly but most of the times, when i try to open a GUI with my Item in hand:
