"[SOLVED]My new Extension is simply white In GUI!"
Hi forum,
I am about to write my own extension for RM according to the fantastic tutorial document of "How to extend RM 5.0". As the first step, I added the tutorial project ("Rapidminer_Extension_Tutorial") to eclipse and build the ant file. Every thing works fine and I can see the operator when I lunch RM. But when I add the operator to GUI, it's color is simply white! and I get "NULL Pointer Exception" when run a process including the new operator. What is wrong with my operator? Any help would be appreciated.
Thanks in advance.
