Installed my own extension but can´t find it in operator tree

duken

Hello, 

I developed my first operator and installed it. IntelliJ shows me that that the build was successful and 
that the task "installExtension" is finished and i can see that the extension was loaded in the "About Installed Extensions" - menu. However I can not find my operator in the operator tree. Any suggestions what the reasons could be?

Best Regards

Hey @duken,
very hard to debug, because it can have quite a few reasons. Any chance you can share the code?

Otherwise, anything in the rapidminer-studio.log which looks odd?

Best,

Hey @duken,

That's weird, typically is should be a child of extensions folder in operator, did you try restarting Studio. Also checkout this thread https://community.rapidminer.com/discussion/56872/tutorial-for-creating-custom-operators/p1?new=1.

Hi @hbajpai, 

Thanks for your answer. 
yes I rebuilt and reinstalled it multiple times but it´s still not there. 
The weird thing is when I was doing the "Extension-Tutorial" I could find the empty operator in the tree.

Hey @mschmitz, 

thanks for your answer but I managed to get it to run now. 
The problem was an NullPointerException.
Checking the .log definitely helps.
