If there is an issue regarding the implementation of the UI in the view class, the node should still be shown in the Structure Tab.
To get a better picture what is going on, could you please provide further information on the different parts of your URCap?
the URCaps is an update of an URCaps based on html so for now I only want to create a program node with two combo box,
The differents class to create the node contains only necessary method plus some methods to create the combo box and get/set their values.
The problem is that all my other URCaps are correctly installed but this one just doesn’t appear in the structure tab, if you want the code for all classes :
Activator class :
It seems that the first argument for the registration of the program node is wrong in the activator class.
Here it should state: bundleContext.registerService(SwingProgramNodeService.class, new Robo...(), null);
