ID 415305 - FarmAPI Menu commands do not work when chosen in Utils menu

Problem summary

Farm API menu options added via FarmAPI.AddFarmMenuOption() do not trigger their connected action when selected in the Utils menu.

Customer reported version
Katana 3.2v2

Steps to reproduce

1. In a KATANA_RESOURCES directory (for example the .katana folder in your home directory), create a Plugins subfolder if it doesn't already exist.
2. In the Plugins folder, create a FarmAPI.py file containing the following Python code:
   
   from Katana import FarmAPI

   


   def onStartup(**kwargs):

       # Add menu options

       FarmAPI.AddFarmMenuOption("Potato", _printPotato)

       FarmAPI.AddFarmPopupMenuOption("Potato", _printPotato)

   


   Callbacks.addCallback(Callbacks.Type.onStartup, onStartup)

   


   def _printPotato():

       print "Potato"
   

   
   
3. Launch Katana
4. In the main Katana menu, select Utils > Potato

Expected behaviour
The callback connected to the menu option should be triggered, printing "Potato" to the console.

Actual behaviour
The callback connected to the menu option is not triggered and nothing is printed to the console.

Workaround
Use the FarmAPI.AddFarmPopupMenuOption() function instead to add a menu option to Render nodes' context menu and select the option from there.
