I was trying to test the example module " oepetstore" of guide https://doc.odoo.com/trunk/training/web_framework/ writed
After installed it in my local test enviroment without any changes,I clicked menu "Pet Store", system showed an action error that was "
Could not find client action 'petstore.homepage'
".
I tried to fix this,but still could not find solution. Are there any other configurations need to be configed in the module? Thanks very much!
same problem here!
I have same issue in odoo 9 and 10
It is due to Old code. You need to change code with new API.
