Have tried to copy the Property example example to get a workspace plugin to work.
It seems identical in code but i noticed that when i select on my tab..i see an error…
SCViewAndLayoutItem: parent is null!. View is:Asset Of Things …i’m i missing something?
Does this happen with the unmodified Property sample, or have you copied code and now see the issue?
Can you give me a screen capture or something to get a better idea about the error?
here my code…
If you want to make a new plugin start with the template. “MIPPlugin” See MIP Documentation: Getting Started - Plug-in Development.
Your xxDefinition.cs will automatically be correct then.
I think this is what is wrong with your plugin.
Note. I cannot build your project and another time I think you should try to go with the questions instead of sending a full project. Hope you understand.
thanks Bo 
Will do as suggested
