TTMSFNCObjectInspector Edit Mode?

I dropped the component on a FMX form, added some nodes with values.

Now I want the end user to edit the values in the value column, but whatever I try, I cant get it to allow editing. Is there any trick to do that?

the TTMSFNCObjectInspector is automatically creating nodes based on the properties it detects of the assigned Object. Please use TMSFNCObjectInspector.&Object := MyObject to list the properties that can be edited.
