Matt --

The result is as you fear, I believe.

When you rename the property in your base form class and then go revisit a form based on that class, you'll see that that property (with the new name) shows up as default -- not the value that you had set it to.

And, curiously, if you then go back to the base form class and change the name back -- presto, the values you set in the sub-class re-appear! (Not that it does you any good).

If this is really important, you can do the following:

(1) Instead of re-naming your property in your base class, just create the new property.

(2) Then, copy the old property value to the new one, as follows (invoke this for each form)

Modify Form (oFile.Name) Nowait
FixPropertyName()
Activate Window 'Form'
Keyboard '{CTRL+w}'
DoEvents

Procedure FixPropertyName
     Local laObjects(1), loForm
     ASelObj(laAobjects,1)
     loForm = laAobjects(1)
     loForm.(newpropertyname) = loForm.(oldpropertyname)
endproc

(3) Delete your old property.

This might be more work than is worth it. On the other hand, it's a nice technique to have
