definition Default Value

Just completed a snippet which changes the Default Value of some Definitions.

I used the function ACAPI_Property_ChangePropertyDefinition, however, that function failed. i seems it has to be wrapped in a undoable callback. ACAPI_callUndoableCommand.

As i look at the other examples in Property_Test none of the other functions need this call back, even to change the definition name.

Wondering why this particular restriction is necessary and is there any work around if I don't need to undo?

I took a quick look and it appeared that all the property tests are called from within APIMenuCommandProc_Main, which embeds all these tests in ACAPI_CallUndoableCommand
