CustomKeys behavior

[Ken Ray]

Tariel,

I believe your problem stems from not quoting 'tbRowData'. Left unquoted, it
can be interpreted as a variable or as a string. What determines this is if
the variable is used anywhere in the handler that is being executed. When
you only have:

> on mouseup
>   set the customkeys[tbRowData] of grp "Table" to empty
> end  mouseup

... 'tbRowData' is not used anywhere else in the handler, so Rev interprets
it as the string "tbRowData". However, in your button 'c':

> on mouseup
>   set the customkeys[tbRowData] of grp "Table" to empty
>   set the tbRowData["MyProperty"] of grp "table"  to SomeRowData
> end  mouseup

... 'tbRowData' is used as an array and so Rev tries to interpret it as a
variable and fails to work. I'd recommend trying:

on mouseup
  set the customkeys["tbRowData"] of grp "Table" to empty
  set the tbRowData["MyProperty"] of grp "table"  to SomeRowData
end  mouseup
