>I am encountering Similar problem as Michael is where my checkbox is grayed out when bound to a table. I looked at your suggestion of putting this.lEnabled in When() and was wondering do I make lEnabled into a Logical property first?

I'd use David's solution in the thread, setting the DisabledForeCOlor to rgb(0,0,1). As for my solution, yes, use a custom property called lEnabled instead of Enabled, then put the return this.lEnabled in the When().
