[Laszlo-user] Simple binding breaks in

[Yang]

I'm using LPS4.0.2 and I have a simple binding between a
checkbox.value and a button.enabled. As soon as I put this in a
window, it breaks:

 <window name="control" width="150"
         allowdrag="false" resizable="false" title="Control">
   <simplelayout axis="y"/>
   <checkbox name="autoSuggest" width="100%" text="Auto-suggest"/>
   <button text="Suggest" width="100%" enabled="${!autoSuggest.value}"/>
 </window>

I get the following Debug errors:

ERROR: copy-of-hello.lzx:21: reference to undefined variable 'autoSuggest'
ERROR: copy-of-hello.lzx:21: undefined object does not have a property 'value'
WARNING: copy-of-hello.lzx:21: reference to undefined property 'value'

Thanks in advance for any hints.
