[Laszlo-dev] Value binding in combobox

[P T Withington]

By default, the value of an item is an expression and will be evaluated.

You need to say value="'Hello'" so the value is the string 'Hello'  
rather than the undefined variable Hello.

Or, you need to say:

   <textlistitem ... type="string" value="Hello" />

If you compile swf8 or DHTML with debugging and test, you should get a  
warning about an undefined variable.  The swf9 compiler is more  
sophisticated and can give you the warning at compile time.  We also  
recommend testing DHTML in Firefox with the Firebug debugging add-on,  
or in Safari with the Develop menu and Javascript debugging enabled.  
Either of these debuggers will help you to spot errors in DHTML code  
when the OpenLaszlo debugger is not enabled.
