In that case, yes.
Because wo will try to assign all the bindings :
<wo:TextFieldCalendar date = "$maxBidClosingDate" default = "Bid
Closing Before"/>
setDate(...);
setDefault(...); .... oops doesn't work !
So yes you do not want to sync the bindings if you can't do
'setDefault()'
But you could still sync the bindings, have an empty 'setDefault'
implementation. And the caret would work, it's equivalent to the
'super' prefix of java method call, but for bindings.

So caret notation only works if you're not synchronizing bindings?

Hi all,
I've always thought that using caret notation was a good idea
when creating reuseable components, but it only seems to work for
me about half the time, so I'm not sure I fully understand it.
I have a component that has a textfield whose "default" binding
should be inherited from it's parent component bindings:
<wo:textfield value = "$date" id = "$id" size="~format.length()"
dateformat = "$format" default="^default"/>
This textfield is embedded within a component named
TextFieldCalendar. Here's my usage of TextFieldCalendar in
another component:
<wo:TextFieldCalendar date = "$maxBidClosingDate" default = "Bid
Closing Before"/>
When I run the application, I get the following exception:

I thought that the point of using caret notation was that you
didn't have to declare a local variable called "default" in the
reuseable component. Am I off track here? Has anyone else
noticed this behavior?
Thanks,
Mark
