RE: Extending Textfield Question

Thanks for the info.  I will look at the InheritInformalAny component as
well.  Earlier in this email thread, Howard had suggested an enhancement
request.  I will add the enhancement request soon.
 
Thanks again...
Dorothy

Hi Dorothy,
 
Some time ago I suggested to have the ablity to inherit informal parameters
with precisely this use case in mind. It can be implemented with something
like the inherited-binding component parameter, but that inherits all
informal parameters instead. We have faced the need for such a functionality
as well.
 
I think that with the major new extensions in 2.4 the smaller proposals have
been put a bit on a back-burner for a while (as it can be expected). In any
case, I will add this to the list of developer issues on the Wiki. Given the
DTD changes in 2.4, it may be a good idea to add such modifications in that
release as well, but that has to be voted by the contributors first.
 
Btw, if you look at the InheritInformalAny component in Contrib, it offers
precisely that service for the Any component (it renders the parent's
informal parameters as well -- heavily used in Table). Should the above
feature be available, such a component will not be necessary.
 
Best regards,
-mb

Initially, I thought of the same approach.  However, how do you pass the
informal parameters into your contained Submit button?

Thanks...

OK - I see now.  We have the same problem - mainly with submit buttons.  We 
just created a FooSubmit component that uses (rather than inherits) a submit

component.  We can then control the default class from the FooSubmit, and 
let it be overriden on a case-by-case basis.  It's then just a matter of 
making sure everyone uses FooSubmit, rather than Submit...

PS. Some names were changed in the above to protect the innocent ;-)
