[Databinding] Not validate a form when it is first opened [message #333919]

Hi,

There is a way to not validate a form at the first time it is opened?

The same behaviour as the plugin.xml edit form.

I am using the MessageManager integration.

Thanks,

Marcelo

See the code for DialogPageSupport to see how DataBinding does this
internally. (short version: don't show an error or cancel status
message until after a change event is fired from one of the target
observables of a binding in a DataBindingContext)

Could you point me to the relevant classes having to do with
MessageManager? I'm not sure what integration component you're talking
about.

Hi Matthew,

I verified your DialogPageSupport and verified the TitleAreaDialogSupport
also. But could not integrate them well with my code here.

I am posting the class I was having the problem. This class just have one
field, very simple. It returns to the caller null if cancel or dialog close
is pressed, or the filled string.

Could you please take a look? I used the message manager integration found
in bug 219661.

Thanks!

Marcelo
