Unanswered: FormButtonBinding is there a replacement?
In the old GXT 2 days, I used FormButtonBinding a lot, to make my buttons enable and disable themselves depending on if a FormPanel was valid or invalid.
However I see that the class doesn't exist any more, and also a lot of examples have moved away from the FormPanel. That's all fine apart from two useful details: VerticalLayoutContainer does not have an isValid for fast and easy validation and the missing FormButtonBinding as previously mentioned.
I could create something similar myself, but then some questions occurs:
There must be a reason for moving away from FormPanel for the examples? Does it mean I shouldn't use it, unless I need to submit data to some non-GWT-service?
Is there a replacement for FormButtonBinding? If not there's probably a good reason for it's removal?
Is there a good way to achieve this functionality? Some method, class or similar I just don't find?
I mentioned today GWT-Pectin which seems well suited to this usage. I don't know how it overlaps with existing validation facilities of GXT3. Disclaimer: I haven't really used this library yet, I just find the demo quite convincing...
