validation status has been added =]

reopened since I went back to the version that does not validate. I did not manage to handle all cases in time

postponed since this is not vital.

attached a patch, need intense checking.

Basically the problem here is that we validate on behalf of several properties:

• "create adapter" checkbox
• "available runtimes" items in the combo
• "selected runtime" selected combo item

To solve this with databinding we do not add validators to bindings. Validators in bindings are only able to validate single values (not composite properties). In databinding we add a MultiValidator to the DataBindingContext. The only tricky part is that you have to access all values, that take part in the the validation result, on behalf of observable values (and not in widgets/beans). The MultiValidator tracks behind the scene what observables are accessed and elaborates when he has to revalidate instead of returning a cached value. If your validator impl accesses the validation values in widgets (not observables), then the validator wont be called when the values, that participate in the validation, change.

committed patch to TRUNK (Beta1)

I also cleaned the layout a bit so that all actual widgets get left aligned below each other (and centered vertically if displayed in 1 row).

This is how it looks now:

I'm closing this JIRA as it is out of date. The behavior is different now.
