rich:graphValidator with value attribute doesn't prevent tab

[roeber]

I am using the rich:graphValidator with the value attribute. So there are some validations done for non input data fields. The validation itself works fine.
But in contradiction to some other validation (as the required attribute) a failed (graphValidator) validation doesn't prevent a rich:tab(panel) to switch to a different tab.
This means the error message is shown in the new active tab, which is confusing. And the invalid value is now stored in the model, which leads to other problems.

Any ideas?
Is there any work-around to properly prevent the tab switch in this situation?

Thx.

graphValidator value validation occurs after update model phase. There is no other option because we need all the model to be updated in order to check the whole bean. Thats why all the changes actually made in this case. So you should catch this situation by yourself and reset the tabPanel for example by using reseting selectedTab.

Thanks, I understand or better that's what I was already assuming. But what is a good place to reset the selectedTab? The valueChangeListener of the tabPanel?

As an idea for future releases: What do think of a special handler to check whether a tab switch is allowed?

No, this should happen after valueChangeListener is called, on the UPDATE_MODEL_VALUES phase.

Tabs are already validated, you can use "action" attribute of rich:tab to implement such behavior.
