Validation with Class-level constraints on rowEditor?

[aroeber]

Hello,

is there a way to do JSF validation with class-level constraints (JSR303 or something comparable) on the datatable rowEditor component to do some business check on the whole bean?

I am already using Omnifaces o:validateBean and give JSF 2.3 a try with f:validateWholeBean. It is working on simple forms but seems to fail in a datatable with rowEditor - e. g. with the error message "f:validateWholeBean must be nested directly in an UIForm".

Using onRowEdit to do some business validation is possible but at the time of the event the JSF validation phase is over and (form) data is already accepted (rowEditor is showing the pencil instead of accept and cancel symbols).

Any ideas? Any experiences?

Best regards,
Axel
