Hello,

wenn i add constraint="No Empty" on for example an Textboxt, an validation error is a tooltip on the browser.

I have a save-Button an react on it on Java-Side. Is there an easy way to put an error on the Text from out of my Java-Code?

Thanks in advice for giving me a suggestion.

Hi,

i'm not sure about your issue, do want fire errormessages from your javacode.

Variant 1:
This could be done with:

throw new WrongValueException(comp, errMessage);

in your javacode.

comp = Component i.e. Textbox
errMessage = String with the errormessage

Variant 2:
Is write custom contraints, that can more than no empty. Check this docs.
