[FLOW3-general] Validation and flashMessages

[David Sporer]

Hi Rens,

I don't think that this is his problem.
FLOW3/Flow is printing a default error message like "An error occurred while
trying to call..." and the only way to get rid of this I (and Rudy) know is
to override the getErrorFlashMessage method.

Means we know how to output the validation results but more than we want is
shown.

Regards
David

Hey Rudy,

When the validation on the arguments fails you are actually redirected to
the original action. This is working in Extbase like it is in Flow.

If you want to display the validation results of the form I would suggest
using the validationResults viewhelper for that:
http://docs.typo3.org/flow/TYPO3FlowDocumentation/TheDefinitiveGuide/PartV/F
luidViewHelperReference.html#f-form-validationresults

Hope this helps

Greetz,
Rens
