Subject: Re: Struts Validation - Stop on fail?

Hello,
Padma Ginnaram replied to me directly (thanks!) so here is the message in
case someone was having a similar problem:
--- From Padma's message
[...]
If a validator depends on other validators, it is not invoked unless all the
dependencies are successful. Your float validator might be dependent on
required which could cause the behavior you are seeing. You can remove this
dependency if you don't want this behavior.
This functionality is useful if you donot want to run a validator like
'daterange' unless date validator is successful.
[...]
--- End
FYI, the "depends" information is in the validator-rules.xml file ('depends'
validator attribute). If you want to change this behaviour so that the
validations are called even if the dependent fails, remove the attribute.
This implies that you must add "required" as a field validation (in
validation.xml) to make sure that you don't try to validate as a float an
empty String (which would fail).
HTH. Thanks again to Padma for his reply.
