[ExtVal] Validations for one action only

[Cédric Durmont <cd...@gmail.com>]

Hello there,

I'm trying to implement a somewhat classical validation scheme : I
have a JSF form ( Myfaces 2.1.5, Trinidad 2.0.2-SNAPSHOT), and I want
to perform some validations but only when I trigger a specific button
/ action.
Other buttons in the page may open dialogs, trigger actionEvents /
valueChangeEvents. There are also some autosubmit input fields
(Trinidad), and I need all these to run without being stopped by the
validation.

I tried to simply use immediate="true" on every button / field where
it was needed, but strangely enough, it didn't stop all of the
validations (esp. the input fields with autosubmit + immediate="true"
act as if they were immediate="false".

Can some folks here give me a hint on the best way to achieve this ?
My validations a a mix on static (this field is numeric, this one's 50
chrs max, etc.) and dynamic ("if value of attribute A is in a specific
list, then B becomes mandatory", "X or Y may be null, but not both")
Getting these to work with Trinidad's client-based validations would
definitely be the icing on the cake !

Thanks,

Cedric Durmont

hi cedric,

you can have a look at [1].

@client-side validation:
you can use component initialization to get the corresponding
information to the browser.
