Hi Robin,
AFAIK widgets are validated in two cases :
- When getValue is explictly called
- When validate is called
This means that in a normal form usage, they are validated :
- If another component (say, an event listener) calls the getValue() for
some reason.
- If a submit button is pressed (explicit call to validate() )
- If an action button with validate = true is pressed (explicit call to
validate() )
The "http submit" that happens with submit-on-change="true" or with an
event handler, with or without ajax, is not a "cform submit", so doesn't
trigger validation if not as a side effect of something else going on.
You could try calling validate() explicitly from inside your event
handler, it could work but i've never tested it, so let me know :)
Regards,
Simone

Hi All,
I have a text field with custom validation and a value-on-changed
event listener...
<fd:field id="video_key" required="true">
<fd:datatype base="string" />
<fd:validation>
<fd:javascript>
return validateVideoKey(widget);
</fd:javascript>
</fd:validation>
<fd:on-value-changed>
<fd:javascript>
updateFiles(event.source);
</fd:javascript>
</fd:on-value-changed>
</fd:field>
When the value of the field changes, the custom validation is
executed and if successful then my value-on-changed listener is
executed also - all good. If the validation fails then my value-on-
changed listener is not executed, which is (I think) also the
expected behaviour.
However, when the validation fails as a result of the value-on-
changed listener being fired no validation error message is show on
the form. My custom validation sets a ValidationError on the widget,
and this gets displayed if the form is submitted with a submit
button, just not when submitted as a result of the value-on-changed.
This is true with both AJAX enabled or AJAX disabled on my form.
Is there a way I can get the widget to display its ValidationError
after being validated as the result of the value-on-changed?
Alternatively, and in my particular case this is preferable, is there
a way I can disable the validation before the value-on-changed on
this field?
Thanks,
Robin
