hi,
I am trying to introduce a validation rule that checks that at least one
element has been
added to an optiontransferselect UI component. I use the expression type
validation but
does not seem to work ... see the details below.
<field name="outSamplePeriods">
<field-validator type="fieldexpression">
<param name="expression"><![CDATA[ (outSamplePeriods.length > 0)
]]></param>
<message><![CDATA[ At least one Out of Sample Period must be
provided ]]></message>
</field-validator>
</field>
TIA,
regards,
Giovanni
