Conditional validation not working

[Kevin-35]

Hi,

We need some advice on validation in Jahia, specifically conditional
validation of a Jahia container.

Validation seems to be done with Struts Validation rules. OK. I've
done that in systems of my own in the past.

We've been able to make validation work for simple rules in Jahia such
as "is a field required or not"
However, if we want to make a field required conditionally, we've run
into some strange problems.

It seems that if you use the "validwhen" argument, it works the first
time in that Jahia stops you and displays your validation message
(such as "x is required when y is foo").

But, if you put in the valid text and click OK it should pass
validation, create the record and close the Content Object window.
Instead, it reloads the pages and continues to display the validation
message.

Has anyone come across this? Has anyone tried to do conditional
validation of fields in Jahia?

Also notice below that the expression we are trying to validate is :
(docODS != 'Link')
In theory, it should be this (in our mind):
(docODS == 'Link')
However, we had to reverse it to get the expected validation message.
We don't know why.

Please help. This is very frustrating.

===========================
excerpted from our Struts validation XML file:
===========================
<form name="docBean">
    <field property="docName" depends="required">
        <arg0 key="label.doc.name"/>
    </field>
    <field property="docSymb" depends="required">
        <arg0 key="label.doc.symb"/>
    </field>
    <field property="docDate" depends="required">
        <arg0 key="label.date"/>
    </field>
    <field property="docLink" depends="validwhen">
        <arg0 key="label.doc.link"/>
                <var>
                        <var-name>test</var-name>
                        <var-value>(docODS != 'Link')</var-value>
                </var>
    </field>
</form>

</content:declareContainerList>

Thanks for any information you can provide.

Hi Kevin,

conditional validation with "validwhen" should work in Jahia. There is
only a bug for File field validations, which has been fixed in Jahia 5
SP4, but that seems not to be your current problem, although we
recommend you to consider switching to SP4 anyway ;-).

Your problem seems more to be the wrong usage of the validwhen
condition. I believe that you would like to make the "docLink" mandatory
only when "docODS" is set to 'Link', right?

With your condition:
<var-value>(docODS != 'Link')</var-value>

the docList entry will only be valid if the docODS is not 'Link', once
it is 'Link' it will never be valid regardless of being empty or not empty.

You need also to include *this* into your condition and rather use a
condition for docLink like this:

<var-value>((*this* != null) or (docODS != 'Link'))</var-value>

This means that validation of docLink will pass when docODS is not
'Link', but if it is 'Link' it will only pass when the current value for
'docLink' is set.

Hope this helps.

Regards,
Benjamin
