rich:findComponent and required not working

[hwoarang]

Hi there!

I'm trying to make an h:inputText required only if another one is not empty, but or I'm doing it in the wrong way or... dont know.

The snipppet:

<r:columnGroup>
    <r:column styleClass="noBorders">
        <h:inputText
            id="field1"
            size="7"
            disabled="#{MyBean.isExclusao}"
            value="#{MyBean.object.field1}" />
    </r:column>
    <r:column styleClass="noBorders">
        <h:inputText
            id="field2"
            size="2"
            required="#{not empty r:findComponent('field1').value}"
            requiredMessage="Informe o ramal"
            disabled="#{MyBean.isExclusao}"
            value="#{MyBean.object.field2}" />
    </r:column>
</r:columnGroup>

I tried the other form:

required="#{not empty r:findComponent('field1').attributes['value']}"

but didn't work too.

Please, someone has any idea why this do not work? Or some idea how to achieve my goal?

Please?

Thank you in advance!

Hello Flávio!

Can you try this?

{code:xml}

<r:columnGroup>
    <r:column styleClass="noBorders">
        <h:inputText
            id="field1"
            size="7"
            disabled="#{MyBean.isExclusao}"
            value="#{MyBean.object.field1}">
            <a4j:support event="onkeyup" reRender="field2"/>
        </h:inputText>
    </r:column>
    <r:column styleClass="noBorders">
        <h:inputText
            id="field2"
            size="2"
            required="#{not empty r:findComponent('field1').value}"
            requiredMessage="Informe o ramal"
            disabled="#{MyBean.isExclusao}"
            value="#{MyBean.object.field2}" />
    </r:column>
</r:columnGroup>

{code}

A post preview would be very nice!
