Temporarily disable JSF validations
(1 answer)
Closed 6 years ago.
I have two panelgrids in my page.
In the first panel grid I have two input text with a button. This
button should valid only this input text.
In the second panelgrid i have 3 input text with a button which
should validate these 3 text only.
How can I ensure that on button click in thr first panelgrid , the
required=true gets ignored for all elements in the second panel grid.
Any help would be appreciated.

If you are using Primefaces you can use partial submit.
For your example:
<h:form>
<p:panelGrid id="grid1">
<p:inputText required="true" id="inp1" value="#{test.value1}"/>
<p:inputText required="true" id="inp2" value="#{test.value2}"/>
<p:commandButton partialSubmit="true" process="#this inp1 inp2" action="#{test.someAction()}" value="validation" update="grid1"/>
</p:panelGrid>
<p:panelGrid id="grid2">
<p:inputText required="true" id="inp3" value="#{test.value3}"/>
<p:inputText required="true" id="inp4" value="#{test.value4}"/>
<p:inputText required="true" id="inp5" value="#{test.value5}"/>
<p:commandButton partialSubmit="true" process="#this inp3 inp4 inp5" action="#{test.someAction()}" value="validation" update="grid2"/>
</p:panelGrid>
</h:form>
Or you can palce grids with buttons in separate forms. Beacuse by default ajax request posts (and validates) values only from current form.
<h:form>
<p:panelGrid id="grid1">
<p:inputText required="true" id="inp1" value="#{test.value1}"/>
<p:inputText required="true" id="inp2" value="#{test.value2}"/>
<p:commandButton action="#{test.someAction()}" value="validation" update="#form"/>
</p:panelGrid>
</h:form>
<h:form>
<p:panelGrid>
<p:inputText required="true" id="inp3" value="#{test.value3}"/>
<p:inputText required="true" id="inp4" value="#{test.value4}"/>
<p:inputText required="true" id="inp5" value="#{test.value5}"/>
<p:commandButton action="#{test.someAction()}" value="validation" update="#form"/>
</p:panelGrid>
</h:form>
