a4j:support and immediate for the parent component

r_sudh Apr 8, 2009 2:56 PM

<t:inputText id="company" label="Company" value="#{action.company}" required="true"/>

<t:inputText id="code" label="Code" value="#{action.code}">
 <a4j:support action="#{action.refreshFromCode}"
 event="onkeyup"
 reRender="namePanel/>
</t:inputText>

When the company input box is empty and I trigger the a4j action, the JSF lifecycle skips to the render response from the process validation phase. I guess this is because the required field validation on the company fails.

If I set immediate=true on the a4j:support tag the call to the refreshFormCode method works. But the value I get for the Code attribute is from the previous request. Looks like immediate=true on the a4j tag skips the Apply Request Value for the Code inputText component.

How can I get the effect of immediate=true but still get the current value entered in the Code input text?

Thanks in advance for any help.

Thanks! That did the trick. Here's the solution.

<t:inputText id="company" label="Company" value="#{action.company}" required="true"/>

<a4j:region>
 <t:inputText id="code" label="Code" value="#{action.code}">
 <a4j:support action="#{action.refreshFromCode}"
 event="onkeyup"
 reRender="namePanel
 ajaxSingle="true"/>
 </t:inputText>
</a4j:region>
