failure to resolve method when used in tag files
Hi,
I'm trying to use ajax4jsf from a tag file. When I issue a click on a link whose action is a method, the server logs the error "Target Unreachable, identifier 'value' resolved to null" causing "internal server error" message box on the browser.
I'm using glassfish-9.0 (b48) with JSF-1.2_03, but I don't think it is a JSF related issue, normal JSF commands work well from tag.
I'm digging into this for several days and cannot figure what is hapenning...
Here is the tag I'm using:
<%@ tag display-name="t" isELIgnored="false" body-content="empty"%>
<%@ attribute name="value" required="true" deferredValue="true" deferredValueType="samples.Bean"%>
<%@ taglib prefix="a" uri="https://ajax4jsf.dev.java.net/ajax"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<f:subview id="t">
<h:panelGrid id="grid" columns="8" border="1" columnClasses="display">
<h:outputText value="#{value.value}" />
<h:outputText value="#{value.editable ? 'T' : 'F'}" />
<h:commandButton value="TE" action="#{value.toggleEdit}" />
<a:commandLink value="FF" action="#{value.toggleEdit}" reRender="grid" ajaxSingle="false" immediate="false" />
<a:commandLink value="FT" action="#{value.toggleEdit}" reRender="grid" ajaxSingle="false" immediate="true" />
<a:commandLink value="TF" action="#{value.toggleEdit}" reRender="grid" ajaxSingle="true" immediate="false" />
<a:commandLink value="TT" action="#{value.toggleEdit}" reRender="grid" ajaxSingle="true" immediate="true" />
</h:panelGrid>
</f:subview>
Here is the tag invocation:
<a:form>
<q:t value="#{b1}"/>
<q:t value="#{b2}"/>
</a:form>
... and here is the bean
package samples;
import java.util.Formatter;
import java.util.logging.Logger;
@SuppressWarnings( "nls" )
public class Bean
{
private final String id = IdGen.next();
private boolean editable;
private String value = "this is my value...";
public Bean()
{
}
public Bean( String value )
{
setValue( value );
}
static Bean valueOf( String value )
{
return new Bean( value );
}
public String getId()
{
return id;
}
public boolean isEditable()
{
return editable;
}
public void setEditable( boolean editable )
{
this.editable = editable;
}
public String getValue()
{
return this.value;
}
public void setValue( String value )
{
this.value = value;
}
@Override
public String toString()
{
return getId() + ": " + getValue();
}
public String toggleEdit()
{
setEditable( !isEditable() );
return null;
}
}
Thanks for any help...
