how to reset the form?
Hi,
I am facing some problem while trying to reset the form.
I am using convertors and validators on the same form elements so I have enabled the "immediate" property of reset button to "true" to avoid the validation process, and in backing bean I am setting the field values but the new values are not getting reflefted in front view. As I can see there is no request made to get the new values from backing bean.
Here are the code snippets:
1. Front view - facelet
<ice:outputLabel value="${msgs['common_name']}"></ice:outputLabel>
<ice:panelGrid columns="2">
<ice:inputText style="width:500px"
value="${roleManagementController.id}" id="name"
partialSubmit="true" required="true"
requiredMessage="${msgs['validationerror_name'] }"
disabled="${!roleManagementController.addMode}" ></ice:inputText>
<ice:message for="name" style="color" style="color:ff0000" >
b. Reset button :
<ice:commandButton value="${msgs['reset']}"
actionListener="${actionController.reset}" style="margin-right:50px;margin-left:50px" immediate="true"/>
2. Backing bean -
a.
/**
* @param role
*/
public void reset(ActionEvent actionEvent) {
id = null; renderManager.getOnDemandRenderer(sessionId).reque stRender();
}
b.
public void setRenderManager(RenderManager renderManager) {
this.renderManager = renderManager;
renderManager.getOnDemandRenderer(sessionId).add(t his);
}
public PersistentFacesState getState() {
System.out.println("RoleManagementController.getSt ate()");
return persistentFacesState;
}
public void renderingException(RenderingException arg0) {
System.out.println("RoleManagementController.rende ringException()");
// TODO Auto-generated method stub
}
3. Web.xml
<servlet>

4. Server.xml file of Tomcat 6.0
<Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtoc ol"
connectionTimeout="20000"
redirectPort="8443" />
I tried to use Ajax push to forcefully update the front view values but I am getting this error:

do you have any idea how to configure the web.xml and the server.xml in tomcat6.o.
I know one way to rest the form and that is, to have binding for all the form fileds and call the submittevValue of UIComponent in reset method on backing bean, but my form contains a lot of fields so I want to avoid doing form reset in that way.
It will be helpful if you guys can suggest me any other way to reset the form.
Thanks in advance.
Regards,
Vinay.
