a4j:ajax , revert datamodel changes

[stamar]

Hi all;

  I have a module in my application for user administration. When administrator changes the role of the person (in a popup window), other fields must be rendered .... see the piece of code below:

                             <h:panelGroup layout="block" styleClass="sie-field">

                                <h:panelGroup styleClass="popup-row">

                                    <cc:outputLabel forId="entry-role" colon="true" required="true" value="#{msgs.user_Role}" />

                                </h:panelGroup>

                                <h:panelGroup>

                                    <rich:select id="entry-role" value="#{administrationBean.person.role}" required="true">

                                        <a4j:ajax render="entry-substituteActive,entry-substitute,entry-substitute-label,entry-auditor,entry-auditor-label" execute="@this" event="selectitem" />

                                        <f:selectItems value="#{administrationBean.dataService.roles}" var="item" itemValue="#{item}" itemLabel="#{item.name}" />

                                        <rich:validator />

                                    </rich:select>

                                    <rich:message for="entry-role" />

                                </h:panelGroup>

                            </h:panelGroup>

I have a problem, when administrator edits the person info....so e.g. edited person has set 'role1'. The administrator changes this role to 'role2' (a4j:ajax changes my data model) and he press cancel button. In the model stays value role2 ... and that is the problem.

my cancel button looks as follows:

                           <a4j:commandButton id="abort-popup" value="#{msgs.buttonAbort}" action="#{applicationBean.refreshView}" immediate="true" oncomplete="#{rich:component('person-popup')}.hide();" />

refreshView method:

public void refreshView() {

        FacesContext context = FacesContext.getCurrentInstance();

        Application application = context.getApplication();

        ViewHandler viewHandler = application.getViewHandler();

        UIViewRoot viewRoot = viewHandler.createView(context, context.getViewRoot().getViewId());

        context.setViewRoot(viewRoot);

        context.renderResponse();

    }

This method refreshes everything except the values that were changed by a4j:ajax

Has anyone idea, how to solve it?

Thanks a lot

I solved already the problem.

- in the administrationBean I created private variable originalRole and the setter.

- I also created method refreshView in this administrationBean (because the one from applicationBean was generally used on many places in my app) and added row

     person.setRole(originalRole);

at the end of the method

- to the edit-commandLink (on the jsf page) I added setPropertyActionListener

<f:setPropertyActionListener target="#{administrationBean.originalRole}" value="#{person.role}" />

I hope it helps somebody
