Editable Data table in request scop JSF2.0

[Arvind Purohit]

Hi All I have list of module object. I want to show it to user and user can edit it and can save it also. In module object three members are there 1 String moduleName 2.boolean readFlag 3. writFlag.

The bean i am using is in Request Scop i don't want to use any other scop. My problem is setterOfThatList is not called when update button is clicked. Where as on the same page i used another inputText, setter of the variable which is connected to this inputText is called.

<h:dataTable value="#{roleBean.listMatrixDo}" var="list">
                <h:column>
                    <f:facet name="header">
                        <h:outputText value="Module Name"></h:outputText>
                    </f:facet>
                    <h:outputText value="#{list.moduleDo.moduleName}"></h:outputText>
                </h:column>
                <h:column>
                    <f:facet name="header">
                        <h:outputText value="Read Access"></h:outputText>
                    </f:facet>
                    <h:selectBooleanCheckbox value="#{list.readFlag}" />
                </h:column>
                <h:column>
                    <f:facet name="header">
                        <h:outputText value="Write Access"></h:outputText>
                    </f:facet>
                    <h:selectBooleanCheckbox value="#{list.writeFlag}" />
                </h:column>
            </h:dataTable>

What you want doesn't count. Sometimes life is cruel. Computers doubly so. If you use a dataTable, you need a tableModel that can survive over multiple requests. Otherwise, a new model will be created and destroyed on each request and the context won't be valid for you.

If you're using JSF2, you can use ViewScope and that will construct a short-term session object that will automatically be purged when you go to a different view. For JSF1, you have to use session scope.
