jsf - Editable dataTable with inputText -


i want add inputtext datatable. inputtext used add new user (name, role, age) , save database. can olso update existing values in datatable. example let's have datatable.

enter image description here

what dynamically add inputtext fields first row of table on button click. fill in values insert , click on save button.

the idea come add editable="true" datatable , use <p:celleditor> , <p:roweditor/> this:

<p:datatable var="item" value="#{usercontroler.users}" editable="true">      <p:column>         <p:celleditor>             <f:facet name="output">                 <h:outputtext value="#{item.name}"/>            </f:facet>            <f:facet name="input">                 <p:inputtext value="#{item.name}" style="width:100%"/>            </f:facet>         </p:celleditor>     </p:column>     <p:column>        <p:roweditor  />     </p:column> </p:datatable>

and add new epmty user list, refresh datatable, edit new user , save on event rowedit. there way this?

because problem face due composite-id. when enter new value can't know if i'm going update or save given value. (suppose composite-id name , role. if want insert new value , make mistake , insert existing value i'm going have update instead of error message).

hope i'm clear enough. if not can provide more information.thank you.

i did balusc suggested.

<p:datatable var="item" value="#{usercontroler.users}" editable="true">      <p:column>         <p:celleditor>             <f:facet name="output">                 <h:outputtext value="#{item.name}"/>            </f:facet>            <f:facet name="input">                 <p:inputtext value="#{item.name}" style="width:100%"/>            </f:facet>         </p:celleditor>            <f:facet name="footer">               <p:inputtext value="#{usercontroler.newuser.name}" />            </f:facet>     </p:column>     <p:column>        <p:roweditor />        <f:facet name="footer"><p:commandbutton action="#{usercontroler.add}"/></f:facet>     </p:column> </p:datatable>

works fine.
