Paging a data table with input text fields

Question

I've created a datatable with input text fields so that contents can be edited. I have 'save' and 'cancel' buttons on the page so that changes can be saved or abandoned. That seems to work fine.
However, I have a problem with paging. If I modify an input text field, page to the next page in the datatable and then page back, the modified input text field reverts to the original entry in the database. Does anyone know how I can preserve this change (without issuing a commit) until the user clicks on the save button?
Here is a snippet of jsp with datatable.
<h:dataTable binding="#{DocTypeDetail.doctypeMetadataTable}" headerClass="list-header" id="doctypeMetadataTable"
rowClasses="list-row-even,list-row-odd" rows="5" style="left: 240px; top: 312px; position: absolute"
value="#{DocTypeDetail.doctypeMetadataTableModel}" var="currentRow">
<h:column binding="#{DocTypeDetail.column2}" id="column2">
<h:inputText binding="#{DocTypeDetail.textField1}" id="textField1" value="#{currentRow['name']}"/>
<f:facet name="header">
<h:outputText binding="#{DocTypeDetail.outputText5}" id="outputText5" value="Name"/>
</f:facet>
</h:column>
<h:column binding="#{DocTypeDetail.column3}" id="column3">
<h:inputText binding="#{DocTypeDetail.textField2}" id="textField2" value="#{currentRow['value']}"/>
<f:facet name="header">
<h:outputText binding="#{DocTypeDetail.outputText8}" id="outputText8" value="Value"/>
</f:facet>

</h:panelGroup>
</f:facet>
</h:dataTable>

I know by now you must have figured it out. If not you might want to try keeping the backing bean in session instead of request scope.
Hope that helps,
