    Rerender HTMLInputText in datatable (richfaces-art-datatable

    Tim Stuck Newbie

      Hi all,
      (see http://jboss.com/index.html?module=bb&op=viewtopic&t=105668&postdays=0&postorder=asc&start=0 )

      Sergey, I have seen your example on richfaces-art-datatable on how to reRender a column in a datatable
      http://labs.jboss.com/wiki/RichFacesArticleDataTable

      I am working with Kristein and we are probably the reason why you created this example. I am able to get our code working, i.e. correctly reRendering a column in a dataTable, but only when reRendering an HTMLOutputText component like your example does.

      In our case we need to allow the user to enter either a ProposedPrice or a ProposedGrossMargin. Whenever the user enters a ProposedGrossMargin, the app should calculate a ProposedPrice based on that grossMargin and vice versa. Thus, both have to be HTMLInputText components.

      And therein lies our problem. If the user changes the ProposedPrice the ProposedGrossMargin doesn't get reRendered. Debugging the app shows that, indeed the DTOs are being updated correctly with the correct values, but the corresponding column is not reRendered.

      Can you expand your example to attempt to reRender an HTMLInputText?

      Here is a code snippet of the JSP:

       <rich:dataTable value="#{PriceModelHeaderBean.listDataModel}" var="item"
       first="#{PriceModelHeaderBean.currentRowIndex}"
       rows="#{PriceModelHeaderBean.rowsPerPage}"
       styleClass="partDataTable" rowClasses="rowLight, rowDark" headerClass="dataHeader"
       border="0" cellspacing="0">
      
      .
      .
      .
       <h:column>
       <f:facet name="header">
       <h:commandLink action="#{PriceModelHeaderBean.sort}"
       actionListener="#{PriceModelHeaderBean.bindSortColumn}"
       value="Proposed Price" immediate="false">
       <f:attribute name="sortColumn" value="dto.proposedPrice"/>
       </h:commandLink>
       </f:facet>
       <a4j:outputPanel>
       <h:inputText id="price" binding="#{PriceModelHeaderBean.proposedPriceRef}" value="#{item.dto.proposedPrice}">
       <a4j:support immediate="true" action="#{PriceModelHeaderBean.changePrice}" event="onchange" reRender="grossMargin"/>
       </h:inputText>
       <h:message for="price" />
       </a4j:outputPanel>
       </h:column>
      
       <h:column>
       <f:facet name="header">
       <h:commandLink action="#{PriceModelHeaderBean.sort}"
       actionListener="#{PriceModelHeaderBean.bindSortColumn}"
       value="Proposed GM%" immediate="false">
       <f:attribute name="sortColumn" value="dto.proposedGrossMargin"/>
       </h:commandLink>
       </f:facet>
       <a4j:outputPanel>
       <h:inputText id="grossMargin" binding="#{PriceModelHeaderBean.proposedGMRef}" value="#{item.dto.proposedGrossMargin}" >
       <a4j:support immediate="true" action="#{PriceModelHeaderBean.changeGrossMargin}" event="onchange" reRender="price"/>
       </h:inputText>
       <h:message for="grossMargin" />
       </a4j:outputPanel>
       </h:column>
      .
      .
      .
       </rich:dataTable>
      .
      .
      .
       <a4j:outputPanel id="err" ajaxRendered="true">
       <h:messages />
       </a4j:outputPanel>
      


      Thanks for your help!

          Could you please check with a4j:log what problems appears on client while reRendering..?

              Sergey Smirnov Master

              Thank you Willy that you explained why you need two input fields calculated from each other.

              Having this combination (two input fields that cross updated via model) you will have a trouble even without Ajax and even without table at all. This is known JSF problem when the input field does not take the value from the model while the view is not changed.

              I see you use binding already. So, you can replace the value in the component tree directly rather than expect the value taken from model.

                Hmm... thanks, Sergey. I didn't know this was a known problem w/JSF. So, for clarification, are you saying that if I manually replace the value in the component (in my changePrice() action method) it will show up on the HTMLInputText field? Or is there really no way to force the Input field to reRender? Do I have to actually refresh the page (Ajax aside) in order to refresh the Input field value?
