    Reload required...

    Razia Bhayani Newbie

      Hi,


      If someone could please guide me with this issue?


      I am having a strange issue with seam. I have this '.xhtml' page, on which I have multiple rows of data getting populated. I have provided a button Delete next to each row. Now, when I click this button to delete the row, all goes well if I descend from top to bottom or if I delete and intermediate row. However when I try to delete the last row, all my entries disappear and I have to reload the page to see all my entries. They don't get deleted in one shot but they disappear and the page goes blank unless I refresh it.


      Why does this happen?


      Please keep advised.


      Thanks,
      Raziya

          Show code and setup.

            BTW, are you binding the table itself to a backing bean component and/or using immediate?

                Yes I am binding Stateful bean as a backing bean of JSF

                  Could you post the backing bean also?

                      The issue remains even if you have no subview?

                        Haven't tried that yet...do you suggest to try that?

                          Doesn't hurt trying. Just guessing here...

                              Hey Nicklas,

                              It's amusing...Its working...
                              What's the issue with <f:subview>? Do you have any justifications?

                              Thanks alot for your support.

                              regards,

                                None whatsoever, just tried to isolate the problem. I've never used subviews, I usually stick to the rendered attribute on table itself or use some combination of s:div + rendered or ui:include

                                  Ok...

                                  There's another issue that I face. I have few recorded messages. I try to play them when someone presses a play button, and I give them an option to delete that message too.

                                  <h:dataTable value="#{uservoicemessages}" var="phone">
                                          <h:column>
                                          <f:facet name="header">Read</f:facet>
                                          <h:outputText value="#{phone.read}"></h:outputText>
                                          </h:column>
                                          <h:column>
                                          <f:facet name="header">From</f:facet>
                                          <h:outputText value="#{phone.phoneAddress}"></h:outputText>
                                          </h:column>
                                          <h:column>
                                          <f:facet name="header">Date</f:facet>
                                          <h:outputText value="#{phone.dateAddedOn}"></h:outputText>
                                          </h:column>
                                          <h:column>
                                          <s:button value="Delete" action="#{showuservoicemessage.delete}" />
                                          </h:column>
                                          <h:column>
                                          <s:button value="Play" action="#{showuservoicemessage.play}"></s:button>
                                          </h:column>
                                  </h:dataTable>

                                  I am using the <object> tag to insert the player on the xhtml page. With the autostart option set to true.

                                  <object classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" width="120" height="30">
                                                                                                    <param name="URL" value= {showuservoicemessage.currentVoiceMessage}"/>
                                           <param name="autoStart" value="true"/>
                                           <param name="uiMode" value="mini"/>
                                          <embed src="#{showuservoicemessage.currentVoiceMessage}" autostart="true"/>
                                  </object>

                                  However when the user presses delete, the last played message repeats itself. I believe this is happening because the "autostart=true". Can you please guide to have this problem fixed? Or if you could please suggest any other mechanism by which I can play the message?

                                  Regards,
                                  Raziya

                                    Never done it, but does it work if you place a s:div with some rendered condition that is flipped to false when you think the object-tag might fire when it shouldn't?
