COMMAND BUTTON NEEDS TO BE CLICKED TWICE TO SAVE VALUES

Question

Hello,
I have a problem that I'm pretty much spent hours trying to fix but failed to do so.
I have a jsf page with a datatable bound to a component.
I have updatable fields inside the table and a button below to save changes to the table.
When I make a change the first time, and then hit the button, i get the action, and I save the value with no problems.
However if right after it re-renders, I make another change in the table , and save button again it won't invoke the backing bean save method.
The setter for the datatable binding property does get invoked however, it disregards the changes i just made to the table.....
If i make changes for the third time...and hit save...it works...
All my backing beans are request scope
any clues???? i appreciate your help!!
     public void save(ActionEvent e) {
          log.debug("Im entering save user");
          currentSession.setCurrentSession(client);
          FacesContext.getCurrentInstance().renderResponse();
          organicManager.saveAppUsers(client, (List)appUsersTable.getValue());
          appUsersTable.setValue(new ArrayList(organicManager.getAppUsers(client)));
<t:commandLink  actionListener="#{appUsersBean.save}" rendered="#{!appUsersBean.adding}">
     <h:outputText value="save" style="font-weight:bold;font-size:14px;text-decoration:none"/>
</t:commandLink>
<t:dataTable
binding="#{appUsersBean.appUsersTable}"
          id="appUsersTable"
          var="userRow"
          style="font-family:arial;font-size:11px;"
          rendered="#{!appUsersBean.adding}"
          bgcolor="lightcyan"
          preserveDataModel="true"
     >
     <h:column>
          <f:facet name="header">
               <h:outputText value="Username"/>
          </f:facet>          
          <h:inputText value="#{userRow.username}" readonly="true"  style="font-family:arial;font-size:10px" />
     </h:column>
     <h:column>
          <f:facet name="header">
               <h:outputText value="FirstName"/>
          </f:facet>          
          <h:inputText value="#{userRow.firstName}" maxlength="50"  style="font-family:arial;font-size:10px" />
     </h:column>
     <h:column>
          <f:facet name="header">
               <h:outputText value="LastName"/>
          </f:facet>          
          <h:inputText value="#{userRow.lastName}" maxlength="50" style="font-family:arial;font-size:10px" />
     </h:column>

Answer 1

Yes.
When I click the Close Window button, the Confirm close dialog window closes . . . but there is another one right behind it. I have to click the Close Window button again, and only then does the Firefox browser window close.
A couple of factors are involved:
1. I have "Warm me when I have multiple tabs" set to on.
2. Two or more tabs must be open in the Firefox window
3. I have at least two Firefox browser windows already open (not sure about this one, yet)
I thought before that it was necessary to have a dialogue box from a different program open, but this is not necessary for the bug to appear.
Thank you for your help!
