    Page is refreshed after each Ajax call

    Alexander Parij Newbie

      I have <rich:dataTable> and for each row I have a checkbox <h:selectBooleanCheckbox> , when I click on the checkbox it creates new Ajax request with <a4j:support> and afterwards refreshes the page, it is really annoying and for example any a4j:log I have is immediately cleared. disableDefault=true is not helping .
      How can I prevent this effect ?I know that this part of code causes it ....

      <h:selectBooleanCheckbox id="checkBoxEach" value="# {accountListController.checkedUsernames[account.username]}" immidiate="false" >
       <a4j:support event="onchange" disableDefault="true" ajaxSingle="true" >
       <a4j:actionparam name="username" value="#{account.username}" assignTo="#{accountListController.username}"/>
      </a4j:support>
      </h:selectBooleanCheckbox>

          I have also noticed a difference in how the browsers behave ,
          IE7 will not execute the first Ajax call , only when I check on second checkbox it will start executing , and it will execute for the first checked row only and then refresh the whole page.
          FF3 it will execute as expected with each "onchange" event and then refresh the page.

            I wrote a simple echo xhtml from the developer guide and it still refreshes the page..
            Is it a problem with my bean configuration ? navigation case ?

              Using Live Http Headers I can see that my POST header contains parameters
              that trigger the redirect to itself hence the refresh of the page.
              But why the richfaces library puts this values ?

              Ajax-Response: redirect
              Location: /account/view.jsf

                Try to figure out why the session cannot be restored.

                  Sorry , but it was problem on our side.
                  We were redirecting every POST request ( PRG pattern - Post/Redirect/Get)
                  but if before it was just fine for the JSF pages navigation , for the Ajax Post requests it caused the redirection to self...
                  Sorry again :)
