Re: Server side error messages need to be cleared when resubmitted the page to prevent duplicate display

[Yannis BRES <ya...@gmail.com>]

Hi !

We also faced this issue, and the quickest / less dirty way we found to
address it was to write a small Java Script method, that gets called on all
form submissions using onsubmit :
  <tr:form id="smc_domain_form"
          onsubmit="SMCClearAllMsg();return true;">

This method first removes the global messages that are in displayed by
<h:messages
id="smc_global_messages" globalOnly="true" .../> and then removes whatever
non global messages that can appear on the page :
  function SMCClearAllMsg()
  {
      // remove global messages (with its list bullet)
      var global_msg= document.getElementById("smc_global_messages");

      if (global_msg != null)
      {
          global_msg.style.display='none';
      }

      // remove each message but do not remove client-side validation from
trinidad.
      // Note: only our messages where we set class=OraInlineErrorText are
involved
      // message generated by client-side validation usually have class=x9e
(compacted).
      var spans = document.getElementsByTagName("span");
      for ( var i = 0; i < spans.length; i++)
      {
          if (   (spans[i].className == "OraInlineErrorText")
              && (spans[i].parentNode.className !=
"af_panelFormLayout_message-cell")
              && (spans[i].parentNode.className !=
"AFComponentMessageCell"))
          {
              spans[i].style.display = 'none';
          }
      }
  }

Of course, the question remains :  shouldn't this be done by Trinidad ?

Hope this helped,
         Yannis
