Hi,

due to the fact that layout it going to disappear from primefaces I have tried to check the PE option but found a "strange" behavior that I am trying to solve for the last couple of days with no success. Namely, when the layout is refreshed I am able to LITERALLY SEE how the panes' sizes/position are calculating and "jumping" all over the page (especially when the panes contains some heavy stuff inside - than this jumping may take 3-5 secs). Of course in the showcase everything is ok (details below)

The page:

Now, my page source:

</script></body>

</html>
Now when I compare my page source with the PE showcase what looks different is:

Code: Select all

<script type="text/javascript" src="/asr/javax.faces.resource/jquery/jquery.js.xhtml?ln=primefaces&amp;v=6.2"></script>
<script type="text/javascript" src="/asr/javax.faces.resource/jquery/jquery-plugins.js.xhtml?ln=primefaces&amp;v=6.2"></script>
<script type="text/javascript" src="/asr/javax.faces.resource/core.js.xhtml?ln=primefaces&amp;v=6.2"></script>
<script type="text/javascript" src="/asr/javax.faces.resource/primefaces-extensions.js.xhtml?ln=primefaces-extensions&amp;v=6.2.9"></script>
<script type="text/javascript" src="/asr/javax.faces.resource/layout/layout.js.xhtml?ln=primefaces-extensions&amp;v=6.2.9"></script>

And finally when I debug in chrome and compare with the PE showcase (preview frame) one can see that "pane jumping" (marked with red - on mine there is a phase when the layout is OK - then the form is changed again to some basics - and finally comes back to the desired original shape. In PE showcase form is not changed from the beginning):

Do you have any idea where/what/etc ? Getting desperate .....
Tricks like "primefaces.MOVE_SCRIPTS_TO_BOTTOM" didn't help ...

Checked with primefaces 6.0 ,6.2 and PE 6.2.8 and 6.2.9

So if you look in the showcase code here is what I do...

CSS

Code: Select all

html {
    overflow: auto !important;
    visibility: hidden;
}
JavaScript:

Code: Select all

var Showcase = (function() {
   return {
      /**
       * https://stackoverflow.com/questions/9550760/hide-page-until-everything-is-loaded-advanced/9551066
       */
      displayPage : function() {
         $(document).ready(function() {
         
            // show the HTML pane after everything has been adjusted
            // https://stackoverflow.com/questions/9550760/hide-page-until-everything-is-loaded-advanced/9551066
            document.getElementsByTagName("html")[0].style.visibility = "visible";
         });
      },
XHTML: The in my main layout.xhtml I call this JS on page load.

Code: Select all

<h:outputScript id="displayPage" target="body">
            Showcase.displayPage();
</h:outputScript>

Hi Melloware,

is this a workaround or the desired solution? (primefaces layout does not require additional "magic" - maybe I just do sth wrong?!)

Regards,
herbu

PS
if that is the part of PE layout solution - maybe should be mentioned somewhere ... like docs/showcase

I think it has to do with how both components are built. They use the same underlying Jquery plugin but the way the layout works is completely different.

I would say my solution above is a workaround.
