RichFaces 4.3.x performance

[blebleskeble]

Hi all,

I'm using richfaces 4.2.0 on my web project. Lately I tried to update to version 4.3.0 but I was facing strange issue:

After page is loaded, there should be some javascripts launched (jQuery(document).ready(.... ), but there is about 30s delay between page load and js start. After profiling of js i found out that there is no problem with scripts. I also found following:

• only in IE9
• only when loaded page is big - there are many input fields (or selects or textareas) on page. (many = 100+)
• also with 4.3.1 and 4.3.2 (4.2.0 works fine)

Does anyone know about this or some similar issue?

(Sorry for not posting code, but I'm not allowed to do so.)

Used env:

• Apache Tomcat Version 7.0.33
• MyFaces 2.1.10

Hi,

this is an issue of jQuery (or rather IE). There seem to be some workarounds and if they don't work you can try downgrading jQuery (with static resource mappings) but that may cause more issues - RF 4.2.0 Final uses jQuery-1.7.1, RF 4.3.X uses 1.8.X. Do not upgrade jQuery to 1.9.X or higher, it is incompatible with RichFaces.

Oh the irony.  OSS FTW!

FYI: There are commercial/confidential support channels availble for RichFaces.  Have a look at the WFK product from Red Hat:

Hi,

is there any chance we will see upgrade of JQuery to 1.9.1 or 1.10.1 in RichFaces 4.3.3 planned for September this year?

Hey Michal, could you file an component upgrade request in issue tracker and elaborate there why jQuery 1.9.x / 1.10.x is incompatible with RF4.3?

jQuery 1.9 introduced a number of breaking changes, remvoing many previously depracated features.  See the jQuery 1.9 upgrade guide for details:

http://jquery.com/upgrade-guide/1.9/

We will surely upgrade RichFaces to use jQuery 1.9+ at some point, but the risk in doing so too early is that it will break other jQuery plugins that have not yet upgraded to the new API.

OTOH, with RF 5 we are considering upgrading to jQuery 2.0.
