Richfaces panel styles suddenly wont load

This is really frustrating ...

Suddenly the richfaces panel styles have just stopped loading.

The generated css links:

<link rel='stylesheet'  type='text/css' href='/MCSA-web/a4j_3_1_4.GAcss/panel.xcss/DATB/eAFTL4ziAQACswD..mcsa' />
<link rel='stylesheet'  type='text/css' href='/MCSA-web/a4j_3_1_4.GAcss/table.xcss/DATB/eAFTL4ziAQACswD..mcsa' />

The styles from the 'table.xcss' style load correctly. The styles from 'panel.xcss' portion do not load, when I try to expand these styles for viewing in firebug I get the message:

'Failed to load source for: http://host-test/MCSA-web/a4j_3_1_4.GAcss/panel.xcss/DATB/eAFTL4ziAQACswD..mcsa'

However, another JSF/Richfaces app I have running on the same server is still able to load these styles ... this other application uses the EXACT SAME web.xml and faces-config.xml files (I literally copy/pasted them).

I have tried:

<context-param>
    <param-name>org.richfaces.LoadStyleStrategy</param-name>
    <param-value>ALL</param-value>
</context-param>

but this does not solve the issue.

... I'm totally at a loss here, does anyone have any experience with this? Why is it just the panel styles that fail???

Also you might notice I'm using richfaces 3.14, can't get around this sadly so I'm stuck with that at the moment. I've seen various other questions on many sites where people have been having problems with richfaces styles loading (various versions of richfaces) but I've yet to find a soluti开发者_运维知识库on that works.

:(

Ok well I found out the cause though I'm sort of unclear why it was happening only sometimes ...

Anyway, I'm using a PhaseListener to handle access/authorization, it looks like sometimes this would block a resource load request so I added the following check before the authorization checking code and it seems to always load now:

if (!event.getSource().getClass().equals(ResourceLifecycle.class))
