Issue with LoadStyleStrategy

[amandaesweeney]

Hello,

I am trying to enhance the performance of my application. After doing some research I found that setting the LoadStyleStrategy to ALL can help, so I added the following to my web.xml

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

    </context-param>

This does help with the performance however it also causes problems, the application loads but some of the styles do not. If I set the LoadStyleStrategy to DEFAULT, the application loads fine.

Strangely the issue is not present with Firefox only IE (I'm using IE8). I used HttpWatch to compare the http requests for both browsers and for Firefox the following additional reqeusts are made

http://localhost:9080/alm/a4j/g/3_3_2.SR1org.richfaces.renderkit.html.GradientA/DATB/eAH7!!3Tj2v7mAAZZAV3.xhtml

http://localhost:9080/alm/a4j/g/3_3_2.SR1org.richfaces.renderkit.images.TabGradientA/DATB/eAH7f-!Y!!!!mQAZCwWj.xhtml

http://localhost:9080/alm/a4j/g/3_3_2.SR1org.richfaces.renderkit.images.TabStripeImage/DATB/eAH7cW0fAAVVAo0_.xhtml

The weird thing is, if I restart WAS and clear my temporary internet files for IE the issue goes away, but it mysteriously appears again after awhile.

Has anyone come across this before? I'd like to be able to use this setting as it really does help with performance, but I can't use it if it affects the layout. I'm using richfaces 3.3.2.

Any help would be greatly appreciated.

Thanks,

Amanda

it seems that some resources just not getting loaded. could you please check in some sniffer for resource requests statuses when issue appears?

Hi Ilya,

Thanks for your quick response. I'm using HttpRequest which doesn't provide a status for request responses that failed, it just seems to not show those requests. Can you recommend a program to do what you're asking?

Also, the issue is actually occuring in Firefox now too so it is not a browser issue.

try fiddler.

Hi Ilya,

Fiddler doesn't show any resource request errors when the issue appears either. The resources simply aren't loaded.

I found a workaround for a similar display issue I was having awhile ago, see http://community.jboss.org/message/551495#551495 for more details.

But I can't seem to apply that workaround here, do you have any idea why over time the resources fail to load properly?
