RichFaces generating blank css, Please Help!

zahidmaqbool Sep 24, 2008 6:19 PM

Hi,

I have run into a rather unusual problem, all of my pages from time to time appear without any skin and none of the richfaces components will work. They styles are not applied. When I view the page source, and try to check the css by richfaces they all return empty. Please note this only happens from time to time. Like one morning it will happen, then suddenly it will be alright in the evening. Also the strange thing is that it only happens with this particular project. In this one I am using richfaces 3.2.2.
As you can see i am also using org.richfaces.SKIN and setting it to bluesky.

This is how the page looks like:

The above logs are rather common for all the projects.

I am using richfaces 3.2.2 and seam 2.0.2

This problem only appears from time to time, but it does appear everyday.

Any help would be appreciated!

Thanks

Hi,

I am also having the same issue with Seam 2.0.1.GA and Richfaces 3.2.1.GA. I noticed the issue on our staging server that has been up for a long time. The CSS returned is consistently blank for the past 2 days. I will update whether the problem goes away when the server is restarted. I bet it will.

More specifically the problem can be displayed by using the CSS link directly in the browser, it returns an empty HTML body.

/ReferenceDataManager/a4j_3_2_1-SNAPSHOTorg/richfaces/skin-ext-classes.xcss/DATB/eAF7sqpgb-jyGdIAFrMEaw__

Here are the richfaces specific config in my web.xml:

<context-param> <param-name>org.richfaces.SKIN</param-name> <param-value>blueSky</param-value> </context-param> <context-param> <param-name>org.ajax4jsf.xmlparser.ORDER</param-name> <param-value>NEKO</param-value> </context-param>  <context-param> <param-name>org.richfaces.LoadScriptStrategy</param-name> <param-value>ALL</param-value> </context-param> <context-param> <param-name>org.ajax4jsf.COMPRESS_SCRIPT</param-name> <param-value>false</param-value> </context-param>  <context-param> <param-name>org.richfaces.LoadStyleStrategy</param-name> <param-value>ALL</param-value> </context-param> <context-param> <param-name>org.ajax4jsf.VIEW_HANDLERS</param-name> <param-value>com.sun.facelets.FaceletViewHandler</param-value> </context-param>

Any ideas what could be wrong? I will have to embed the richfaces CSS content in the application CSS as a workaround. We really cannot gamble and always need the CSS for proper rendering.

Hello,

Can you please check how CSS resources are loading using Firebug 'Net' tab or Fiddler tool? Are there any exceptions?

Hi,

Since the problem is intermittent I don't know how to reproduce. I cannot risk have it happening in staging or prod again therefore I copied all CSS contents generated by /a4j_3_2_1-SNAPSHOTorg/richfaces/skin-ext-classes.xcss/DATB/eAF7sqpgb-jyGdIAFrMEaw__ link into my own CSS to ensure it is always loaded.

Making directly the HTTP request for /a4j_3_2_1-SNAPSHOTorg/richfaces/skin-ext-classes.xcss/DATB/eAF7sqpgb-jyGdIAFrMEaw__ returned empty content (it normally returns css styles), no exceptions to be seen on the server logs. This is as much as I can tell you.
