Hi,

Just installed a fresh xwiki beta 4 on WAS CE 1.1 (and MySQL 5.0.22-Debian_0ubuntu6.06.2). And have a couple of probs :( Appologies in advance for the lenght of the email - that's stack traces for you ;)

When I started the server I got a number of warning and errors I've not seen before - are these "normal" ?

Yes, they are somewhat "normal", meaning that we know about them ( http://jira.xwiki.org/jira/browse/XWIKI-623 ), they are not major errors, but they need to be checked out and fixed.

Although they claim to be coming from Main.WebHome, they don't exist at the line referenced in the document (or in the included Main.Dashboard (AFAICS)). Seems like it might be a problem in the skin.

Main.WebHome is the document being displayed, but the error is in a skin (.vm) file.

Also,

When I import the beta 4 XAR, the Panels.PanelWizard failed to import.... I then selected just this page again (from the import wizard) and it imported ok. Is this expected (I was wondering if the dependency on XWIKI.TagClass mean that the XWIKI space needs to imported first... but then I've not seen this behaviour before).

This is not expected, it is an error. I don't know what causes it, maybe you should stalk Vincent about this.

Unfortunatly I suspect that the error message showing the reason for the failure was swallowed by the following exception I found in the logs :

... more removed for the sake of sanity :)

No, I don't think this causes the above error.

Any advice ?

Ask Vincent for assistance.
