Subject [jira] Issue Comment Edited: (TAP5-541) Regression: Parameter namespacePrefix was null
Date Fri, 27 Feb 2009 16:25:12 GMT

----------------------------------------------------------

I can verify this behaviour. In fact I posted to the mailing list about it a while ago.

see http://markmail.org/message/sqlqx3ljnd4ooy7r

Anyway, I am not sure that the reason is the missing declaration on the title tag, because
I got it working again (don't know how), but did not change anything about the declarations.

> For me it seems that Tapestry requires a namespace declaration on the <title> tag.
But I have already the default namespace declaration on
> the <html xmlns="http://www.w3.org/1999/xhtml"> tag.
> P.S. with only <html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd">
it fails also. But it did work on Tapestry 5.0.18
> Thanks,
