Cache problem

[Didier Frick <df...@dial.eunet.ch>]

Hi,
I'm currently using a two-stage XSL transformation, with one XSL stylesheet
including a link to another stylesheet and a cocoon processing instruction
in its XML output.

It works, but I'm having a problem with the cache. Suppose the processing
goes like this:

Producer -> XSL (stylesheet A.xsl) -> XSL (stylesheet B.xsl) -> HTML

Now, if I change stylesheet A the cache notices that it has changed and 
regenerates the page. But if I change stylesheet B.xsl, the old cached
version is served.

After going through the code, I can't understand how it is the case,
since the XSL processor should appear twice in the page changeables,
once with stylesheet A as a dependency, and once with stylesheet B.

I did an strace on the process and verified that it indeeds checks
the last modification date for file A.xsl, but not for B.xsl.

Can anyone relate to this ?

TIA,

		Didier

This is fixed in Cocoon 1.7.3-dev
