Subject [jira] Updated: (COCOON-2031) Language Exception at Runtime by the attempt to compile a random XSP
Date Wed, 25 Jul 2007 21:44:31 GMT

Antonio Gallardo updated COCOON-2031:
-------------------------------------

    Status: On Hold  (was: Open)

Hi Sebastian,

The issue seems to be a race condition that was fixed in 2.1.10: (taken from http://cocoon.apache.org/2.1/changes.html
)

"XSP block: Fix regression introduced in 2.1.8 that under specific circumstances logicsheets
were not applied, leading to compilation errors. This manifested itself only if a) two XSPs
referred to the same custom logicsheet by a relative location path, b) the custom logicsheet
used another logicsheet, and c) the built-in logicsheet's namespace was not mentioned in xsp:page.
The compilation errors occurred always when calling the second XSP for the first time. Fix
also race condition which could lead to similar XSP compilation errors under high load when
accessing the same logicsheet for the first time. Committed by AN."

Let us know if just moving to cocon 2.1.10 fix the issue.

> Indeed, i have no explanation, for my confuse problem and i don´t know, what kind of
state occures that. Normally, when cocoon starts at first time there are no problems. I can
go, visit different pages (which will be correctly compiled) and so on... But sometimes later
the error occurs suddenly, without any real worthwhile exception message to me.

> Once i´ve already said this, that this error occurs at a different XSP as before. Why
ever. Futhuermore, as soon as this error appears, it seems to be that cocoon will turn off
his intern compiler, so that following XSP Sites which was at this time still not visit(and
so not compiled!) can not compiled by cocoon anymore until cocoon restarts.
> I don´t know, what this is, but i still believe, its possibly that this error can be
a bug of cocoon.
> Can anyone help ?
> Best Regards
