Sebastian Wenzky updated COCOON-2031:
-------------------------------------


I suppose, the problem belongs to "mutli-user" access at runtime access to an particular XSP, which wasn´t at this time still compiled. For Instance, if two users tried to retriving one resource from web (for instance: user.xsp), and furthermore this xsp wasn´t still compiled, than appears this error and nothing works after this appearance...

> 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
