Hi! i'm using the tcpdf extension on a 4.2 ezPublish installation... i am able to create the pdf content, but after creating it, on the next html-page served the html code is mixed with pdf code.. so the browser crashes. It doesn't happens every time, and when it happens it is only the next page served, then it works again.

Could it be some cache problems? Maybe the pdf code is cached and then mixed with html code...on this mixed code, i can see the pdf headers on the last lines of the html page (and just before the pdf code itseld)

We have good experience with http://projects.ez.no/paradoxpdf

So try that extension if you can't solve your current problem...

I noticed that, when the wrong html page is served, the $module_result.uri is that of the pdf view page, not the one being served... i don't understand it..

every ez url is changed by this one:

"/en/tcpdf/artykul/objectid/645/nodeid/406"
