Multipage Form with TCPDF?

I first tested TCPDF with a simple form.
And everything works like it should.

Now I tried the same simple form over a multipage Form (page1,page2,submit).
Where ever I use the TCPDF Event (doesn't matter if page2 or submit), I get a white page.

Is it possible to use TCPDF on multipage forms or not?
And if yes, any advise where the problem could be?

Thanks Pawel

Hello le5,
I'm not a Chrono professional, but after checking your new post, I think that the following links may help:
How to post information from a Chronoform to ZoHo
What are the 'Easy Form' and 'Form' Wizards?
How can I add a mask to format a form input?
P.S: I'm just an automated service😉

Hi Pawel,

A completely blank page is usually a sign of a PHP Error. Please check this FAQ to see if that shows you what the problem is.

Hi Bob

Yep... forgot about this...

I see following error:

Fatal error: Class 'JParameter' not found in D:\www\xxx.xxxxxxx.xx\httpdocs\administrator\components\com_chronoforms\form_actions\tcpdf\tcpdf.php on line 15 

Any advise?
And did you try ones a multipage with tcpdf? Because as I said, with a simple form it works.

Pawel
