Hi all,
I'm experiencing a little difficulty in getting SEAM's PDF functionality to work.
I can get what I want if I put all my variables into a SESSION scope. But as soon as I want to try use a CONVERSATION scope the PDF has no data in it.
Now I'm assuming that this is because of the way that PDF's are handled. So, I guess my question is, What is the work around?
I have a page where users search for records based on some criteria. My aim is to have a button on the page which will generate a PDF document with these results in them and display them in an iframe or equivalent below, allowing them to get a print friendly version of the records.
Currently I'm experiencing considerable difficulty in passing data to the xhtml page where my pdf is defined.
here is some of the more necessary code
Don't worry too much about the reference to GekkoReport it is just a bunch of getters and setters at the moment.

That code is the best implementation I've had so far in that I at least get results on my page but...... I don't want to be putting all this data into my SESSION scope.
I'll keep looking for some decent examples and reading doco but... any ideas would be great. :)
Thanks
