Uhg...your post brings back horrible memories. I know exactly what you mean. I had this problem in December and spent about 20 hours of my time picking through the code and fixing the places where the ItemID was being dropped. I finally got it working for everything except group registrations--and, in the end, I had to just manually type in the actual ItemID right into the DT Register code in order for the component to retain my template. I couldn\'t figure out how to get it to return the user to the custom template after PayPal without hardcoding the ItemID. I was really disappointed that I had to jury-rig it this way in order to get around the problem after I had spent so many hours trying to fix it the right way.
All you have to do to test this is assign a non-default template to the menu link for the component and run through testing as individual and group. I am not using the membership registration feature, so whether or not the ItemID is retained if someone is logged into the site is not something I have an answer for.
Supposedly this was solved in the January bug fixes. Which version are you using? I have not upgraded to the newer version because (1) I\'m not sure the ItemID problem has really been solved and (2) while picking through the code in search of ItemID occurrences, I cleaned out all the table-formatted HTML and replaced it with standard HTML text tags instead (e.g., <p> or <h1> or <h2> or <div> ) so that the component would pick up its styles from my template\'s CSS. Someone went bonkers with table formatting when they made the template up for this code. This makes it difficult (in some cases impossible) to format nicely so that it matches your template. I hope this also is resolved in the upcoming native 1.5 version of the software.
It\'s not at all hard to understand why someone would want to use a non-standard template with this component. Lots of people who don\'t use Joomla create special websites for their conferences themed to the conference logo, graphics, etc. When you use Joomla, the easiest way to handle this is to use an alternative template for the pages dealing with your conference so that the colors and graphics coordinate with your conference brochure and other literature. That way you don\'t need to create a separate Joomla install just to handle a single conference.
