X-application Query Error

Hi everyone…
I am trying to use a dropdown menu to query on a particular item. Howvever I get an error of the type Collection for doctype not identified.
I also want to report a funny thing, when I get the first xml element from my database and try to perform any query on it, i get an error, so I inserted a “dummy” xml tag with values i wont ever encounter and then all the other tags started working. Is there any problem with X-application where the first element is not returned properly? Please let me know

X-Application Version: 3.1.2, 3.1.1
Tamino Version : 3.1.1
Platform : NT, Win2k, Solaris, …
WebContainer : Tomcat 3.3
JDK Version : 1.3.1

Hello Parth,

have a look at the following topic:

Joining Two Doctypes …

Monica had a problem that sounds similar to yours.

Did you register the second doctype within the web.xml file?

If this does not solve your problem post the complete stack trace of the exception you have got to the community. Then, we have a better chance to analyze your problem correctly.

For the second problem you described it would be helpful to have a look at your Java Server Page. My first guess is, a context (document or loop) is referred by a tag (e.g. display, count) before the context is defined.
