Hello,

according to the Stacktrace, the error is sent from the Tamino API for Java. I will ask my colleagues developing this API what the reason is for this error.

For ananlyzing it, it would be useful to know more details.
The error occurs within the /Property/Search.jsp. Is this:
(A) the normal example page of our Property example?
(B) a page you generated or modified?

If (A), is it possible to reproduce this error? Does it occur every time you request the search page?

If (B), could you post this JSP for I want to have a look at its select tag. And perhaps, can reproduce the error on our machine.

I think, this would be very helpful for my colleagues.

Many thanks,
Christian.
