Hi,
I have a problem with dynamic images and BIRT.
I have done a simple test report that contains a table with two columns,
the first one contains an image and the second one contains a string.
The second column works well, there is a new string value on each line,
and that string value corresponds to the value of the resultset of the
connected dataset. The first column however does not correspond to the
resultset. The image of the first line in the table is correct, but the
image on the following rows does not change, the first image retrieved
from the resultset is used again and again.
This is what I have come up with so far.
* The Blob is correctly retrieved from the resultset. Hence, I think
that the problem is not within ODA-framework.
* The SmartCache seems to be correctly populated.
* The query of the dataset is executed multiple times, it seems that the
query is executed once for ever image. If my example resultset contains
n results the query is executed n+1 times.
* The same resultset seems to be used for each and every string, a
different resultset is used every time an image is retrieved, which in
turn leads to that the getCurrentResult() method is returning the first
result each and every time.
We are using our own custom ODA so I can not easily provide you guys
with a test case.
I wonder if somebody else have experienced the same problem, or am I the
first one?
Best regards

An easy search in Bugzilla gave me the answer of my problem, I had,
incorrectly, bound the dataset to the dynamic image as well as the table.
Typically I spend two days debugging BIRT, just to find out that my
knowledge of report design suck. :-(
