Charts in BIRT Reports

Hi all,

My question is regarding charts within BIRT. I have couple of charts which already exist in the system and they have the proper formatting which needs to be followed by the new charts too.

Since to convert the new charts to the require format needs several steps, what I tried was to make a copy of an old functional chart and change it's data set.

But it does not work. Instead, it gives me the following error:
"exception.unknown.trigger.datatype "

What could possibly be the reason?

I check the parameters and they are correct too.

Although, if I create a new chart and pass the same dataset, it does works. So, I believe there is something wrong with chart I copied.

Many Thanks,
Abhi

Hi Abhi,

I have not heard of this issue before. What version of BIRT are you using? Could you recreate this issue with the sample database at all? You may take a look in the XML Source at a working chart and a failing chart and see what differences there are. This may help que you in to where the problem starts.

Hi,

Sounds like you need to reselect the data set in your chart. I've seen this happening before in the RCP designer, where the chart dialog gives an error. Best thing to do is to select the report element radio, then reselect data set radio and then select your data set again. That should do the trick, unless your data set does not have the same column names and/or data types.
