Unknown expression builder output

Hello

I use BIRT 2.2.1 windows all in one package and since I used this package I have a corious problem. If I open the expression builder an then click available data sets, it doesn't show me my datasets name but org.eclipse.birt.report.model.api.OdaDataSetHandle@4483e3.
This is a little bit confusing if I have a few datasets to find the right one.

I use java 1.6.0_11 and have tried it with the -classpath parameter and 1.5.0 16 too, but without success

Do anyone know this problem ?

Thanks for tips
Rob

What element are you trying to write a script on top of? Data Sets are bound to elements of the report and as such, you need to make sure you are scripting against a dynamic element (like a table or a chart). Once you create an element, like a table for example, you need to make sure that element has a data set bound to it. This will ensure your data set appears as an available data set via the expression editor.

Hi

Yes the DataSet is a query against a database table, and it shows the correct fields and values, but the name of the DataSet is in a corious format like described above and not in the name which I configured it.
The same thing happens if I choose the birts internal laogarythmic && || actions.

Can you attach a copy of your report design to the thread so I can have a look?

Hi

Thanks that I can givé you this file to review
Its a simple report with the classic cars database in wich I concatenate the last and first name in the 3rd column. And there these problem resists if I try to choose Category/Available Data Sets -> Sub-Category/org.eclipse.birt.report.model.api.OdaDataSetHandle@1dae827 -> Double Click to insert/ContactLastname

Hope this can help
Thanks
