I'm using Birt 2.2.
In the Initialize section of the script, I have added
rwcnt = 0;
In the onFetch section of my data set I have
rwcnt += 1;
and then I am using rwcnt in the visibility section to hide or show
different parts of the report if no data is returned.
However when I edit the data set and try to preview the results I get the
following error:
A BIRT exception occurred.
Plug-in Provider:Eclipse.org
Plug-in Name:BIRT Data Engine
Plug-in ID:org.eclipse.birt.data
Version:2.2.0.v200706221
Error Code:data.engine.BirtException
Error Message:A BIRT exception occurred: Error evaluating Javascript
expression. Script engine error: ReferenceError: "rwcnt" is not defined.
(DataSet[PDI].__bm_onFetch#2)
Script source: DataSet[PDI].__bm_onFetch, line: 1, text:
__bm_onFetch(). See next exception for more information.
Error evaluating Javascript expression. Script engine error: ReferenceError:
"rwcnt" is not defined. (DataSet[PDI].__bm_onFetch#2)
Script source: DataSet[PDI].__bm_onFetch, line: 1, text:

Am I doing this right? It seems to work in thje report itself, but I need to
preview the data. Is there another way of doing this?

Andy,
Set the rwcnt=0 in the beforeOpen of the dataset.
Take a look at the attached example.
