Hi,
currently i'm testing the BIRT 2.1.1 Version. Under 2.1.0 it works fine
but after updating the following error occurs:
Caused by: org.eclipse.birt.data.engine.core.DataException: A BIRT
exception occurred: Error evaluating Javascript expression. Script
engine error: TypeError: getDataSet is not a function.
(DataSet[dataSet1].__bm_FETCH#2)
Script source: DataSet[dataSet1].__bm_FETCH, line: 1, text:
__bm_FETCH(). See next exception for more information.
Error evaluating Javascript expression. Script engine error: TypeError:
getDataSet is not a function. (DataSet[dataSet1].__bm_FETCH#2)
Script source: DataSet[dataSet1].__bm_FETCH, line: 1, text:
__bm_FETCH()
It seems that birt can not find the method getDataSet from the
dataCollection object.
Has anyone an idea where the error is or what i can do?
The following lines shows how i build the javascript to fetch the data:
==============================
ScriptDataSetHandle ds = design.getElementFactory().newScriptDataSet(
dataSetName );
design.getDataSets().add( ds );
ds.setDataSource( dataSource.getName() );
ds.setOpen( "count = 0;" );
StringBuffer sb = new StringBuffer();
sb.append( "var ds = params[\"dataCollection\"].getDataSet(\""
).append( dataSetName ).append( "\");\n" );
sb.append( "if( count < ds.size() )\n" );
sb.append( "{\n" );
sb.append( "var columns = ds.get(count);\n" );
for( int i=0; i<columns.length; i++ )
{
sb.append( "dataSetRow[\"" ).append( columns[i].getName() ).append(
"\"]=columns[" );
sb.append( i ).append( "];\n");
}
sb.append( "count++;\n" );
sb.append( "return true;\n" );
sb.append( "}\n" );
sb.append( "return false;\n" );
ds.setFetch( sb.toString() );
=============================
Following lines shows how i start generating the report:
======================
IRunAndRenderTask runTask = birtEngine.createRunAndRenderTask(
ticket.getReportDescriptorImpl().getBirtDesignFile().getAbso lutePath(),
design );
// Run birt task
runTask.setLocale( session.getOutputLocale() );
runTask.setRenderOption( option );
runTask.setAppContext( appCtx );
runTask.setParameterValue( "dataCollection", session.getDataCollection() );
runTask.setParameterValue( "renderUtils", session.getRenderUtils() );
runTask.setParameterValue( "linkBuilder", session.getLinkBuilder() );
runTask.run();
=====================
Complete error message:
The following items have errors:
Table (id = 78):
- There are errors evaluating script "var ds =
