can you log a bug for this? To work around it you could use the birt
runtime instead of starting the chart engine in stand alone. Just use
code like:
PlatformConfig pf = new PlatformConfig();
pf.setBIRTHome("C:/birt/birt-runtime-2_6_1/birt-runtime-2_6_1/ReportEngine ");
//Either add the chart sdk or runtime to your eclipse plugins and set
BIRT home to that directory
//which must include the osgi plugin or use the BIRT runtime
//pf.setBIRTHome("C:/birt/birt-charts-2_2_1_1/ChartSDK/Eclipse/ ");
//Returns a singleton instance of the Chart Engine
ChartEngine ce = ChartEngine.instance(pf);
//Returns a singleton instance of the Generator
IGenerator gr = ce.getGenerator();
Add the jars in the reportengine/lib to your build path and set the BIRT
home to the appropriate directory.
