Would you please attache the class ValuationEnum for me to reproduce? Created attachment 181268 [details]
ValuationEnum class to reproduce problem
I attached the ValuationEnum class. However it is probably not required as the problem occurs with every enum and every static function. Cheers, Tim Hi, I can not reproduce this issue with 2.5.2 release build. Please find my attached example, which used both static function and the Enum class you provided: enumValue = ValuationEnum.FAIL; birtVersion = BIRTRow.getVersion(); The script dataset works fine. Created attachment 181359 [details]
The example that works fine in 2.5.2 and 2.6.1 release
Thanks for your answer. I think my problem may be related to the deployment inside an RCP application. I made a small example RCP app which can be used to reproduce the problem. Created attachment 181363 [details]
Sample RCP app to reproduce
I'd investigated the RCP sample. I found user set application class load in each task in Viewer.java, it's not correct. User should set it at report engine level instead of task level.
public void widgetSelected(SelectionEvent e) {
IReportEngineFactory factory = (IReportEngineFactory) Platform .createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
EngineConfig config = new EngineConfig();
HashMap appcontext = config.getAppContext();
appcontext.put(EngineConstants.APPCONTEXT_CLASSLOADER_KEY, ValuationEnum.class.getClassLoader());
config.setAppContext(appcontext);
IReportEngine engine = factory.createReportEngine(config);
.......
}
Verified in daily build 20101104-0630. OK, thanks for investigating this. Is there any documentation available for these things (i.e. which property is valid in which scope etc.)? |
Hi, I have BIRT (2.5.2) deployed in our Eclipse RCP application (based on Eclipse 3.5). I am using a scripted data source. When I now try to access static functions in a static way or Enums which are located in one of the plugins of my RCP app, I get errors. This is what I do in a script part: importPackage(Packages.de.micronova.exam.report); var x = ProjectHome.getRootProject(session); or importPackage(Packages.de.micronova.exam.report.enumeration); if (x.equals(ValuationEnum.FAIL)) { ... } and I get this error: WARNUNG: A BIRT exception occurred: Error evaluating Javascript expression. Script engine error: ReferenceError: "ValuationEnum" is not defined. (/report/method[@name="initialize"]#65) Script source: , line: 0, text: __bm_OPEN(). See next exception for more information.

(/report/method[@name="initialize"]#2) Note, that at least the first variant (importPackage) worked just fine with Eclipse 3.3 and BIRT 2.2.2. Now, with Eclipse 3.5 and BIRT 2.5.2 I cannot use my Enums anymore. For static functions, it worked to create instances of the class and use them to call static functions: importPackage( Packages.org.eclipse.core.runtime ); var reportdatamodel = Platform.getBundle("de.exam.reportdatamodel"); var projectHome = reportdatamodel.loadClass("de.micronova.exam.report.ProjectHome"); var inst = projectHome.newInstance(); var x = inst.getRootProject(session); Do I miss something there or has something changed here? Any idea what can be done? Cheers, Tim
