Problem using Java Enums with BIRT 2.5.2

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 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: 
<pre class='_prettyXprint _lang-auto _linenums:0'>
importPackage(Packages.de.micronova.exam.report.enumeration);
if (x.equals(ValuationEnum.FAIL)) {
...
}
</pre>
 
and I get this error: 
<pre class='_prettyXprint _lang-auto _linenums:0'>

Importing the enum with inportClass does not work as well: 
<pre class='_prettyXprint _lang-auto _linenums:0'>
importClass(Packages.de.micronova.exam.report.enumeration.ValuationEnum);
if (x.equals(ValuationEnum.FAIL)) {
...
}
</pre>
 
gets me this: 
<pre class='_prettyXprint _lang-auto _linenums:0'>
Function importClass must be called with a class; had "[JavaPackage de.micronova.exam.report.enumeration.ValuationEnum]" instead. (/report/method[@name="initialize"]#2)
</pre>
 
Note, that at least the first variant 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. 
Do I miss something there or has something changed here? 
Any idea what can be done? 
 
Cheers, 
Tim 
 
EDIT: 
I just noticed that it does not work to access static functions in a static way as well: 
<pre class='_prettyXprint _lang-auto _linenums:0'>
importPackage(Packages.de.micronova.exam.report);
var x = ProjectHome.getRootProject(session);
</pre>
gives the same error as above. 
The only workaround I have found is this: 
<pre class='_prettyXprint _lang-auto _linenums:0'>
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);
</pre>
 
This is a hack and does not work for enums - any suggestions?

I have not heard of anyone else having this issue, but if this worked in 2.2.2 and no longer does in 2.5.2, please file a bug for it at http://www.birt-exchange.org/org/resources/bug-reporting/ and see if they have a workaround for it. You might try downloading 2.6.x and see if it works for you in the newest version.

Thanks for your quick reply. I filed a bug at https://bugs.eclipse.org/bugs/show_bug.cgi?id=328094
Unfortunately, upgrading to 2.6.x is not an option because we already delivered a product with Eclipse 3.5/BIRT 2.5.2 and we must stay compatible with that for the time being.

Cheers,
Tim
