BIRT + XML Parser (Xerces)

[kevinroll]

Our application uses the BIRT 2.5.0 runtime engine to generate a variety of reports. This has been working well for quite a long time. Due to a completely unrelated requirement I added the Xerces XML parser to our classpath (xercesImpl-2.6.1.jar). This caused the BIRT engine to begin to fail with a strange exception:

09/07/01 13:45:50:819 WARN reporting.BirtManager: Exception generating report element (Community Profile):
java.lang.NullPointerException

at org.eclipse.birt.report.model.parser.ModuleParserHandler.endDocument(ModuleParserHandler.java:393)
at org.apache.xerces.parsers.AbstractSAXParser.endDocument(Unknown Source)

The code in question is simply looking for some flag in the XML:

private void doCompatibility( Chart cm )
{
// we use the base series' format specifier for category legend
// before.
// for compatibility after the fix of #237578
if ( cm.getLegend( ).getItemType( ) == LegendItemType.CATEGORIES_LITERAL )

I'm assuming that when I added the parser BIRT began to use it, and somehow there is a difference in how the XML is being parsed. How can I get these two to coexist?

Hi,
I'm having the same problem... did you manage a way to resolve this issue?
Thanks
