Possible Bug in 2.2 when processing extended content in LocalizedContentVisitor [message #254043]

Hi,

The problem I'm running into at the moment appears to be a bug at
org.eclipse.birt.report.engine.presentation.LocalizedContent Visitor
protected IContent processExtendedContent(IForeignContent content)

I've written a custom report item and I want it to be able to be used
within a table but also by itself.

And it pretty much works, except for the situation when the item ISN'T
embedded in a table but there IS a table in the report.

It seems that some new code in the LocalizedContentVisitor is trying to
create a SingleRowSet, but the result set it's trying to use is invalid
(and is sometimes even null).

At line 671

rowSets[0] = new SingleRowSet( context,
(IQueryResultSet) rsets[0] );

bombs out with

java.lang.NullPointerException
at
org.eclipse.birt.data.engine.impl.ResultIterator.getResultMe taData(ResultIterator.java:754)
at
org.eclipse.birt.report.engine.data.dte.QueryResultSet.getRe sultMetaData(QueryResultSet.java:367)
at
org.eclipse.birt.report.engine.extension.internal.RowSet.<init >(RowSet.java:57)

org.eclipse.birt.report.engine.extension.internal.SingleRowS et. <init>(SingleRowSet.java:23)

at
org.eclipse.birt.report.engine.content.impl.ForeignContent.a ccept(ForeignContent.java:59)

I'm not sure why it's trying to create a row set at all, since the item
isn't embedded in the row set or associated with it in anyway.

An expansion of my understanding is more that welcome, but this seems like
a bug to me.

Cheers,
Shaun

Below is the fix that I have implemented, in case anyone is interested.
Sorry it's just a CVS diff from BIRT_2_2_0_Branch, but hopefully that
should be enough, I'm not sure what the correct procedure for submitting
these is.

Are are the actual updates also

org.eclipse.birt.data.engine.impl.ResultIterator

public IResultMetaData getResultMetaData( ) throws DataException
{
try
{
if ( odiResult != null )
{
return new ResultMetaData( odiResult.getResultClass( ) );
}
else
{
return null;
}
}
finally
{
logger.logp( Level.FINE,
ResultIterator.class.getName( ),
"getResultMetaData",
"Returns the result metadata" );
}
}

org.eclipse.birt.report.engine.data.dte.QueryResultSet

public IResultMetaData getResultMetaData( ) throws BirtException
{
if ( null == rs )
return emptyResultMetaData;
else {
IResultMetaData md = rs.getResultMetaData();
if ( md == null ) {
return emptyResultMetaData;
} else {
return rs.getResultMetaData( );
}
}
}

org.eclipse.birt.report.engine.presentation.LocalizedContent Viewer

if ( queries != null )
{
if ( rsets != null )
{
rowSets = new IRowSet[rsets.length];
for ( int i = 0; i < rowSets.length; i++ )
{
rowSets[i] = new RowSet( context,
(IQueryResultSet) rsets[i] );
}
}
}
else
{
if ( rsets != null && rsets[0] != null )
{
rowSets = new IRowSet[1];
rowSets[0] = new SingleRowSet( context,
(IQueryResultSet) rsets[0] );
}
}

Got my act together and created a bug report for this, bug #203031, and
it's already fixed! released in 2.2.1, great stuff.
