Description
I use FOP in a stand alone application (Eclipse RCP) for Export (PDF, PS) AND
Print (direct awt print) from the same fop-sources. One and the same FopFactory
is used per application run.
The AWT-Print renderer is set up by:
PrintRenderer renderer = new PrintRenderer(printerJob);
renderer.setUserAgent(userAgent);
userAgent.setRendererOverride(renderer);
Each transformation type (print or export) works for its own.
Doing an export followed by a print transformation (or the way around) of the
same source results in a NullPointerExeption for each Image. Please see the
stack trace below.
In other words:
If you start with an export you can always do a successfull export, but never an
awt-print.
If you start with an awt-print you can always do a successfull awt-print but
never an export.
Manually clearing the ImageCache solves the problem.
As the API of org.apache.fop.image.ImageFactory.clearCaches() points out, this
must be an issue.
The URLs does not change between the fop-runs.
Its protocol is OSGI-specific and shouldn't be the source
of the problem. Similar URLs work perfect in all other parts of the application
and with clearing the ImageCache too.
