CTGraphicFrame Problem when creating a chart

[compactMetric]

Hi,

Thanks for writing pptx4j! It's great to be able to create full-featured powerpoint presentations from Java!

I'm trying to create a presentation with a chart on it. However, I am getting the following exception:

javax.xml.bind.MarshalException
- with linked exception:

Any ideas?

It works following http://dev.plutext.org/trac/docx4j/changeset/1468

Thanks for providing the sample with your post; that made this easy to fix.

Are you comfortable building from source, or would you like me to make a nightly build containing this patch?

cheers .. Jason

[compactMetric]

Thanks. I'll try to compile from source.

[compactMetric]

So I'm having trouble compiling from source. Could you jar-up a nightly build?

Thanks for your help!

[jason]

Please see http://dev.plutext.org/docx4j/docx4j-ni ... 110416.jar

What was the problem compiling from source?

[compactMetric]

Thanks.

I think I didn't configure Maven correctly. It would run without errors, but it wouldn't generate any .class files. Not a big deal though. Thanks for the nightly build.
