Error with docx-importhtml bindings

[clueless_user]

Hi, wondering if you can help with a definite.. Me issue.

I'm running docx4j 11.4.6 and 11.4.7 under Java 11, build all appears to get well, but when performing a really, really basic binding I constantly hit the following stack trace and XHTML data is not being bound:

Code: Select all

I've tried here with just the demo for ContentControlsMergeXML281 and ContentControlsMergeXML. Unfortunately the hardcoded sample documents are missing so I've had to improvise, you can see the XHTML in the error, but the docx is invoice example (after failing with my own) cut down to a single XHTML field - truly minimal and not looking like a local office issue (was thinking my office 365 build might be the root). Same error for both examples.

Can you point me in the right direction or to any more documentation please?

This was:
docx4j-JAXB-MOXy if it makes a difference!

Not user error I'm afraid, at least not yours...

Here's a fix https://github.com/plutext/docx4j/commi ... 00b57aab86

I'll need to make a new release (though of course you could build your own from https://github.com/plutext/docx4j/tree/VERSION_11_4_8 if you want it quicker)

Thank you Jason, confirming the 11.4.8 snapshot works me, I'm sure I'll be back soon enough.

One last question though, is the Java 8 version a better choice if I'm not tied to this particular Java version - do you have a particular preference that leads the other releases or sees more active work?

Crawled the forums (and checked stack overflow) looking for clues on this and it's truly awe inspiring the effort you put into this software and the community and from what I can tell have done for at least 10 years. So again - thank you.

Thanks for your kind words.

Best to use the Java 11 version if it suits you; as it says at announces/docx4j-8-3-7-released-for-java-8-t3053.html

8.x is now a legacy branch; users are encouraged to migrate to v11.4 where active development is taking place.

An 11.4.8 release is now in Maven Central; release announcement to follow (along with -ImportXHTML 11.4.8).
