CHM conversion issue because of indexterm

[susannecm]

Hi,

I am trying to migrate some transformation scenarios from DITA OT 1.7 to DITA OT 2.*. The PDF conversion is working, but the CHM conversion doesn't.
I have a huge bookmap that can be converted to PDF and to Webhelp und to CHM using DITA OT 1.7 and our custom adjustments.
However, both the internal DITA OT and an external DITA OT 2.5.4 produce the same error:

Code: Select all

dita.map.htmlhelp.hhk:

Could this be a problem with index-see and index-see-also and if so, how do I get rid of it?

Thanks for any help

Hi Susanne,

I managed to add some logging in the DITA OT code and reproduced the problem, I added an issue for it on the DITA OT issues list:

https://github.com/dita-ot/dita-ot/issues/2920

The problem is somehow related to using indexterm with index-see either directly in the DITA Map or on a DITA topic inside the <title> or <shortdesc> element.
If you contact us via email (support@oxygenxml.com) I could try to provide you with a patched JAR library for your used DITA OT 2.5.4 distribution.

Regards,
Radu

Hi,

Just to update this forum thread, we released Oxygen 20.1 and its bundled DITA OT 2.x publishing engine should have this problem fixed.
