Re: [docbook-apps] WebHelp bug?

[Stefan Hinz <stefan.hinz@oracle.com>]

Hi David,

Thanks for looking into this! Test case attached.

I should probably mention I'm using the 1.78.0 XSL style sheets, with a 
mildly modified webhelp/template/ folder (just a couple of images 
replaced with branded versions, such as logo and favicon).

Here again is the error I'm getting when trying to build WebHelp:

No template for "/book/chapter/mediaobject/imageobject/imagedata" (or 
any of its leaves) exists in the context named "title" in the "en" 
localization.
No template for "/book/chapter/mediaobject/imageobject" (or any of its 
leaves) exists in the context named "title" in the "en" localization.
XPath error : Invalid type
xmlXPathCompiledEval: 1 objects left on the stack.

Building the following formats works fine, though:

- HTML (one file)
- HTML (chunked per chapter)
- HTML (chunked per section)*
- XHTML (one file)
- XHTML (chunked per chapter)
- XHTML (chunked per section)*
- EPUB
- FO
- PDF

* Per-section chunking doesn't make sense for the little test case, but 
it works flawlessly, anyway.

Cheers,

Stefan
