Epub navPoints missing

Hi,

I am working with Alfresco Activiti that has Aspose Words 15.5.0. I am using Activiti/Aspose to build an epub document from html. I am able to successfully create an epub with table of contents, however the built in navigation points are missing for certain entries (but corresponding entries are correct in the TOC). In my document.ncx and the corresponding html files I am able to see the nav points, but as soon as I hit level 4 heading entries, there are no longer any nav points. So all level 1-3 nav points are working just fine, but it seems like level 4 nav points are not working (have not tried this with any levels after 4). Is there some limitation on the level that a nav point can be? Is this the intended behavior? Is there any way to add/delete nav points?

Thanks,
Monica

For the sake of any correction, we have logged this problem in our issue tracking system. The ID of this issue is WORDSNET-16782. We will further look into the details of this problem and will keep you updated on the status of this issue. We apologize for your inconvenience.

@mmaslowski,

Regarding WORDSNET-16782, we have completed the work on your issue and has come to a conclusion that this issue is actually not a bug in Aspose.Words. So, we will close this issue as ‘Not a Bug’. Please see the following details:

Depth of the Table of contents in .epub documents is controlled by the HtmlSaveOptions.EpubNavigationMapLevel property, and by default Aspose.Words exports only first three levels. You need to increase this value in order to get deeper navigation points included into the table of contents.

Works perfect, thank you. Although I do have another question, if I may.

There are only two changes I have made to the code I have provided earlier.

One is:
document.getBuiltInDocumentProperties().setTitle(“Title for EPub”);

And the second is that I am trying to use
htmlSaveOptions.setDocumentSplitCriteria(DocumentSplitCriteria.PAGE_BREAK);
OR
htmlSaveOptions.setDocumentSplitHeadingLevel(6);
htmlSaveOptions.setDocumentSplitCriteria(DocumentSplitCriteria.HEADING_PARAGRAPH);

The first split criteria is causing the epub to be malformed - if you click on the titles in the navigation panel, it does not go to the correct entry. Also the last navigation panel entry is incorrect.

The second split criteria results correctly, however, I do not want to split at every heading.

How can I split by page break correctly?
