Hello Eclipse Community
I am looking for somebody who has some experience using the BIRT API and can help me.
I want to create a printable TOC with maintopic and subtopic like this
1. maintopic
1.2 subtopic
The API provides a lot of Objects to create a TOC but I just don´t get it how they are working together.
Another possibility to get a TOC is to use bookmnarks and to add them children this works fine on iText but in BIRT there is no way (so far as I know) to add children to a bookmark.
I posted this problem in other Forums too but no answer I am hopeing here is someone who knows about BIRT.
Is there any tutorial of how to use the API?
Thanks a lot
Dude

Attached is the modified class. It handles recursive toc entries now
and applies a little styling.
We are looking into adding something like this in the pdf emitter. Do
you see a need for a toc component for other output format?

Hi Dude,
Need some help, in this thread, you have stated that you faced this error :
Stacktrace:
java.lang.NullPointerException
at org.eclipse.birt.report.engine.api.impl.ReportEngine$EngineExtensionManager.<init>(ReportEngine.java:804)
And you were later able to fix it.Can you please let me know how you fixed this issue.
Thanks,
Amar.
