[jira] [Created] (DOXIA-662) Non unique IDs generated by IndexingSink

Konrad Windszus created DOXIA-662:
-------------------------------------

             Summary: Non unique IDs generated by IndexingSink
                 Key: DOXIA-662
                 URL: https://issues.apache.org/jira/browse/DOXIA-662
             Project: Maven Doxia
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0.0-M3
            Reporter: Konrad Windszus


If a HTML source contains non-unique headlines (i.e. two or more headlines with the same text) in a single HTML page the IDs being generated out of those are not unique.
That leads to issues with e.g. the TOC macro (https://github.com/apache/maven-doxia/blob/2aea4500ba6559b91fe3a4b83a5d3aafc10116b4/doxia-core/src/main/java/org/apache/maven/doxia/macro/toc/TocMacro.java#L155) which writes an anchor link leveraging that id.

The problematic line is https://github.com/apache/maven-doxia/blob/2aea4500ba6559b91fe3a4b83a5d3aafc10116b4/doxia-core/src/main/java/org/apache/maven/doxia/index/IndexingSink.java#L314 which just uses the (sanitized) title as id. In case of conflicts the title needs to be suffixed with an index to be unique.
