FMPS does not seem to be processing index terms correctly.
When the index terms are placed in the prolog, a blank link is generated in the PDF output that appears above the topic title.
When the index terms are embedded within the text, the indexterms are processed like a carriage return was placed in the middle of a sentence.
When index terms are entered as <indexterm>entry<indexterm>entry2</indexterm></indexterm>, nothing is generated in the index and also the above (blank lines in the PDF output).
I know. AEM Guides v4.2 would eliminate all the FMPS issues. We're still trying to get it installed and working correctly on the test server before upgrading production.
