Resolution: Duplicate
> Using fo:retrieve-marker in an artifact (static content from header) breaks
> accesibility for the next page
> -----------------------------------------------------------------------------------------------------------
>
> Key: FOP-2959
> URL: https://issues.apache.org/jira/browse/FOP-2959
> Project: FOP
> Issue Type: Bug
> Components: renderer/pdf
> Affects Versions: 2.5, 2.4
> Reporter: Dan Caprioara
> Priority: Major
> Original Estimate: 1h
> Remaining Estimate: 1h

> Using a fo:retrieve-marker in a header static content, that is marked with
> role artifact breaks the accessibility tags structure tree for the next pages.
> {code:xml}
> <fo:static-content
> flow-name="sc-before"
> role="artifact">
> <fo:block>Header <fo:retrieve-marker
> retrieve-boundary="document"
> retrieve-class-name="title"
> retrieve-position="first-including-carryover"/></fo:block>
> </fo:static-content>
> {code}
> *The cause:*
> The class org.apache.fop.accessibility.fo.FO2StructureTreeConverter switches
> the current FOEventHandler (converter) to one that "swallows" all events each
> time an artifact is found, and restores the initial converter after the
> artifact ends.But this gets into conflict with the retrieve markers. The
> retrieve marker restore state event is processed asynchronous, just before
> the current page is finished, and restores the FOEventHandler to the one it
> was available when the start retrieve marker was emmited (in our case the
> "swallower", because the retrieve marker was in an artifact). The result is
> that the "swallower" is the current FOEventHandler for the next page.
> *The fix:*
> The fix is to restore the initial handler each time the page ends:
> At the end of the method:
> org.apache.fop.accessibility.fo.FO2StructureTreeConverter.endPageSequence(PageSequence)
> add:
> {code:java}
> if (converter == eventSwallower) {
> converter = structureTreeEventTrigger;
> converters.clear();
> }
> {code}
