> URL: https://issues.apache.org/jira/browse/PDFBOX-4496
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.14
> Reporter: Stefan Ziel
> Priority: Major
> Labels: OCGs
> Attachments: PDFBOX-4496.patch, original.pdf

>
> The class {noformat}
> org.apache.pdfbox.pdmodel.graphics.optionalcontent.PDOptionalContentProperties
> {noformat}
> contains two methods
> {noformat} setGroupEnabled(String, boolean){noformat} and {noformat}
> isGroupEnabled(String){noformat}
> accessing the OCG's state using a name as parameter.
> As there can exist various OCG with the same name this access is not well
> defined.
> The current implementation accesses the first group with this name it can
> find.
> To make setter work the solution would be a loop over all groups with the
> given name and add them to the ON or OFF.
> The getter should return an error state if the instances diverge in state.
