How to get folder of checked out part?

Hi.

I need to put created child parts to the parent part folder (all i do through java code).

If parent part wasn't checked out, then folder is defined corrrectly ( for example: wt.folder.Cabinet:103501<Default>) by code FolderHelper.service.getFolder((FolderEntry) parentPart).

But if parent part was checked out then FolderHelper.service.getFolder method returns something like that: wt.folder.SubFolder:48744<Checked Out>.

How can i get first result of checked out part?

Thanks.
