It's runtime error.
may be only in Pl/SQL Developer

PL/SQL Developer
Version 10.0.1.1694

Windows 7 (64-bit) 6.1 Build 7601 (Service Pack 1)

There is no error in "Sql Editor".

Error appears while mouse is over sql block, when i click on table name or function name

I have submitted this issue as new ticket, ticket tracking code #SA0027744

We have found that this issue is actually caused by what we believe is a bug in PL/SQL Developer, and notified them about it. Hope they will fix it in the next release.
