    I have experienced this problem also with older GGTS versions. It happens some times, I cannot deliberatly reproduce it but anyhow thought it's time for a bug report. I think it is similar to [GRECLIPSE-1175|http://jira.codehaus.org/browse/GRECLIPSE-1175] Today I was just using a Groovy SQL query: {code} Sql s = Sql.newInstance(...) def r = s.firstRow ("Select * from xxx") {code} In the course of fast typing r. attribute access code, I suddenly got an error popup claiming that some code completion did not work ... The editor window changed to a white canvas with a solid line and the word "Error". I could no longer save the file, it always claimed about an Exception (see below). I could only close the editor and left the file unsaved. However, in another window I had the file still open but could not open it again in a the original window but got an error message in some sort of a "error window", telling me "Failed to create the

The groovy code until the error occured looked similar to this: {code} def xyz = new Xyz ( id : r.id, author : r. filename : r.fn, ... ) {code} So I was just adding the value for the author attribute of Xyz. Maybe the Groovy classes got confused by the code around this point in the file?
