SQLDeveloper 2.1.1 Oracle DB 10.2.0.4
Any existing tables are greyed out on the connections view under <schema><Tables>. Selecting the table gives a table tab on the right but it only has sub-tabs for columns, constraints, grants, statistics, triggers, dependencies, details, partitions, indexes - no data tab and no sql tab.
If I create a table logged in as that user and refresh the connections view, that table isn't greyed out and does have a data tab and an SQL tab.
If I then select one of the old tables so that it replaces the new table on the right - it now DOES have data and sql tabs. If I look at DBA_TABLES for old and new nothing obvious is different (apart from sizing info etc).
I'm a developer so I don't know too much about the inner workings of the database or what to look at. Any ideas?
