Fail to delete item from table view

[Johan Vallon-Christersson]

When in table view an item is marked (by check box). Selecting delete fails to delete item. When item is viewed separately (i.e. first opened) it can be deleted. Have observed this defect in Sample table and Raw bioassays table.

Any error messages? It works fine when I try it.

Replying to nicklas:

No error messages. Reproduced the problem in tables; Samples, Extracts, Labeled extracts, Lables, Hybridizations, and Scans. However, now it did work for Raw bioassays. When the problem occurs the page fail to refresh automatically. Does that provide any clue? Browser specific problem? I'm running Firefox 2.0.0.6 on Mac.

If the page doesn't refresh, there is probably some error somewhere. Please check the Tomcat log file and make sure that JavaScript errors are displayed. Ie. with Firefox open the window: Tools -> Error console.

This might be a problem due to very heavy load on mysql/tomcat during migration. Most of the RAM is eaten by the migration processes and maybe the server process gets affected. The tomcat log shows this message when the failure occurs:

We'll test again after the migration is finished. If the problem goes away we probably need to test single server machine under heavy load to see if we can reproduce the problem.

Seems to have been caused by Tomcat being overloaded.
