I've upgraded a mango installation from 1.2.3 to 1.4.0 and then to 1.4.1.
When I load up the data source edit page for a modbus_ip datasource it shows the update period as 15 seconds instead of 15 minutes. If I save it as 15 minutes, and then reload the page it still shows 15 seconds. However the update period must be saved correctly as the source is only updated every 15 minutes. When I view source on the select box there is no SELECTED attribute on any of the option tags.
This problem is not confined to the datasource edit page. I've observed the same behaviour while switching points over to interval logging.
I do not have this problem on a fresh 1.4.1 installation.
I created a new datasource on the upgraded 1.4.1 installation and was unable to set the update period properly on the new ds, so the problem isn't confined to pre-existing datasources either.
Can I delete and re-install the webapps/ROOT directory or is there some way of investigating how the upgrade is botched? I have remote access to the server and eclipse is installed so remote debugging is an option.
