When customizing the dashboard, we save the layout in the DB so that a given user always has his last customized version of his dashboard. However (due to limitation in a param size in a URL?) this string is truncated at 256 chars. The DB field is TINYTEXT so shouldnt be limited here.
Todo: Build a shorter version of the customization string in order to save dashboards layout with 10+ widgets
A TEXT column with a maximum length of 255 (28 1) characters. The effective maximum length is less if the value contains multi-byte characters. Each TINYTEXT value is stored using a one-byte length prefix that indicates the number of bytes in the value.
Mindful, thanks for your careful review of my assumption ;-)
This is fixed in last version.
This week, the bug occur on my installation. I modify manualy the type of the column from TINYTEXT to TEXT. So it's ok for me.
But, I think it should be done in normal upgrade database process...
