How can a dashboard tab suddenly go "blank"

A tab has disappeared from one of my dashboard. It is "blank" now.

after investigation, I decided to I deleted it, then recreated it. Then I add the widgets to it. It all looked good for a few seconds but then, blank again.

No matter what I do, it keeps reappearing as blank.

See attached screenshot.

This is quite frustrating as the IT managers are using it to monitor tickets. The four widgets (reports ) I am adding to the tab in question can be found it the screenshot as well.

HA! HA! found the error!



DO NOT use quotes ( " ) in a report name and/or a tab name.



Don't know why but the tab is not visible.

Ah, awesome!   Thanks for finding the answer!   I'm surprised it would cause a problem, but I guess if it can't parse it for some reason it just gives up loading.  



I was going to say, the way the architecture is built for the reports is:



pa_dashboards


pa_m2m_dashboard_tabs


pa_tabs


sys_portal_page



So your top level dashboard you're looking at is an entry in the pa_dashboards table, then it's got a many-to-many table that links the dashboards to the tabs, and the tabs each contain a sys_portal_page.
