Found another quirk with OBIEE 10g today that I thought I would share.
I opened up one of the reports I have been working on and clicked a navigation link. The nav link goes to a page that contains two reports. Each of the reports sits within a section that contains guided navigation. Well, when I clicked the link to navigate, I was greeted by an empty page. My session log showed that neither report had run and I wasn’t greeted by the typical “Guided navigation is loading” or whatever it says.
Well, turns out that a field that is used in the reports was changed (name change without alias) and broke the report. Typically we would see an error, but in this case, because OBIEE never even ran the report it didn’t show up in the session logs. So if you ever run into a situation where your guided navigation isn’t running and you don’t know why, check to ensure that your guided nav report contains correctly mapped fields.
