I was chancing my local sql-database data sources to tableau server data sources and all that went well.
But when I did take a look on my dashboard, all the icons that had shapes had lost it formation and icon that was assigned to it.
Well, no problem, been there before. I was going to replace the misformated icons, but wait, there is no icons?!
Only two sets of basic icons were present on the icons menu. How can this be possible?
I closed all the Tableau workbooks and opened it again and it worked normally. I did see all the shapes again and the shapes were right on the dashboard automatically.
may be it is search index problem in the server side i guess.
