I am encountering a strnage problem after designing my dashboard . Its not going in the preview mode .
As a preliminary analysis I found that deleting a tab() from my source file the XLF goes in preview mode . The tab just contains 500 rows , even if I delete the rows of the Tab and keep it as empty the XLF file does not goes in Preview mode . Only deleting the Tab() I can go into preview mode .
Any help why this strnage beahviour is occuring and how to diagnose the problem .
