I get syntax errors in Visual Studio when writing DAX expressions. VS suggests separating parameters with semicolon and not commas ex. CALCULATE(Expression; [Filter1]; [Filter2]; ...).
When writing expressions with commas I get syntax right away but when writing them with semicolons they process once but if I try to run the calculation again if fails with a syntax error message. I have tried this on two workstations. I use VS 2010 SP1. Tried whis on both a Windows 8 PC and a terminal server running Windows Server 2008 R2.
Any suggestions or known bugs?
