stateflow action language if else construct

My question deals with the action language used by Stateflow :

when I use something like

during:
if (i==2)
  x = 1;

I got an execution saying : Unresolved function 'if' in ...

It seems that if/else constructs are not supported

Is that true ?

(I am using R2010a)

You can see that you can do it with R2010b
