I have a static variable in my itcl class 

public common x  {};

Whenever I am trying to access the variable using info exists x ($key), I get an error variable isn't array.

Am I missing something here?

    I am not familiar with itcl, but supposing normal Tcl rules still apply, once you've assigned a value to a variable, you can't access it using array syntax. If `x` is an array variable, you can use the syntax `x($key)` to check for existence, assign values, or retrieve values. But if you have assigned a value like `{}` to `x`, it can't be used as an array variable. – Peter Lewerin Nov 24 '17 at 22:37

  • @PeterLewerin , You are right the initialization of the variable was wrong . – wthomas Nov 28 '17 at 11:12
