• Invalid string operation detected (*)! Please contact your software vendor to solve this problem!

       This error normally appears when for example you try to make an invalid operation in a string expression. For example you can not multiply 2 strings.

       The Designer parser will normally prevent you from doing this, except for "Condition" expressions like an "IF". In a condition there is no predefined type for the expression, so at run time, the expression will be assumed to be of the type of the first operand.
