SSIS Package variable changes type at run time

$
0
0

I have a package that I have just added a new variable to.   The new variable's scope is package-level, the type is string, and the initial value is empty.

Then I set the value of that variable at run-time with a script task.  

When I executed the package, it gave me an error that I was trying to change the data type of a variable which is not allowed.

I ran the package in the debugger, and when I put a watch on the new variable, it reported the datatype as Int32.   I look up and to the left, and in the Variables window, the type of that same variable is clearly "String".

Anybody ever had this happen?  I googled, and apparently I'm the first ever as far as I can tell.  I've tried giving the variable a default string value at design time, and still it changes the datatype of the variable to Int32 with a value of 0 when it runs.

Anybody else got any ideas for me?
