String type variables losing the char returns and losing data. Bug?

I have found a bit of a quirk in the SSAS DDL task and wonder if anyone had come across anything similar.

I want it to an MDX script from a variable so the SourceType is Var and the source is User::DimMDXSource.

When I paste the script into the value of the var, it only stores the first line because it doesn't seem to store the char returns.

I have tried storing it as an expression but it won't evaluate it as an expression, assumingly because the script contains double quotes.

The weird thing is, I have another package where I did this and it put the square char returns in upon pasting and actually stores the whole script in the variable value. I copied the package (so I know the settings are fine) but again, when I paste the script it, it only stores the first line. It's quite bizzare.

I don't really want to do this as a config package file. How on earth did I get it to work in the first place? Is it to do with some encoding setting somewhere?

Anyone know a work around?

Thanks
