Can localization be used in a Mashup Expression?

[Timo697]

I often use the Expression function in mashups to display a modified version of a property of a Thing. 

For instance:

output = DeviceName + " Description";  //DeviceName is a String Parameter

I am trying to add localization to my mashups and would like to be able to use a token for the " Description" text.  How can I do this?.

@Timo697 You can try defining a session parameter with a default value as 'Description' and then that variable will be accessible in the mashups in the Session tab where you can bind it to your expression's input parameter.

What would I set the Base Type as?

I set it to String then wrote a localization token into the Default Value:    [[Test_Description]]

My code in the expression is now:

output = Device + " " + Description;

Now, the expression has an output of:    Device [[Test_Description]]
