There are two ways to test for empty string, both using switch statements.

Method One

Code Block
<switch test="`$var1`">

This should be connected to two outcomes

Code Block
<outcome value=''>

and

Code Block
<outcome value='Other'>


Method Two

Code Block
<switch test="`length($var1) == 0`">

This should have true and or false outcomes attached

Code Block
<outcome value='true'>

and or

Code Block
<outcome value='false'>
