Property Expansion in Rule Conditions

Property Expansion in Rule Conditions

Rules for property expansion in business rule conditions:

The right hand side can be a literal value.
The right hand side can be a property (indicated by wrapping in square brackets).
The left hand side is always considered a property (which gets expanded using the path of the rule property). If the property is not found, it will be interpreted as an empty string.

For example:

Property	Operator	Value	Comments
Site Name	starts with	Dovetail Software	The condition evaluator will expand the property "Site Name" to its actual value, and compare it to the literal string "Dovetail Software".
Site Name	starts with	[My Property]	The condition evaluator will expand the property "Site Name" to its actual value, then expand the property "My Property" to its actual value, and compare the two. If "My Property" is not defined as a property, then the Site Name property will be compared to the literal string "[My Property]" (including the square brackets).
Unknown Property	starts with	foo bar	The condition evaluator will expand the property "Unknown Property" to its actual value, and compare it to the literal string "foo bar". If "Unknown Property" is not defined as a property, then it will expand to an empty string, and the empty string will be compared to the literal string "foo bar".
