When working with object data types and doing a value comparison on a property, it is a good idea to verify the type before doing the value comparison. In the example below, “myMethod” checks if an input object’s “foo” property is “bar”:

// myMethod #DECLARE($obj : Object) If ($obj.foo="bar")    ALERT("Does equal.") Else    ALERT("Does not equal.") End if

If “myMethod” is called with an object that has “foo” assigned to value 1 (integer), an error will be thrown.

$obj:={foo: 1} myMethod($obj) // error

Instead, wrap the code in a Value type check before proceeding with the value comparison:

// myMethod #DECLARE($obj : Object) If (Value type($obj.foo)=Is text)    If ($obj.foo="bar")      ALERT("Does equal.")    Else      ALERT("Does not equal.")    End if Else    ALERT("Wrong type.") End if

This way, the error can be caught gracefully.
