Rollover PJC - Unable to reference String within mouseadapter

Question

Hi
I am writing a PJC to colour the background of a text item on mouse rollover. The PJC extends VTextField and includes a nested mouseadapter class.
I would like a property, settable from the form, to determine whether the mouse rollover is enabled. The default behaviour should be rollover enabled.
To implement the behaviour of the property I have included a check on a string variable in the mouse adapter methods. If I don't set the property from the form the string is set to false. If I set the property using set_custom_property the string is set to the correct value.
How can I set the string to default to a value? It is declared as
String pEnabled = "YES";
I will post the full code
