of course, now I remember :)

Use xrcTextCtrl.Label instead of .Value.

The Value property is indeed an accessor. I don't know if it is possible 
to pass an accessor using explicit rules. If it is, it should be

make_expr<accessor>("xrcList.Current.Info")

and make_expr should 'cast' the string to an accessor implicitly. Or 
something like this. Your expression above tried to make an accessor for 
the expression, which will not work.


wxTextCtrl has three properties that can be used for the actual text:

Value is of type accessor and automatically detects the correct type.
Double is of type double.
Label is of type string.

So for double variables you'd use

xrcTextCtrl.Double = m_myDouble

for string you'd use

xrcTextCtrl.Label = m_myString

I choose label because it is inherited by all controls.


The Value property comes in handy when you are using implicit rules 
where your data variable and text ctrl name are the same. RapidUI will 
create the rule automatically.
