Thanks Chipp. That works if the custom prop is an array to start with, but my
question is whether it is possible to access all kinds of custom property data
in the default custom property set using array notation. Here's the situation:
I have an image object that has several different visual states. The state is
represented by image data stored in custom properties of the image, labeled
like this:
state1
state2
state3
state4
When I want to change visual states I simply set the image text to one of the
custom properties. It would be much easier to do if I could do something like
this:
set the text of img "myImg" to the customKeys["state" & currStateNum] of img
"myImg"
Instead, I have to construct clumsy "do" statements to make the changes.
Unfortunately this doesn't work when using properties in the default set. It
does work when you have created the properties in your own sets:
set the text of img "myImg" to the myPropSet["state" & currStateNum] of img
"myImg"
(From memory, so I may be missing a detail of the syntax.)
So the question is, can you access non-array data in custom props using array
syntax when using just the default property set?
