For this kind of situation, my solution is to use a valueHolder
instead of storing your string directly in an inst var, store it into the value
holder
initialize
string := '' asValueHolder
string: aString
string contents: aString
string
^ string contents
And then what you can do in your initialise is
string whenChangedDo: [:newValue | self label contents: newValue ]
Something like this should work ^^
The other solution (which is baaad, but can still be seen) is to have a step
method refreshing the Morph.
But this is really not efficient
Hope it helps,
Ben
