[Pharo-dev] self item returns a string

[Stéphane Ducasse]

Hi ben

Im trying to fix the problem of the finder putting too many string around the 
arguments.
if you type 'a' . 'b' . 'ab' and example
you will get '''a''' . '''b''' 

so I found that 

displayString

        self halt.
        ^ self item asString

self item returns a byteString and item is not redefined in FinderNode

I tried to change it to 

displayString


        ^ self item 

but self item is already '''a ''''

the item on the node is already a '''a''''….

So I tried to check how the node were populated but I could not get 
childrenItems to work.
