[Pharo-users] RewriteTool matching parts of an array

Hi, I wanted to use RewriteTool to rewrite dynamic arrays Source AST: | base | base := {#Department -> {710 @ 255. Color lightMagenta}} matching AST: | base | base := {#Department -> {``@first. ``@second}} transformation: | base | base := {#Department -> (Array with: ``@first with: ``@second)} However when I tried to execute it I was met with DNU OrderedCollection>>parent: It seems that the @first/@second part are not matched properly. Any way to fix this? Or am I doing it wrong? Thanks, Peter
