Thank you for your post. I regret that the textual analysis is not supposed to be used in this way. I suggest you create a new candidate item for the renamed text.
thanks for your quick reply, I will say that at least the tool should guide the user, in a way or other, to follow the …right path/way only.
So VpUml should, at least, not let the user rename the Candidate Class (I’m not saying about the extracted text renaming), if it has no further sense/usage in the actual given way.
But you may also think from ICONIX perspective , at least as I understood , there is not only one way between the textual diag and use cases or other diags, you may want to further improve the used text (from textual diag) also for further usage (in usecase, robustness, sequence diags, docs).
