Editor showing "Error" after build command change

[pawelwod]

When e.g. build parameters changes the content in editor pane is disappearing and instead I see "Error". In all opened editors is same issue. Need to close all editors and reopen them. Can this be refreshed automatically?

Don't want to start new issue if it is already fixed so asking first here in discussion. Pls close if it is fixed.
