Hello, I had a problem with updates of css files in Pier (using the pharo-1.0-10491-rc1web09.10.5 image). My updates were ignored. After some debugging I found out that the the cause of the problem was that two different MAExternalFileModel instances compared equal. They were both called 'style.css' but they had a different location. The location was not checked in the equals method. After adding the following equals method to MAExternalFileMethod everything worked fine: = anObject     ^super = anObject and: [ self location = anObject location ] Greetings, Jan. _______________________________________________ Magritte, Pier and Related Tools ... https://www.iam.unibe.ch/mailman/listinfo/smallwiki
