I tried to go trough the tutorials and the moment I created a new file (ArticlePage) I run into problems with line endings in that file. (Also tried out Aptana Studio - and still cand find where to set the default line ending type)
The editor created a new file with mac line endings and soon as I tried to do db/build nothing happend. And after a while and many ways to hunt down the problem I stumbled upon the line endings. As soon as I converted them into unix or windows type all worked well.
If your code refuses to build and there should be no syntax on other errors and you're a developer on Mac try to convert the line endings.
Happy SilverSriping and coding
