State of Slots

by Peter UhnÃ¡k

Hi, what is the current state of slots? I found a message by Marcus that it's not ready but that was December; has anything changed? Is there some tutorial/examples? Are there known problems? Thanks, Peter

Your experience building a CRUD framework using Magritte and Bootstrap was very similar to mine. My stuff is on a back burner for now, but I hope to get back to it sometime soon. I hope Quuve is successful for you guys.

Re: [Pharo-users] JavaLoader

by Blaine Buxton

I updated the java loader library to Pharo 4 (load the latest from smalltalkhub.com) There was a few bugs and deprecated methods, but I fixed them all. I loaded a new Java 8 class (with lambdas) and everything is working. If you have a problem, could you send me the offending class to self(a)blainebuxton.com? There's a lot of moving parts and I would like to start adding tests for what fails.
