Argh, yeah, another namespace problem. Sorry you had to run into that. I do wonder though: is there no warning when you are (about to) overwrite an existing class ? And I would never name any class of mine anything general like Cache or Record without a namespace prefix. There should indeed be a CI job, I thought there was talk about a DBX one, but I can't find it. On 08 Apr 2014, at 22:34, Esteban A.

We might be better off renaming Cache to WeightedCache (or NeoCache or SystemCache). The class comment in Cache seems to cover more than what Cache actually does itself. Stephan

Hierarchical state machine implementation

by Johan Fabry

Hi all, I was wondering if there is an implementation of a hierarchical state machines (with input and output actions) available somewhere for Pharo. Any ideas?

Okay, I found the culprit: Glorp. If you execute this, it will load a class named Cache, which will overwrite Pharo's version. As happened with the referenced issue. Gofer it url: 'http://smalltalkhub.com/mc/DBXTalk/Glorp/main'; package: 'Glorp'; load. No one ever tried loading Glorp into a Pharo3 image? What do people use for ORM? Regards! Esteban A.

What are you loading ? There was a report back of some package overwriting system code leading to this error, I'll see if I can find it. On 08 Apr 2014, at 21:05, Esteban A.

Please check what is in your package cache. Any package where you have multiple versions? Stephan

I tried closing all windows, and just having a workspace. But the same happens even if I load the configuration through the command line. Screenshot attached. Esteban A.
