Folks -

In fact Fabrik-related work will become my top priority as soon as we have modular projects working solidly.  Since there seems to be growing interest here, I will post a page on the swiki in the next couple of days outlining what it is, how it works, and some next steps for Fabrik in Squeak.  That should at least help people to try it out and, more importantly, allow us to identify some areas where cooperative endeavor might speed things along.

Please note that there are some code rot problems with Fabrik in 2.7.  Most of these were fixed in update #1855, so try to use 2.8a or at least fileIn #1855 if you want to play with it.

To build something from scratch, open a new ComponentLayout.  If you drop three text components in, and wire them together (use shift-click on a pin to draw out a wire), POOF, you have a tri-directional 'Hello World' example.  Type in any one of the textComponents, and type cmd-s for accept.

It should be possible to recreate the Browser example of PWM6 from scratch, but note that the top-left component is a printComponent.  Also, as Rick Thomas says, "you did a good job of hiding the 'add pin' option for functioncomponents.  It is on the halo menu alright but not reachable from the submorph option in the menu from a control click on the functionComponent."

Stay tuned

	- Dan
