Angelo, Chuck, et al., There is a bug in Eclipse 4.3 where you cannot select entities, attributes or relationships in the right-hand pane because it does NOT update the Properties tab, so it is very easy to think you are editing one thing but in-fact be editing something else. You MUST select everything in the Outline tab.
Also, in both 3.7 and 4.3 EntityModeler does *not* watch for changes to any of the .eomodeld packages that it has open. This causes EM to be out-of-sync with the file system under *at least* the following conditions: 1) Manually editing any of the .eomodeld files with a text editor 2) Having more than one EntityModeler perspective or tab open at once - which WOLips does by default when you cmd-shift-v open an Entity or Model, even if they are already open (maybe this can be fixed by setting the preference to “reuse” an editor, I haven’t checked) 3) Pulling/merging/etc changes from a source code repository 4) Full moons (not in the celestial sense) Over time EntityModeler has become what EOModeler / WOBuilder used to be: Awesome tools that are amazingly helpful, but have bugs that require a lot of routine work-arounds that new/occasional users will not know about or remember. I’ve looked into trying to fix some of these bugs in EntityModeler, but Eclipse plugin development is … well … not-so-WOish. I’ll try to get to documenting some of these things in the WOLips issues: https://github.com/wocommunity/wolips/issues Dave On Mar 24, 2014, at 3:43 PM, Ângelo Andrade Cirino <[email protected]> wrote: > Unfortunately it happens.
