[23:08] <bslivka> Woo hello[23:28] <zumbrunn> hi bslivka
[23:28] <bslivka> Great day
[23:29] <bslivka> I'm thinking I should probably post my little TestBug app to helma's bugzilla
[23:29] <bslivka> the behavior exibited just doesn't seem right.
[23:30] <zumbrunn> I didn't try out the TestBug.zip yet
[23:30] <zumbrunn> I'll try tomorrow morning
[23:30] <zumbrunn> (in a few hours)
[23:42] <zumbrunn> or nope... I'm trying right now...
[23:44] <zumbrunn> I see that main fails after the app is restarted
[23:44] <zumbrunn> but the object seems to be persisted
[23:44] <zumbrunn> calling add seems to add two nodes each time
[23:54] <bslivka> Yep
[23:55] <bslivka> if you look at the code, you'll see that I hava a mountpoint
[23:55] <bslivka> then another mountpoint on that mountpoint
[23:55] <bslivka> then a collection on that outer mountpoint
[23:56] <bslivka> add.hac adds an object to the outer collection
[23:56] <bslivka> which causes that object, and its parent, the outer mountpoint to be persisted
[23:56] <bslivka> but not the mountpoint's parent
[23:56] <bslivka> so the chain is broken
[23:57] <bslivka> in memory helma still knows what's connected to what, but since the inner mountpoint isn't persisted properly, it doesn't rebuild the graph correctly
[23:57] <bslivka> it starts from scratch
[23:57] <bslivka> that is, when you restart helma
[23:58] <bslivka> the workaround is to, one time, say root.homepage=new HomePage()
[23:58] <bslivka> which forces it to be persisted, and given a numbered id
[23:59] <bslivka> One thing I don't understand though is that unless you do that, the HomePage mountpoint's _id is "homepage"
[23:59] <bslivka> not a number
