https://forum.world.st/I-think-I-ve-discovered-an-error-in-the-later-v9-builds-tp5119226.html
(Overall, this error does not occur in v8 - even the latest snapshot.1140. It did not exist in the v9 image from February - I don't know how to tell what build it is. But the latest Official Distribution for v9 and the latest snapshot.840 - the following error occurs:).
This error appears to be around the transmitTo: within SpPresenterWithModel>>connectPresenters. I haven't been able to (yet) trace why, but the debug message is in the 2nd 'transform:' below -- erroring saying that 'each' is nil - and doesn't understand the #method2 message.
Here is the scenario:
(aSpTablePresenter(1) transmitTo: aSpTablePresenter(2))
transform: [ :each | ((each #method asOrderedCollection ) sorted: #title ascending ) ].
"transmit aSpTablePresenter(2) to aSpTablePresenter(3)"
(aSpTablePresenter(2) transmitTo: aSpTablePresenter(3))
transform: [ :each | ((each #method2 asOrderedCollection) sorted: #number ascending )].
The UI populates just fine - when I click a row in the first aSpTablePresenter(1) - it fills the 2nd aSpTablePresenter(2), but it looks like the code above attempts to do the 2nd transmitTo: to populate aSpTablePresenter(3) and is trying to do so without data from aSpTablePresenter(2) - there could be a number of reasons for this.
Behavior-wise, I would prefer that SpTablePresenters default to a first row selected and populate (transmitTo:) to each of their SpTablePresenters in kind (defaulting to first row, then transmitTo: the next tablePresenter).
Through the Inspector, all three SpTablePresenters have their lists populated - and the UI shows these lists - even after punching through error.
Another observable - when I click on column headers to sort, the transmitTo:'s get called again and also error out - even the first transmitTo:... could be one simple change will correct all these anomalies.
I will try and mock-up a simpler version to share. Please let me know if you have any questions or items I should specifically include.
Thanks!
