Hi, I'm migrating my grafoscopio interface from I'm trying to capture some changes in a text morph that is part of a Spec interface. The interface is split in 4 parts, as you can see at [a]: (1) a main menu, (2) a tree, (3) a node header input text and (4) a text morph. When you click any node on the tree (2) the name of the node, called the header is shown in (3) and the node contents, called the body are shown at (4). If you made a change in the header (pressing enter) it's reflected back to the main tree. And the node's body is changed for a text morph [b] or a and embedded playground [c] according to tags in the node. So the reading part is working and I have some partial support for persistence, at least for node headers. [a] https://offray.withknown.com/2016/grafoscopio-notebook-interface [b] https://offray.withknown.com/2016/grafoscopio-text-node [c] https://offray.withknown.com/2016/grafoscopio-code-node Now I would like to extend the persistence for node's body content, so when any changes happens in the (4) panel, be it a text panel or a playground, it is stored in a similar way to what is happening with node headers and the (3) panel, but I'm unsuccessful trying to capture those changes. My initializeWidgets and initializePresenter are implemented this way: ================= GrafoscopioNotebook>>initializeWidgets windowMainMenu := self newWindowMainMenu. tree := TreeModel new. body := self newText. header := self newTextInput. body disable. body text: '<-- Select a node in the left panel'. tree childrenBlock: [:node | node children]; displayBlock: [:node | node title ]. ================= initializePresenter tree whenSelectedItemsChanged: [ :arg | arg isEmpty ifFalse: [self changeBody: arg ]]. header whenTextChanged: [ :arg | Transcript show: arg. (tree selectedItem content header) = arg ifFalse: [ (tree selectedItem) content header: arg. tree roots: tree roots]]. body whenTextIsAccepted: [ :arg | Transcript show: arg ] ================= I'm capturing properly the changes in text with whenTextChanged on the header but using the same message on body or whenTextIsAccepted doesn't produce any change on the trascript, and of course I can't update the any tree/node contents properly. Any advice on how to solve this will be greatly appreciated. If can happen soon in this week even better, because we could show this to our hackathon/workshop attendees. Cheers, Offray
