Re: [Factor-talk] Model activation sequence
Hi Mark, I'm basing my remarks on https://github.com/hyphz/fr8x-editor/tree/257e244c3a20175a5c88d8c2f776999897025776 Like you said, for the arrow to work, it needs to be activated. In your program the activation of the arrow is done by the open-window which calls the graft method of the checkbox holding your partmodel. So I guess you should move your code around to not depend on the data of the arrow until all the models have been activated. Maybe you can just remove the call to partmodel-fetch in new-partmodel, are they really needed ? The ui starts fines without them.

Re: [Factor-talk] Model activation sequence
Actually, the call to activate-model is just before the call to the gadget's graft* method, but the point remains the same Jon On Sat, Jan 3, 2015 at 8:02 PM, Jon Harper jon.harpe...@gmail.com wrote: Hi Mark, I'm basing my remarks on https://github.com/hyphz/fr8x-editor/tree/257e244c3a20175a5c88d8c2f776999897025776 Like you said, for the arrow to work, it needs to be activated.

Re: [Factor-talk] Dealing with parts of a model
Hi Mark, model-field can't work with arrows. Among other reasons, in your case the arrow is not activated when it's data is used to intialize the editor string (that's why you see them empty). The model given to model-field isn't meant to be updated by the caller anyway: it's value is used as an initialization of the editor-string, but after that only the editor-gadget should update the input model when the field is edited. Maybe you should think of your problem the other way around: instead of having data in your structure and creating arrows from pieces of it, wrap all the data in your structure in models and pass those models to the UI ? The UI will then update your structure when the user edits fields.

I'm still struggling a bit with how to create a UI that alters parts of a structure. So far I can store the structure as a whole in the model slot of the containing pane, and I can create arrow models for the individual controls to refer to. The problem is writing changes back again, since the arrow model does not propagate changes back across itself. I see there is a double-ended arrow model in extra called illusion, but it seems to depend on the arrow operation being invertible which extraction of part of a sequence (for example) is not. It is however mergable in that the data from the lower level model could be re-incorporated into the higher level model given knowledge of them both. Does anything support this? Also, does model-field work correctly? When I try to create one, it seems to come up blank and editable, even if the arrow model contains data and is not writable.
