cell server and @interact: button not always working

[Dan Drake]

I made a nice @interact, but one of the buttons isn't working. See
http://aleph.sagemath.org/?q=ab8e07c5-5ef6-4c1d-a9eb-e99f6364a38a or the
monster URL below.

The problem is, I can't hit "Next" twice in a row. If I do "prev" or
"zoom", then "next" works properly, otherwise it just doesn't respond.

I've tested this on Firefox, Chromium, and IE 9. All give the same
behavior. This works properly in the notebook (version 4.8).

Any ideas?

Dan

We've made the distinction between a selector having buttons and a
button bar initiating action at button presses. A selector selects an
option (so selecting the same option is a no-op, and the selection
should be highlighted). A button bar has, well, a bar of buttons, each
of which initiates an action. If you change your line:

step = ['Next', 'Prev', 'Zoom', 'Reset']

into

step = ButtonBar(['Next', 'Prev', 'Zoom', 'Reset'])

then it works well.

Is this incompatibility likely to hurt lots of people?

Thanks,

Jason

I don't mind that, but it's not the same as Sage @interacts, right? I
would prefer that they work the same in the Sage notebook and in the
cell server. What are the synchronization plans?

You're right. The current sagenb.org interacts confuse selectors with
button bars.

We plan to port our implementation back to Sage this summer.

Thanks,
