12:58:16 <trackbot> Meeting: XForms Users Community Group Teleconference
12:58:17 <trackbot> Date: 16 March 2016
12:58:48 <Steven> Agenda: https://lists.w3.org/Archives/Public/public-xformsusers/2016Mar/0008
12:58:56 <Steven> Steven has changed the topic to: Agenda: https://lists.w3.org/Archives/Public/public-xformsusers/2016Mar/0008
12:58:58 <Steven> Chair: Steven
13:00:43 <Steven> Present: Alain, Philip, Steven, Erik
13:02:26 <ebruchez> I think I forgot the new password
13:03:09 <Steven> Topic: ACTION-2056 - Summarise compute-exception problem, with an eye to finding a solution
13:03:09 <Steven> https://lists.w3.org/Archives/Public/public-xformsusers/2016Mar/0007.html
13:06:10 <Steven> Steven: A binding contraint error was for instance when two constraints were bound simultaneously
13:06:16 <Steven> Erik: Which is now allowed
13:06:58 <Steven> Erik: I think we can solve this simply
13:07:09 <Steven> ... using an event instead of an exception
13:07:41 <Steven> ... and giving up on a recalc seems like the simplest thing to do.
13:08:22 <Steven> ... of course the form may not work, but if the author caught it, he or she at least did it deliberately
13:08:40 <Steven> Steven: Does anyone actually check for circularity?
13:09:32 <Steven> Alain: XSLTForms does
13:09:37 <Steven> Erik: Not sure what we do.
13:09:55 <Steven> Steven: What do you do in response?
13:10:00 <Steven> Alain: I'd have to check.
13:10:41 <Steven> Steven: What do you think og Erik's proposal?
13:10:45 <Steven> Alain: I prefer it.
13:11:03 <Steven> Erik: It is good to get rid of the fatal exceptions. And it is not a huge deal.
13:11:11 <Steven> Steven: So we just go with it?
13:11:20 <Steven> Erik: Sounds good.
13:11:38 <Steven> ACTION: Erik to write spectext for replacement of compute-exception
13:11:39 <trackbot> Created ACTION-2057 - Write spectext for replacement of compute-exception [on Erik Bruchez - due 2016-03-23].
13:12:42 <ebruchez> https://www.w3.org/community/xformsusers/wiki/XForms_2.0#Extension_Functions
13:13:17 <Steven> Erik: One more aspect is the functions attribute on the model element
13:14:00 <Steven> https://www.w3.org/MarkUp/Forms/wiki/XForms_2.0#Extension_Functions
13:14:28 <Steven> Erik: Also dispatches compute-exception
13:14:47 <Steven> ... I propose replacing that with the error as well
13:14:53 <Steven> ... I didn't mention it in the mail
13:15:24 <Steven> Alain: I implement that, and have no problem with the error solution
13:15:46 <Steven> Topic: ACTION-2051 - Experiment with a type for non-space string, and
13:15:46 <Steven> report back
13:15:46 <Steven> http://www.w3.org/2016/02/17-forms-minutes.html#action02
13:16:24 <Steven> Steven: Better link is https://www.w3.org/2016/02/24-forms-minutes.html#item02
13:17:23 <Steven> Steven: I think we had the solution of either to do it with a type, or with a MIP
13:17:39 <Steven> ... the advantage of a MIP being that it would work across lots of other types as well
13:19:53 <Steven> Erik: We talked about a general solution, and transforming values between data and controls, but there are benefits to handle the whitespace issue specifically.
13:20:53 <Steven> ... using an XPath function would be a bit heavy.
13:21:42 <Steven> ... also there are questions of whether to put it on the control or on the data
13:21:50 <Steven> ... we think it is better at the model
13:22:23 <Steven> ... all controls will work identically
13:22:41 <Steven> Steven: So the MIP is the better solution
13:22:45 <Steven> Erik: I see benefits
13:23:04 <Steven> ... but we don't have a lot of experience.
13:24:46 <Steven> Steven: So we would have a MIP <bind ref="x" whitespace="preserve|trim|remove|normalise"/>
13:25:01 <Steven> ... preserve = do nothing
13:25:09 <Steven> ... trim= remove from front and back
13:25:18 <Steven> ... remove = remove all space
13:25:29 <Steven> ... normalise = replace all to single spaces
13:26:13 <Steven> Erik: XML Schema has 'replace' that replaces non-space whitspace with space
13:26:46 <Steven> ... and collapse which replaces more spaces with a single (called normalise in XPath)
13:27:36 <Steven> Steven: SO the default would be preserve presumably
13:27:42 <Steven> s/SO/So/
13:28:44 <Steven> Alain: I prefer 'collapse' to 'normalise'
13:29:01 <Steven> Steven: Yes, 'normalise' is a bit technical
13:29:21 <Steven> Steven: What do we think?
13:30:01 <Steven> Erik: We thought about a type
13:30:09 <Steven> Steven: I like this because it is orthogonal
13:30:23 <Steven> Erik: Schema has a similar orthogonal facet of whitespace
13:30:48 <Steven> ACTION: Steven to write spec text for whitespace MIP
13:30:49 <trackbot> Created ACTION-2058 - Write spec text for whitespace mip [on Steven Pemberton - due 2016-03-23].
13:31:01 <Steven> Topic: New TR style
13:31:01 <Steven> https://lists.w3.org/Archives/Public/spec-prod/2016JanMar/0036.html
13:31:01 <Steven> https://w3c.github.io/tr-design/src/sample.html
13:32:07 <Steven> Steven: So I'm working on it; the requirements say you MUST have a piece of JS at the end of the document, that a wiki doesn't allow.
13:33:16 <Steven> Steven: It's still not particularly visible. I hope by next week it will be.
13:34:07 <Steven> Topic: Checking sections
13:34:22 <Steven> Steven: So I'm still waiting for comments/OKs on sections 7 and 8
13:34:27 <Steven> Erik: Not got there yet.
13:34:41 <Steven> Topic: AOB?
13:34:58 <Steven> Steven: Next week's call also an hour earlier
