RE: [deng-talk] Deng and xforms questions

Wonderfull thanks, that clears most things up. I do like DENG because it is quite lightweight, my webapp with axis web services, eXist xmldb, and a few other 3rd party components was already getting a little heavyweight so I sort of like how DENG was with just a few pages. I managed to generate the xforms dynamically and let DENG at it. I could probably work around most of the things you mentioned, but the one I think I would need is that setValue on a 2nd instance. That way I could have the full xml instance be first and then a second instance of what the user was editing. The setValue you have I think would work, but requires a "click" hence a button which I really don't want. Okay I guess I will wait around till the next DENG, until then I will look into other things like the heavier chiba or orbeon. Doubt I could help much; probably like everybody else I am quite busy. And to be honest I don't know FLASH at all, but I guess if you wanted any kind of XML/XPATH/XQuery type help then maybe I can look at a few things. If you told me where to actually look for all the source code, so far I have not looked at any files with DENG.

The XForms way of doing this is via the "lazy authoring" [1] (instance creation out of form controls [2]), which is not supported by Deng..

I againt tried several things to use setvalue and > nothing. your setvalue should work but it is not for a couple of reasons: 1) xforms-ready is an event targetted at the model, not at the form controls 2) xforms-ready is not supported by Deng anyway :-) while Deng has full XML-Events support, the only event actually defined is "click", which is the wrong name for what should now be called "DOMActivate" so that setvalue should work if you use a trigger: <xf:trigger> <xf:label>click me</xf:label> <xf:setvalue ev:event="click" ref="......">....</xf:setvalue> </xf:trigger> > **side note: I have just noticed that the xforms namespace I use does not > have the "/cr" at the end, but I suspect that does not matter. The controls > seem to be rendered correctly and data is being submitted. yes, both namespaces are supported in Deng. I am sorry to see Deng seems to be falling short of your requirements, Deng development is currently split between a full rewrite [3] and a port to non-flash javascript environments (like IE or Mozilla) [4]. While the first effort AFAIK has not released any code yet, the second offers some improvements over the old Deng: the DOMActivate event, partial "relevant" model item property support, select controls, repeat controls with number > 1.... Any help/patch/code/suggestion will be highly appreciated on both fronts, thanks ciao ste [3] http://wahlers.com.br/claus/blog/?p=21 [4] http://demaledetti.net/ugo/ > ---- > <?xml version="1.0" encoding="iso-8859-1" ?> > <html xmlns:ev="http://www.w3.org/2001/xml-events" > xmlns:xsd="http://www.w3.org/2001/XMLSchema" > xmlns:xf="http://www.w3.org/2002/xforms" > xmlns:xforms="http://www.w3.org/2002/xforms" > xmlns:xs="http://www.w3.org/2001/XMLSchema" > xmlns="http://www.w3.org/1999/xhtml" > xmlns:xhtml="http://www.w3.org/1999/xhtml" > xmlns:vr="http://www.ivoa.net/xml/VOResource/v0.10"> > .... > > <xforms:model id="model1" xmlns:xforms="http://www.w3.org/2002/xforms"> > <xforms:instance id="resinstance"> > <vr:Resource > xmlns="http://www.ivoa.net/xml/VOResource/v0.10" > xmlns:vr="http://www.ivoa.net/xml/VOResource/v0.10" > xmlns:vs="http://www.ivoa.net/xml/VODataService/v0.5" > xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > xmlns:xs="http://www.w3.org/2001/XMLSchema" > updated="2004-11-20T15:34:22Z" status="inactive"> > <title>File Manager Service Entry</title> > <shortname/> > <identifier>ivo://@REGAUTHORITY@/filemanager-one</identifier> > <curation> > <publisher>testcont</publisher> > </curation> > </vr:Resource> > </xforms:instance> > > <xforms:submission method="post" > action="http://localhost:8080/reg/xforms/XFormsEditEntry.jsp" id="s00"/> > > <!-- the instance data text tends to show up in the text box, but the > required does not work > decided to add constraint to see if it makes a difference nothing.
