Limitations of XForms Engine

Hi,

I just had a quick look at using the XForms engine [1] without the whole Orbeon forms system. Before I start extracting the XForms engine, I would like to ask for potential limitations:

1) Is the XForms engine itself capable of producing a pdf out of an XForm? As far as I have seen I can send an XForms document to the engine, is it possible to send a PDF template "on-the-fly" to the engine the same way?
2) Can the XForms engine execute all forms produced by the Orbeon XForms builder, or doesn't it handle orbeon-specific extensions?
3) Are there any other expected limitations beyond missing PFC and XML pipelines? I think the whole persistence layer doesn't make any sense anymore in this context, right?

Thank you very much!

It is not the XForms engine that produces PDF (this is not something
part of the XForms specification), but other processors that generate
PDF based on an XML document "created" with XForms (i.e. based on the
data entered by users in a form).

Form generated by Form Builder rely on XForms + Form Runner, which is
itself written in XSLT, XPL, XBL.

The persistence layer is part of Form Runner, and is used by your
forms when they run. You could isolate the core XForms engine, but it
would be close to useless without the rest. A little bit like the
Linux kernel would be useless without all the modules, glibc, the GNU
command line utilities, etc.

fr:autocomplete, delete, repeat, and dynamic itemset

Hello,

I'm working with a variation of Ethan Gruber's xforms to dynamically
autocomplete values for a repeatable field. The autocomplete values are
a dynamic itemset, retrieved by a web query to a solr index. Thanks to
Ethan's good work, the query and web response for the autocomplete
dynamic itemset is working quite well.

However, we have run into a problem where the xforms freezes when you
click on the trigger to delete one of the repeatable autocomplete fields.

I've run it on a number of different platforms and browsers, with the
same results. Looking at it in Firebug, I see this error is being
generated:

uncaught exception: ORBEON.xforms.Document.setValue: can't find
control id 'subject-field$external-value·2'

("subject field" is the id of the fr:autocomplete control. The
$external-value index number varies, depending on how many repeatable
fields you have.)

I'm running Orbeon dev-post-3.7.1.201004130300-CE. Attached is an
xforms you can use to test the behavior. The solr web service is
configured on localhost, but that isn't necessary to test the delete
behavior.

Any light you could shed on the problem would be much appreciated.

thanks,

-- Scott

Hi Scott,

Nice catch! And thank you for the simple reproducible example. I fixed
this one, and it will be in the next nightly build. You'll let me know
if it works for you. For reference, the bug is:

Form generated by Form Builder rely on XForms + Form Runner, which is
itself written in XSLT, XPL, XBL.

I would like to reformulate my question since I'm not sure if you got the question right: When I am designing a form with form builder, would the (extracted) XForms engine be able to produce converted XHTML from the XForms "source" (copied from the "Edit Source" dialog box)?

Thx!

Re: Re: Re: fr:autocomplete, delete, repeat, and dynamic itemset

Thanks, Alex!

It works great. I have a little CSS tweaking to do (the label is hidden behind the input), but it functions properly. This was a fairly debilitating bug in my form.

Bug with fr:autocomplete

Hello,
I change recently my Orbeon version and now, i have some troubles with
the line-codes with "fr:autocomplete"

I have the "Orbeon Forms dev-post-3.7.1.201004210047 CE" (what's the
difference with the PE version?) and Tomcat version 6.0.26. I use
Firefox version 3.5.9

An example:
When I write :
<xf:select1 ref="xxforms:instance('etablissementInstance')/rne"
appearance="minimal" >
<xf:label>RNE: </xf:label>
<xf:itemset
nodeset="xxforms:instance('listEtabInscritInstance')/etab">
<xf:label ref="rne" />
<xf:value ref="rne" />
</xf:itemset>
</xf:select1>

There is no problem, but when i write in the same place:

<fr:autocomplete ref="xxforms:instance('etablissementInstance')/rne"
dynamic-itemset="false">
<xf:label >RNE:</xf:label>
<xf:itemset nodeset="xxforms:instance('listEtabInscritInstance')/etab" >
<xf:label ref="rne" />
<xf:value ref="rne" />
</xf:itemset>
</fr:autocomplete>

I have an error page with "/[No error message provided.]"

I don't know where is the problem...

Any help?
Fabien.

In reply to this post by lacco

The "extracted XForms engine" doesn't exist, so I can't speculate on
what a piece of software that doesn't exist could possibly do ;). The
answer is yes, assuming that piece of code knows how to run everything
that Form Builder generates (tautology intended).

The bigger point is that this "extraction" has never been done by
anyone out there, because, IMHO, it doesn't solve a problem big enough
to be worth the effort. Or, said otherwise, because, so far, people
have found simpler ways to solve that problem (in some cases: separate
deployment).

Re: Re: Limitations of XForms Engine

Thx for your answer. While stepping through more Orbeon source code, I
got the same impression: There aren't only some classes which
undertake all the XForms work, it seems that some additional pipelines
& processors are needed for this, too. That's why I started another
thread where I tried to combine html-view.xpl and epilogue.xpl
pipelines to move in the correct direction:

http://orbeon-forms-ops-users.24843.n4.nabble.com/Which-Pipeline-for-XForms-XHTML-td2065893.html

Any help on this topic would be appreciated.

Re: Bug with fr:autocomplete (with test file)

In reply to this post by Fabien GUENEGO

Hello,

I write a test file for this problem. With the test file, we see that
the problem is not exactly the fr:autocomplete...
When i use the xf:select1, there is no problem.
When i use the fr:autocomplete, there is an error. And when i put "New"
in the session/nom node, I see the autocomplete field but, not the
choice item.

Any help?

Fabien,

There were some significant changes done to the autocomplete, so it is
hard to say what fails in your particular case. Could you attach to
your response a simple example that we can run the XForms sandbox
where you use the autocomplete control, so we can reproduce the
problem you're seeing?

Fabien,

Thank you for the example; you read my mind :). I am running it here,
and it seem to work fine. I click on the New button, the field shows,
I type 0 in it, and the two values (0671A and 0671Z) come up as
suggestions. This on Firefox. Are you seeing something different?

Thanks, Alex! I tested it against last night's build with my XForms
also, and it worked. It also looks like Winona's problem with the
select lists reappearing when you mouse click in another form element is
also fixed (I had that problem, too).

"Debouncing" autocomplete?

We've been using the fr:autocomplete component against a local name authority and are very happy with it. I'd like to tune those interactions a bit though by not making more service submissions than are necessary. I don't know what the precise algorithm should be. I imagine it would be something like "don't do a submission until either you have at least N characters or the user has stopped typing." I suspect the "stopped typing" part of that test would involve some trickier than average event handling. Has this already been done? If not, where in the architecture would it best be achieved?

I didn't find anything in the archives but I was using the perhaps old fashioned 'debouncing' to look for this topic.:)

Thanks,

Bill

Re: "Debouncing" autocomplete?

Hi Bill,

You can certainly write your code so you only make a request after
users have typed at least N characters. In fact, there is an example
of this on the section linked below. See how the variable
$make-suggestion is set and used.

http://wiki.orbeon.com/forms/doc/developer-guide/xbl-components#TOC-Dynamic-Itemset

As for not calling the service at every key stroke, this is already
happening. The autocomplete field uses in its implementation an
incremental input filed (xforms:input incremental="true"). Since you
wouldn't want an Ajax request at every request for incremental fields,
it implements an algorithm where it waits for a certain time before
sending key strokes to the server. By default this is set to half a
second, and you can change it by setting the
oxf.xforms.delay-before-incremental-request property in your
properties-local.xml. Alternatively, you could implement this behavior
in XForms. It sounds like a fun project to implement this in XForms
(well, to me at least!), but this is the type of things that can be
hard to get right, so setting
oxf.xforms.delay-before-incremental-request to a higher value is
probably a simpler solution.
