recursive XBL components?

I'm getting a out of memory error whenever I have one of my xbl components self reference or recurse. Is that not allowed? Or is there some trick to getting it to work?

I have some xml that look like:

<widget-item/>

<widget-item/>

<widget-item/>

</widget>

I have an xbl component that for the widget, and one for the widget-item

the widget xbl look kind of like this:

<xforms:repeat nodeset="*">

<xforms:group ref=".[name() = 'widget']">

<dlcn:widget ref="."/>

</xforms:group>

<xforms:group ref=".[name() = 'widget-item']">

<dlcn:widget-item ref="."/>

</xforms:group>

</xforms:repeat>

Jeremiah,

I understand that in the implementation of dlcn:widget you have an
xforms:repeat that iterates over <widget> and uses dlcn:widget. If
this is the case, and you get an error, it is most likely because this
has never been tried ;). Could you submit a simple component and test
case that shows this, so we can easily reproduce it?

Re: Re: recursive XBL components?

What format would you like it in? I'm not sure what pieces you'd like since it's XBL.

Re: Re: recursive XBL components?

In reply to this post by Alessandro Vernet

Just out of curiosity, is there some other common way to walk an xml tree of unknown depth? I would have used some xsl for the recursion, but I can't seem to get my hands around the instance data with the xsl within the xbl component. It seems like only xforms can grab the instance data, while xsl is limited to the xforms elements themselves. It'd be great if there was some way to apply an xsl template to an instance.

Give this component a single node binding and it will create xhtml:li for all of it's attributes,

Jeremiah,

Do you also have a test case for this? I.e. XForms that uses this XBL
and shows the problem?

Re: Re: Re: Re: recursive XBL components? TEST CASE/REAL EXAMPLE

I sure don't I wasn't quite sure how to package all of that up, so I wrote this to take any single node binding. My orbeon environment is a little different from the standard and has lot of other infrastructure built around it that makes it difficult to pull out a single xhtml file. If you'll point me to an example of something I'll pack it up for you.

Jeremiah,

The easiest thing is to create a stand-alone XForms file that we can
run in the XForms sandbox. You can embed the XBL in the XForms file,
so there is just one file.

Re: Re: Re: recursive XBL components?

In reply to this post by Jeremiah Jahn-4

Jeremiah,

Regarding the format, a single XForms file that contains the XBL is the best.

And regarding dealing with instances having an arbitrary level of
nesting, in general we use xforms:repeat to produce a UI that shows
the nesting but where the generated markup is itself is not nested, as
XForms doesn't allow you to do it, and we don't support it (yet!) the
way you did it with XBL. See:

http://wiki.orbeon.com/forms/how-to/edit-hierarchy

I would have used some xsl for the recursion, but I can't seem to get my hands around the instance data with the xsl within the xbl component. It seems like only xforms can grab the instance data, while xsl is limited to the xforms elements themselves. It'd be great if there was some way to apply an xsl template to an instance.

Jeremiah,

I am not sure if you intended to post a follow-up on this thread or
not, but the last message you send arrived empty (with just a quote of

it should have had an attachment. I've sent it again. I've run this in the sandbox, and the result was the same heap space error.

Jeremiah,

I was able to reproduce it with your example, and I created a bug to
track this (link below). Using XBL this way is a smart idea, but we're
most likely not going to implement the support for recursive XBL
component in the short term, unless this gets sponsored by a client.

Re: Re: recursive XBL components? TEST CASE/REAL EXAMPLE

I understand. Would you mind giving me a pointer to place in the code where this is most likely occurring. Not saying I've got the time to do anything about it, but I'm curious to see whats going on.

Re: Re: Re: recursive XBL components? TEST CASE/REAL EXAMPLE

Jermiah,

The issue (or the feature ;) is that XBL templates are applied
statically, before XForms processing proper even starts.

Processing starts with the initial XHTML+XForms document:

* any element with XBL binding (say <foo:bar>) is then processed
** a shadow document is created from xbl:template (applying
xxbl:transform, xbl:content, xbl:attr, etc.)
** processing of the resulting shadow document starts recursively

So if your XBL template for <foo:bar> keeps recursively producing
<foo:bar> elements, recursion never ends.

To stop recursion, possibilities include:

* having a condition in the template to stop recursion
** this means stop producing <foo:bar>
** this will work only if the recursive structure can be statically
determined before XForms processing starts
* support dynamic alterations to the XHTML+XForms DOM, i.e. you could
dynamically insert <foo:bar> elements during XForms processing
** this is harder to implement

Not sure how much that helps!

-Erik

My orbeon environment is a little different from the standard and has lot of other infrastructure built around it that makes it difficult to pull out a single xhtml file. If you'll point me to an example of something I'll pack it up for you.
