Re: Building a DOM Model with XMLForms
Scott, Your thoughts are quite logical. The initial implementation of XMLForm looked very similar to what you describe. If you go back in CVS to February-March this year, you will see that version. Over time I was convinced by Torsten and Konstantin, that form processing can involve a lot of business logic and access to multiple resources. This usually involves non-trivial code which is expected to be secure, high performing and readable. Implementing validation with a Transformer and then deciding on the next step with another transformer is applicable but for the most simple form handling scenarios. It can easily stretch the limits of a sitemap's responsibility, which is to organize content, not script business logic. I suggest that you think of a way to implement the wizard demo with the approach you suggest. If you can come up with a solution which will be acceptable to the group, then you can go ahead with the implementation. I'd be happy to apply the patch. Otherwise you should partner with Robert, who is already down the path of extending the currently implemented mechanism to support dynamic creation of DOM models. See his posts in the last few days.

The difference is that I'd like the XML docs written by the content people to define the resulting XML doc, without specifying it ahead of time. In other words, I'd like the elements attributes to be built by the XPath commands that originate from the XForm ref attributes. I'm using 2.1-dev, a fairly fresh snapshot. The design of the Form class in Cocoon at this point is that all the elements must be present ahead of time, or one get silent failures (Invalid data format could be a little more descriptive when the failure is because there is no matching path). Actually there is a matching path. Try the demo and type a random string in a numeric field. The Ivalid data message will appear right next to the bad field. My only point here is that the message is somewhat misleading. The response from the Form class is Invalid data format, while the actual error from JXPath is actually Cannot set property /somelement[0], the target object is null, which is really a different error, not format of data but the actual path itself. However, don't think that the JXPath Exceptions are fine-grained enough so that one can differentiate the two errors without doing some sort of string matching of the JXPath error message. This design makes sense when working with Beans as your Model, but could (should?) be more flexible with DOM; for example, if there is an either/or construct in your DTD ( !ELEMENT myelement (sub1 | sub2) ), and each sub element complex, you can't ahead of time know how to generate a DOM object that will have a given element available to XPath. Would it make sense within the scope of XMLForms in Cocoon to add the ability within the the Form class to add new elements to the DOM object when they are missing? It seems that this should be fairly simple: just define an AbstractFactory for the DOM, and use it within the Form class whenenver an access to an element fails for a DOM. Where the AbstractFactory would come from etc is a good question, though. I think that it makes sense to add the extra logic in the Form class. It should be relatively lightweight operation. As you suggestion in the Bugzilla entry, you can use the JXPath API for this. Right. I think the simplest approach would be a getJXContext() method. No big change. Maybe the same with other private vars? The reason I ask is that alternatively I could use something like Castor to rebuild a Bean for the expected XML document, biting the bullet that I can't hand over full control of the XML creation to the content creators. If people think that it's a good idea and doable to allow XMLForms to build a DOM based on the XForms elements, then I would strongly consider working on these modifications; otherwise I would probably take the path of least resistance go with a basic Bean approach. I think this is a good idea and I know that other people requested it before. It was actually a matter of resources until now. While working on this, please evaluate the DynaBeans in Struts 1.1 and see if we can borrow ideas from them. Well, I'm happy to spend a little time on this, especially if it might benefit others.

Kounis,
you have to insert the js snippet in a function and attach the function to whatever
event you want. baseurl is a variable containing the url pointing to the map:match
pattern=foo/bar in the cocoon sitemap.
The data flow is as follow:
1. a browser event triggers the js function
2. the js function send the xml data to the cocoon sitemap
3. the cocoon sitemap process the xml file through a source write transformer
4. the cocoon map returns to the browser a status message (and eventually other
generated xml)
5. the js function exits
Your mileage may vary, but the principle is this.

Re: Building a DOM Model with XMLForms
I believe that XMLForms are accessed by the pipeline via an Action Component, based on AbstractXMLFormAction. This is the Component that can would handle most of what you are saying below. The Action taken by the Action will depend on the command encoded in the request; one could, at the end of many pages, have a submit command that will tell the Action to validate, serialize, write to DB, email, etc. The only problem I've found is that the data Model, into which info entered into the form is written, must already be specified. This is particularly a problem with the DOM object, since it may not be possible to specify this ahead of time. As for DynaBeans (which are now part of the Commons not Struts, btw ), it seems that support for them will happen as soon as JXPath has support for them (which apparently is planned for v1.1). But I've just looked quickly at DynaBeans; I don't know how easily, with a JXPath that supports them, it would be to implement a dynamically built DynaBean with XMLForms. I guess that that would depend on how the createPathAndSetValue() routines work. rob On Sat, 12 Oct 2002, Scott Schram wrote: I've just begun looking at XMLForms, and I wonder if this makes any sense: When the client posts the XForm, we can start with a completely empty DOM which is filled in according to the XPath expressions in the XForm.

RE: i18n:when
From: Alex Romayev [mailto:[EMAIL PROTECTED]] Hello, Just wanted to follow through on the discussion from a couple of month back. There was a proposal that Konstantin was going to work on to implement i18:when tag as an alternative to using message files, so that you could have in the same file something like: Yes, that's true. And it was implemented by Matthieu Sozeau as we discussed. As the implementation was done long time ago (several months) it needs synchronization with the current version of Cocoon, but I hadn't time to do it. Though, if anybody needs the full implementation with updated samples and dictionary handling, just let me know (kpiroumian at apache dot org). page title i18:when locale='en'hello/i18n:when i18n:when locale='fr'bonjour/i18n:when /title /page But note, that this is not an alternative to message bundles, but an addition. You can still have all the pages generated from a bundle, but provide some specific messages for a particular language. Now here is my question (I'm making some assumptions here, so please correct me if I'm wrong): I18nTransformer is not cacheable, which generally is not a problem, since it is used as one of the last transformers in a pipeline, when most of the heavy-duty processing is already done. Now, this might not be true for i18n:when tag, which is most likely to be the first step in a pipeline and hence the rest of the pipleline is not going to get cached. Also note, that there is no reason why the result of i18n:when could not be cached. So seems that i18n transformer can be cached based on the selected locale and cache validity of the used dictionary. I have to think about it, but again I have absolutely no time to work on it, sorry. Is this concern valid or am I missing something? Seems reasonable and not only for the i18n:when case.

After investigating, I find adding -Dtarget.vm=1.4 solves that one, but why is this necessary?

Re: Building a DOM Model with XMLForms
Robert, Sorry for the delayed reply. - Original Message - From: Robert Ellis Parrott [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, October 11, 2002 10:35 AM Subject: Building a DOM Model with XMLForms Hi folks, I'm working on a project prototype where I'm trying to implement a kind of wizard using XMLForms. The difference is that I'd like the XML docs written by the content people to define the resulting XML doc, without specifying it ahead of time. In other words, I'd like the elements attributes to be built by the XPath commands that originate from the XForm ref attributes. I'm using 2.1-dev, a fairly fresh snapshot. The design of the Form class in Cocoon at this point is that all the elements must be present ahead of time, or one get silent failures (Invalid data format could be a little more descriptive when the failure is because there is no matching path). Actually there is a matching path. Try the demo and type a random string in a numeric field. The Ivalid data message will appear right next to the bad field. This design makes sense when working with Beans as your Model, but could (should?) be more flexible with DOM; for example, if there is an either/or construct in your DTD ( !ELEMENT myelement (sub1 | sub2) ), and each sub element complex, you can't ahead of time know how to generate a DOM object that will have a given element available to XPath. Would it make sense within the scope of XMLForms in Cocoon to add the ability within the the Form class to add new elements to the DOM object when they are missing? It seems that this should be fairly simple: just define an AbstractFactory for the DOM, and use it within the Form class whenenver an access to an element fails for a DOM. Where the AbstractFactory would come from etc is a good question, though. I think that it makes sense to add the extra logic in the Form class. It should be relatively lightweight operation. As you suggestion in the Bugzilla entry, you can use the JXPath API for this. The reason I ask is that alternatively I could use something like Castor to rebuild a Bean for the expected XML document, biting the bullet that I can't hand over full control of the XML creation to the content creators. If people think that it's a good idea and doable to allow XMLForms to build a DOM based on the XForms elements, then I would strongly consider working on these modifications; otherwise I would probably take the path of least resistance go with a basic Bean approach. I think this is a good idea and I know that other people requested it before. It was actually a matter of resources until now. While working on this, please evaluate the DynaBeans in Struts 1.1 and see if we can borrow ideas from them.

I think I could introduce another XSL stylesheet before this one which has use-request-paramters set to true and get the param that way, but it seems like it'd be slower to do 2 transforms with 2 separate stylesheets rather than 1 transform with 1 stylesheet.

Re: [Q] Pipeline best practices
Another issue of having too many pipelines. As i understand in the sitemap is generated into a java class. And the various matchers within a pipeline(s) are really a bunch of if-else if statements. So the more matchers you have (to match to a pipeline or various paths within a pipeline) your going to have a large series of if/else statements. And... since this uses string compares and wildcards and... if there's alot of these if else if statements it will lead to performance issues. It may help to break things up with sub site maps to help limit the searching. Or put the most likely pipelines to get hit first and the least likely last...

After reading Stefano's thread on dev (?) regarding the profiling work he did revealing that matching may be the most expensive operation, I've been thinking along these exact lines. The second one certainly seems to be the easiest to apply. Seems like search algorithm ideas apply here too - you want to get to a match in the least number of decisions possible, so either subsitemaps, or nested matchers seem the best ways to implement a good decision tree. Seems like laying out url space can help this. Question: wouldn't in theory subsitemaps carry more overhead than nested matchers? Of course there are many reasons to use them any way but this would be a factor in deciding when. I don't see any benefit (besides different configurations as mentioned) of multiple pipeline sections, unless each one has a small number of top level matchers that can help eliminate all options quickly.

Anyone know? --- Katzigas Dimitris [EMAIL PROTECTED] wrote: I think that your code is OK. xsp:logic String productId = xsp-request:get-parameter name=productid/; /xsp:logic This code is right above my root document element But i think that you have to put the whole xsp:logic fragment inside your root element. I think that in order to use the xsp-request:xx tag it has to be inside your root element. I Hope that will help.
