Continuations loosing state
It seems that when I use continuations that it is losing a lot of state. My method and environment sets up a lot of information, but all of it is lost every time I resume the continuation. Yet with CForms it seems to save state properly. What gives? Is there some manual method of saving and restoring state that I have to do? In short they are not acting like proper continuations and instead are only maintaining the program stack w/o state. -- Berin Loritsch Owner Work: 571-215-7708 Email: [EMAIL PROTECTED] IM: [EMAIL PROTECTED] (MSN) http://www.linkedin.com/in/bloritsch D-Haven 20044 Great Falls Forest Dr. Great Falls, VA 22066 USA See who we know in common Want a signature like this?
Need a new Forms Sample (and other improvements to forms)
Based on my experiences with CForms, I have to say that I am very
frustrated. Yet at this point we are committed. I think something
that would greatly reduce my frustrations as well as other potential
users is a full soup to nuts explanation of how to set up forms for
your existing application from scratch. Next, and possibly just as
important, how to use CForms to do tag management like del.ico.us and
Flickr. There should be three tracks depending on what you bind your
form to. I'm not the guy to do it because I am completely lost and I
can't seem to make heads or tails of where I am in the process or what
is going wrong.
Now, as to improvements to forms, there are some things that are
absolutely necessary in order to make use of CForms. First, is a
special type of sitemap. An extension, if you will, that automatically
adds the matchers necessary to resolve the _javascript_ resources instead
of relying on people to set that up themselves. It would also include
the declarations for the CForm specific
generators/selectors/serializers/transformers/etc.
Additionally, there are two ways to set up forms depending on whether
AJAX is enabled or not. Typically you have a generator followed by a
transformer. Why not make one forms generator that handles that for
you (i.e. auto-chains the necessary transformations right after the
source is generated ala JX script)? Also there is a transformation
followed by a choice of serializer. Again, why not have a forms
serializer that takes care of the final transformation and choice of
serializer for you?
It took me a week of trial and error to figure out why things were only
partially working on an upload form. I finally have it working, but
the AJAX enabled portion is not doing its job right. There is more
trial and error and I don't have another week to futz with it.
At this point, I'm going to have to give up on doing things the CForms
way and hack together something that is far less elegant but I know
will work. At least I will be able to report progress. I'm sharing
these observations in the hopes that we can avoid having more folks as
frustrated as me.

Re: Bean Binding and Repeaters...
Thank you very much for the help so far. The boolean is rendering
properly, and it looks like I need to create a custom binder. So, how
do I add that custom binding to the CForm? I saw the interface, I just
need to hook it in.
Simone Gianni wrote:
Hi Berin,
First, in both repeaters you should specify that id is the identity
field. Without the identity field the repeater binding is not able to
find match a row with a bean in the list.
When the repeater receives all the request parameters, it takes the
terms.0.id (or any other identity field you specified, you can specify
more than one) and searches in the list for a bean having that termId.
If it finds it then execute the rest of the binding against it,
otherwise the row is marked as being a new row and a binding to create
the new row is searched. Since there isn't any, something is written in
the log file and that repeater row is discarded. But the most harmful
thing is that after doing all this, it searches for all the beans that
didn't matched any row in the repeater, and removes them from the list,
even if there is no explicity binding to remove them. While JXPath is
not able to add a new bean in a collection without an explicit binding
(since could not know which class instantiate), it's extremely able in
removing them :)
Second, we usually put the of a repeater inside an
. Somewhere between 2.1.6 and 2.1.7 AFAIK fb:on-bind was
introduced and many repeaters didn't worked correctly if it's not there.
Third, the *** is correct?
you have a getIsPostHT() in your class? I think this is a common
mistake, and believe it should be ** since you have either a public boolean isPostHT() or
public boolean getPostHT() in it.
So, it should be :
Let us know if this works any better.

Bean Binding and Repeaters...
I haven't seen this anywhere, and I need to know how to do it. I've got a bean that has two lists with the same type of object in each list. For example: CountryHotTopics --- tags hotTopics Both lists (tags and hotTopics) are filled with Tag objects. I'm trying to have CForms manage the relationship. In essence, a "Hot Topic" is a tag that is marked as being important so a link to a list of items marked with the tag is displayed on the front page. The Tag object has four attributes: Tag - id name isHotTopic longName (the last one is for how the hot topic is displayed). I've got the CForm displaying the information in the database--even though the doesn't display checked if Tag.isHotTopic is true. I need the CForm to add a reference to the Tag object to the CountryHotTopics.hotTopics list when it is checked. But before I can get there, I'm still struggling with basic binding. When I click the submit button for the form, I get an exception in the part where CForms is supposed to save back to the object: Factory [EMAIL PROTECTED] could not create an object for path: /terms How do I control/specify the same type to convert the form results to?

Pointer to good Java Binding Cocoon Forms docs?
I am at a point where I need good step by step instructions on binding
a CForm to a Java object (in the JavaBean idiom). I'm talking from the
beginning. The reference docs on the Cocoon site are "ok" if you have
the environment set up already. I have done Google searches and tried
following the samples, but I'm still hit and miss here.
I'm staring up the end of a deadline and I only have some frustration
to show for it. I believe I only need some coaching at this point, but
there isn't anything that really qualifies for "This is where you begin
and how things work together". I need some kind of pointer, please. I
know CForms works, because of some of your comments. I just can't seem
to get it working for me.

CForms and Uploads?!?!
I am beyond frustrated with trying to adapt the CForms upload feature to our application. I have about two hours left for today, and I'd like to get it working, but if I can't I will resort to the traditional method of forms and actions. Please, if you have bandwidth to spare, contact me on MS Messenger: [EMAIL PROTECTED] I'm experiencing strange things. Once the initial form is displayed and sent to the server, whether everything is OK or not, it goes to the "success" scenario. Worse, the "success" scenario is a cocoon stack trace with a SAXException saying "No Cocoon Form found." Nothing I can see in my sitemap or flowscript suggests that that should happen, and yet here I am. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

There are indeed some differences between calling JXTemplate from flow
or directly, though I don't recall what these were exactly (would need
to check the sources). Some things you might try until someone more
experienced helps you:
* instead of "cocoon.parameters", use just "parameters"
* try JXPath instead of Jexl: #{$cocoon/parameters/something}
* or if you're on Cocoon 2_1_x head, use the template block instead
(just switch the jx declaration to o.a.c.template.JXTemplateGenerator)
which should solve these differences
It turns out that you can't use Java Objects other than string if you
are passing from the sitemap. I consider this to be a bug.
Particularly since you can't pass in anything through
cocoon.request.getAttribute() unless you go through a flowscript?!? I
eventually had to bounce the request through a flowscript just to get
the value passed. It's a pain in the arse.

Large Navigation Menus?
Does CForms have easy ways of using forms to navigate a complex structure? We have a set of over 400 locations in a hierarchy, and over 200 topics in a hierarchy that we need to let the user navigate. The current solution we have (using a third party Javascript library) introduces over 5 seconds of client side rendering with this scenario. That's unacceptable for our users, as some of them have already waited over 8 seconds for the page to download. A solution that would allow us to navigate one part of the hierarchy at a time would be ideal. All our clients are using IE 6, with a very small minority using IE 5.5.

I cannot change this API and it really has to be used exclusively. Why don't you make your NonThreadSafeComponent thread safe? In the easiest case just add "synchronized" to each method. To assure that it is a singleton you have to implement ThreadSafe then. Oooh, that's dangerous advice. There are two incredibly huge reasons why you shouldn't just blindly add "synchronized" to each method: 1. You pay an enormous price in synchronization overhead. As all the threads contend for the monitor, you are limiting only one client to have access to the component at a time. Sometimes it pays to have an instance per thread, or an instance per request to avoid monitor contention. 2. Blindly adding synchronized does not protect you from race conditions. Take for instance a Queue situation. One thread waits until the Queue says it has an item available polling the "size()" method--access is synchronized by the way. Another thread steals the instance before the first thread has a chance to pop the item off. The first thread's code dies because it assumed there would be something available. I realize the last example was contrived, but it was to show that if you are relying on methods being called in a certain order you can't rely on that order in a multithreaded environment--even if the individual methods are synchronized. The way around that is to use a token for the thread's "session" with the component. That token would hold whatever state is necessary for a particular thread's conversation with the component. Point is, you have to plan for concurrent access, you can't just add the synchronized keyword to a method signature. You realize that by doing that the synchronization object is the whole object that the method belongs to? Typically there are only a couple objects that really need synchronization around them within the parent object, so you can minimize thread contention by only synchronizing on the parts that really need to be synchronized. That minimizes the time spent in monitor contention mode. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The problem is, that i need to have exclusive access on object

Using the Threadsafe interface will cause the need of java
synchronization:
synchronized (myComponent) {
myComponent.doSomething1();
myComponent.doSomething2();
}
This is in any case a bottleneck, but i intended to delegate this to
the component manager.
My component is not thread safe and it is not possible to make it
thread safe.
Ok, I'm a little confused now. I thought you asked how to make
something a singleton--which is what I shared. Now you are saying that
is not really what you need.
Without having any more details, I'm not sure how I can help you out
further. If you can help me understand a bit better what it is you
need, I can help you find a solution. Is it possible to use the actual
code itself or is that an NDA or corporate secret? If not, can you get
as similar as you possibly can without violating your employer's trust?
I suspect that you may need another component to do aggregate work, or
something of that nature. I'm not sure. When everything is called
"component" its hard to understand what you are really trying to accomplish.

Re: SQLTransformer makes Cocoon hang under high load
Fabrizio Sitzia wrote: Hello, I'm developing a dynamic Cocoon webapp that performs a lot of (nested) queries using the SQLTransformer. The SQLTransformer performs SELECT operations only, and it is configured to use a JDBC database connection pool that is managed by Cocoon itself. Excerpt from cocoon.xconf: ... At some point, I decided to stress-test the webapp using the 'ab'-tool (Apache benchmark) to simulate a large number of concurrent requests. When the number of concurrent requests is heading towards the 'max' number of pooled database connections, the following occurs: - The 'ab' benchmark is aborted with a timeout error. - Using a database monitoring tool, you will notice that the 'max' number of pooled database connections have been left open. - Cocoon 'hangs' indefinitely! Any further requests to the webapp will timeout, and nothing gets written to the logs (access.log, error.log...) There are no warnings, nor any error messages in the logs that would indicate why the hang occured in the first place. Up to the hang, everything appears to run normally! That's scary! It sounds like SQLTransformer naively gets a new connection per query. This in turn requires that if your page has 4 nested queries then SQLTransformer is using 4 of your 50 connections. It only takes 13 simultaneous requests to use up all the connections at that rate, and if all your requests have anywhere between 1 and 3 connections reserved and are not finished yet, none of the pages will release the connection and a deadlock occurs. If you have as many as 10 nested queries it is obvious to see how something like this could occur. I think the ESQL logicsheet suffered from this many moons ago, but resolved it by requesting one connection per page. BTW, Microsoft's feeble driver is limited to one connection per query--so your choice is to use jTDS or some other company's version. Nonetheless, it seems like there is a bug in SQLTransformer.
