You'll find some Struts-related on the Cocoon wiki [1].
First, it has to be said that Struts and Cocoon can cooperate smoothly,
Cocoon playing in that case the role of a JSP, but providing way more
capabilities such as multi-channel/format responses.
Now Cocoon provides features that make looks Struts like a very
primitive and less-productive thing:
- flowscript, to write controllers without the traditional hassle of
handling state automata
- Cocoon forms, to build sophisticated forms in a declarative way (no
need for a form bean)
And of course, combining flowscript and CForms is a _very_ productive
combination.

It's not a similar mechanism, as it's just an adaptation of Cocoon's
flowscript to Struts ;-)

[CForms]When using fi:groups with style tabs calender select is behide the layer
Hi,All: When using fi:group with styling tabs like: fi:group fi:styling type=tabs / If there has widget which its type is datetime,the calendar select box is under the tab div.So you can't select date from the calendar select. My environment: cocoon 2.1.5.1 IE 6 I think it is a bug,can anyone fix it ? Roy Huang.
RE: [CForms]When using fi:groups with style tabs calender select is behide the layer
Set the CSS property z-index to a value greater than the frame, and it will apear.

Re: [CForms]When using fi:groups with style tabs calender select is behide the layer
This problem has come up before, there may be even a bug reported about it in Bugzilla. IIRC someone came up with a fix and was going to contact the original author of the calendar widget to see if the fix could be applied there. In any case I would check bugzilla and add the bug + patch if it's not there already. A wiki entry explaining the problem and how to fix it might also be helpful.

always has to appear on top of anything else.
Do you know what the maximum value for z-index is?

I guess it has no maximum value. At least I can't find it here:
http://www.w3.org/TR/CSS21/visuren.html#propdef-z-index
Integer is defined is as 1 or more '0..9', also here is no maximum
specified (it does say that some elements may specify a max).
Maybe the maximum of a 16bit or 32bit int would be good?

Cocoon and security (JAAS or J2EE??)
Hi all, I've been looking for a good method of securing Cocoon web applications. I think that authentication/authorization via JAAS or via the web container are good methods. Are there any implementations available that integrate Cocoon and these security mechanisms? And if so, what are the possibilities of declarative security and authorisation in sitemaps? E.g. declaring that a pipeline can only be executed by users with a specific role? Thanks, Bart.
Debugging Cocoon Applications
Does anyone have knowledge of a plugin for Eclipse (or other development environments) that would allow me to set break points in a sitemap and step through a pipeline - inspect parameters, session etc. Normally at present I bring Cocoon into Eclipse and set break points or use RHINO Flowscript debugger as required. Failing all of this what are the key place to break point in code - ie at start of pipeline, genberator, transformer etc really appreciated JENNY _ Want to block unwanted pop-ups?

The code is available from http://wiki.apache.org/cocoon/FlowAndWebServices if you're interested in taking a look. The impetus for getting this going came from an application I was working on where I needed to direct the flow of control based upon the response from a remote service, something not easily done using the SOAP logicsheet or WebServiceProxyGenerator. The code probably needs a bit of a tidy up, I'm not hugely familiar with the Avalon component lifecycle. I also lifted the CompilingClassLoader code directly from the FOM javascript interpreter - I'm sure it could be better optimized for this purpose. Cheers Adam Adam, Wow, this looks really promising! Pls, could you file a Bugzilla report and add the ZIP file there. Many thanks! Best, Reinhard
Changes in Rhino-cont implementation
Sylvain Wallez wrote: Igor Bukanov wrote: It is hard to implement catch(continue|break|return) correctly. For example, what should happen if an exception is thrown during the execution of code there or what if continuation is captured/restored inside the catch block? Depending on the situation the version in Cocoon would either throw an exception or go into infinite loop. AFAICS respecting finally has rather simple answers in all those corner cases and that is why I put efforts to implement it rather the catch blocks. For compatibility a special mode can be added in principle to Rhino from mozilla.org with support for arguments.continuation and catch(...) with the clear marks about deprecation (unless, of cause, it is possible to implement the constructions simply and efficiently - then no deprecation!). But my continuation curiosity does not spread far enough to create such patch. arguments.continuation, AFAIK was never documented publicly, so we can safely forget about it. For the special catch syntaxes, there will be some compatibility problems as many people are likely to have used it. But since the use of finally seems to allow the same kind of behaviour with a simpler syntax and a clearly specified semantics, I think it is our job, we cocooners, to prepare our user base to this change and give them directions to upgrade their scripts. I think we should deprecate this syntax in the next Cocoon 2.1.x release and in Cocoon 2.2 we can use the new Rhino continuations implementation - this also gives us more time for testing. -- Reinhard

I'm currently using that block, and wrote a pipeline that simply puts the request.getUserPrincipal().getName() (or whatever the API call is exactly) to authenticate a user (well, the user is already authenticated but it lets the authentication framework know that the user is authenticated). That works fine. I also know that I can protect documents with that framework, but how can I specify that only users with a specific role can view that document (pipeline)?

The booleanfield (checkbox) fi:styling submit-on-change=true/ fails to submit the page when the checkbox value is changed (checked/unchecked) and yeilds an error when the page is submitted with the field unchecked.
