Re: Role based security
Sam, I finally read the full text of your message. :-) There is huge overlap between your requirements and mine. My application also had the issue that role-based security was not sufficient. I used a custom imlementation of the Acegi AclProvider to control (on a per-entity basis) how much could be seen or if links were generated to access certain records. This could be used in addition to, or in place of, the role-based access. I didn't need to filter result sets as was your case. I would be very interested in seeing what you have put together. Apart from the authorization issues, I have yet to see a nice performant Hibernate table model. This thread has prompted me to start cleaning up my code and packaging it into a library. With the carmenconsulting page-level security option on one end, role and instance-based acl security with my work, and your work including hibernate-level collection filters there could be a great set of options for securing tapestry apps.

That's what we have for handling role based auth in a template, including some sophisticated else handling which lets the template cascade through a number of options.

Our @IfAuth component just checks whether the current user has a particular permission (read, write, and deny basically). We've actually got permissions assigned on a per-property basis on many objects, so we also have wrapper components which wrap the normal form components with the IfAuth conditional so that our templates aren't full of difficult-to-read conditional blocks. The entire chain of possible permissions are represented in a single component, so if they have write permission, they will see a text box, read permission will show a label, deny will show a blank space, etc. We actually went a step further and built a single component which renders any number of form components based on the type of the value being assigned. Booleans get checkboxes, lists get palettes, strings get text fields, numbers get text fields + number translator, etc. Each also takes care of rendering correctly according to the permission available to the current user for the field in question. It is similar to bean form, but pre-dates it by quite a bit. We do have an IfRole component for the few places where we have to check whether a user is a particular role, such as when deciding whether to render a particular menu item. All of this could plug into Acegi or any kind of authorization mechanism you might care to roll into your app. So long as you can define some kind of AuthorizationDelegate that you can provide to the tags for doing the auth and returning a permission, it is pretty easy to implement and/or modify the auth mechanism. We also have record based security which is implemented entirely via hibernate filters and AOP interception which ensures that none of the service methods can be executed without having the appropriate hibernate filters enabled. This was necessary in order to handle things like tables with paging. The acegi mechanisms don't appear to provide a way to ensure that db queries only return the rows for which the current user is authorized, so offset/limit queries don't work correctly when acegi removes items after the query has run. This breaks the paging in the tables. So we use hibernate filters to ensure that any query that runs only ever returns the results appropriate for the current user. I'm intending to write a paper about this mechanism that folks can see, as it turned out to be incredibly flexible and very efficient. It's got unix filesystem style permissions (owner, group, world - although it is actually a little more sophisticated than that) and multiple permissions that can be applied to each (read, write, reassign). It also provides hierarchical auth, so you have the same permissions (or better) as any user below you in the hierarchy - allowing managers to have the same access as their direct reports, without explicitly assigning them to each record owned by a direct report. This is vital if any user might ever be moved within the organization. It also allows temporary owner reassignment without removing the original owner assignment. This allows employees to be assigned to cover for others during vacations and such without forcing the system to explicitly remember who used to be assigned where and then reassigning at the end of the period. The whole thing is completely transparent outside of the service layer. The DAO layer knows absolutely nothing about the authorization filters and neither does the ui layer (except, of course, where we've exposed fields you can edit to modify assignments and such).

RE: Role based security
Borut, Sorry. I don't have this in a library yet - the applications I've been working on lately have rather flat security requirements so I haven't extracted this out into a library. Here's a little snippet out of the menu section of my Border component for sample usage: Month Calendar Agent Console New Estimate I could have cleaned this up by getting rid of a few tags and specifying the "element" property for the @Authorize component. (Remember, it really does behave like an "If" - you can even use the Else with it.) The hard part I found was the Spring side of my plumbing - I jumped into the deep end implementing org.acegisecurity.userdetails.UserDetailsService. I also have a rather hacked-up way of doing my authentication borrowing from EWDT. If you can start out getting things working as described in the Wiki, and then incorporate my stuff that's what I would suggest. Basically, once you have a SecurityContextHolder containing your SecurityContext, things get much easier.

Re: T5 IoC - inject service in data class ?
Pardon my inexperience, but I'm having a little difficulty getting my head
wrapped around all of these IOC concepts. I've read through much of the
documentation on the tapestry website, but I'm still having a hard time
understanding it all.
So I should create a data factory service to handle the creation of my data
objects, and presumably include a buildDataFactory method in my AppModule
with an @InjectService("ListService") as one of the parameters. How do I go
from there to having it as something I can use in my data class? Would I
pass the service into the data class have it store a copy there (doesn't
sound like a good idea) or should I restructure my data class to not need
the service (it's possible in this case)?
Also, what is the benefit to having more modules than AppModule?
And re: updating the MANIFEST.MF, is this in regards to the external jar
where my ListService is in?
Thanks and sorry for the abundance of questions!

The pattern of use is:
You create a factory service for your data object. The data object's
dependencies are injected into the factory.
You ask the factory for the object, it instantiates the data object
with the dependencies.
buildDefaultRegistry() builds a new registry, not what you want.
Be aware that the dependencies will be runtime-generated proxy objects
that are not serializable.
You can have additional modules, not just AppModule ... there's doc in
the tapestry-ioc section to discuss how to update MANIFEST.MF with the
necessary data.

Re: Untetermined count of form elements
Why wouldn't work (where textproperty is an edittable property of each option object from optionList? When the form submits, the Loop will bet involved and will iterate the elements in the list again, keeping the option property upto date before each textfield pulls a value from the request.

hi all,
when i try to send data via "tapestry.bind" to my Tapestry page from
a page with a dojo editor (editor2) i get following javascript exception:

i set up a maven project where i can reproduce this anytime but i
dont know what is causing this exception. When i view the raw html
template in FF (... the not generated html ) everything works fine.
i hope someone can give me a hint. is it related to the keyhandlers of
the editor? why does it matter if do a ajax call?
please help
my code looks like this:
editor.js
var editor = null;
function startEdit(e) {
editor = dojo.widget.createWidget("Editor2", {

var k = dojo.event.browser.keys;
// listen to key events
editor.addKeyHandler(k.KEY_ESCAPE,null,listenESC);
editor.addKeyHandler(k.KEY_ENTER ,null,listenENTER);
}
function initEditor() {
dojo.event.connect(dojo.byId("edit"), "ondblclick", "startEdit");
}
function listenESC() {}
function listenENTER() {
...
asyncListenerDoSave(data);
...
}
asyncCaller component:
dojo.require("dojo.dom");
dojo.require("dojo.dnd.*");
