How do you feel about requiring JRE 1.6 for Tapestry 5.4?
When in doubt, let's ask the community: would you object to requiring JRE 1.6 for running Tapestry 5.4? So far, T5 has run on JRE 1.5 but the time for requiring 1.6 will come at some point. Not necessarily yet - we can likely work around this - but current Hibernate 4.x releases are built with 1.6.

Java 1.5 was EOL in 2009 by the looks of it. There are no security updates for this release. Supporting an EOL product with no security fixes can only affect the integrity of Tapestry and the containers that it is run in. Java 1.6 is EOL November this year (2012) http://www.oracle.com/technetwork/java/eol-135779.html On 02/05/2012, at 5:48 PM, Peter Stavrinides wrote: + 1 - Original Message - From: Dimitris Zenios dimitris.zen...@gmail.com To: Tapestry users users@tapestry.apache.org Sent: Wednesday, 2 May, 2012 10:32:14 AM Subject: Re: How do you feel about requiring JRE 1.6 for Tapestry 5.4? +1 from me also On Wed, May 2, 2012 at 10:25 AM, Markus Grell tapes...@military.de wrote: With Java 6 released end of 2006, I can't see any point in supporting an older release for a new Tapestry version.

Sidepanel with pagespecific items
Hi, In my current project I want to add some kind of side bar with some extra functions/data in the form of icons with a panel that slides open (javascript). These items can be global or more page specific. Example: Search: visible on every page Notes: visible on specific pages, containing data based on a Person object Errors: only visible on dashboard page, based on Policy object The visual styling html/css/jquery are no problem, but I don't know how to implement this with Tapestry. Does anyone have some guidelines on how to start this? I made a component SideBar and added it to my Layout component. Then I thought of adding Block items to this component, but I'm not sure how to add these from within a page. So in short: no idea how to start on this; any hints are appreciated.

I favor switching to 1.6 when there is a significant benefit to doing so, and not before. I wouldn't want to give anybody a reason not to use this great framework.

Re: Sidepanel with pagespecific items
Hi,
Thanks that's what I needed. I have now the global items in my Layout
component. And I can add some from within a Page as a parameter.
My code at the moment (simplified):
*Layout.tml:*
div id=sidePanel
[items that are shown on every page]
t:delegate to=sidePanelContent /
/div
*Layout.java:*
@Parameter
private Block sidePanel;
public Object getSidePanelContent() {
return sidePanel;
}
*Dashboard.tml:*
p:sidePanel
${policy.holder.name}
/p:sidePanel
*Dashboard.java*
@Property
private Policy policy;
Object onActivate(Policy policy) {
this.policy = policy;
}
This works...
Now what if I have another page, lets say Simulation. And I want to add
that same content as a parameter like in Dashboard. How can I reuse this
code instead of adding this in every page I want to show this in.
I've tried making an extra component between the Layout and the Page where I
put the common content to be added in a parameter. But then I had a problem
accessing needed properties from my pages (policy in my example)
Then I thought I could use inheritance and put the onActivate method in the
parent class. But I think that's not gonna solve my problem...
Maybe I should just create a component for each type of content I want to
add to the sidePanel and in every page add the wanted components..?
Hope you understand what I meant in my above rant and can give your thoughts
on this.
Thanks

Re: How do you feel about requiring JRE 1.6 for Tapestry 5.4?
If the only reason we're moving to 1.6 is to support a newer version of hibernate in tapestry-hibernate, then I'm -1. I specifically know of a corporation out there using tapestry that still uses java 1.5. Where there's one, there are many. I suppose we could write them off as stuck on tapestry 5.3.x, but unless there's some major benefit to switching to 1.6... why limit your potential customer base? While we're on the topic, I'm not particularly keen on tapestry-hibernate attempting to force a particular hibernate version. I would much rather see the hibernate dependency declared as provided (in maven parlance) and specify a version range of compatible versions.

Re: Sidepanel with pagespecific items
I'm not 100% exactly what you're trying to do but it sounds like you should make components for the bits you want to re-use and then pass a block parameter to the layout. Take a look at the RenderCommand class too. This is a way of providing markup programatically and it may make sense for you to use a RenderCommand parameter instead. You can use Tapestry's type coercion to convert from Block to RenderCommand. Inheritance is almost always a bad idea and more often than not, there is a more elegant way of doing it in tapestry. Pages and components can implement interfaces, but the interfaces MUST must not be in the pages or components packages. -- View this message in context: http://tapestry.1045711.n5.nabble.com/Sidepanel-with-pagespecific-items-tp5679939p5680458.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: Sidepanel with pagespecific items
Given your example... The Simulation and Dashboard pages could implement
PolicyProvider
Then, in your Layout
public class Layout {
@InjectPage
private Page page;
public Policy getPolicy() {
if (page instanceof PolicyProvider) {
return ((PolicyProvider) page).getPolicy();
}
return null;
}
}

Reading out a Component's formal parameters' values
Hi, I was wondering whether it's possible to read out a *Component*'s formal parameters' values? Up till now, I was only able to find the /getInformalParameter(String name, ClassT type)/ function in *ComponentResources*, which only allows to read out informal parameters. Some Context: I'd like to create a custom validator to be used in a custom component I wrote earlier. For this validator to work properly, it would need to access the values of the parameters passed to its containing component. Making the container's formal parameters informal seems like a clumsy solution.

Can Component Template be Informed by Page Class
Would like put a property in the component that will be rendered only in the
context of a page, picking up, say, a page property.
To illustrate, lets say we want Layout.tml to have the following
pseudo-html-element:
htmlelement id=${pageProperty} /
t:body /
Layout.java is empty.
Index.java:
public class Index
{
@Property
private String pageProperty= indexProperty;
}
Index.tml can be whatever, but would like to avoid putting html element in
there to avoid repetition - the htmlelement could be very big - like a menu
for the entire application, whereby the page property is used to customize
the menu for the individual pages.
Basically, is there is a way for a component to inherit properties of
child component (page)?

Re: Can Component Template be Informed by Page Class
It might be possible but it's not recommended ;) Can you just pass a property from the page to the layout? http://wiki.apache.org/tapestry/Tapestry5Layoutcomponent
Re: Can Component Template be Informed by Page Class
This may be a somewhat of a useful stand-in for the pageProperty...
${prop:componentResources.pageName}
It gets you the page name...and can be put in the component.
However, something like this would be useful
${prop:componentResources.pageName.pageProperty}
What do you guys think - JIRA worthy???

I don't think so. It violates the self-contained principle for components
very badly. Use parameters or the Environment instead.

From: http://tapestry.apache.org/link-components-faq.html Every component has an extra property, componentResources, added to it it's the instance of ComponentResources that represents the link between your code and all of Tapestry's structure around your class. . As an added benefit,* if the page class is ever renamed or moved to a different package, the pageName property will automatically adjust to the new name*. ...This is what I am talking about. -- View this message in context: http://tapestry.1045711.n5.nabble.com/Can-Component-Template-be-Informed-by-Page-Class-tp5681397p5681531.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

I totally agree with Thiago... you are trying to break tapestry's (very
sensible) principles.
Take a look at the link I sent you originally... pass a component parameter
(not a request parameter) from the page to the layout or use the
Environment.

Re: Can Component Template be Informed by Page Class
Right back at you guys on citations ;-). What principles is this breaking? BTW, I just posted a citation which describes the componentResources...which is already able to pull up the pageName...this is very useful in authoring solid code at the page level. Why would componentResources have the pagename attribute if the INTENT was otherwise (that is, as you are suggesting, the component to be oblivious to the page)? And if it does already have pageName, why not access to pageName.property? To me, it seems counter-intuitive to place a property of a page into a component and to then have it trickle back down to the page...when the component could simply access the property directly (just like it does the pageName). Also, I did review Lance's example...the images are not being pulled up, so it is a bit of a hard read. Also, it does not seem to be getting any parameters from a page. Unless... the message (best practice according to you guys) is to use the getters and setters of the component class from the page class...presumably with one of pre-rendering event handlers...which is essentially the same operation (for simple strings like ids) as request parameter...? -- View this message in context: http://tapestry.1045711.n5.nabble.com/Can-Component-Template-be-Informed-by-Page-Class-tp5681397p5681722.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: Can Component Template be Informed by Page Class
For the component to pick up page property would make it Polymorphic. Components, for instance, can then just be a shape with an abstract draw() method. The page will tell it what the shape is and what exactly the draw method will do or for that matter what those parameters are - in case of a circle it would be a radius, for rectangle - two sides etc. -- View this message in context: http://tapestry.1045711.n5.nabble.com/Can-Component-Template-be-Informed-by-Page-Class-tp5681397p5681782.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

I haven't understood what you're trying to do with it, so I didn't answer. And if it does already have pageName, why not access to pageName.property? Because they're very, very, very different stuff. Each component instance belongs to a page, so ComponentResources.getPageName() is actually an easy thing to implement. On the other hand, getting properties from the page itself is a whole different matter. In addition, tying a component to a given page is a very bad thing to do (you couldn't use the component in another page). A component accessing a page property, believe me, is a Very Bad Thing. It's bad architecture. It's going against the philosophy on which Tapestry was build. I really don't know what good would come from doing what a framework doesn't want you to do. To me, it seems counter-intuitive to place a property of a page into a component and to then have it trickle back down to the page...when the component could simply access the property directly (just like it does the pageName). That's the point: getting the page name is one thing, getting page properties would need a whole different code for it. And it would still be a very bad idea. On the other hand, you can get the page instance by invoking ComponentResources.getPage() and casting the returned object to the page class. the message (best practice according to you guys) is to use the getters and setters of the component class from the page class...

Help with Dynamic Number of Form Elements
Hello all! First time poster and rest assured that I've used the search
functionality on Nabble to see if there are similar problems to mine, and I
haven't yet stumbled across my own use case yet (and I find that to be a huge
surprise!).
Anyway, I want to state my problem in a precise and unambiguous manner so I can
help you guys help me!
Problem Statement:
loop/ constructs to not seem to make it possible to add varied numbers of
select/ elements to a form.
Use Case:
I am writing a web application that calls a SOAP service. Inside the soap
calls, I can pick from a variable number of a certain kind of information.
The information I am getting from SOAP is well ordered for use with select/
elements. Each one has an ID and a certain amount of text associated with it.
These are questions that the user will answer. The application must be
configurable viz. the number of questions that will be asked the user. Each
select/ element will have an input/ associated with it, to collect the
user's answer to the question.
Therefore, you can see how a fixed number of select/ elements is not
feasible; Some consumers of the app will want to ask the user one question,
some five! Therefore I need to be able to display a variable number of these
questions on the page.
Notes:
* I am getting the questions from a SOAP service. I don't have a
database/hibernate/JPA or anything else. Therefore all the questions for each
group are in a fixed array (or ArrayList; it does not matter at all).
* The question ID is the value for each item in the select/ with the question
text being the label I guess. Therefore, what I need to pass back is the
question ID and the user answer for each group.
End Result Desired:
* A form, with a number of paired select/ elements and input/ elements,
representing a questions asked of the user and their answer.
* The number of these pairs is not known until I query the SOAP service and
receive back a response containing a number of groups, each one of which will
be a new select/ element.
* Upon submitting the form, my application has 'n' number of questionID/answer
pairs that I then respond back to the SOAP service with.
What I have Tried:
Swing and Miss:
I created a custom SelectModel for the objects that I received from the
database. At runtime, I create one model for each group of questions I receive
from the SOAP service. I then added each of these SelectModels to an ArrayList,
making that ArrayList a @property in the class:
@property
private ListSelectModel _questionSelectModels; // This is never null; it's
populated during onPrepareForRender();
@property
private SelectModel _currentModel
Here is my Template:
form t:type=form t:id=questionsEnrollForm
loop t:source=questionSelectModels t:value=currentModel
t:formState=ITERATION
Question: select t:type=select t:id=selected t:value=selectedQuestionId
t:model=${currentModel} /
/loop
input type=submit value=submit/
/form
Result:
Exception: Render queue error in
BeforeRenderTemplate[Enroll:selectedquestionid]: Parameter 'model' of component
Enroll:selectedquestionid is bound to null. This parameter is not allowed to be
null.
Why does confusion result on my part?
* Because I assumed Tapestry would be able to iterate through the array list
-
Questions/comments:
* I am surprised that this use case has never come up; Struts, for example, has
a very elegant way of handling this (even though I hate everything else about
it)
* I know your time is valuable; I have tried to do my due diligence and have
searched the mailing list and have come up with pretty much nothing on this.
* Is it valid to attempt to iterate through a collection of SelectModel objects?
* IS there a best Practice for what I'm trying to do?
* How have others on this list handled this same use case?
* I am suspecting that I have some sort of gross conceptual error about how
this is supposed to work, but honestly for the life of me, I don't understand
where it is.
* I've combed the different tutorials avaialble as well.
* One possible area I can tell would go wrong is in the select box's value;
obviously each select/ would attempt to update the same value!
* Why is it not possible to have some sort of iterator variable to identify
what to update?
Please let me know if more source code form my end is needed to clarify what
I'm doing wrong.
Thank you so much for any help you can offer!

Re: Can Component Template be Informed by Page Class
OK. Lets leave it at that, I guess. Agree to disagree ;-). 1. Polymorphism is not about implementation at all. It is about interfaces, which is what Components can aspire to be, sort of. In that case, components, do not get tied to page properties - they use only those available - and if not, they behave as if those properties do not exist. That is Polymorphism, for me. So a shape would draw only if there was concrete draw provided, other it would ignore the draw request. 2. This discussion is about expanding horizons of Tapestry...not saying this a Very Bad Thing etc or giving up because it is difficult. That is why we can have JIRA (let it be in Version 7). Or citing some principles that are yet to be articulated fully...for all I know, we are doing that now. Basically, it is about more magic, not less functionality. 3. I see pageName is just another page property...nothing more, nothing less (or should be, if not). Therefore, all other page properties should be visible as well. Of course, I have not looked at the code... That said, THANKS, I like the idea of ComponentResources.getPage()...*may* indeed be the answer I was look for...but I am already on a roll, so perhaps will look into later and report back -- View this message in context: http://tapestry.1045711.n5.nabble.com/Can-Component-Template-be-Informed-by-Page-Class-tp5681397p5681962.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

you require.

All this theoretical discussion aside, what I am trying to do is this --

I was simplifying the discussion, but it got carried off on a different
path
Specifically, http://unraveled.com/publications/css_tabs/ CSS Tabs 2.0
We would all agree that the menu should be a component, say, Layout.tml:
body id=tab${tabId}
ul id=tabnav
li class=tab0 index?tabId=0 Home /li
li class=tab1 tab1?tabId=1 Table1 /li
li class=tab2 tab2?tabId=2 Table2 /li
[..and so on.. ]
/ul
t:body/
/body
I was struggling with where to put the tabId(X) that needs to be passed
from
page(X) to activate body id and class tab(X). Dilemma: Should the ids be
properties of each of the pages? They would then pass it to the layout
component somehow. Either by setting the component parameter tabId from
each page class or by have component read the tabId (impossible) - either
way plenty of code. Now I am just passing it as a request parameter - for
each tab. All my tabX classes are empty shells. I just need to receive it
in the component as request parameter. The Laoyout.tml code is very
readable as well.
I am not sure what the Environment solution referred really is. If you
have an example (and time!), I will be happy to consider. Even a whole new
way to do tabs perhaps? But not urgent...as I said...I have found a way
(or
a hack? Eye of the beholder ;-)).
