Re: custom edit page not possible
I spent the last 45 minutes installing tynamo for the first time. It's NOT
tapestry, it's a third party extension that I have never used, and I have
no idea how many people use it.
It looks like the problem is in the tynamo documentation.
To start customizing a page, make a copy of the appropriate default page
files and rename according the the table above.
If you just copy the Edit class verbatim from the archetype and create your
custom editor then you have two classes with the same routing annotation.
@At(/{0}/{1}/edit)
Your custom editor is getting into the ordered list after the base editor.
They (tynamo) have provided a way to order your routes:
@At(value = /{0}/{1}/edit, order = before:edit)
If you are going to continue to use this module then I highly recommend you
download the source and figure out how it works.

RE: custom edit page not possible
Well after tinkering and tinkering...
this works
public Object onActivate(String id)

return Utils.new404(messages);
this.bean = contextValueEncoder.toValue(beanType, id);
if (bean == null)
return Utils.new404(messages);

no annotation...
Does anyone know why ?
RE: custom edit page not possible
This doesnt work...

this.bean = contextValueEncoder.toValue(clazz, id);
this.beanType = clazz;
if (bean == null)
return Utils.new404(messages);
return null;
}
cant get a breakpoint to set here
all i did was add formal parameter Class clazz and a little usage
It is very disheartening and discouraging that at this late in these releases
that nothing is reliable or consistent or hardened.
and I am thinking if I go commercial or commit commercial with something...
where will i stand then?
it wuold be really nice if this framework and affiliates would settle down

i come from an XWindows RD in the late eighties and I developed far more

so this is what i have to go with in order to run
my beanType is hardwired to a certain class within the edit page... not my cup
of tea but I have to go with it
maybe I am just too click and go... certain things are a sealed deal and I am
inclined to set it and forget it
I want to run...actually i want to sprint... but I am tripping all over the
place
If I missed something in the docs please someone burn me to a beautiful char
i got no clue why this handler wont work if I add a formal parameter
Re: custom edit page not possible
I'd suggest you use a single activate event handler, with a signature like
this:
public Object onActivate(EventContext ec)
You can see it being used in here:
http://jumpstart.doublenegative.com.au/jumpstart/together/onepagecrud/persons
Doco is here:
http://tapestry.apache.org/component-events.html#ComponentEvents-EventContext

RE: custom edit page not possible
Thanks Geoff, I will cook down and give that a shot.
RE: custom edit page not possible
Well I cannot go with what I thought I could go with...
If I add any code to propagate logic in my page... I get different results...
which I attribute are affecting the runtime...
@Property(write = false)
private TynamoClassDescriptor classDescriptor;
@Property
private BeanModel beanModel;
@Inject
private BeanModelSource beanModelSource;
public Object onActivate(String id)
{
if (beanType == null)
return Utils.new404(messages);
this.bean = contextValueEncoder.toValue(beanType, id);
if (bean == null)
return Utils.new404(messages);
beanModel = beanModelSource.createEditModel(beanType, messages);
return null;
}
So i am thinking now it is some kind of race condition whereby my onActivate
handler doesn't get called to initialize the page to render properly.
I wish there was something I could rely on to write some reliable code.
I have already proven that I cannot incorporate a formal parameter to the above
routine or the event handler never gets called...or I think its not getting
called or its not getting called in time
I have already proven that if I add properties and injections as above and try
to use them inside the handler... the handler never gets called...or I think
its not getting called or its not getting called in time
So whats multi-threaded that could be affecting the runtime with regard to
event handlers and page rendering?
The page errors are not worth looking at because they are artificially induced
Here is the latest page error... but it is just a byproduct of the event
handler not being invoked in order to set things up.

RE: custom edit page not possible
if I comment out the lines of code...
My event handler gets invoked... and I stop at my breakpoint..
/*
@Property(write = false)
private TynamoClassDescriptor classDescriptor;
@Property
private BeanModel beanModel;
@Inject
private BeanModelSource beanModelSource;
*/
public Object onActivate(String id)
{
if (beanType == null)
return Utils.new404(messages);
this.bean = contextValueEncoder.toValue(beanType, id);
if (bean == null)
return Utils.new404(messages);
//beanModel = beanModelSource.createEditModel(beanType, messages);
return null;
}
If anyone can explain this runtime behavior I would appreciate it... a way
around it so I can code properly.
It is obvious something is wrong... either a race condition or some data/code
segment issue.
I cannot add any code for anything... otherwise my event handler never gets
called... or it gets blocked and called too late
Thanks in advance
RE: custom edit page not possible
I was able to get my java running and override a property on the BeanEditor
component
The commented out code is what prevents the event handler from being invoked...
I dont have the answer to why though

RE: custom edit page not possible
Well this doesnt work as designed/documented Customized tapestry-model templates If you don't customize anything, Tynamo uses default pages. In Tapestry, a component (a page is a component as well) is comprised of two parts: its template and a backing java class. There's a default page for each particular operation, such as: Add, Edit, List and Show. The archetype will put the Java page classes to src/main/java/groupid/pages and the corresponding templates to /src/main/webapp. The cool thing about this is that you can also customize the default look and feel of a page for an operation type. Most of the cases, however, you want to customize a page specific for a particular object. Tynamo makes decisions about what page to display based on which kind of page is needed and the class of the object(s) involved. It will first look for a page using Add, Edit, Show or List depending on the kind of page needed, prefixed with the unqualified-type name of the object. If it can't find a specific page for a given type, it will instead use the default Add, Edit, Show or List page, respectively. The following table gives some examples of how Tynamo figures out which page to use: Operation Class Look for page: If not found, use page: Edit org.tynamo.recipe.entities.Recipe org.tynamo.recipe.pages.edit.RecipeEdit org.tynamo.recipe.pages.Edit List com.foo.entities.Product com.foo.pages.list.ProductList com.foo.pages.List Add org.wwf.entities.Gazelle org.wwf.pages.add.GazzelleAdd org.wwf.pages.Add To start customizing a page, make a copy of the appropriate default page files and rename according the the table above. Most of the UI customization happens in the corresponding .tml template. Keep in mind that a Tapestry template is more or less just a html page with selected additional tags starting with t:some-tapestry-element that will be replaced by Tapestry components (which can be comprised of other templates and so forth). Read Tapestry's template guide for more comprehensive documentation. The typical customization needed for edit forms is that you want to render something else for a specific field but you are fine with other defaults. Property Editor Overrides are exactly for that purpose, see the linked documentation for exact examples. If we wanted to, we could replace the Form component entirely and create a new form from scratch using standard Tapestry components. activate handler is never invoked. I will generate a new project and try again but if I dont succeed I will file a jira ? Edit customization is what fails.
Re: custom edit page not possible
You should have mentioned before that you're trying to use Tynamo default pages. We thought it was about regular Tapestry ones, not using Tynamo, so your question is not about Tapestry itself, but about a Tynamo feature. I've never used Tynamo, unfortunately, so I can't help you here. -- Thiago H. de Paula Figueiredo - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

RE: custom edit page not possible
yikes,... sorry thiago... i thought I was replying into nother group while I got you on the line... tynamo is the better tapestry its the best code base on the planet and operated by the best developers in the world unfortunately, it lacks finish and polish and I am probably the only guy on the planet attempting to perform a custom edit page so I look like a ding dong trying to qa this thing at least I have an eye for the right stuff anyway, i would encourage you to check it out. it was invented by a benevolent engineer named chris nelson i cannot imagine building a web app without it's backing mirror capabilities chris handed it over to some open sourcee's in 2006 ... i actually was a committer to the earlier trails version it would be nice if his best intent was actualized trying to shake it out and not getting very far thanks for trying well maybe it is a tapestry problem... QUESTION: is there a way to specify an additional page directory for your tapestry app? My issue is the app does not know where to find the template... and all goes tohell
RE: custom edit page not possible
here is the actual error
An unexpected application exception has occurred.java.lang.RuntimeExceptionPage
edit/Coach did not generate any markup when rendered. This could be
because its template file could not be located, or because a render

I tried locating the template in the two above places but it still does find it.
according to tapestry docs, it is valid to locate pages beneath the pages dir
and other folders beneath
could a render phase method be tripping it up ?
