Re: Tapestry 5.1 exception "Could not find a coercion from type ..." on form submit
Hi,
There was a change from using pkencoder to valueencoder (it's noted in
the upgrade notes) in 5.1 for loops contained in forms.
See: http://tapestry.apache.org/tapestry5.1/upgrade.html
Particularly, the section:
"Release 5.1.0.0
Primary Key Encoder
This is the change between releases that is most likely to affect your
upgrade."

Hi everyone. We just started migration from tapestry 5.0 to 5.1 and
found a
lot of strange exeptions. Here is one of them.
page class:
public class Test {
@SuppressWarnings({"unused", "UnusedDeclaration"})
@Component(id = "form")
private Form form;
@Property
private SomeClass someClass;
@Property
private SomeClass[] someClasses = {new SomeClass("1"),new
SomeClass("2"),new SomeClass("3"),new SomeClass("4"),new
SomeClass("5")};
public class SomeClass
{
private String s = "SomeClass ";
public SomeClass(String s)
{
this.s += s;
}
public String toString()
{
return s;
}
}
}
tml file:
http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";>
${someClass}
Works fine unless you try to submit form. It throws something like
that:
Caused by: java.lang.IllegalArgumentException: Could not find a
coercion
from type java.lang.String to type ru.kupivip.pages.shop.Test
$SomeClass.
Available coe
rcions: Double --> Float, Float --> Double...bla bla bla...
It can be solved by not-so-good-looking-code like this:
private SomeClass someClass;
public Object getSomeClass()
{
return someClass;
}
public void setSomeClass(Object maybeSomeClass)
{
someClass = maybeSomeClass != null && maybeSomeClass instanceof
SomeClass
? (SomeClass) maybeSomeClass : null;
}
I've debugged the setter ant it seems that it is called 2 times:
1st time after onActivate phase
2nd time after onSubmit/onActivate
and 1st time the argument maybeSomeClass is not instance of
SomeClass but
its toString() value!

Page.tml has ComplexComponent and passes to it block (="decorator") by "titleDecorator" parameter. Inside ComplexComponent template, there is Decorate component surrounding part of template. "Decorator" from "titleDecorator" parameter is passed by "by" parameter to Decorate. Responsibility of Decorate component is to render its body inside block (="decorator") passed by "by" parameter.

Great thread and I'm really not trying to take away from the momentum - but per this last idea ... I'd keep in mind that the one of Tapestry's goal is to increase marketshare. I'd suggest that, while Javascript agnosticism may not be the top priority amongst *current* users, I think that in general, it ranks up there (along with documentation) as being pretty important going forward. It is really quite an integral part of anything Web 2.0ish. < $0.02. -Luther

Thanks guys.
If anyone is interested, I'll be documenting my progress here:
http://piraya-blog.blogspot.com
Current status: I have a web-project up and running and I'm able to switch
between Prototype-mode and Non-prototype-mode (which leaves out the
prototype libraries).
$('elementId').activate is now Tapestry.activate('elementId') which means
the first bit of Prototype-specific code is converted to plain Javascript.

[Tapestry Central] Back from Tapestry 5 Training / Madison, WI
Just got back last night from training in Madison WI. This was primarily an intro to Tapestry 5 for Tapestry 4 developers (and a couple of new-to-web-programming developers) and a lot of hands on pair programming to get them going with their conversion work. It was a lot of fun, and as usual, I learned a bit. I have a couple of weeks respite now before OSCON which will be followed with training in York, UK, then Estonia, then London. I'm continuing to hold off on code changes to Tapestry 5, though I hit enough minor annoyances that I'm considering a 5.1 bug fix release before starting 5.2 in earnest. I have a backlog of work related to Tapestry360 and then my main emphasis is going to be Documentation, Screencasts, Articles, Documentation and Documentation, plus some additional Documentation. It may be a while before I start with new features for 5.2. -- Posted By Howard to Tapestry Central at 6/12/2009 12:56:00 PM

T5 enhancement: Redirecting from ComponentEventLinkEncoder.decodePageRenderRequest()
I recently moved authentication for our project in method advice for the
ComponentEventLinkEncoder method decodePageRenderRequest() because some other
method advice to the same method has some modified URL processing and it saves
duplicating it in an authentication dispatcher. In some situations this method
advice needs to redirect to a single sign on server rather than render a page,
so I have had to override the standard T5 PageRenderDispatcher to allow this.
Does anyone else think this is more generally useful and might be a good
enhancement to the standard T5 PageRenderDispatcher? Or is this a very specific
edge case? I'm tempted to raise a JIRA issue, but thought I'd test the water
first.
The code uses an extension of EmptyEventContext called RedirectEventContext to
indicate a redirect should take place (bit of hack to avoid API change) and
looks like this:
public boolean dispatch(Request request, Response response) throws IOException
{
PageRenderRequestParameters parameters =
linkEncoder.decodePageRenderRequest(request);
if (parameters == null) return false;
if (parameters.getActivationContext() instanceof
RedirectEventContext) // New block
{
response.sendRedirect(parameters.getLogicalPageName());
return true;
}
componentRequestHandler.handlePageRender(parameters);
return true;
}

Modify 'title', 'rel'... attributes on link html element.
Hello, Yesterday I discover the ClientInfrastructure service and how easy it is to add our own resources on the Tapestry5 CSS and JS stack. But I need to add a title on some of my css links, and it was frustrating not being able to achieve this in a simple way, idem with the 'rel' attribute which is set in the "IncludedStylesheet" class that has package visibility and is declared as internal. I end up by modifying the 'link' using a MarkupRendererFilter and the MarkupWriter class. Did I miss something ? Thanks in advance, Christophe.

Tapestry 5.1 exception "Could not find a coercion from type ..." on form submit
Hi everyone. We just started migration from tapestry 5.0 to 5.1 and found a
lot of strange exeptions. Here is one of them.
page class:
public class Test {
@SuppressWarnings({"unused", "UnusedDeclaration"})
@Component(id = "form")
private Form form;
@Property
private SomeClass someClass;
@Property
private SomeClass[] someClasses = {new SomeClass("1"),new
SomeClass("2"),new SomeClass("3"),new SomeClass("4"),new SomeClass("5")};
public class SomeClass
{
private String s = "SomeClass ";
public SomeClass(String s)
{
this.s += s;
}
public String toString()
{
return s;
}
}
}
tml file:
http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";>
${someClass}
Works fine unless you try to submit form. It throws something like that:
Caused by: java.lang.IllegalArgumentException: Could not find a coercion
from type java.lang.String to type ru.kupivip.pages.shop.Test$SomeClass.
Available coe
rcions: Double --> Float, Float --> Double...bla bla bla...
It can be solved by not-so-good-looking-code like this:
private SomeClass someClass;
public Object getSomeClass()
{
return someClass;
}
public void setSomeClass(Object maybeSomeClass)
{
someClass = maybeSomeClass != null && maybeSomeClass instanceof
SomeClass
? (SomeClass) maybeSomeClass : null;
}
I've debugged the setter ant it seems that it is called 2 times:
1st time after onActivate phase
2nd time after onSubmit/onActivate
and 1st time the argument maybeSomeClass is not instance of SomeClass but
its toString() value!

Re: Two Menu Components
Oops, sorry. My bad.
This doesn't work with components in this way.
If you want to update with Ajax I suggest you try donf jangs solution. The
following works on full page refresh.
You need to have MainMenu and SideMenu as components in your Layout.java
Layout.java
@Component
private MainMenu mainMenu;
@Component
private SideMenu sideMenu;
Object setupRender()
{
sideMenu.setSelectedMainMenuItem(mainMenu.getSelectedMenuItem());
return null;
}
MainMenu.java
@Persist
private String selectedItem;
@Property
private List menuItems = Arrays.asList("home", "about", "help");
@Property
private String currentMenuItem;
public String getSelectedMenuItem()
{
return selectedItem;
}
Object onActionFromMyMenu(String context)
{
selectedItem = context;
return null;
}
MainMenu.tml
...
${message:${currentMenuItem}-label}
MainMenu.properties
home-label=Start
about-label=About
help-label=Help
SideMenu.java
@Persist
private String selectedMainMenuItem;
public getSelectedMainMenuItem()
{
return selectedMainMenuItem;
}
public setSelectedMainMenuItem(String value)
{
selectedMainMenuItem=value;
}
The rest with the blocks can stay as it is in the first post.
If you don't write explicit getters and setters like I did in this second
example, it won't compile, since the getters and setters are only created at
runtime by Tapestry when using the @Property annotation. Sorry for being so
rash. I hope this helps, and as I said if you want Ajax, look at donf yangs
code.

Tapestry working with ZK component
Hi,
I played a little bit with ZK and Tapestry this morning and I achieved
something quite nice : I succeeded in inserting a ZK component in
Tapestry page, and this component can call Tapestry actions.
Here is how to do it :
1) Install ZK :
2) The Tapestry Component that allows including any ZK component :
public class ZkComponent {
@Parameter(required = true, defaultPrefix = BindingConstants.LITERAL)
private String name;
@Inject
private RequestGlobals requestGlobals;
@Inject
private ComponentResources resources;
boolean setupRender(MarkupWriter writer) throws ServletException,
IOException {
HttpServletRequest request = requestGlobals.getHTTPServletRequest();
HttpServletResponse response = requestGlobals.getHTTPServletResponse();
request.setAttribute("resources", resources);
request.setAttribute("id", resources.getId());
CharResponseWrapper body = new CharResponseWrapper(response);
request.getRequestDispatcher(name + ".zul").include(request, body);
writer.writeRaw(body.toString());
return true;
}
public class CharResponseWrapper extends HttpServletResponseWrapper {
private CharArrayWriter output;
public String toString() {
return output.toString();
}
public CharResponseWrapper(HttpServletResponse response) {
super(response);
output = new CharArrayWriter();
}
public PrintWriter getWriter() {
return new PrintWriter(output);
}
}
}
3) Use in Tapestry page :
This will insert the test.zul component
4) ZK component with the Tapestry call :
This component is a button. When you click on it, it fires an event to call the
Tapestry action displaying a JSONArray("This is a test : ", param); param
beeing the button name.
import org.apache.tapestry5.ComponentEventCallback;
import org.apache.tapestry5.ComponentResources;
import org.apache.tapestry5.internal.util.Holder;
ComponentResources resources = execution.getAttribute("resources");
// Get button with id
String id = execution.getAttribute("id");
Button btm = spaceOwner.getFellow(id);
void sendEventOnAction(){
Object result = onAction();
alert("result = " + result);
btm.label="ok";
}
Object onAction() {
// Manage trigger result
final Holder holder = Holder.create();
ComponentEventCallback callback =
new ComponentEventCallback() {
public boolean handleResult(Object result) {
holder.put(result);
return true;
}
};
// Run event
resources.triggerEvent("action", new Object[] {btm.label},
callback);
return holder.get();
}
5) Tapestry action
Object onAction(String param) {
return new JSONArray("This is a test : ", param);
}
I also tried with different ZK components, it seems to work pretty fine.
I hope this can help some people.
Best Regards,
Julien & Jean for translating :D

T5.1: Palette causing a NPE upon form submit
I've been trying to figure this out for a few hours I've got a strange issue with the Palette component causing a NullPointerException upon form submit, but only on form failure involving server-side validator's such as the email validator (i.e. the form is submitted - onSubmit called but onSuccess not called due to errors, and are displayed). I'm using Tapestry 5.1.0.5 Background: I'm using Palette within a BeanEditForm when editing a User instance to edit a list of groups (List) to which the user belongs (a many-to-many relationship - I'm using Spring + Hibernate). The NPE is only thrown when submitting form with errors that are not catched by the JS validators, and are processed on the server, such as the email validator. Also, the NPE is only thrown if there are some groups on the "selected" side. Here's the first line from the stack trace: Render queue error in org.apache.tapestry5.internal.structure.renderphaseeventhandle...@79a340: java.lang.NullPointerException Here's the palette declaration: The user instance is persisted in the page class, and is initially populated in onActivate: @Property @Persist private User user; The selectGroups property, which is used for both model and encoder, is initialized in page's onPrepare with each request. It is a GenericSelectModel instance. That said, the palette component works properly almost all the time. When I edit a user instance, set all fields, select the groups and save, it all works. It only fails with the NPE when I leave out the email field, causing the server-side validation to display an error in . I've tried to add logger statements to the getter for selectGroups, and whenever it is actually called, both the selectGroups collection and user.groups collections are non-null and properly populated. So I have no idea what might be causing the NPE? Any hints are highly appreciated! Below is a longer snippet from the stack trace.

Create an eventhandler in your MainMenu component which fires on select

Dynamic grid editable
Hi,
I try to do an dynamic editable grid, that means that I want to create a
grid that will be able to display and edit a set of data which name, type
and structure are unknown at compilation time. My need is that my grid
should be able to dynamically detect on runtime the type and the structure
of data and adapt its rendering and its behavior depending on that
structure.
I have this code to add dynamically column of my grid:
this.gridModel =
this.beanModelSource.createDisplayModel(Feature.class, this.messages);
this.cleanBeanModel();
for (LayerAttribute attribute : this.attributes) {
if (attribute.getReadAccess()) {
if (logger.isDebugEnabled()) {
logger.debug("Adding property to grid model : " +
attribute.getLabel());
}
PropertyConduit conduit =
this.propertyConduitFactory.getPropertyConduit(
attribute, this.messages);
PropertyModel attributeModel =
this.gridModel.add(attribute.getName(), conduit);
attributeModel.label(attribute.getLabel());
}
}
it works well.
now I want to configure the cell renderer of my grid , by default is a
I want to transform to or other tag, in order to transform my grid
to editable grid.
the only way , I find a solution using a component but my
columns are added dynamically and the name and type of all columns are
variable and unknown so I cannot use it.
Do you think how such a component could be implemented and how ? How I can
change this cell renderer ? Is there a solution to dynamically create and
add t:parameters or similar components in Java to construct my grid
rendering ?
Many Thanks,
Regards,
