Could not find a coercion from type java.lang.String to type
com.****.lighting.guidecontrol.view.BreadcrumbBean
Hi,
Just to make sure I'm not missing something.
In T4 when I wrote a @For construct I could use value="..." as long as I
provided a setter|getter pair for the class involved - in this case
BreadcrumbBean. I want to iterate over a list of beans and use each
instance individually. Now T5 throws up on me with this nice coercion
message. Does this mean I need to contribute my own coercion - or is
there a more simple way? In my case BreadcrumbBean is a simple class
holding three String members.
Thanks (again :-))
-J.

_that sounds like a bug to me. It should stay as an Object, and since its
not rendered, shouldn't need to string-itised.
http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry/corelib/components/Loop.html
value type is Object
weird... so far I've only looped enums, so I wouldn't know.
perhaps someone who knows about the internals ?

RE: Could not find a coercion from type java.lang.String to type
com.****.lighting.guidecontrol.view.BreadcrumbBean
Posted by "Blower, Andy" <An...@proquest.co.uk>.
I think I encountered the same issue last week where I wanted to loop over a List of objects that were instances of one of my own classes. The loop component code finds it necessary to be able to convert the object into a string and then back again when populating your value property variable from the element of the list.
The reason for this appears to be something to do with forms and volatility, but I really don't understand those issues at all. (Note: it would be *fantastic* if someone could explain the concepts behind forms and volatility because it's not clear to me from the T5 documentation)
Instead of creating a coercer for my class, which I had no desire to do as this loop was not part of a form, I made my own component handle the looping/iteration. I could have made a non-coercing generic loop component, but as I was already creating a component whose template just needed a loop in, I just used that component.
I don't know what the general thought is about the loop component, but having to coerce each element to a string for form support seems to me to be more applicable to a special case of loop than a generic loop. But I'm very new to Tapestry so I might be getting this all wrong.
Does that make sense?

Without having read this thread carefully I suggest that you try to add
volatile="true" to your loop.

RE: Could not find a coercion from type java.lang.String to type
com.****.lighting.guidecontrol.view.BreadcrumbBean
Posted by "Blower, Andy" <An...@proquest.co.uk>.
Me too Jan, thank you.
I was also passing a list via the template loop component attribute 'source' as well, and I was also wrapping it with ${} - I've obviously spent too long using the JSP EL! This would be a good gotcha to add to the wiki or even possibly the T5 documentation...?
Anyway it looks like I was completely wrong about the loop component then. I could still use an explanation of volatility & forms though if anyone can point me in the right direction.

Re: Could not find a coercion from type java.lang.String to type
com.****.lighting.guidecontrol.view.BreadcrumbBean
Posted by Chris Lewis <ch...@bellsouth.net>.
Ok I think I see the problem. In your layout replace this:
t:breadCrumbs="${basePage.breadCrumbHolder.model}"
with this:
t:breadCrumbs="basePage.breadCrumbHolder.model"
Notice the lack of ${}. ${} is trying to convert it to a string, which
it's not. When passing params to components you don't use expansions,
what you want is the object property from the class. The default binding
prefix for params is "prop" which is what you want in this case.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Using the default @Parameter, this should just be:
t:breadCrumbs="basePage.breadCrumbHolder.model".
Default binding type is "prop", so the ${} bit is unneeded.
If your loop is in a form, then you should pass "volatile=true".

Posted by Jan Vissers <Ja...@cumquat.nl>.
I think I'm getting a bit further now - sorry to spam this list by the
way...
If I pass the breadCrumb model in the Component class instead via the
Component Template something is happening.
So instead of:
<t:heading t:id="heading"
t:breadCrumbs="${basePage.breadCrumbHolder.model}" />

Re: Could not find a coercion from type java.lang.String to type
com.****.lighting.guidecontrol.view.BreadcrumbBean
Posted by Jan Vissers <Ja...@cumquat.nl>.
I'm deeply sorry for keeping you guys busy, and really appreciate the
feedback. But I nailed it. It had to do with the way I'm passing the
model. Via the Layout class it works, but not so via the Layout
template. I'm sure (am I?) that this is by design of T5 - so sorry for
any inconvenience.

Wow this is a bit tangled. I remember this from the other thread now( [
BasePage -> Layout -> RealPage ] ). I don't mean to jerk you around, but
can you provide the exception report page? I think if we can see the
line causing this as well as the stack trace, we can nail down where T5
is expecting something it's not getting.

Re: Could not find a coercion from type java.lang.String to type
com.****.lighting.guidecontrol.view.BreadcrumbBean
Posted by Jan Vissers <Ja...@cumquat.nl>.
In the snippet below if I change:
public List<BreadcrumbBean> getBreadCrumbs()
and let it return a freshly created list. The loop construct works.
However via the @Parameter (passing it it) doesn't.

We still haven't seen your template code, where you declare this
component and pass it the model. I can't be sure but perhaps it will
shed some light...

Re: Could not find a coercion from type java.lang.String to type
com.****.lighting.guidecontrol.view.BreadcrumbBean
Posted by Jan Vissers <Ja...@cumquat.nl>.
The problem is somehow related to the way my page and component are
hooked up/working.
For testing purposes I now create the Breadcrumb list in the component
itself, simply returning a created list on the fly whenever
getBreadCrumbs() is called. This works as expected!!!
Strange thing is that via passing the 'model' to the component via a
page binding the same thing doesn't work. This must be a bug?!

That looks good to me. I don't have an example I can look at with a
loop, but I do have one with a t:grid in which I reference a bean
property of a custom class. It's possible that the two are vastly
different, but I wouldn't think that.

Re: Could not find a coercion from type java.lang.String to type
com.****.lighting.guidecontrol.view.BreadcrumbBean
Posted by Jan Vissers <Ja...@cumquat.nl>.
On the component I have:
@Parameter
private List<BreadcrumbBean> breadCrumbs;
This is passed in via the containg (base)page.
And in the same component class I have:
private BreadcrumbBean crumb;
public BreadcrumbBean getCrumb() {
return crumb;
}
public void setCrumb(BreadcrumbBean crumb) {
this.crumb = crumb;
}
This should be right, right?

? is your crumb property of type BreadCrumbBean, or is it type String?
should be same as breadCrumbs<?TYPE>

I can't speak about your t:if bit because I don't know what "LastCrumb"
would be, but assuming that your page class has getters/setters (or the
property is annotated with @Property) for the "crumb" property, a getter
for your "breadCrumbs," and your crumb bean defines a "getName" method,
you *should* be good.
It would be helpful if you can include the exception, specifically the
line it references, etc.
