Upgrading to 2.4 alpha 5 (from 2.2)
well, it has been a while since I've had the chance to do any Tapestry
stuff, but I found time this weekend!
So, time to upgrade from 2.2 to 2.4.
I've got the following page specification (partial):
<component id="editJobName" type="Contrib:ValidatingTextField">
<string-binding name="displayName" key="jobNameLabel"/>
<binding name="displayWidth" expression='40'/>
<binding name="minimumLength" expression='1'/>
<binding name="required" expression='true'/>
<binding name="text"
expression='getEngine().getVisit().getJobBeingEdited().jobName'/>
</component>
Yet when the page is rendered, I get the exception detailed below.
Seems to me that there is a problem calling the setValueBinding in the
enhanced class, but I don't know why.
I'm not sure if it's being caused by an NPE (perhaps the visit is null?)
or if it's a syntax issue? (ognl upgrade...) or why....
I'm a little confused :-)
Can anyone give me some pointers of what to look for, especially since
this is not new code, but code that used to work on Tapestry2.2.
In terms of "upgrading", all I've done is fixed all the package names,
and modified the app specification with an updated property for the
visit class (it changed when the package name change was done).
also, is there any way to get hold of the autogenerated class files?
I've done a brief search over the news postings, but didn't see
anything. I'm guessing not, since the're generated at runtime...
Regards,
Neil Clayton

Could be....
When using 3.0 (from CVS HEAD), I get:

I have to disappear to work, so this *could* be due to something I've
done (well, being in the ValidatingTextField, perhaps not :-), I've lont
looked really closely at this yet - just thought I would post the info
for others + mb.
Have a happy day :-)

I'm pretty certain that this is a real bug; I got the NumericField component (and friends) to
compile, but never figured out if they actually worked under the new system.

Hash: SHA1
mines defined as 'Contrib'.
also, the stacktrace shows code entering the ValidatingTextField instance, so
it's obviously finding it.
I've verified that the visit object is not null (it is used before I click the
button which causes this trace)
it's almost as though the binding is read-only.
If it helps, the code that spawns this event is as follows:
try {
getPage().getEngine().forgetPage("JobEditor");
getState().setJobBeingEdited(ObjectFactory.getFactory().getJobWithName(jobName));
cycle.setPage("JobEditor");
} catch (FactoryException e) {
throw new ApplicationRuntimeException("Unable to find the job with name " +
jobName, this, e);
}
this is kicked from from within a Submit listener method.
getState() just returns the current visit object (correctly cast). The
variable jobName is already initialized to be "the right thing".
