[NewB] Separating the ValidatorBean from the Page.app
Hi all
I'm playing around the excellent Enjoying Web Development with
Tapestry pdf and I would like to do a variation around the
ValidatorBean.
In the example page 77, the PatronCodeValidator class and the Home
class are in the same folder. I was trying to put the
PatronCodeValidator somewhere else, for example :
<page-specification class="pages.Home">
<bean name="patronCodeValidator" class="validator.PatronCodeValidator">
<set name="knownPatrons" value="ognl:knownPatrons"/>
</bean>
(...)
</page-specification>
However, it doesn't work, I get this error :
"org.apache.hivemind.ApplicationRuntimeException
Error initializing property knownPatrons of bean 'patronCodeValidator'
(of component Postage): Unable to read OGNL expression '<parsed OGNL
expression>' of $Postage_11@198046[Postage]: $Postage_11.knownPatrons"
SoMy questions are : is it possible to have the Validator in another
package than the one where the page's class is ? If yes, how ?
Thanks in advance
ZedroS

Thanks for your answer Matt. As soon as I have finish my current work on a
Spring/Struts website, I'll happily use your advice :)
Thanks again

The error indicates that OGNL cannot read the knownPatrons property.
Make sure you have this property defined in the page. If you want to
access a property from multiple pages you can define it in a singleton
and access it statically like:
ognl:@com.ttdev.postage.KnownPatrons@getInstance()
When you get to chapter 4 you will see a better way of doing this:
Application State Objects.
