What causes Unable to read OGNL expression 'parsed OGNL expression' errors?
Could someone tell me what causes this error:
Unable to read OGNL expression 'parsed OGNL expression'
...
ognl.NoSuchPropertyException: $BasePage_0.rawDataFeedList
I'm a little confused becuase I'm getting this exception toss when it looks
like I have
everything setup correctly. I am using Tapestry 4 with Java 1.5. My Home.html
file
has the following:
tr jwcid=@For source=ognl:rawDataFeedList value=ognl:rawDataFeed
element=tr
.
and my java file looks like this:
public abstract class Home extends BasePage {
public final static String PAGE_NAME = Home;
public abstract RawDataFeed getRawDataFeed();
public abstract void setRawDataFeed(RawDataFeed aRawDataFeed);
@InjectPage(RawDataFeedAddPage.PAGE_NAME)
public abstract RawDataFeedAddPage getRawDataFeedAddPage();
@InjectPage(RawDataFeedInspectorPage.PAGE_NAME)
public abstract RawDataFeedInspectorPage getRawDataFeedInspector();
public ListRawDataFeed getRawDataFeedList() {
return getFeedManager().getManagedFeeds();
}
public IPage addFeedAction() {
RawDataFeed rawDataFeed = new RawDataFeed();
RawDataFeedAddPage page = getRawDataFeedAddPage();
page.setRawDataFeed(rawDataFeed);
return page;
}
public IPage viewRawDataFeed(String aName) {
RawDataFeedInspectorPage rawDataFeedInspector =
getRawDataFeedInspector();
RawDataFeed rawDataFeed = getFeedManager().rawDataFeedWithName(aName);
rawDataFeedInspector.setRawDataFeed(rawDataFeed.deepClone());
return rawDataFeedInspector;
}
public void deleteFeedAction(String aName) {
getFeedManager().deleteFeedWithName(aName);
try {
getFeedManager().save();
} catch (ApplicationException e) {
e.printStackTrace();
}
}
private FeedManager getFeedManager() {
return Application.sharedInstance().getFeedManager();
}
}
Looks to me like I have a getRawDataFeedList method, which should map to
ognl:rawDataFeedList.
I've tried adding a setter method (though I don't need one) but nothing changed.
Can someone explain what I'm missing?
Thanks,
Dave
Re: What causes Unable to read OGNL expression 'parsed OGNL expression' errors?
Just taking a quick stab at it... It says it can't find property
$BasePage_0.rawDataFeedList, so it looks like maybe Tapestry is using an
enhanced version of BasePage, not your Home page. Does your page
specification XML file point to your class or to Tapestry's BasePage?

RE: What causes Unable to read OGNL expression 'parsed OGNL expression' errors?
Hi,
What is in your Home.page file ?
Probably missing property name=rawDataFeed there?
Or you might want to inject the property using annotation
Good luck

Re: What causes Unable to read OGNL expression 'parsed OGNL expression' errors?
Hmmmmaybe I'm more confused than I think. Is the .page file necessary
with Tapestry 4 and java 1.5. I didn't create one and things seemed to be
working fine until I moved the project from my work PC to my home.
Does every Tapestry 4 component have to have a .page, .html, and .java
file?

No, I just assumed you had a .page file. Maybe you can whip up a small .page file real quick to see if it can find the property when you specify a page class explicitly.

RE: Hibernate and binding Exception - Unable to read OGNL expression 'parsed OGNL expression'
I'm not sure why I couldn't get the exception logged but for those who
care, the problem was a Hibernate configuration problem on my end.
eh-cache couldn't be found (I assumed jboss came with this). I used the

Yes, exactly what Jesse said. After hitting my head against the wall for two
hours I realized I was not initializing my model inside that listener.

You could put some log messages in the various getter methods to see if

they're called like a NPE.
