Issue with Visit & PropertySelection

[Andrew Pym <ap...@goldenmean.com.au>]

I am using Cayenne within Tapestry 4 b5.

Hence I am initialising a Cayenne Datacontext object into an implementation
of Visit and then referencing that in each base page as below.

 

I was getting intermittent errors when executing in Tapestry.

It was mostly occurring after repeatedly hitting pages with multiple drop
downs.

Note I am running Tomcat 5.5.9 in jpda mode for debugging.

It is now happening all the time on a couple of pages with single drop downs
/ PropertySelection components.

 

Any ideas on what I might be doing wrong?

 

 

*******************

import au.com.goldenmean.ir.Visit;

import au.com.goldenmean.ir.dao.DAOCayenneQuery;

 

public abstract class AddEditLookUpValues extends BasePage{

 

    @InjectState("visit")

    public abstract Visit getVisit();

 

  public List getLookupObjects() {

            return
DAOCayenneQuery.getLookupTypes(this.getVisit().getDataContext());

   }

********************

 

Error at context:/WEB-INF/AddEditLookup.page, line 5, column 76: Method
'public abstract au.com.goldenmean.ir.Visit
au.com.goldenmean.ir.Pages.AddEditLookUpValues.getVisit()' (declared in
class au.com.goldenmean.ir.Pages.AddEditLookUpValues) has no implementation
in class au.com.goldenmean.ir.Pages.AddEditLookUpValues (or enhanced
subclass $AddEditLookUpValues_27). 

location: context:/WEB-INF/AddEditLookup.page, line 5, column 76

 

5<page-specification class="au.com.goldenmean.ir.Pages.AddEditLookUpValues">

I haven't actually tried injecting ASOs yet, but according to the  
User's Guide:

"The IPage interface defines two read-only properties: visit and  
global. These are both type Object. This is a holdover from Tapestry  
3.0, which only supported these two application state objects. If you  
want to access the visit or the global application state objects  
without needing casts, you will have to inject as a differently named  
property (say appVisit or visitObject)."

Could that be your problem?
