Tapestry uses a pool to store page instances. While rendering it is safe
to use instance variables but you have to make sure they are reset,
preferrably in either pageDetached or pageAttached events.
If you don't reset them, information can be shared between many users of
your site, but not by all, since they might get another instance from
the pool.
When using abstract properties, tapestry does the initialization work
for you.
Hope that helps,
Ron

Sorry. What I mean by does not work is that getLocationOfStore() in my
component is null after the component renders.
When I use the updated code below the storeLocation is passed through to
the component and getLocationOfStore() contains the location I passed in
from the page.
It does not like it when I use abstract getters and setters but I dont
understand why.
Thanks

Hi,
I am having problems binding a property on my page to a parameter in
my component. The following does not work
can you be more specific. "Does not work" is somehow general...
I have a CategoryListComponent as follows
<component id="categoryListComponent" type="CategoryListComponent">
<binding name="locationOfStore" value="storeLocation"/>
</component>
On my CategoryList.java I have
public abstract void setStoreLocation(Location storeLocation);
public abstract Location getStoreLocation();
If however I change it as follows, it works fine. The storeLocation
is passed into the component.
<component id="categoryListComponent" type="CategoryListComponent">
<binding name="locationOfStore" value="locationOfStore"/>
</component>
On my CategoryList.java this time I have
private Location locationOfStore;
public void setLocationOfStore(Location locationOfStore) {
this.locationOfStore = locationOfStore;
}
public Location getLocationOfStore() {
return locationOfStore;
}
I dont understand why the Location wont be passed through if it
declared as abstract. Any help would be great
Regards
Brian
