Thanks Barry, the squeezer now works, but now I am having problem passing
the object to and from component on the page. Becouse the error is so weird,
I conclude something is wrong with component parametrs not being properly
handled. It works without the component. Page includes component
<component id="categoryBox" type="CategoryBox">
<binding name="category" value="category"/>
<binding name="children" value="children"/>
<binding name="listener" value="listeners.onClickCategory"/>
</component>
The component gets a list (children) which are value objects registered for
squeezing and their parent (category - also the same type) and should
display a list of their names. When a child category is clicked the
component sends a message through listener to the page that contains it to
invoke
public IPage onClickCategory(CategoryVO categoryVO) {
WizardStep2 wizardStep2 = getWizardStep2Page();
wizardStep2.setCategory(categoryVO);
return (IPage) wizardStep2;
}
which should display children's children, but instead I am getting the
Could not load class com.package.ClassName from WebappClassLoader delegate:
false repositories: /WEB-INF/classes/ ----------> Parent Classloader:
[EMAIL PROTECTED] :
com.package.ClassName
In my
public Collection getChildren() {
logger.info("get children of " + getCategory());
Collection children = getManager().getChildren(getCategory(), null);
logger.info("= " + children);
return children;
}
page class method getCategory() returns null. The setter and getter are
defined
abstract public CategoryVO getCategory();
abstract public void setCategory(CategoryVO categoryVO);
Advice appreciated!

Here is mine. Just add the state manager as a property and pull out
what you need.
public Object unsqueeze(DataSqueezer squeezer, String string) {
try {
Repository repository = (Repository)
stateManager.get("repository");
User user = (User) stateManager.get("user");
return repository.select(user, new Long(
string.substring(1)));
} catch (NumberFormatException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
private ApplicationStateManager stateManager;
public void setStateManager(ApplicationStateManager stateManager)
{
this.stateManager = stateManager;
}
}
