Valiantsin Shukaila commented on RF-11469:
------------------------------------------
I am having such problem with 4.3.1 version of Richfaces.
The Problem is that by default autoCompleteMethod seems to be defined with 3
parameters: FacesContext,UIComponent,String.
This can be seen from here:
{code}
try {
// String value = getInputValue(facesContext, component);
itemsObject = autocompleteMethod.invoke(facesContext.getELContext(), new
Object[] { facesContext, component, value });
} catch (MethodNotFoundException e) {
ExpressionFactory expressionFactory =
facesContext.getApplication().getExpressionFactory();
autocompleteMethod =
expressionFactory.createMethodExpression(facesContext.getELContext(),autocompleteMethod.getExpressionString(),
Object.class, new Class[] { String.class });
itemsObject = autocompleteMethod.invoke(facesContext.getELContext(), new
Object[] { value });
}
{code}
One can see that if method with 3 arguments is not found(actually it is not
clear why it is 3 arguments, they are useless) just exception is caught and new
MethodExpression is created. But this new MethodExpression doesn't take in
account all facelet compositions so beans passed as parameters would not be
resolved in this new method expression.
So I see the easiest workaround for this: change method declaration in the bean
so that it would have 3 arguments (FacesContext, UIComponent, String).
For me this worked well.
Actually it's a pity that almost 2 years passed after this issue was found and
it is still not resolved. Actually I have such a bad feeling with all richfaces
4 version. Seems nobody supports it now?
