How do I get the ValueBinding details for a given UIComponent?
I need to get the ValueBinding details for a given UIComponent on the fly - I
wanted to write a generic method which will allow me to get the ValueBinding
details once I get the UIComponent.
Now, there is a method on the UIComponent - getValueBinding(String expr) but
it expects me to pass the expression for each of these. I do have a pattern
e.g. ID_x where x is an integer. So, this is not generic enough - is there
any way to get the ValueBinding for a UIComponent without passing the
expression and then iterate through it to get to the required ValueBinding?
Thanks in advance!

What comes to mind:
Map attributes = component.getAttributes();
for (Object key : attributes.keySet())
{
ValueBinding vb = component.getValueBinding(key.toString());
if (vb != null) ...
}

I did that earlier - should have posted this one too. I couldn't figure out
how to get the valuebinding details off it though ... Is there a particular
key I should be looking for?
Thanks in advance!

The valueBindingMap of UIComponentBase is not exposed through a method
that allows access to the keys or values, only one at a time. You can
however get access to all of the component's attributes through
"UIComponent.getAttributes() : Map".
