javax.el.ListELResolver.isReadOnly

[Violeta Georgieva <mi...@gmail.com>]

Hi,

In the javadoc it is not described that the method throws IAE when the
property cannot be coerced into an integer. Moreover it is specified that
the property will be ignored by the resolver:

"
property - The index of the element in the list to return the acceptable
type for. Will be coerced into an integer, but otherwise ignored by this
resolver.
"

Should we return the corresponding readOnly result and not throw IAE?

Thanks
Violeta

If it is a non-integer property, just ignore it.

For example, in Javascript a list has both indexes and a "length"
property. The "length" property should be silently ignored by
ListELResolver. It is the task of other resolvers (e.g.
BeanELResolver) to handle it.
