Hi All,
I was wondering if there was a way to determine if a given expression is valid
for a particular type.
i.e. if the properties/methods specified actually exist.
Something along the lines of Ognl.isValidExpression(Root.class,
"root.branch.leaf")
e.g.
class Branch {
public Leaf leaf;
}
class Root {
public Branch branch;
}
Note that I don't need/want to pass in an instance to evaluate getValue on, I
just want to know if "root.branch.leaf" is valid.
I tried passing in a new instance of the type but then I was getting the
following error:
ognl.OgnlException: source is null for getProperty(null, "leaf")
Thanks,
Frank Grimes
