Hello,
I finally found what I was looking for:
Child child = new Child();
Parent parent = new Parent();
parent.setName("test");
child.setParent(parent);
String prop = "parent.name";
boolean goon = true;
Object aObject = child;
while (goon) {
int indexOf = prop.indexOf(".");
String nextprop = null;
if (indexOf < 0) {
goon = false;
nextprop = prop;
} else {
nextprop = prop.substring(0, indexOf);
prop = prop.substring(indexOf + 1);
}
aObject =
FacesContext.getCurrentInstance().getApplication()
.getPropertyResolver().getValue(aObject,
nextprop);
}
String aString = (String) aObject;
aString.equals("test") == true!
It would just be nice if there was an existing method
which is already doing the while loop, like:
String aString = (String)
...resolveEverything().getValue(child, prop);
Regards
René

Hi Rene,
what do you mean by "in a non JSF context"? If you mean
in your
managed beans, you can do:
FacesContext.getCurrentInstance().getApplication().getVariableResolver().resolveVariable(FacesContext.getCurrentInstance(),"exprString");
If you mean general expression resolving, you might want
to use the
commons-el package directly.
regards,
Martin

Hello,
I would like to make use of JSF EL in a non JSF context.
I
d like to do something like:
String name = (String) EVALUATE(child,
"child.parent.name") instead of
String name = child.getParent().getName();
Probably there is somewhere the EVALUATE method I am
looking for. Anyone knows where?
Thanks
René
