Thanks for your help Nico,
As you recommend I've checked into my ObjB class and the property "prop"
looks well formed :
- "prop" is of type String
- there is only one getter (getProp() ) and one setter (setProp(String p) )
- getProp() is public
As I mentionned in my first append, I used two ways to code the
logic:iterate tag.
I can understand the first error message as there is no mention anywhere of
the type of "objB" (as "objB" is stored as an Object type in the
Hashtable). But I don't understand the second error message ("invalid Cast")
as I specify the type for "objB".
