Hi Jeff,
I know this thread is little bit old, but i just stumbled upon the same
issue raised here. And the interesting part is that i have a Bean property
set as java.util.Set (we are using Java 5 Generics).
Secondly i do not get java.lang.ClassCastException or any other exception.
It just goes through but could not save the records as it does not get
casted to Set.
e.g :
if (product.getItems().size() > 0) {
LOG.info("Product.getItems().size() is " + product.getItems().size());
// i am getting size as one which is ok
Set entries = product.getItems();
Iterator entriesIter = entries.iterator();
Items items = null;
while (entriesIter.hasNext()) {
// does not enter while loop and thus no records saved for Items
saveOrUpdateAll(product.getItems());
}
}
Any idea why the Items are not getting casted to Set.
Thanks,
Sudhan
