Okay, I've been staring at this for hours, and not making any progress.
Maybe that's because it 4:30 in the morning here in Connecticut, USA,
and my brain isn't what it should be, but regardless...
I'm attaching a class that's giving me great anguish. If anyone has a
few minutes to look at it to see if there is some glaring mistake, I
would be forever grateful. This is a view/edit class for a POJO named
Guideline, which has the following signature:
public String getDescription();
public void setDescription(String newDescription);
public String getFilename();
public void setFilename(String newFilename);
public Set getBusinessUnits();
public void setBusinessUnits(Set newBusinessUnits);
[ ... ]
The trouble is that at the end of the constructor for the inner
InputForm class, my model object has all its properties set
appropriately, but when I hit the onSubmit() method, the filename
property is correct but the description is null and the Set of
BusinessUnits is empty.
Any thoughts on what I'm doing wrong?
