JComboBox doesn't show data...help please

Question

I have created a JComboBox. I place an array of strings in that jcombobox. I'm sure the data is there, however, it is not shown.
I traced the problem back to light/heavy weight problems.
When i use a lightweight JComboBox it doesn't drop down at all.
This is probably because there's a JLabel under it.
However, when i mean it an heavyweight object
(by calling PopupMenu.setLightWeightPopupEnabled(false) )
the dropdown shows up but it is empty.
Has anyone had the same problem or something similar?
help would be appreciated...
thanx.

Answer 1

Well here's a code snippet:
JPopupMenu.setDefaultLightWeightPopupEnabled(false);
Calendar cal = Calendar.getInstance();
Integer[] years = new Integer[21];
Integer[] months = new Integer[13];
Integer[] days = new Integer[32];
for(int i = 0; i < 20; i++)
years[i] = new Integer(cal.get(Calendar.YEAR) + i);
startDateYear = new JComboBox(years);
startDateYear.setMaximumRowCount(3);
Now here you see how i fillup the JComboBoxes, i've already verified that there actually are objects in the JComboBox so that's not the problem.
the first line of code is to make the JComboBoxes make a popupmenu that's heavyweight.
so it should be in front of other lightweighted components (namely a JLabel underneath the JComboBox ) .
Now i see it drop down, however it shows absolutely no data. It doesn't even show a scrollbar, you can just see gray space outline of where the dropdown menu of the JComboBox should be.
does this help?
