Problem in refreshing the combo box on selection of an item in another comb

Question

I have a situation where values to be displayed in 2nd combo box depends on the selection of an item from the 1st combo box.
Problem observed:
The 2nd combo box is not getting refreshed if the selected item from the 1st combo box has mapping to more than 10 items.
for ex:
A - AA, AB, AC, AD, AE, AF
B - BA, BB, BC, BD, BE, BF, BG, BH, BI, BJ, BK, BL, BM, BN, BO, BP
C - CA, CB, CC
D - DA, DB, DC, DD
1st combo box list:
A
B
C
D
2nd combo box list:
If the value selected from the first combo box is A, C, or D then 2nd combo box refreshes with repective values. But when the value selected is B, then 2nd combo box is not getting refreshed with respective values.
Combo Model for 1st combo box:
public class proCLMLossTypeComboModel implements javax.swing.ComboBoxModel
package nz.co.towerinsurance.quantum.claims.pro;
import javax.swing.*;
import java.util.*;
import CoreProduct.mbsoPRDLossCauseTypeList;

return this.vector;     
Combo Model for 2nd combo box:
