WebColumnCombo value removed

[jcachia]

Hi all,

I have a WebColumnCombo (oBenRelationCol) which is being populated through a webservice.
I am able to select the values and everything is working as it should.

However when I click back on a row which had the value selected, the value in this WebColumnCombo is removed.

In the same WebList, which has no databinding, I have another WebColumnCombo which is being populated manually by the AddComboItem and is working properly.

                Object oBenRelationCol is a cWebColumnCombo
                    Set psCaption to "Relation"
                    Set piWidth to 20
                    Procedure onFill
                        Forward Send OnFill
                        Integer iNum i
                        //
                        Get wsGetListofRelations of oWsInternal to mBenRelationList 
                        //
                        Move (SizeOfArray(mBenRelationList)) to iNum
                        //
                        For i from 0 to (iNum-1)
                            Send AddComboItem mBenRelationList[i].sRelation mBenRelationList[i].sRelation
                        Loop                
                        //
                    End_Procedure                      
                End_Object
                
                Object oBenGenderCol is a cWebColumnCombo
                    Set psCaption to "Gender"
                    Set piWidth to 20
                    Procedure onFill
                        Forward Send OnFill
                        //
                        Send AddComboItem "<Undefined>" "<Undefined>"                                                                        
                        Send AddComboItem "M" "Male"
                        Send AddComboItem "F" "Female"
                        //
                     End_Procedure                    
                End_Object

Thanks in advance.
