EJB/JPA Related: Objects are not going to delete from a Collection

Question

Hi All,
I am developing a WebDynpro application using EJB3 model with JPA as a persistence tool. I have mapped using Annotations.
All other works run fine but If I deleted a record through view It will not delete from database.
I have two entities : First : OperationDayWorkingCapitalPlan in which following relation is defined:
     @OneToMany(mappedBy="operationDayWorkingCapitalPlan",targetEntity=BranchPartyCollectionsPlan.class,
       fetch=FetchType.EAGER, cascade=CascadeType.ALL)
     private Collection<BranchPartyCollectionsPlan> branchPartyCollectionsPlans = new  
       ArrayList<BranchPartyCollectionsPlan>();
related methods:
     public Collection<BranchPartyCollectionsPlan> getBranchPartyCollectionsPlans() {
          return branchPartyCollectionsPlans;
     public void setBranchPartyCollectionsPlans(
               Collection<BranchPartyCollectionsPlan> branchPartyCollectionsPlans) {
          this.branchPartyCollectionsPlans = branchPartyCollectionsPlans;
     public void addBranchPartyCollectionsPlan(BranchPartyCollectionsPlan branchPartyCollectionsPlan) {
        this.branchPartyCollectionsPlans.add(branchPartyCollectionsPlan);
        if (branchPartyCollectionsPlan.getOperationDayWorkingCapitalPlan() == null || branchPartyCollectionsPlan.getOperationDayWorkingCapitalPlan() != this) {       
             branchPartyCollectionsPlan.setOperationDayWorkingCapitalPlan(this);
     public void removeBranchPartyCollectionsPlan(BranchPartyCollectionsPlan branchPartyCollectionsPlan) {
          if (branchPartyCollectionsPlan == null)
               return;
          if (this.branchPartyCollectionsPlans != null)
               if (this.branchPartyCollectionsPlans.remove(branchPartyCollectionsPlan)) {
                    branchPartyCollectionsPlan.setOperationDayWorkingCapitalPlan((OperationDayWorkingCapitalPlan)null);
and Second one is : BranchPartyCollectionsPlan in which the following relation(inverse) is defined:
@ManyToOne(fetch=FetchType.EAGER)
     @JoinColumn(name="OPERATIONDAYWORKINGCAPITALPLANID")
     OperationDayWorkingCapitalPlan operationDayWorkingCapitalPlan
  related getter and setter:
     public OperationDayWorkingCapitalPlan getOperationDayWorkingCapitalPlan() {
          return operationDayWorkingCapitalPlan;
     public void setOperationDayWorkingCapitalPlan(
               OperationDayWorkingCapitalPlan operationDayWorkingCapitalPlan) {
          OperationDayWorkingCapitalPlan oldOperationDayWorkingCapitalPlan = this.operationDayWorkingCapitalPlan;
          if (oldOperationDayWorkingCapitalPlan != null){
               oldOperationDayWorkingCapitalPlan.removeBranchPartyCollectionsPlan(this);
          this.operationDayWorkingCapitalPlan = operationDayWorkingCapitalPlan;
          if (operationDayWorkingCapitalPlan != null){
               operationDayWorkingCapitalPlan.addBranchPartyCollectionsPlan(this);
Plz help me where am I wrong. Why objects(BranchPartyCollectionsPlan) from collection not delete when I merge the main object (OperationDayWorkingCapitalPlan).
