Set the value to primary key

Question

Hi.,
I am using jdev 11.1.1.5
I had created GlHdEo and GLLnEO with corresponding VO . I had created a viewlink
GlHd.jrnlno = GlLn.jrnlNo and
GlHd.jrnltype = GlLn.jrnltype and
GlHd.jrnlSfx = GlLn.jrnlSfx
In UI I dragged and dropped GlHd as adf:forms and GlLn as adf:table.
GlHd.jrno as OutputText with label
I had dragged and dropped [save] button
    public void cb7_actionListener(ActionEvent actionEvent) {
        // Add event code here...
        BindingContainer bindings1 = getBindings();
        DCIteratorBinding dciter1 = (DCIteratorBinding) bindings1.get("GlJrnlHdView2Iterator");
        Row glhdr = dciter1.getCurrentRow();
        glhdr.setAttribute("GlJrnlNo",getit59Value());
        DCIteratorBinding dciter = (DCIteratorBinding) bindings1.get ("GlmYearlyDocNosView1Iterator");
        Integer value = Integer.valueOf(dciter.getCurrentRow().getAttribute("GydnDocNextNo").toString())+1;
        dciter.getCurrentRow().setAttribute("GydnDocNextNo",value);
        dciter.getDataControl().commitTransaction();
        OperationBinding ob = bindings1.getOperationBinding("Commit");
        Object result = ob.execute();
    public String getit59Value(){
        DCBindingContainer dcbindings = (DCBindingContainer)getBindings();
        DCIteratorBinding dciterator = dcbindings.findIteratorBinding("GlmYearlyDocNosView1Iterator");
        Row row= dciterator.getCurrentRow();
        return (String)row.getAttribute("GydnDocNextNo");
    }I am getting error as jrnlNo should be entered JrnlNO is a primary key

Answer 1

My logic is explained below
public void cb7_actionListener(ActionEvent actionEvent) {
        //In the following code i would set the value of GlHd.GlJrnlNo - Primary Key
        BindingContainer bindings1 = getBindings();
        DCIteratorBinding dciter1 = (DCIteratorBinding) bindings1.get("GlJrnlHdView2Iterator");
        Row glhdr = dciter1.getCurrentRow();
        glhdr.setAttribute("GlJrnlNo",getit59Value());
        // In the following code i would increment the value of gydn.GydnDocNextNo  
        DCIteratorBinding dciter = (DCIteratorBinding) bindings1.get ("GlmYearlyDocNosView1Iterator");
        Integer value = Integer.valueOf(dciter.getCurrentRow().getAttribute("GydnDocNextNo").toString())+1;
        dciter.getCurrentRow().setAttribute("GydnDocNextNo",value);
        dciter.getDataControl().commitTransaction(); //This commit is used to affect the changes in gydn
        OperationBinding ob = bindings1.getOperationBinding("Commit"); //This commit is used for entire table that had been used in UI
        Object result = ob.execute();
//This method is used to retrun the value of GydnDocNextNo
    public String getit59Value(){
        DCBindingContainer dcbindings = (DCBindingContainer)getBindings();
        DCIteratorBinding dciterator = dcbindings.findIteratorBinding("GlmYearlyDocNosView1Iterator");
        Row row= dciterator.getCurrentRow();
        return (String)row.getAttribute("GydnDocNextNo");
    }In this i am performing following operation
=>I am set the value of gydn.GydnDocNextNo to GlHd.GlJrnlNo
=>I am incrementing the value for gydn.GydnDocNextNo
