Insert Records Based on User requirement

Question

Hi,
I want to Create a set of records based on the user input defined on run time.
According to my present query i am able to create records which is predefined in 'NoOfRows' variable . Hence when i click on this button, by default 2 rows are inserted in my page.
My requirement is to get the 'NoOfRows' from user, hence i added an input text in my Jsf page which gets the value from user and based on that the rows will be inserted. But i coudn't pass my Rich input text value to this variable. i.e 'NoOfRows'. How is this possible to pass my input text value which is defined in my bean to the java class defined in Application Moldule?
This is my code written in AppModuleImpl.java
public void insertDefaultRows(){
ViewObjectImpl Lines = this.getEmpView1();
Lines.executeEmptyRowSet();
int NoOfRows=2;
oracle.jbo.server.ViewRowImpl emptyRow;
for (int i=0; i < noOfRows;i++){
emptyRow = (oracle.jbo.server.ViewRowImpl)Lines.createRow();
emptyRow.setNewRowState(oracle.jbo.Row.STATUS_INITIALIZED);
Lines.insertRow(emptyRow);
This is my backing bean defined for the input text
public void setIt11(RichInputText it11) {
this.it11 = it11;
public RichInputText getIt11() {
return it11;
Hope I'm clear. Any help?

Answer 1

First of all you have to change the signature of the method in the AM to
public void insertDefaultRows(int num){
  if (num <= 0)
    return;
  ViewObjectImpl Lines = this.getEmpView1();
  Lines.executeEmptyRowSet();
  int NoOfRows=num;
  oracle.jbo.server.ViewRowImpl emptyRow;
  for (int i=0; i < noOfRows;i++){
    emptyRow = (oracle.jbo.server.ViewRowImpl)Lines.createRow();
    emptyRow.setNewRowState(oracle.jbo.Row.STATUS_INITIALIZED);
   Lines.insertRow(emptyRow);
}then you expose this method to the client interface of the AM. This makes it available in the data control.
Next you should add a variable in the executable section of the bindings of the page.
1) open the bindings of the page
2) right click on the variables in the executables section and choose 'Insert Inside Variables'->'variable'
3) in the dialog set a name e.g. noOfRows with type java.lang.Integer
4) click the green '+' sign in the Bindings section, select AattributeValues, cklick OK
5) select 'variables' as datasource and 'noOfRows' as attribute
This will create a variable of type integer in the bindings of the page. This can be used to store the value of the inputText component. For this select the inputText in your page and in the property inspector add
#{bindings.noOfRows1.inputValue}to the value property. This will transfer the input from the inputText to the variable you created.
Now open the DataControll and drag the method onto the page and drop it as a button. You then get a dialog where you see the 'num' parameter of the method. In the value field you write the binding you used to store the value from the inputText (#{bindings.noOfRows1.inputValue}).
Last thing to do is to set the autoSubmit property of the inputText to true.
This will pass the value from the inputtext to the method.

Oh, and you can remove the binding of the inputText to the bean as this is not needed!
