DialogListener vs Attribute Binding - Which fires first?

Question

Hi All,
I'm using Jdeveloper 11.1.1.2.0. I'm about 3 weeks into learning this program, and could definitely be considered new to database work on this level. This is my first post. This particular problem has got me befuddled even moreso than usual. Yes, google has finally failed me.
I am attempting to create a recursive tree table based off of this helpful article: [Recursive Editable Tree|http://jobinesh.blogspot.com/2010/05/crud-operations-on-tree-table.html]
However, instead of making the fields editable on the main page, I would like to update the fields (or create new rows) through an af:popup. I accomplish this by having a button call the popup, which has the following structure:
<af:popup id="p1"
popupFetchListener="#{DialogListenerCollection.editPopupFetchListener}"
popupCanceledListener="#{DialogListenerCollection.editPopupCancelListener}">
<af:dialog id="d2"
dialogListener="#{DialogListenerCollection.editDialogListener}" title="BOM Edit">
<af:panelFormLayout id="pfl1" maxColumns="2">
<f:facet name="footer"/>
<af:panelLabelAndMessage label="Parent" id="plam1" for="ot6">
<af:outputText value="Parent Binding" id="ot6"/>
</af:panelLabelAndMessage>
<af:inputText label="Child" id="it1"
binding="#{BomCRUD.bomEditChild}"/>
<af:inputText label="Qty" id="inputText1"
binding="#{BomCRUD.bomEditQty}">
<af:convertNumber type="number" integerOnly="true"/>
</af:inputText>
</af:panelFormLayout>
</af:dialog>
</af:popup>
As you can see, the last inputText has a binding of BomCRUD.bomEditQty and is set to convert to a number of type integer. The binding has code as follows (abbreviated for space):
public class BomCRUD
private RichInputText bomEditQty;
public void setBomEditQty(RichInputText bomEditQty)
this.bomEditQty = bomEditQty;
public RichInputText getBomEditQty()
return bomEditQty;
When I enter in the values for the Child and Qty af:inputText items and press the "OK" button on the dialog, I receive the following conversion error:
Cannot create an object of type:java.lang.Number from type:oracle.adf.view.rich.component.rich.input.RichInputText with value:RichInputText[UIXEditableFacesBeanImpl, id=inputText1]
The RichInputText is not converting to a number. Why? That's a puzzle I just can't figure out. I thought logically: the next thing I should do is change BomEditQty from RichInputText to a Number type in my BomCrud class. The browser simply goes blank when I attempt that and I receive the following error:
java.lang.IllegalArgumentException: Cannot convert RichInputText[UIXEditableFacesBeanImpl, id=null] of type class oracle.adf.view.rich.component.rich.input.RichInputText to class java.lang.Number
So the next thing I thought was that my editDialogListener is firing BEFORE my BomCRUD.bomEditQty inputText binding has a chance to update, so I should modify my editDialogListener to update the binding before the "createChildren" operation call, but I do not know how to grab what was in the Qty (inputText1) field and put it in the editBomQty field.
At any rate, here is the editDialogListener:
public void editDialogListener(DialogEvent dialogEvent)
if (dialogEvent.getOutcome().name().equals("ok"))
// Put update BomCrud.setEditQty( inputText1's value ) here? How?
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("createChildren");
operationBinding.execute();
The "createChildren" operation binding is located in the AppModuleImpl class, accepting a Number type for the Qty. This method creates a row and inserts the values into the recursive TreeTable at the appropriate row iterator and key.
public void createChildren(RowIterator ri, Key selectedNodeKey, String Child, Number Qty)
That about sums it up. I'm not sure if it's a conversion error, or a problem of DialogListener vs Binding priority. Any help would be appreciated. Thanks in advance guys.

Dimitar, thank you for your response.
If I am trying to insert a new row (not update an existing one), I believe I need to create a Managed Property bomEditChild under the Managed Bean bomCRUD, and then set the binding of the af:InputText to +#{bomCRUD.bomEditChild}+ as seen below:
<af:popup id="p1" ... >
<af:dialog id="d2" dialogListener="#{DialogListenerCollection.editDialogListener}" title="BOM Edit">
<af:inputText label="Child" id="it1" binding="#{BomCRUD.bomEditChild}"/>
</af:popup>
From adfc-config.xml
<managed-bean id="__11">
<managed-bean-name id="__9">BomCRUD</managed-bean-name>
<managed-bean-class id="__12">erp.view.framework.BomCRUD</managed-bean-class>
<managed-bean-scope id="__10">request</managed-bean-scope>
<managed-property id="__2">
<property-name id="__3">bomEditChild</property-name>
<property-class>oracle.adf.view.rich.component.rich.input.RichInputText</property-class>
<value id="__1"></value>
</managed-property>
</managed-bean>
However, when I print the value of the String Child variable of the createChildren class, I get the following:
System.out.println("Child: " + Child); // output command gets me the text below
+Child: RichInputText[UIXEditableFacesBeanImpl, id=it1]+
The createChildren method is detailed below in the pages definition file and implemented in the AppModuleImpl class.
<methodAction id="createChildren" ...>
<NamedData NDName="Child" NDValue="#{BomCRUD.bomEditChild}" NDType="java.lang.String"/>
</methodAction>
It appears the value being passed into my createChildren class is the container ID, not the value entered into the container by the customer. The output is the same whether I declare bomEditChild as a Managed Property under the Managed Bean bomCRUD or not. I am still unsure how to grab the value of the inputted text and/or if the managed property is updating before the createChildren method is being called via the editDialogListener.
Any further ideas?
