Removing Automatic Backing Bean Updates in Jdev 11.1.2.2.0

Hi,
in the User Guide and in the book "Jdeveloper 11g Handbook" I'm reading:
Remove Automatic Backing Bean Updates
1. Click page.jspx file tab. Click the Design tab
2. Select Design | Page Properties and click the Component Binding tab. Unselect Auto Bind.
Why I cannot locate Page Properties and the Component Bind tab?
Where is? Can help me with some print screen?

Hi,
Actually first chance to switch it off is when you create a new page: There is a managed bean tab in which you can do this. For existing pages, open the page in the visual editor and choose Design --> Page Properties from teh JDeveloper menu. In the opened dialog there is a "Component Binding" tab you press

Turning off automatic backing bean code generation

Hi,
When I created my JSP page using the wizard I selected to automatically expose UI components in a new managed bean. Is there any way I can now turn this off so that I can just enter the backing code that I want.
Thanks,
Dave

Hi Grant,
Sorry I don't think I explained my problem very well.
I've already created the JSP page and don't really want to create the whole thing again with the flag not set. I can remove any code that is already added that I don't want but I was wondering if there is a property I can change so it will no longer automatically add backing bean code whenever I add any new controls to the page.
Thanks for your help,
Dave

Remove unwanted backing bean binding

Hi All,
My JSFX page has around 200 fields and I have to manipulate only a few fields in the backing bean. When I use this method to bind the UI components with the backing bean Design--> Page Properties ---> Component Binding ---> Auto Bind, all the page UI components get bound. This creates unnecssary binding and my backing bean java files becomes quite messy and runs into 5000 lines. Is it possible to remove the unwanted ones manually without causing any harm. What's the best practice by the way.
Thanks

Hi,

This exactly is why the auto-generate option for backing beans is disabled by default in JDeveloper. There is no functionality in the IDE to remove unneeded bindings (how would the tool be able to tell what you need and what you don't need given that managed beans can be referenced from other managed beans and are referenced from EL in the component binding property).
Best practices for working with backing beans is to not create them by default and instead use managed bean that you turn into backing beans (which is when they have a page component binding reference) only when needed. This way you stay in control
Sorry, I have no better answer for this

How-to remove a jsf backing bean from session?

How can I find the reference to a backing bean (with session scope) and then remove the bean?
I may have painted myself into a corner. When most of my pages are navigated to, they get key info from session and then initially populate the page fields. I populate the fields in the constructor with values from the database based on the keys found in session. So the second time a particular page is called the values may be stale or completely unrelated to the page navigated from because the bean already exists and, naturally, the constructor is never called.
I'm thinking if I could remove the backing bean, jsf wouldn't find it so it would be recreated on subsequent navigations. Since the constructor would be called with every navigation to the page, the values would not be stale or unrelated.
Any help would be greatly appreciated.
TIA,
Al Malin

//To reset session bean
FacesContext
     .getCurrentInstance()
     .getApplication()
     .createValueBinding( "#{yourBeanName}").setValue(FacesContext.getCurrentInstance(), null );
//To get session bean reference
Object obj = FacesContext
          .getCurrentInstance()
          .getApplication()
          .createValueBinding("#{yourBeanName}")
          .getValue(FacesContext.getCurrentInstance());
YourSessionBean bean = (YourSessionBean)obj;

How to get selected items from a tree in backing bean without adfbc

Hi ADF Experts,
Below is my code for af:tree. My question is how can I get selected Items from the selectionListener (without adf bc) this uses formation of tree from backing bean.
Using Jdev 11.1.1.7.0
<af:tree var="node" value="#{pageFlowScope.MerchandizeBean.model}"
                  binding="#{pageFlowScope.MerchandizeBean.treeModel}"     id="tree" immediate="true" autoHeightRows="0"
                       styleClass="AFStretchWidth" rowSelection="multiple"
                       selectionListener="#{pageFlowScope.MerchandizeBean.treeNodeSelection}">
                <f:facet name="nodeStamp">
                  <af:commandLink text="#{node.classDescription}"
                       actionListener="#{pageFlowScope.MerchandizeBean.createListManyItemForMerchandise}"           id="displayTable" partialSubmit="true">
                  </af:commandLink>
                </f:facet>
              </af:tree>
    public void treeNodeSelection(SelectionEvent selectionEvent) {
        // Add event code here...
        RichTree tree = (RichTree)selectionEvent.getSource();
                TreeModel model = (TreeModel)tree.getValue();
                //get selected value
Thanks

Hi,
in a multi select case, try
RowKeySet rks = tree.getSelectedRowKeys();
Iterator iter = rks.iterator();
while(iterator.hasNext()){
Object aKey = iterator.next();
tree. setRowKey(aKey);
Object rowData ? tree.getRowData();

Backing Bean

Current release jdeveloper adf
I want to pass 2 column values from a table in formA and assign the passed values to 2 columns in a table in formB
In FormA the values are WoOrderNo and WoTaskNo
In FormB the columns are Wo_no and Task_no (these columns are hidden)
Is my only option to use a backing bean?
If so, then they way I would like to pass the 2 values using a 2 setPropertyListeners in formA using pageFlowScope.
Have a backing bean update columns in FormB.
I cann't find any doc's on how to do this.
What is the best practice on how to accomplish my requirement.

How to update row in backing bean?

Hallo,
i want to do the following things ina backing bean of Jdev 10.1.3.3:
- positioning to a special row, it has an Id
- change the value of an attribute
- update the row
never before i have done that. any help is appreciated.

Hi,
If you're using ADF/BC you need to find the iterator to the view object that you want to update.
To get the iterator you must first get your data bindings. This is how I get the binding container
Map myMap = FacesContext.getCurrentInstance().getExternalContext().getRequestMap();
DCBindingContainer dcbc = (DCBindingContainer)myMap.get("bindings");You can get the iterator using this:
dcbc.findIteratorBinding("nameOfIterator");You can then set the current row with setCurrentRowWithKeyValue("someKey"), get the current row with getCurrentRow(), change an attribute on the Row with setAttribute(int,String) and you're all set.
Hope this works for you,
Mark

H:inputText and immediate="true" not updating cached backing bean value

Hi,
I am having a problem with h:inputText and immediate="true" when
returning back to the same page.I looked through the forums but the
only solution to remove the page from the session works only if I
don't have to change any button label names in the page I am going back
to.Unfortunately, I have to change a button name when I go back to the
same page.The button name change works if i don't remove the page from
session but then h:inputtext has stale values in it from the backing
bean.I also need to avoid validation as it is a huge form.
I have tried looking through the JSF forums but they didn't have any
answers for a very similar question.
I am not sure how exactly to use component binding for the input text and update the model values using an actionListener.I have tried puting a binding on an input text field and then used an actionListener instead of immediate="true' in the h:commandLink.But, putting context.renderResponse() in the actionListener method results in the model values not getting updated.
I have also tried using component.processUpdates(facesContext) as in the UpdateModelValuePhase class -that too doesn't work.
Thanks for any help,
Vijay
Details:
The <h:inputText ..> does not populate the values back from a backing
bean when immediate="true" is used when an action is called.
<h:commandLink id="selectPrincipalId"
action="#{application.selectPrincipal}" immediate="true">
Only <h:inputText has the cached values from the first entry.
<h:inputText id="principalLastName1Id"
value="#{application.currentPrincipal.lastName}" size="10"/><== this
has the cached value from the backing bean application.
<h:outputText gets the new values from the backing bean when the same
page is reentered.
<h:outputText value="#{application.currentPrincipal.lastName}"></h:outputText><==
this refreshes with the new value from the backing bean application.
Here is the solution to rectify the problem:
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
Map sessionMap = externalContext.getSessionMap();
sessionMap.remove("/jsp/befg/tc/apply/enterCreditApplication.jsp");
<== this is the name of the jsf page as defined in the
faces-config.xml.

Hi,I have encountered the same problem as you,and I find a solution myself,which is shown as follows,but I don't know if these is any hidden trouble in the code.
<h:form>
<h:commandLink action="#{app.action}" immediate="true" actionListener="#{app.update}">xxxx</h:commandLink>
<h:inputText id="_id" value="#{app.val}" immediate="true"/> //must set immediate="true" else the model will be not updated
<h:message for="_id"/>
</h:form>
public class App{
public void update(ActionEvent event){
     FacesContext c = FacesContext.getCurrentInstance();
     UIViewRoot root =c.getViewRoot();
     root.processUpdates(c);//to update model and short-circuit the validators
in such circumstance,the UIViewRoot's processUpdates method will be called in the actionlistener,and the back bean who titled to immediate(true)'s inputText will be updated, but the one who titled to immdiate(false)'s inputText will not be updated,Why?
Can anyone tell me way?and how to solve?
Thanks a lot!

Need to Add and Remove Columns of ADF Read Only table from Backing bean

I have a scenario where I am trying to Populate TransientVO which is shown has a ADF Read Only Table in page.
I have couple of Check Boxes Based on their selection I am trying to render and hide certain Columns.
But the Issue which I am facing is only the Column Header seems to change where as the Rows and Values doesnt..
even If I apply the expression language rendering condition on the outputText inside those columns.. ..
So I am thinking to add and remove VO Attribute columns to the table from backing bean.
Need some sample code snippet or a better design to achieve this. Its kind of urgent too...having an aggressive deadline :(
Please chip in People..
Thanks in Advance .

Backing bean properties not getting updated

I have an input text in my JSP page and it is component-bound to backing bean. The problem is that when I change value of the InputText in the JSP, the value is not getting updated in the backing bean.
Here is the InputField definition in JSP page.
<h:inputText binding="#{backing_employeeEdit.firstName}"
id="firstName"/>
and here is the setter in backing bean
public void setFirstName(HtmlInputText inputText1) {
this.firstName = inputText1;
Pls note that there is no validation errors because the page navigates successfully. The only problem is that new value is not updated.

I don't know, wht exactly u wants to do... Here is java code and is working fine for me...
Emp.java
public void action() {
     System.out.println(inputText.getValue());
     Emp tt = new Emp();
     inputText.setValue(inputText.getValue().toString()+"bilal");
     tt.setInputText(inputText);
     System.out.println(inputText.getValue());
JSP...
<f:view>
<h:form>
<h:inputText binding="#{emp.inputText}" />
<h:commandButton value="submit" action="#{emp.action}" />
</h:form>
</f:view>
faces-config file contents....
<managed-bean>
          <managed-bean-name>emp</managed-bean-name>
          <managed-bean-class>
               com.nous.application.Emp
          </managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
Here scope has to be session, otherwise u will lose old value...

Refresh af:selectOneChoice in backed bean (JDev 10.1.3.5)

I have jspx with af:selectOneChoice named Status. When user changes value of selectOneChoice from IN_WORK to COMPLETED, I check business rules.
If some rules are violated, I show error messages and I want to set value of af:selectOneChoice back to IN_WORK.
But with my code this doesn't occur - value of selectOneChoice stay with value COMPLETED :
Here is definition of selectOneChoice. I set id="Status" and partialTriggers="Status" for PPR to work:
<af:selectOneChoice value="#{bindings.HgpPorocilaView1Status.inputValue}"
label="Status"
valueChangeListener="#{UrejanjePorocilaBacked.onValueChangeStatus}"
autoSubmit="true" id="Status"
partialTriggers="Status" immediate="true"
valuePassThru="false">
<f:selectItems value="#{bindings.HgpPorocilaView1Status.items}"/>
Here is UrejanjePorocilaBacked.onValueChangeStatus:
public void onValueChangeStatus(ValueChangeEvent valueChangeEvent) {
// Add event code here...
DCBindingContainer dcBindings = (DCBindingContainer)getBindings();
DCIteratorBinding iter = dcBindings.findIteratorBinding("HgpPorocilaView1Iterator");
Row row = iter.getCurrentRow();
//If new value of Status is COMPLETED
if (row.getAttribute("Status") == "COMPLETED" {
//Check rules
if (row.getAttribute("OneField").toString() == "WRONGVALUE")
//If rules are violated, display error message
FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_ERROR, "Business rules violation!", "Rule1 message, Rule2 message, ... ");
FacesContext.getCurrentInstance().addMessage(null, message); // Null for global message
//Set Status af:selectOneChoice back to IN_WORK
row.setAttribute("Status","IN_WORK");
So - the problem is that Status doesn't change back to IN_WORK. I have similar principle for af:inputText in same backed bean and it works OK.
I have Jdev 10.1.3.5
Please some suggestions, what is wrong.
Regards,
Sašo

Hi,
The ValueChange Listener will not stop it from setting the submited value in the viewRow.
You should try a different approach of the matter.
You should use a validation method in you entity. Or perhaps place custom code in the setter of the attribute in you ViewRowImpl.
Regards,
Dimitris.

I have a iMac desktop and a macbook pro laptop I work mainly on the desktop but when i go away for work I take my laptop. Is there any way to make it automatically back up to mirror my desktop? Like when I update a file it updates on there too, if I install software it installs on there too etc?
When I first got the laptop I syned it to load with all the same software etc but it hasn't continued to sync
Thanks

I use
Chronosync (http://www.econtechnologies.com/pages/cs/chrono_overview.html)

Automatic amendment of jsf when backing beans refactored: tool support ?

Hi there,
Whenever I refactor backing beans I have to adjust EL expressions in all my jsf files manually.
That is annoying, time-consuming and finally prevents me from refactoring regularly.
Does anybody know an IDE or tool that supports refactoring of backing beans ?
Many thanks in advance

Using a backing bean in JDeveloper to assign bean class variables

I am using JDeveloper 10 to make a jsp page that is a form full of inputs and buttons. JDeveloper then creates the setters and getters for you for the ids of the various inputs and buttons. I also have used JDeveloper to create a backing bean.
The idea of this is to have the backing bean read in parameter(s) from an http source/link(when the form is loaded or instantiated) and assign those parameter(s) to one of the bean class local variables.
The reason i want to do this is, is that when the form is loaded the first thing it will do is open up an available database(in the bean class constructor), then in the constructor call a function to do a database query that will return a result set that will then be used to fill up the form.
That variable that is assigned by the backing bean will be the value of a unique database identifier for doing the sql query so that is why it is important that i get this value as the form loads.
So simply i need to find out from someone how to do this. i am totally new to doing any jsp development or using managed beans and i have gotten far enough to launch the form, retrieve and write to the database using sql queries and all the rest.
I just dont know enough about managed beans to make a decision on things like making the bean have a session scope. do i need request scope? if i change to request scope how do i make sure the database isn't being called every time the page changes or is refreshed?(when i had it as request scope the constructor was being called every time the page was reloaded and that isnt effecient at all, especially with multiple users). can you define more than one managed bean in one faces config file? do i have to manually change something in the jsp file to make sure things run smoothly?
Just maybe things are easier than i see them to be and my only problem is that i just dont understand what i am doing. here is what my backing bean looks like now with just basic session scope.
An example of course would be something like: http://host:port/context-root/faces/register.jsp?12345 - where 12345 would be the value that i would like to assign to a local variable in my bean class that can then be used for filtering out information via a query then filling up the form, all this happening at instantiation.

This is what i have now, i've tried tons of stuff on the web like assigned value parameters but just am stuck on exactly what to do as nothing has seemed to work. Any help would be appreciated. Thanks in advance!

Hi,
don't think you will get a readily programmed solution to this (though I wish you luck). Here's how I would approach the managed bean issue
- One managed bean that you configure from a java.util.HashMap. This bean should be in requestScope (should be okay here). Say the bean is called "formFields", then adding data to it can be done with the following EL #{formBean['attribute_name']}. You need to add this as the value Expression of the inputText field you create dynamically. The filed will then read and write to the HashMap
- Create a managed bean in session scope to handle the database interaction. Put this into session scope (e.g. "database")
- Create a managed bean that holds the action listener that handles the update, insert and delete actions (e.g. logic handler). This bean has a JSF reference to the root component in the page (or the form layout component to add the fields to)
The "database" bean is referenced from the logic handler managed bean using the #{database} expression, which you resolve using a ValueBinding (ExpressionBinding in JSF 1.2). Or, you configure the bean as a managed property.
The logic managed bean also needs to reference the formFields bean (similar to above) to access the contained filed names and attributes. If the filed attributes match column names in the database then you should be all set
