Binding ADF UI components to managed beans instead of using bindings

Hi All,
We are working on a ADF based development project and we have complex data input forms.
We have close to 200 input forms for different products and each form has different details.
Requirement is to store the data captured in the input forms as XML in database instead of storing the information in relational tables to avoid creating tables for each of the 200 products.
We are planning to capture user input in page flow scoped managed beans and when user save the data, generate the XML from managed bean data and store the XML string in DB using ADF BC.
So we would develop the UI more like a normal J2ee application using JSF where managed beans are used to collect data, and then use ADF BC for database persistence.
Is it a good practice to bind the managed beans to UI bypassing the bindings? (We can't use bindings as we store data in XML format).

Hi Alex,
That is not the right way to get the component, #{it1} is not valid.
Here is the sample code to get the component by id, but is not recommended as you should know the parent component ids as well and it would be difficult to maintain in long run:
FacesContext context = FacesContext.getCurrentInstance();
context.getViewRoot().findComponent("<id>")What is your exact usecase?
Any specific reason for not using binding property?

ADF Faces: How to get the ADF BindingContainer in a managed bean?

I not sure how to get the BindingContainer instance from inside of a managed bean method. I have tried the following config, but it does not work in all situations.
<managed-bean>

      <value>#{bindings}</value>
    </managed-property>
    
</managed-bean>When an ActionListener- method of my ShowBooks bean is called the property bindingContainer is NULL!!
Is there a save way to get the BindingContainer in my bean??
Any hints are welcome.

Howto: Iterate ADF BC from a managed bean from the View?

Hi Everyone,
I've been trying to iterate a BC ADF object from a managed bean from the view layer. Here is what I have done so far, but I don't seem to get any records:
In faces-config.xml, I am passing in the BindingContext to the managed bean. (This is a session scoped bean).
<managed-property>
      <property-name>bindings</property-name>
      <property-class>oracle.adf.model.BindingContext</property-class>
      <value>#{data}</value>
    </managed-property>In the testPageDef.xml I have the executables and bindings setup:
<executables>
    <iterator id="TestRO1Iterator" RangeSize="-1" Binds="TestRO1"
              DataControl="ApplicationControlDataControl"/>
</executables>
<bindings>
    <table id="TestRO1" IterBinding="TestRO1Iterator">
      <AttrNames>
        <Item Value="C1"/>
        <Item Value="C2"/>
      </AttrNames>
    </table>
</bindings>In my managed bean, in addition to the accessors for the bindingContext of bindings, I have:
             BindingContainer bc = getBindings().findBindingContainer("testPageDef");
             ControlBinding cb = bc.getControlBinding("TestRO1");
             RangeBinding rb = (RangeBinding)cb;
             List testList = rb.getRangeSet();
             Iterator testIter = testList.iterator();
             int testCount = testList.size();
             while (testIter.hasNext()) {
               Map attrs = (Map)testIter.next();
               System.out.println(attrs.get("C1")+","+attrs.get("C2"));
               //Do some fancy stuff here with the values.
             }However, my testList.size() always returns 0.
Is this the right method to programatically access the data from the view layer from a managed bean, or have I missed something completely? Are there any working samples that I could take a look at?

ADF Show popup from managed bean

Hi, i have one popup in jspx. On click of a command button a method in managed bean should be called and that has to decide whether to show the popup or not. I have a check and using that i need to show this popup. How to show/invoke the popup from managed bean? I used script also but it was not working. Kindly help me.
Thank you,

Hi,
Which JDeveloper Release You Use?
In JDeveloper11g the structure View---->Document----->Form.
Try one of these solutions:
- Try to put it outside of your pageTemplate tage as:
<af:view>
<af:popup>
</af:popup>
<af:pageTemplate>
<f:facet>
<af:decorativeBox>
<af:view>
I don't know is it possible or not.
- you can put the ids of your popup container as
StringBuilder strb =
new StringBuilder("AdfPage.PAGE.findComponent(\"container1:container2:popup5\").show();");

Hi,
a bind variable in a VO needs to be exposed as an executeWithParams operation in the pageDef file. Just add a new action binding to the pageDef file (context menu) and select the executeWithParams operation on teh VO. Then in the argument field, reference the managed bean property for the value

I want to get a adf component in managed bean with jsff. What can I do?

I want to get a adf component using FacesContext.getCurrentInstance().getViewRoot().findComponent("my component id").

The error is "can not find view root".

What features do you need in the discussion board and how big do you forecast the community to be?
I gather that you really want a free solution.
No software is perfect but when you pay for software you generally get features and the expectation of a certain minimum level of support.
With open source, you get free, features and some support but you also get constant security fixes, regular update patches, plus lots of trawling through online forums looking for tweaks and workarounds. Expect to invest lots of time maintaining it.
I've used phpBB in the past but never had issues with DW touching the coding. It served its purpose for me and the community at the time but the issues I dealt with regularly were the constant updates/bugfixes and never ending spam, spam, spam.

Using Managed bean

Hi All,
How to use managed bean instead of backing bean to retreive a value from a object.
a)Say in my form i have selectoneChoice box and i need to retreive the value inputed by the user
b)According to the value selected by the user i need to show a tick mark or cross mark. Is it possible.
Am using ADF 11g
Please guide me how to acheive this.
Thanks in Advance

Your backing bean can access the bindings object and get the value of the attribute from there in your code.
Lots of code samples for this here:
http://biemond.blogspot.com/2009/03/some-handy-code-for-backing-beans-adf.html
For list binding there is a little trick though:
http://www.oracle.com/technetwork/developer-tools/jdev/listbindingvalue-088449.html
I would also suggest that you watch the seminars about binding in the ADF Insider series:

JSF - Best Practice For Using Managed Bean

I want to discuss what is the best practice for managed bean usage, especially using session scope or request scope to build database driven pages
---- Session Bean ----
- In the book Core Java Server Faces, the author mentioned that most of the cases session bean should be used, unless the processing is passed on to other handler. Since JSF can store the state on client side, i think storing everything in session is not a big memory concern. (can some expert confirm this is true?) Session objects are easy to manage and states can be shared across the pages. It can make programming easy.
In the case of a page binded to a resultset, the bean usually helds a java.util.List object for the result, which is intialized in the constructor by query the database first. However, this approach has a problem: when user navigates to other page and comes back, the data is not refreshed. You can of course solve the problem by issuing query everytime in your getXXX method. But you need to be very careful that you don't bind this XXX property too many times. In the case of querying in getXXX, setXXX is also tricky as you don't have a member to set. You usually don't want to persist the resultset changes in the setXXX as the changes may not be final, in stead, you want to handle in the actionlistener (like a save(actionevent)).
I would glad to see your thought on this.
--- Request Bean ---
request bean is initialized everytime a reuqest is made. It sometimes drove me nuts because JSF seems not to be every consistent in updating model values. Suppose you have a page showing parent-children a list of records from database, and you also allow user to change directly on the children. if I hbind the parent to a bean called #{Parent} and you bind the children to ADF table (value="#{Parent.children}" var="rowValue". If I set Parent as a request scope, the setChildren method is never called when I submit the form. Not sure if this is just for ADF or it is JSF problem. But if you change the bean to session scope, everything works fine.
I believe JSF doesn't update the bindings for all component attributes. It only update the input component value binding. Some one please verify this is true.
In many cases, i found request bean is very hard to work with if there are lots of updates. (I have lots of trouble with update the binding value for rendered attributes).
However, request bean is working fine for read only pages and simple binded forms. It definitely frees up memory quicker than session bean.
----- any comments or opinions are welcome!!! ------

I think it should be either Option 2 or Option 3.
Option 2 would be necessary if the bean data depends on some request parameters.
(Example: Getting customer bean for a particular customer id)
Otherwise Option 3 seems the reasonable approach.
But, I am also pondering on this issue. The above are just my initial thoughts.

Sharing managed beans

Ok �. This is driving me nuts. I�m relatively new to JSF (2 week profession  ), and I may not have grasped the concept of Managed Beans. The problem is detailed below:
Development Environment:
WebSphere Studio 1.5.2 � This creates a backing bean for each respective JSP page that is created, including setters and getters for each managed bean. The two backing beans I�ll talk about whilst specifying the problem are stored in session scope.
The Problem:
I can�t share data between two pages. On the first page I create managed bean in session scope and make this reusable (let�s say person). On the second page I add the reusable Person bean. The resulting entry in the faces.config file is:
<managed-bean>
<managed-bean-name>person</managed-bean-name>
<managed-bean-class>ibm.wlrs.model.PersonVO</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
Both pages however maintain an independent copy of the managed bean instead of JSF maintaining a shared one. I�ve looked at several documents, and too me it seems as though this bean should be shared between the two pages�� HELP!
On the first page I create a new Person object with the relevant details. This person is created upon a button click added to the backing beans managed bean.
//Page 1 add person from button click
public String doLnkInsertEntryAction() {
System.out.println("Insert");
     Person p1 = new Person();
     p1.setName("Duncan");
     setPerson(p1);
System.out.println(getPerson().getName());
//This prints the person�s name
     return "insert";
I have also setup a page load event to test that the person object stays in the session
//Page 1 page load
public void onPageLoadBegin(FacesContext facescontext) {
     System.out.println(getPerson().getName());
//Prints the person name that was added during the button click event� on Postback or even after going from page1 � page2 and back again.
On Page two if I try and access the managedBean contained within the session, the �name� will always print out as null.
//Page 2 page load
public void onPageLoadBegin(FacesContext facescontext) {
     System.out.println(getPerson().getName());
If I add an any information to the managed bean on page two i.e. person.setName(�Another�), this data stays in the session, only for page two though.
Is this how JSF is supposed to work? I though if a managed bean was stored in the session, the object (and it�s data) should be reusable between pages.
Sorry for the long post�. I though it would be worth while to try and be as specific as possible.
Thanks
Duncan

And� I still don�t understand why two independent
copies are kept by the pages�Because YOU create the copy.
JSF (exactly speaking the default VariableResolver) at first searches for an attribute in
request scope, then session scope, then application scope with the matching name.
Only when no attribute is found, it examines faces-config.xml, creates an instance of
the specified class, and stores the instance in the specified scope.
It never creates two instances with a same name.
I.E� On Page 1�. Several Person objects are stored in
a DataTable. The Vector containing the Person objects
is a managed bean bound to this data table. Upon a
button click I require to extract a person from the
data table and place it into the managed bean session
scope for person. Humm, I guess you misunderstand what the managed bean is.
h:dataTable has the "var" attribute which is used to refer each Person object.
JSF implements the "var" variable as a request scope attribute and re-binds it
to each Person object in the iteration. So, it is not a managed bean but is simply an attribute.
The entry of faces-config.xml is not required.
To know how to pass the selected row data to the next page, please see some
example using h:dataTable and javax.faces.model.DataModel.

Pageless Managed beans and operation bindings, design question

Hi,
I am using ADF Faces and ADF BC and JDev 10.1.3.
I want to declaratively execute an operation binding from a managed bean which does not have a page definition.
How can I create a page definition for a managed bean which will allow me to define and call operation bindings in the same way that you can in a backing bean?
In the past I have used the binding layer to get references to the AM and then execute the client methods directly.
How can I do this declaratively from a managed bean?
regards,
Brenden

Hi Steve,
a good example would be a managed bean which is used by many pages for provide dynamic page forwarding (using global forwards).
The page forwarding is based on what data the user has selected and the entry tasklist will have pages added and removed based on the users entered information.
At the moment I use references in the managed bean which get the binding context by evaluating #{data} to get a reference to the AM and directly call an client method, which calls a PL/SQL procedure and returns a global forward string. The AM is imported into the managed bean and methods called directly.
This is just one example, but probably the best I can come up with for now.
In a backing bean I can use an operation binding to call a method and get a result declaratively like this:
        BindingContainer bindings = getBindings();
        OperationBinding operation = bindings.getOperationBinding("getUserByEmail");
        operation.getParamsMap().put("email", email);
        String userName = (String)operation.execute();whereas in a managed bean I have to get direct references to the AM to call the method directly.
if there is a way to do this in the same way as backing beans it would seem a more abstracted and cleaner approach?
regards,
Brenden

How to add property through managed-beans.xml

Hi,
I am trying to take a hard coded value property from managed-beans.xml file. I tried using :
<managed-property>
<property-name> filename </property-name>
<value> xx </value>
I called getProperty("filename"); from one of my bean classes and it did not recognise it.
I am not sure how to do this one. any help will be appreciated.
Thanks

I'm not sure what getProperty method you are referring to in your original posting. Is this a method on your managed bean class?
Managed beans are implemented as regular JavaBeans so you will need to add a setFilename(String) and getFilename() method to your backing bean class to get this to work correctly. The setter method will get called automatically when the bean is first instantiated, either by accessing it from a JSP value-binding expression as a result of calling context.getApplication().getVariableResolver().resolve(context, beanName) where context is an instance of FacesContext and beanName the name of the managed bean as specified in faces-config.xml. You can then use the getter method to access the property value from within your application code.
Alternatively, if you don't want to implement a JavaBean class, you can specify java.lang.HashMap as the managed bean class and use myBean.get("filename") to access the property instead.
Hope this helps.

Get component Id in managed bean

Hi experts,
I am going to ask a foolish question, but since i'm a newbie i hope you'll forgive me .
I am using JDev version: 11.1.2.3.0. My question is: Is it possible to get a component id inside a managed bean? By components i mean, buttons or menu items. The scenario i would like to create is this:
I am using JasperReports to generate some required reports. I would like to do something like having a Menu with different items. By clicking each one of them, set a string in the managed bean i'm using to generate the reports (actually the string would be the name of the jrxml file i am going to load). And this string would get it's value based on which menu item is selected.
Is it possible to do such a thing? Or may be some other way would be more suitable?
Thank you in advance!

MenuRenderer is a class that renders the current value of
UISelectOne or UISelectMany component as a list of
menu options and makes use of getId.
