ADF Beans

Hi there,
I have a question about ADF beans. While writing an EL expression, what is the difference between writing something like #{beanName.beanProperty} versus #{beanScope.beanName.beanProperty}.
I have created a sample Webcenter portal app. It has a page fragment with 2 inputtext fields. The value for these fields in coming from a bean (have set default values in the constructor). Put the pf in a task flow which in turn is a region on a page.
While setting the values of the fields (via Expression builder), i see the instance of my bean class under 'ADF Managed Beans' as well as 'ADF Managed Beans --> requestScope'. Why is the bean name visible in 2 places?
If the field value is set to #{beanName.beanProperty}, the page runs fine and values get displayed but if field value is set to#{beanScope.beanName.beanProperty} then page fails to load with error:
javax.el.PropertyNotFoundException: Target Unreachable, 'myBean' returned null
Hence the question. Please explain the difference and which is the correct usage.
Thanks in advance.
Bean is registered in taskflow not adfc-config

I f you use one of the traditional JSF memry scopes: [application, session, request] then you need to use #{beanName.beanProperty}.
but if you need to use one of the ADF memory scopes then you need to use #{beanScope.beanName.beanProperty}.
I can't find the document where I read this.

URGENT***How to chance ADF bean properties at runtime?

Hi Friends,
Please help me to get some sample java code to create the ADF UI bean object at runtime.
As per my requirement in my ADF screen (.jspx) I got 3 input text fields, where last fields 2 are disabled while loading the page. When I enter some value in the first textbox and tab out , the second one should be automatically enabled without any button click. Please help me how to achieve the same. How can I set my UI bean properties at runtime (Please share the code to get the UI object)? And how can I able to handle / know where the first text box has value or not.
This is very urgent requirement. Please help me .
Thanks

Hi,
Thanks for helping me. But so far no luck with the 3rd row enabled. Below is my code. As per my real requirement each row should have 2 columns. (col 1: choice box and col2: free textbox).
Can able to make enable the 2nd row's columns. But the last row not getting enabled. Seems the 2nd row textbox (password) value not getting populated in the managed bean. When I print the value it is showing null. (But if I totally remove the first row and enable the 2nd row then test the same. In this case 3rd row getting enabled.). So worried that after enable the 2rd row by EL, it is not passing the entered value to bean it seems.

Hi,
I am using WLS default authentication to protect my JSP pages. Can someone tell
me if it is possible to add more fields to the default login box (in addition
to login and password boxes, I want to ask user the department name). In additional,
can WLS propogate this information (department name) along with other security
credentails to other J2EE components such as EJBs? In my EJBs I want to be able
to get the department name that user provided during login and then use that for
conditional business logic.
Any insights on this subject will be greatly appreciated.
TIA,
-NealYou can't do this with the default simple authentication. That can only handle a
username / password combination.
You should be able to do this with JAAS. You could write a LoginModule that
populates the department as a Principal or public Credential on the Subject in
addition to the normal authentication. You would have to do a callback handler
that passed through the department info to it.
This link has more on WLS's stab at JAAS:
http://e-docs.bea.com/wls/docs61/security/prog.html#1039659
Once you have associated the Subject with the access control context by invoking
a doAs() you should be able to get it back at any point with
Subject.getSubject(AccessController.getContext()) to get access to the
department info.
It will all be a bit of a chore, mind.

I am wondering how open ldap can allow two users with same email.
Any suggestions are welcome.can i try some work around for that?
Thanks.

Hi.
For some reason you have duplicates. Normally is something strange but it can occurs in heavy load / database corruptions or other situations.
You should contact a LDAP Administrator in order to find and fix the duplicate problem.

Gantt chart: Don't know how to use the tooltipkeys and toolkeylabel

I have a problem. Don't know how to use the tooltipkeys and toolkeylabel. I used jquery to select the gantt bars and on mouse over i was getting the task id "tid" then passing it to adf bean with serverlistener and showing a popup that is adf component with javascript. For positioning of the popup I used a button that has width and height 0 and has position absolute and gets the coordinates of the mouse.
"div[et]" is a jquery selector that selects all the elements that have attribute et. I noticed that all the bars have that attribute as a few other attributes as well "part"...

Hi,
To use tooltipkeys and tooltiplabel in gantt, you can add following code in managed bean
public String[] getTooltipKeys()
return new String[]{"columnA", "columnB", "StartDate", "EndDate"};
public String[] getTooltipLabels()
return new String[]{"A", "B", "Start Date", "End Date"};
where , the string array in the ToolTipKeys represents the columns, of the table you have in the gantt component , and the string array in TooltipLabels displays the label you want to display for the table columns.
In the jsff, you could call the bean methods as follows:
tooltipKeys="#{GanttBean.tooltipKeys}"
tooltipKeyLabels="#{GanttBean.tooltipLabels}"

ADF: is it possible to call bean methods from a DataForwardAction?

Hi,
i have created an ADF data control from bean and I have some values bound and populated in a page. As part of the Action class i would like to execute one of the methods in the bean. Is this possible or am i taking the wrong approach?

Yes, there are a few ways of doing it, please see...

Thk in advance.

Hi,
you can create a button with an ActionListener. In the ActionListener you can iterate over the rows (using the iterator) and set the value on the attribute. If you need to save the changes you can call the commit operation binding.

Is there a way to create ADF Table using a bean

Hi,
I am using JDev 11g 11.1.1.2.0.
I am reading an excel sheet and want to generate an ADF table using the same. I already have hold on excel data.
But when I go through the RichTable API, I find that there is no method to add Columns and Rows. Most or all the methods work on the table UI Looks attribute.
Any suggestion? Am I missing a method OR 2 here?
Pls note: The excel (CSV file) using which I am populating my table, will vary for different user. i.e.
say user 1 will upload a CSV file with 7cols and 100 rows while
user 2 will upload the CSV file that has 2 cols and 100 rows.
Hope this makes it clear of my requirements and why I want to populate the table from a bean.
Thanks in advance.

Thanks a lot Joseba, I am now atleast getting column headings. I have questions on the soln given but first here is the code that I use
PS NOTE: on my .jpsx file I have dragged dropped an ADF table, removed its default columns and have bounded it with my bean attrib '_dynaTbl' that is used below.

Here is the problem. I am able to view only column headings but data is not visible.
1. I get below out put for as many columns that I use
a.
count within child:4 is :24 isAllDetailsEnabled:true
isRowAvailable:false
isRowAvailable i:false
isShowAll i:true
b. Why is table data missing. What more do I need to do?
Kindly guide.

Calling a backing bean method after load of fragment in adf

I needed to call a backing bean method after page load of fragment in adf.
I used the method suggested in:
https://community.oracle.com/message/11044570
only difference is im giving the if clause as:
if (refreshFlag == RegionBinding.RENDER_MODEL ) {
instead of
if (refreshFlag == RegionBinding.PREPARE_MODEL)
It was working fine, but page was not getting refreshed so used the code as mentioned in example:
public void refresh() {
          FacesContext facesContext = FacesContext.getCurrentInstance();
          String refreshpage = facesContext.getViewRoot().getViewId();
          ViewHandler viewHandler =facesContext.getApplication().getViewHandler();
          UIViewRoot viewroot = viewHandler.createView( facesContext, refreshpage);
          viewroot.setViewId(refreshpage);
          facesContext.setViewRoot(viewroot);
Now issue is once page is loaded and backing bean method is called, the refresh code refreshes the page and upon page load, refresh method is called again in recursive fashion.
please advise what to do in such scenario?
I tried to do selective refresh using some variable(also with static) but it does not help as page wont be refresh at all or page will keep refreshing recursively.

Use clientListener on the page load event
<af:document id=”d1″>
    <af:serverListener type=”onloadEvent”
                       method=”#{<managedbean name>.<method name>}”/>
    <af:clientListener method=”onLoadClient” type=”load”/>
    <af:resource type=”javascript”>
    function onLoadClient(event) {
      AdfCustomEvent.queue(event.getSource(),”onloadEvent”,{},false);
      return true;
    </af:resource>

How to create bar and pie graph from a backing bean in ADF

HI,
my requirement is to populate a line and pie graph based on a collection in a backing bean.
I got the solution for the bar graph with setTabularData(list data) method in one of the thread.
For bar graph,
i constructed the list for the setTabularData(list) method but it is not working with the line and pie graph.Coul'd you explain why?..
Is it different for the line and pie graph.I don't want to use adf bindings.
thanks in advance.

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 .

How to access all rows one by one of a ADF table through managed bean

Hi Experts,
Hi i am new in ADF.
Could someone help me for solving the below case?
Scenario - I have table called Test_T1 which have 4 columns C1,C2,C3,C4. Have created EO,VO and AM for test_t1.
At the time of ADF page creation i selected the option 'Automatically Exposed UI components in New managed bean' (mynewmanagedbean.java).
From Data control drag and drop Test_T1 table in the page as a ADF table.
Set the properties for C1,C2,C3 is read only and C4 is an input text.
Have add after the table and attathed button action on the managed bean mynewmanagedbean.java.
At the time of running the page Test_T1 populated with some no. of rows (like 9).
How can i access all the above rows through pressing the button without selection of any of them.
Actually i want to print all the table rows in log file at the time of pressing the button.
Thanks in advance.

Hi Timo,
Thanks a lot for your reply.
I am using the JDeveloper 11.1.2.1.0.
As previously said I am totally new in this framework. So if you explain the solution given by you then it will be help full for me.
Don't know r you agree or not for this ?
When i put your resolution in the command button bean JDeveloper said TestDataRow type not found.
What will be the type and TestDataRow and what is missing in below code or how i will declare that in below code?
Also Could please mentioned the missing thing ?

This is not the right response,browser should not reload the ADF page.It should stays in OAF page or goto another OAF page. and in other browser such ad IE,We get the right response.

hello, normally such issues are caused by a firewall/security software which doesn't recognize & therefore blocks new firefox versions. please remove all program rules for firefox from your firewall and let it detect the new version of the browser again.
