Hi,
this is ashish here. Please let me know which templating mechanism is best for use with ADF Faces.
1.Tiles or
2.ADF Region or
3.Facelets
Please reply as early as possible.
Thanks in advance.

Hi Frank,
Can you please suggest me a tutorial(.pdf) or a sample or hyperlinks where i can find the right stuff.
Thanks in advance.

ADF Region Refreshing Mechanism

Hi all,
i have a doubt on how ADF region refreshing mechanism works. Let me explain my doubts with an example. Suppose you have a page .jspx inside whom you put a region with the following relevant properties:
- Refresh: ifNeeded
- Activation: deferred
- Parameters:
ID Value
param1 #{pageFlowScope.myBean.param1}
param2 #{pageFlowScope.myBean.param2}
paramN #{pageFlowScope.myBean.paramN}
As you can see, the region is instructed to re-execute its task-flow everytime any of its parameters change. What i don't understand is if the parameters must be changed in particular ways that let the region know that it must be re-executed or they can be changed in any way, for example from within the method of a managed bean: returning to the example above, if inside myBean i have a method like the following:
public void refreshRegion(){
setParam1(new Param1());
the region gets re-executed everytime i call this method?
If not so, could you please explain how exactly the region detects that one of its parameters is changed and then it must re-execute its task-flow?!?
Thanks in advance!
Bye!
Fabio

Hi,
thanks for the reply. Is there some reason in particular to use variables stored at requestScope level? The mechanism used by regions to refresh theirselves don't should be the same regardless the scope at which their parameters are stored?
As a technician, i imagine that the only way regions are able to automatically detect the need to re-execute their task flow is putting theirselves in constant listening to eventual changes in the value of their parameters. As far as i know, this is the only way for regions to detect the exact moments when refresh is required, despite the way their parameters are updated. If this is not the case, then i think the assumption according to which regions are able to refresh theirselves no matter the way their parameters are changed is wrong, and i'd like to know the real mechanism that hides behind the refresh of ADF regions.
You said that:
" Now, in any of the server code, if you are changing anyone of the above requestScope values, the taskflow would be re-executed "
Please, let me ask you: even if the code that changes the value runs inside a thread different from the "ADF thread"?
Thanks again,
Bye!

How to reset viewScope for a particular ADF region

I have following usecase.
I navigate to a page (say cloud home page). while calling this page couple of parameters are set in view scope.
1. viewScope.keyAttrs.target
2. viewScope.keyAttrs.type
The page has a ADF region ( say inventory) embedded.
For this region I want above parameters in view scope to be null. Can I set a flag or something to make it null?

My requirement is specific to Enterprise Manager so closing the thread.

How to create ADF region without Task Flow

I want to divide my page into different regions, but I don't want to have any bounded task flow under each region. I want to include Page Fragment inside the Region.
I find the example of creating Region using some page flow, would you please help me, how to create Region that contains only page fragment, actually the problem I am facing, I don't know what I will provide in value attribute in Region tag, that is expecting some Region Model.

Hello, RajeshBiswas.
A solution could be to generate 'MultiTaskFlow' for indeterminate number of regions or multiple regions on the same page.
It would be necessary to create a single file to define all participating 'TaskFlows' on page:
1. Select 'new -> ADF Task Flow (JSF/Facelets)'
2. May include all 'jsff' files as:
<task-flow-definition id="genericTaskFlow1">
    <default-activity>case1</default-activity>
    <view id="case1">
      <page>/pages/case1.jsff</page>
    </view>
    <use-page-fragments/>
</task-flow-definition>
<task-flow-definition id="genericTaskFlow2">
    <default-activity>case2</default-activity>
    <view id="case2">
      <page>/pages/case2.jsff</page>
    </view>
    <use-page-fragments/>
</task-flow-definition>
It should create a Managed Bean to implement the List of Task Flow Bindings:
1. Create a new Class with de following code:
    private List<TaskFlowBindingAttributes> mTaskFlowBindingAttrs = new ArrayList<TaskFlowBindingAttributes>();
    public MultiRegionBean()
        TaskFlowBindingAttributes tfAttr = new TaskFlowBindingAttributes();
        tfAttr.setId("region1");
        tfAttr.setTaskFlowId(new TaskFlowId("/WEB-INF/.../ADFTaskFlow.xml", "genericTaskFlow1"));
        mTaskFlowBindingAttrs.add(tfAttr);
        tfAttr = new TaskFlowBindingAttributes();
        tfAttr.setId("region2");
        tfAttr.setTaskFlowId(new TaskFlowId("/WEB-INF/.../ADFTaskFlow.xml", "genericTaskFlow2"));
        mTaskFlowBindingAttrs.add(tfAttr);
    public List<TaskFlowBindingAttributes> getTaskFlowList()
        return mTaskFlowBindingAttrs;
2. Define this new class into the 'adf-config.xml' file as Managed Bean with 'pageFlow' scope.
<managed-bean id="__1">
    <managed-bean-name>managedBeanName</managed-bean-name>
    <managed-bean-class>className</managed-bean-class>
    <managed-bean-scope>pageFlow</managed-bean-scope>
</managed-bean>
At the page definition, add a MultiTaskFlow inside <executables> tag:
    <multiTaskFlow id="multiTaskFlow1" taskFlowList="#{pageFlowScope.multiRegionBean.taskFlowList}"
On the page, insert regions in the desired locations. For example:
    <af:group id="g2">
        <af:panelAccordion id="pa1" inlineStyle="width:50%; height:400px;">
                <af:showDetailItem text="showDetailItem 1" id="sdi1">
                <af:region id="r1" value="#{bindings.multiTaskFlow1.taskFlowBindingList[0].regionModel}" >
                </af:region>
                </af:showDetailItem>
        </af:panelAccordion>
        <af:panelAccordion id="pa2" inlineStyle="width:50%;">
                <af:showDetailItem text="showDetailItem 1" id="sdi2">
                <af:region id="r2" value="#{bindings.multiTaskFlow1.taskFlowBindingList[1].regionModel}" >
                </af:region>
                </af:showDetailItem>
        </af:panelAccordion>
    </af:group>

Adf region is not displaying anything

Hi,
I am using adf region to display the data.For this I have created one bounded task flow with page fragments.
In the page fragment I created one output tag to display something.this page fragment is dropped in task flow.
Then I made one JSP page and drag the task flow and drop it as the region.The problem is it not displaying any data.
I am using jdev 12. Can you please tell me whether I am doing anything wrong.
Thanks,
Harsh

What do you mean by
Then I made one JSP page and drag the task flow and drop it as the region.
Did you create a jspx page or a jsf page. Depending on the fragment type it only works on a jsf page (jsf 2.0 page). 12c default is create fragments as 'Facelets' which only work in jsf Pages. If you want to use a jspy page you have to create the fragment as 'JSP xml'.

Dynamic JDBC Credentials and using ADF Region ERROR

Hi,
I used solution by Steve Muench, Dynamic JDBC Credentials (for ADF Faces Rich Client)
(129. 11g Dynamic JDBC Credentials for Model 1, Struts, Trinidad, and ADF Faces Rich Client 11.1.1.0.0 06-AUG-2008), but it works not correct in case of using ADF Dynamic Region (or simply ADF Region).
I have added in ViewControllerJSFRichFaces a page (main.jspx) including ADF Dynamic Region consisting of 2 simple tasks flows. Action of the Login button, if login and password are correct, redirect to main.jspx
There are to cases.
1) Login and password are correct:
In this case all work fine.
2) Login and password are not correct:
It does not work. redirect to login.jspx does not occur as it is expected, but the following page (main.jspx) is loaded, herewith thrown exception: oracle.jbo.DMLException: JBO-26061: Error while opening JDBC connection.
I would be very grateful you for help.

Hi,
hard to say from your description if this is a bug or an implementation problem. Note that errors that occur in regions are not handled by the exception handler of the the parent page and require special handling within the region. In other words, if the problem is in the region then it needs to be handled in here. I think the right strategy here is to not show the region until a valid connection exist. Is the login performed from the parent page ?

ADF Region not getting refreshed after Commit

Hi everyone!
I'm having some trouble with a region that is disturbing me for more than 2 weeks, its true guys, I tried everything!!
My parent page is a normal ADF .jspx page that contains inside it a task-flow call. The first task-flow activity is a router, after sending a String
to router it chooses the region activity that fits the page (in this example I always pass the same value, same String).
After the router is called then it delegates to "ExecuteWithParams" method call before calling my final region that have its query executed with
parameter set inside task-flow.
The region is refreshed (refresh="ifNeeded") when I change row inside a table in ParentPage, all fine here.
The problem is:
- After any Commit (with navigation case or executable binding) is issued inside Region the region save its state and does not refresh anymore, even if task-flow parameters change.
Already tried CacheResults="false" on iterator too.
I'm using Jdeveloper 11.1.2.1.
Thanks in advance!!

Hi,
so I think the shirt summary of your problem is that an ADF region doesn't refresh after it issued a commit. Sounds like a bug to me if this reproduces in a test case. Do you have a testcase based on the Oracle HR schema ? If so, send it my way in a zip file you rename to ".unzip". My mail address is in my OTN profile. Note that bugs I file are not visible to customers. So if you need to keep track of any state of the issue, you need to file a service request with support yourself.

Are Oracle going to build a Webutil library for ADF ?

Hi,
We have a customer who has a forms app that uses Webutil to interact with many things such as the registry, DLL's etc.
One obstacle we have in trying to sell a rewrite in ADF to them is the lack of Webutil-type functionality in ADF. If Oracle developed a Webutil library for ADF we would be able to sell the product much easier.
Do any of you Oracle guys know if it is on the cards ?
cheers
Edited by: Dom Klein on Nov 2, 2009 11:29 AM

Hi,
Would you explain what "Forms is already on the page" mean? Thanks.
This means that if you want to integrate Forms with ADF and Forms is embedded as an Applet on an ADF page
BTW: There should be a mechanism that would allow ADF to have trusted access to client machines.
ADF has nothing to do with this. In general HTML based content cannot access the client desktop except for file uploads for security reasons. If browser vendors could agree on a standard that allows signed JavaScript to perform trusted client access then this could be solved. However, signed JavaScript is only supported by Netscape browsers and is not available anywhere else. In Java Applets, like Forms uses it, the Applet sources are signed - as there is a standard for this - allowing Java to access the client.
Webutil was a significant breakthrough for Forms.
Yes. It is a corner stone that bridged the functionality gap between client server and web based forms
I'm currently slogging through various ADF tutorials. the documentation is ALL OVER THE PLACE. I'm struggling with trying to find a way gain access to the current application instance that would give me access to active view objects. The ADF documentation is PAINFULLY opaque on this issue for this newbie.
Forms had 2 developer guides to the time we printed manuals (a basic introduction and an advanced manual). Adding the Graphics guide and the Reports guise, all in all the documentation was provided in 4 books. ADF and the related technologies are way more complex for a beginner, but once understood also more powerful than Forms. The main documentation - surprise surpise - is provided in 4 books. The ADF developer guide, the Web developer guide, the desktop integration guide and the mobile development guide. As a beginner, the first two guides is what you need - start with the ADF developer guide.

Related documentation, which is runtime specific, is then provided in the FMW documentation

How can i create datasource on apache server for ADF application?

Hi All,
i my use case i have created simple adf application using ADF BC and want to deploy on Apache server 6.x.
So my question is that how can i create Data Source i have goggling and find two different way to do this.
1. write following line of code on apache server conf/Context.xml file.
<Resource name="jdbc/TestDB" auth="Container"

              username="jagrandb" password="jagrantest" maxActive="20" maxIdle="10"
              maxWait="-1"/>
but when i have used this way i got following exception.

Best laptop for ADF development?

Hi all,
The next week I want to buy a new laptop for adf development and the question is What are the optimal requirements to run jdev and deploy big apps to the integrated weblogic without lost my hair.
I know this is a well commented issue in this forum but the tecnology change quickly.
Jhon

Based on my experience, I can post below comments:
I used Windows7 with 4GB Ram and I5 processor (32 bit) in previous project and I started loving mac so I am using Mac (Mountain Lion 10.8.3 version, I7 processor with 8GB Ram) now for my current project but somehow I notice my mac machine hangs a lot though it is of higher configuration and also still has some jdeveloper issues like (some time my BC tester fails i.e. testing model from AM) fails adhoc basis. However all these comments are applicable only for my machines and I may be wrong as well. Just thought of sharing my experiences with Windows/Mac.
Another point, if you want to develop any ADF Desktop Integrator applications, only windows OS supports and MAC has not support for it.

Ravi Nuka.

What are the best coding standards for ADF 11g?

Hi,
Do we have any link that will suggest the best coding standard practices used for ADF 11g?
I am looking out from the perspective of some standards that can be defined before starting my project to know the team on how to
1. Minimize Duplicity and max reusability of code
2. Package the code
3. Resource bundle usage and its calls
4. Maintainning format consistency eg. date display format, number format
5. Exception handling
6. Logging
7. Namiing conventions
Also then we might have standards on
1. Task flow dev.
2. EO and VO creation standards
3. UI development standards [purely ADF component based]
Thanks in advance
Edited by: user8925296 on May 26, 2010 3:24 PM

The ADF Enterprise Methodology Group has a page on standards that gives you a starting point on many of your questions: http://groups.google.com/group/adf-methodology/web/adf-coding-standards
