Programmatically adding declarative components (ADF 11g 11.1.1.5.0)

Hi All,
We have a number of declarative components that we are utilizing within our ADF implementation, I am trying to create one of those components in a similar fashion to how I create a Rich Input Text (for example)
RichInputText text = new RichInputText();
panelForm.getChildren().add(text);
This doesn't seem to work if I replace the "RichInputText" with "MyDecComp" class, where the declarative component doesn't render. Is there any way to achieve the same outcome with the declarative component as the normal JSF / ADF component.
Looking forward to your reply.
Regards,
Younis

Thanks for the link. We are trying to write a template as described on this link - Help on JSF Page Template
However we are running in to issues after defining the attribute.
Can anyone help?

Programmatically adding objects/components

Hi guys,
I'm just new to Java and the Java Studio Creator.
Anyway, I would just like to ask how you can programmatically add objects or components after each event, let's ay after every press of a button, another text field, output text, image or whatever component, is added on the page.
I'm trying to do an application wherein the user can enter number of rows they want to show in a table (grid panel) which has by default, 5 columns with one image inside every column. If the user enters 2, the table should now have 2 rows that are identical.
Hope you can help me with this problem guys. Thanks in advance!

Anyway, I would just like to ask how you can
programmatically add objects or components after each
event, let's ay after every press of a button,
another text field, output text, image or whatever
component, is added on the page.The components of a page are organized into a tree structure with parent-child relationships. Therefore, all you need to do is acquire a reference to the component you want to be the parent, create a new instance of the child, and add the new child to the parent component's list of children.
In a page bean, it looks something like this. Assume you want to add a new Output Text component inside the form component named "form1". Because Creator binds all of the components to properties in the page bean, finding this component is easy -- there is an instance variable with the same name that contains a reference to this component. So, you would do something like this:
UIComponent parent = form1; // Get reference to parent
HtmlOutputText newOne = new HtmlOutputText();
newOne.setValue("This is the text value");
// set other properties as needed
parent.getChildren().add(newOne);The value returned by getChildren() is a standard java.util.List, so you can insert children anywhere in the list, remove them, reorganize them, or whatever is needed.

ADF 11g Declarative Components

Declarative components rock! now is there a way to use them with a managed bean, for example click a button to load a table of data. After you wire this up with the managed bean, partial rendering and deploy as library it will work in a new project as a new component. However the partial submit and trigger doesn't seem to stick. It does a full page submit. Is there a solution for this???
thanks.

Hi,
I have a DC, which contains a panelCollection with a toolbar and buttons in it. The panelCollection's child is a facetRef. On a consuming page I insert into the facet a table.
How can I get the toolbar's buttons get updated, once the table's contents have changed?
Particularly, disabled properties of the buttons are exposed as attributes of the DC. On the consuming page the attributes are bound to enabled properties of a commit and a rollback binding actions. Initially the buttons are disabled. When I change a cell's value it would be nice, if the buttons would be enabled in response without refreshing the page or invoking an execute on an undelying VO/iterator.

ADF Mobile: Templates, Reusable regions, Declarative components

Hi,
Unfortunately the developer guide has no mention about how to create page templates, re-usable regions, and declarative components. Does ADF Mobile currently support them? Please shed some light.
Thanks
Srini

Not right now.
But you can use the deploy as feature to develop reusable features that can be shared among applications.

JDeveloper 11.1.2.3, ADF Faces: aberrant behavior declarative components

Strange things have been happening with my research into declarative components.
1. declarative component cannot be used the within the same project it is defined. only in a separate project which consumes it as an adflib
2. periodically, in the componentdef property inspector for my declarative component would miss displaying all values I defined for "Facet Definitions, Method Signature, Methods". Closer inspection of the code reveals that somehow, the afc tags disappeared! so the code for something like a method attribute would look like:
<method-attribute>
<attribute-name>
commit
</attribute-name>
<method-signature>
void method(javax.faces.event.ActionEvent)
</method-signature>
</method-attribute>
...instead of:
<afc:method-attribute>
<afc:attribute-name>
commit
</afc:attribute-name>
<afc:method-signature>
void method(javax.faces.event.ActionEvent)
</afc:method-signature>
</afc:method-attribute>
...3. during design time, the ActionListener attribute of a button (in the declarative component definition) shows up under "warning node" and states "Reference comp.nameofactionlistener" not found.
Code will run but there are many warnings similar to this.
anyone else on 11.1.2.3 have similar issues working with declarative components? i'm trying to find steps to reproduce but havent stumbled upon it yet.

Wes,
1) is documented at http://docs.oracle.com/cd/E35521_01/web.111230/e16181/af_reuse.htm#autoId21
2) and 3) I personally have not stumbled upon, but if you have a reproducible test case you should open an SR or make an entry in the ADFEMF issue tracker (http://java.net/jira/browse/ADFEMG side is currently down :()

ADF 11g: turn off validation pop-up windows

Hi all,
Does anyone know how to turn off the pop-up messages with ADF 11g? I am using Jdeveloper 11.1.1.4.0.
I need to display the error messages on the page. I have added Message components to the page to display the error messages. Now it displays the errors twice. I need to turn off the pop-up message now.

Do we have a preprocessor or interceptor layer in ADF 11g?

Hi,
I am working on JDev 11g and ADF 11g.
For my project we have provided a login screen. Now I want the logged user to be authenticated and authorized.
This has to be done through the tables/values available in database [oracle 10g] and NOT declaratively.
For this, I want to have a preprocessor OR Interceptor layer that will do the required authentication and authorization. So now based on the output of this layer I will show the result to the user.
Want to know
1. How can this be achieved in ADF?
2. What steps should I follow
3. Are there any limitations that I need to be aware of?
Thanks in advance.

.. to add to the previous answer
- you can authenticate users against a database infrastrcuture using WLS. User names and roles can be added to the privileges of the authenticated users this way. Using ADF Security, JAAS permissions are declaratively added to application roles, which are mapped to user roles. This way the framework does it all for you
- if you want to implement custom security, no standard security, the you have various hookpoints to use
1) PageLifecycle customization - checks on teh PageDef level in ADF if users are allowed to access this apge. For this you would need to know about the requires access permission and look it up in your database tables
2) ServletFilter - handle the incoming request first and determine if the request is for a protected resources
3) Task Flow initializer method / method call activity - check authorization on task flow entry
4) PhaseListeners - similar to servlet, check the incoming request for authorized resource access
5) Use managed beans and EL on pages to show/hide content
As you see, using ADF Security is a lot easier to use than a hand crafted solution. However, its possible
Please see the Fusion developer guide documentation for more infromation about lifecycle handling and customization

Lightweight alternative to Declarative Components?

Hi,
Is there a simpler, lighter way to extract part of an ADF page into a re-usable tag that can be used instead of the Declarative Components feature?
In my application, I have a table which displays some data from a VO. Some columns are links, and there are also various buttons in and around the table that allow the user to perform a set of common actions on the table contents. I don't want to have to replicate this into all my various pages, I want to extract this into a reusable 'tag'.
This is not a component that will be useful throughout the organisation, it's just a simple component that will be used a few times in this one application. My first idea was to use the ADF declarative component feature, but this requires deployment of a seperate JAR. I've followed various tutorials now on creating a jar then including it into my project, but I haven't succeeded so far (for some reason the jar I create doesn't seem to contain the Declarative Components I have defined). Can I not simply define some components in my own application and use them within that application without the JAR deployment step?
I've also tried going the JSP tag route, but I need to pass objects such as the backing bean and the view object iterator to the tag and when I try and add a tag attribute with deferredValue="true", I get an error from the app server like:
/WEB-INF/tags/attachments.tagx: Line # 9, <jsp:directive.attribute name="backingBean" required="true" deferredValue="true" type="java.lang.Object" xmlns:jsp="http://java.sun.com/JSP/Page"/>
Error: Invalid attribute "deferredValue", for the attribute directive with name " backingBean " when the tld version is not 2.1

     at oracle.jsp.parse.JspParseState.createTagParser(JspParseState.java:943)
     at oracle.jsp.parse.JspParseTag.genXMLSrcTag(JspParseTag.java:919)Even though my implicit.tld does have version="2.1".
My third and final idea was to create a jsff and include it in the page via f:subview and jsp:include, however I can then only pass string type parameters (jsp:param) to the fragment. This isn't adequate, since I need to pass backing bean, view object iterator, etc.
Surely I'm missing an easy way to do this. Any ideas?

I've now succeeded in creating a Declarative Components library and importing those components into my project. It's a rather long winded process but if it works I guess it'll do.
I've created a component called 'attachments', but I'm now getting the following exception when attempting to use the components in my page:
java.io.FileNotFoundException: MDS-00013: no metadata found for metadata object "/components/attachments.jspx"

     ...Another post on the forum says the solution is to create a pageDef file for the jspx, however I can't create a pageDef for a component as far as I can tell.
Is there a solution here? Can MDS and Declarative Components be used together?

Frames in ADF 11g

We have a requirement to split the page into 3 parts (basically 3 frames on the page). Frame on the left would contain links to the pages on the right which would be driven by a POV frame at the top. My question is do we have any specific component in ADF 11g to implement basic html frames ( like panelSpiltter) or would it be better to implement the page using basic html frames.
Also, for getting the list of afh components, do we need to add any specific library or have these components been removed in ADF 11g.

They are in the Trinidad set of components - but I would only suggest using those if you can't achieve the layout you are looking for with a combination of the layout components we offer in ADF Faces RC.

How to access/identify components in JSF Declarative Components?

Hi,
I am beginner on ADF. Trying to build first Declarative Components.
Use Case is as follows -
I have put 2 InputTexts in Declarative Component.
Want to set some value in second InputText (txtAddressLine2) in Validator/ValueChangeListner method of first InputText(txtAddressLine2).
<?xml version='1.0' encoding='windows-1252'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
<jsp:directive.page contentType="text/html;charset=windows-1252"/>
<af:componentDef var="attrs" componentVar="component">
<af:xmlContent>
<component xmlns="http://xmlns.oracle.com/adf/faces/rich/component">
<display-name>Test</display-name>
<attribute>
<attribute-name>
AddressLine2
</attribute-name>
<attribute-class>
java.lang.String
</attribute-class>
</attribute>
<component-extension>
<component-tag-namespace>Address3</component-tag-namespace>
<component-taglib-uri>/Address3</component-taglib-uri>
</component-extension>
</component>
</af:xmlContent>
<af:inputText label="Address Line 1"
binding="#{backing_Address3.txtAddressLine1}"
id="txtAddressLine1"
validator="#{backing_Address3.txtAddressLine1_validator}"
autoSubmit="true" immediate="true" rendered="true"
valueChangeListener="#{backing_Address3.txtAddressLine1_valueChangeListener}"/>
<af:inputText label="Address Line 2" binding="#{backing_Address3.txtAddressLine2}"
id="txtAddressLine2"
validator="#{backing_Address3.txtAddressLine2_validator}"
autoSubmit="true" immediate="true"/>
</af:componentDef>

</jsp:root>
This is sample I am working on.
I am trying following approaches in bean of Component itself.
Approach I: This does not give any error, value is not set in txtAddressLine2
this.getTxtAddressLine2().setValue("Some Value");
Approach II: Not able to access txtAddressLine2 using findComponent() method
UIViewRoot uiViewRoot = facesContext.getViewRoot();
RichInputText inputText;
inputText = null;
if (uiViewRoot.findComponent("txtAddressLine2") != null) {
System.out.println("Found ");
inputText = (RichInputText)uiViewRoot.findComponent("txtAddressLine2");
inputText.setValue("my value");
} else {
System.out.println("Not Found "); //Always not found
Can anybody tell me correct way to access components and set their values inside Declarative Components itself?

Thanks buddies....its resolved!
This is how I have done it -
Components have these 2 Input Texts :
<af:inputText label="Label 1" id="txt1" autoSubmit="true" immediate="true"
binding="#{DC2.txt1}" validator="#{DC2.txt1_validator}"/>
<af:inputText label="Label 2" binding="#{DC2.txt2}" id="txt2"
immediate="true" autoSubmit="true" partialTriggers="txt1"/>
Code in Component Bean setting value is as follows:
RichInputText txt22;
txt22 = getTxt2();
txt22.setSubmittedValue("Some Value");

Declarative Components field binding

Can we bind a View Object to declarative component? I want to have a declarative component and whenever that declarative component would be used, it would be used with the same view object so i feel it extra work to bind all the attributes to view object's attributes whenever declarative component has to use. I want t create the component (declarative) and get bind it with a view object somehow and use it without every time going through to bind to view object or bind individual fields to view object's attributes. Any suggestions??

Hi,
this is not what declarative components are for. Think of declarative components as standard JSF components, which you would not build tied to a specific model. If you need to wire a declarative component to a View Object then you expose an attribute on the declarative component that the consumer of the component the uses EL on to bind it e.g. to the ADF binding layer

JDeveloper and ADF 11g Release 2(11.1.2.0.x) compatible WebCenter Version

We are looking to upgrade ADF to 11.1.2.0 and looking for WebCenter compatibility.
Could you please let me know WebCenter compatible version for JDeveloper and ADF 11g Release 2 (11.1.2.0.x) ?
Thanks
JP

Looking at 11.1.2.0.0 note on
http://www.oracle.com/technetwork/developer-tools/jdev/downloads/index.html
and seeing, "This version of JDeveloper doesn't include the SOA and WebCenter pieces - to use these components you'll need to download Oracle JDeveloper 11.1.1.5.0."
Does that mean, 11.1.2.0.0 can't be used with WebCenter?

How to set the disable,visible property in declarative components.

We have used one declarative component. It consists of 5 buttons (add,delete,save,delete,print). In all of our pages, this declarative component is used. We could bind methods and was able to use each pages seperately (by linking the methods in the backing bean)
But for implementing the DISABLE,VISIBLE properties, we have added the attributes for this and refered this to the corresponding disable and visible property of the button. In the page all these properties where reflected. But at the runtime these buttons are not coming.
Can anyone advise how can we set the disable,visible property in declarative components.

Hi vikram ,
i hvnt initialized the properties ,
in my declarative component i have one button say Save button and i want to config 2 properties Disable and Visible
i added two attributes ( java.lang.Boolean ) say disablr_btn ,*visible_btn* and mapped wth the Save button Properties Disabled and Visible using expressions
Now the button is invisible while running the page.
if i remove the mapping from properties Disable and visible , the button is visible
should i init the properties in faces config , i dnt knw hw to init the properties
pls advice
