Using EL in navigation model

Hi All,
I am using webcenter portal application. I want to check a condition and based on that condition i want to navigate to the specific page, which i think can be done with a bean call from a commandlink on action attribute.
May i know how to implement this on Navigation model as i dont know how to call a bean on url field of navigation model. Or possibly is it possible to overide the url field on navigation model with a bean method call in action attribute of command link and navigate to the specific page based on the return attribute.
We are unable to implement the navigation model in our portal, as we dont know how to overcome this.
Kindly help us
Thanks

Hi.
Bijesh is referring to visible attribute of each item of your navigation model:
<url visible="#{Your EL EXPRESSION}" id="Home"
         factoryClass="oracle.webcenter.portalframework.sitestructure.rc.AdfPageResourceFactory"
         url="page://oracle/webcenter/portalapp/pages/home.jspx">
      <attributes>
        <attribute attributeId="Title" value="HOME" isKey="true"
                   resourceBundle="com.merchan.portal.PortalBundle"/>
        <attribute attributeId="ExternalId" value="defaultMenu" isKey="false"/>
        <attribute attributeId="Redirect" value="false" isKey="false"/>
      </attributes>
      <contents/>
    </url>In visible attribute you can invoke a EL Expression (Manage Bean) to determinate if this item is going to be showed in your navigation.
If it isn't valid for your requeriment please share more details about it.
Regards.

EL for a specific page in a Navigation Model with a Pages Query

In WebCenter Portal: Spaces we are using the Default Navigation Model, which includes a Pages Query which shows all the accessible pages for the current space.
How do I create an EL Expresion that allows me to perform navigation from within a page?
<af:commandLink text="Link"
id="cl1"
actionListener="#{navigationContext.processAction}"
action="pprnav" >
<f:attribute name="node"
value="#{navigationContext.defaultNavigationModel.rootNode.childByIndex[1]}"/>
</af:commandLink>
this gets me a reference to the desired page, but only as long as the Pages Query is the first item in the model and my page is at index 1 in the Pages Query. Not very robust.
Is there any way to refer to a page by its title or something like that?
I know Business Role Pages in Spaces have a direct URL I could use, but I want to use partial page navigation wherever possible.

Jaap,
Can you describe your exact use case in a bit more detail?
Do you wish to link to a specific page or generate links to all pages (iterating through the pages) in the space? If it is the former, how do you identify the specific page? If it is the latter, consider creating a custom navigation model that contains only a pages query and iterate over this.

Expression Language to get the navigation model of the parent space

Hello,
I am hoping someone can help me with this.
Scenario: I need my sub-space to use the same navigation model as the parent.
Reason: Take a space(P) has a navigation model that queries the pages and sub_spaces(S1,S2...) in a space. Using this navigation, if we navigate to a page of a sub_space(S1) of the space, the navigation model for that sub_space(S1) will now query its pages and its sub_spaces. Instead, I want the navigation to still query the pages of the parent space(P) and the sub_spaces(S1,S2) of the parent. Effectively, the navigation contents should not change.
So, I am thinking of using an EL expression that queries the navigation model of a parent(P) to set the navigation model of the sub_space(S1).
Appreciate your help.
Thanks,
Pradyumna Nandavanam

Hi.
You can define customAttributes for your group spaces like: parentModelPath
Access it with EL Expression: #{spaceContext.currentSpace.metadata.customAttributes[attributeName]} where attribute name is +'parentModelPath'+
And with next EL Expression: #{navigationContext.navigationModel['model_path']} you can replace 'model_path' with your customAttribute value.
Kind Regards.

Forward to JSP page without using Navigation Model

How can I forward to a JSP page without using the Navigation Model?

It's done in the cardemo example in
ImageMapEventHandler.processAction() Is there a reason
for it there?Ah ... that makes sense.
That code in CarDemo was written before there was such a thing as a NavigationHandler, and we didn't have time to update it to the new approach before the EA4 release. That'll be changed before the next one. In the mean time, I'd recommend that you use the navigation rules mechanism where it works for you, because it encourages good separation of business logic and presentation logic that will lead to more maintainable applications.

Use navigation model and runtime created pages

Hi,
I have my Portal Application created in JDeveloper, with set of base pages. Pages are stored in default-navigation-model, so I could use i18n in navigation rendering. I'd also like to use runtime pages management. When I enter admin panel, I can add new pages, change order of pages created in jdeveloper, or show/hide them. However those changes are not reflected in the portal, navigation always looks the same, still displays pages I've marked as hidden - is navigation cached somewhere?
If I create new page in admin panel, it isn't displayed in navigation too. However I could click on this page title in admin panel, go to this page and edit its content - of course even then page is not displayed in the meny, none of menu items is marked a highlited.
What am I doing wrong? I followed Yannick's tutorial http://www.yonaweb.be/webcenter_tutorial/closer_look_at_navigation_model and switched from page hierarchy to navigation model. Maybe this is the reason?

I got back to your tutorial and haven't found a place where it'd be explained directly. Maybe "between the lines", but as for Webcenter newbie I haven't notice it.
I switched back to pages hierarchy. I was using navigation model to achieve i18n in navigation, however I also had problems about that, and as you suggested me once in another thread I changed page titles to PortalBundle keys and rendered values from bundles manually.
Therefore now comes the second question in this area - is it possible to use page hierarchy, runtime crated pages and still localize page titles?
P.S. As an experienced Liferay Portal developer, I really try to see any benefits of Webcenter in building custom portals area and still I can hardly find any... ;)

Use managed beans in navigation model

Hello
I have a bean called UserInfoBean.
UserInfoBean is managed in faces-config.xml and uses a Java API to determine if a user has access to a page within my WebCenter Portal. The method is called isUserAuthorized.
In default-navigation-model.xml I try to set the visible field to #{userInfoBean.isUserAuthorized} but it says that 'userInfoBean is an unknown variable'.
Do I need to manage UserInfoBean in adfc-config.xml??
Thanks!
Mitch

What's the scope of the bean?
Any specific reason why you are not using the built-in declarative security that ADF/WebCenter gives you. You can assign page/taskflow privileges without having to write any code.

How to navigate to a specific part of a page using Navigation Model

Hi....
I need to navigate to a specific part of the page using navigation models.
When I click on a link it should navigate to a div in the middle of the page instead of showing page from starting.
How to achieve this using webcenter navigation models?
Thanks.

Hi All,
Even I have the same requirement in my project.
I need to navigate to a specific part of a page instead to the top of page using navigation models.
I have a navigation model with name aboutUsNavigation.xml which have 5 links(About Us, Contact Us, Carrers, ...).
I have used the adf tree Component to show the links.
<af:tree id="about" var="node" initiallyExpanded="false" summary="AboutUs" value="#navigationContext.navigationMode
l['modelPath=/oracle/webcenter/portalapp/navigations/aboutUsNavigation'].treeModel['includeStartNode=false']}" >
<f:facet name="nodeStamp">
<af:commandImageLink id="cil2" text="#{node.title}"
actionListener="#{navigationContext.processAction}"
action="pprnav"
icon="#{node.attributes[pageFlowScope.tnBean.iconKey]}"
disabled="#{not node.navigable}"
inlineStyle="#{node.onSelectedPath ? 'font-weight:bold;' : ''}">
<f:attribute name="node" value="#{node}"/>
</af:commandImageLink>
</f:facet>
</af:tree>
All the 5 links should navigate to the about.jspx. but each to a part of the page. how to achieve this?_
Thanks..

Content Repositories in Navigation Model not visible

Hi,
I use JDev 11.1.1.7 and WCC/WCP 11.1.1.7.
I did follow the tutorial in the Oracle WCP documentation and created a connection to the Content Repository.
http://docs.oracle.com/cd/E28280_01/webcenter.1111/e10273/createconnect.htm#BGBDDHAA
Step 1 is working fine. In the Jdeveloper Application Resources window I can navigate through my content.
My problem is that when I open my navigation model and try to add a content item I have to set the url as it is shown in Figure 6-24. But I don't see my defined Content Repositories which I see in the Application Resources window. After clicking on the loupe to the right of the url inputBox I only see a folder named "Connections". This folder contains a folder called "Content Repositories". And this "Content Repositores" folder is empty.
Using drag and drop to add content from the Application Resources window to the navigation is working fine for me.
I don't remember, that I had this problem before. Can anybody help me on this.
Thanks
Tobi

Exactly,
this a problem with older versions of Explorer.
I wouldn`t worry too much, though.
Almost everyone don`t use IE6, anymore. The last I heard about it, leats than 11% of people are using it. IE 7 and Firefox are quite more popular.
Now, if you really wanna fix this, one way is to use older versions of iWeb also. You`re probably using iWeb `08. One way is to download and install iWeb `06. But, that really is a pain in the ***.

ExternalID of navigation model

Hi,
I have default navigation model with various nodes. I am able to navigate to a specific node i.e. node with externalId 'test' by using $wcUrl('test') in a html page using content presenter.
I want to access the same node with externalId 'test' in a jspx page, but $wcUrl('test') is not working by using directly in the jspx page without content presenter. Is there any alternate way to access the node in a jspx page without content presenter?
Please let me know how to access node from a jspx page.
Thanks

The $wcUrl('test') syntax is a piece of IDOC script. This will only work within a document in a Content Presenter.
If you want to create a link within a page, you can reference the externalId through the navigation model, by pointing the link to /faces/wcnav_externalId/test

Icon images in navigation model

Version: Spaces PS3
Is it possible to show images (from content server) for navigation menu item in the naivigation model. If anyone done this before please share updates.

I have already tired that. The image does not appear in the Spaces Page. howveer when I am creating the navigation model in Spaces it does appear.
I have tried a lot on modifying the inlinestyle of the decorative box containing the binding for the navigation model in my Page template. But the image does not however appears.
I am using my navigation model as a default navigation model in my Spaces.

Multiple navigation models and security

Hi,
I want to have 3 navigation models (default, A, B) but I want the "role" AA to have access to the default navigation model + A model (when connected on the portal) and the "role" BB to have the default and B one. I want to have my security here. It could be easy to make it with the page hierarchy, but I want to try it with the 3 different navigations and I'm a bit lost.
I think the answer may be in the visible attribute, but I have tried this and it didn't worked:
For A model inside default navigation:
visible: ${securityContext.userInRole == AA}
Thanks!

That's rather easy to do.
The trick is that you create a reference to an existing nav model from A so it will include the default one.
When you go the administration console and open the configuration tab you can define the default navigation model. For this you can use expression language so you just have to write a managed bean that returns the path to the navigation model.
Something like this:
public String getNavMode(){
if(userInARole)
return "oracle/webcenter/portalapp/navigations/modelA.xml";
if(userInBRole)
return "oracle/webcenter/portalapp/navigations/modelB.xml";
return "oracle/webcenter/portalapp/navigations/default.xml";
}I haven't tested it but it should work. It's also possible that you can ommit the .xml in the filename.

You will need custom code for this, but since the amount is minimal and this is Stack Overflow I assume that won't be a problem. You will want to make your own listview web part that queries the list using ListViewByQuery. An example can be found here:
