H:commandButton to render as BUTTON

Please see this enhancement request. Comments/votes welcome.

Yes, you're right.
My main reasoning was really to leave h:commandButton alone because it has been my old chum for a long time now and I don't like change; h:button is new so you can do with it what you want ; )
I'm pretty sure this change can be introduced without any impact on existing applications however, so why not?

Render radio button *after* the label when using selectoneradio?

We need a way to render the radio button before the label like so:
Yes
o
Default rendering is the opposite. Do any of you know how to do this, or another way we could solve this?
Here's our code:
     <h:column rendered="#{questions.radioButton}">
     <h:selectOneRadio styleClass="label" id="oneradioscale" layout="lineDirection" valueChangeListener="#{participants.questionareFormChange}" >
     <f:selectItems id="answerscale" value="#{questions.answerItems}" />
</h:selectOneRadio>
     </h:column>
(we need of course also a way to insert something like a

Hello Cindy,
if there is "only" a rendering problem, open an OSS message as soon as possible and let the application unchanged.

Javascript and render attribute of command button

i am setting the value of rendered attribute of h:commandButton using below code.

please help.
thanks.

JSF runs at the server side and produces HTML. Javascript runs at the client side and intercepts on the HTML DOM.
So what you're trying to do here is impossible.
If you want to render the button depending a contition in the server side, use serverside logic for that, e.g. JSF EL and/or backing beans. If you want to render the button depending on a condition in the client side, use clientside logic for that, e.g. Javascript + DOM which sets element.style.display to 'none' or 'block'.

Any way to get folio to render buttons in vector rather than raster?

Just curious if there is any way to get a folio to render a button in vector rather than raster format? I know with multi-state objects there is a nice little setting to tell it to use vector... but nothing for buttons that I can find?! I just don't like how some buttons end up looking on the Retina display on iPad...
Thanks!

Ha.. never thought about doing that. Thanks! Always the simplest solutions that seem to elude me...
Thanks again, Bob!

NullPointerException trying to render

Hello,
I have a scenario I am not sure about. I have a command button tag on a JSF page. This tag is binded to a HtmlCommandButton instance field on a backing bean e.g.
<h:commandButton type="button" value="Find"
                                       binding="#{AddCaseForm.offenderFindButton}"
                                       immediate="false"/>When the page is being rendered for the first time (initial reqest) I would like this button to be rendered depending on a certain condition. So in the constructor of the managed bean I put:
if(condition){
          offenderFindButton.setRendered(false);
      }else{
          offenderFindButton.setRendered(true);
}The problem is I am getting a NullPointerException because the HtmlCommandButton variable offenderFindButton is null. When exactly does this variable get instantiated?
How am I able to conditionally render a HtmlCommandButton if not in the constructor of the bean?
Can someone please help?
Thanks.

Hi:
Try the rendered property in the tag itself.
Like this:
1) Define a boolean member in your backing bean and getter and setter for this boolean.
private boolean renderButton = false;
2) Include the rendered property in the button tag:
<h:commandButton id="button1" value="Button" action="next" rendered="#{backBean.renderButton}" ... />
Hope it helps you.

Display buttons depends on Role

Hi,
May I Know how to displaying the buttons depends on user roles. can you give example with code it will helpful to me

Use EL expressions in <tt>disabled</tt> or <tt>rendered</tt> properties of the corresponding command components. For example, if you want to disable a button if the user is not a member of an ADF Application Role called <tt>Configurator</tt> then you may use code similar to the following:
<af:commandButton ... disabled="#{!securityContext.userInRole['Configurator']}">or if you do not want to render the button if the user is not a member of the role:
<af:commandButton ... rendered="#{securityContext.userInRole['Configurator']}">Note, that the specified role must be an ADF Application Role (defined by you using the ADF Security wizard) but not a WebLogic entrerprise group.

Problem with commandButton action listener! Help

I have a problem with the following and its driving me crazy!!
I'm getting a java.lang.NoSuchMethodException for RoomHandler.flipBoard. It seems to render the button correctly with its value. But I can't see why It can't find that method, because its definetly in the bean...
please see below
My view:
<f:view>
     <h:form id="room">
          <h:commandButton id="flipBoard" type="submit" value="#{room.flipBoardText}" actionListener="#{room.flipBoard}" />
          <h:messages />
     </h:form>
</f:view>
...and My Bean:
public class RoomHandler
     public RoomHandler()
     public String getFlipBoardText()
             String text = "";
             if (getWhiteOnBottom())
               text = "White";
             else
                      text = "Black";
             text += " on bottom";
             return text;
     public void flipBoard(ActionEvent e)
          System.out.println("Hello");
My Facesconfig..
<managed-bean>
     <managed-bean-name>room</managed-bean-name>
     <managed-bean-class>uk.RoomHandler</managed-bean-class>
     <managed-bean-scope>session</managed-bean-scope>

Sorted! I think...
Must have been a problem with myEclipse not deploying the correct class. (i think anyway)

Custom Button Rendering/Disabling with Velocity Templates [SOLVED]

I have a custom button in my application that I only want to show up on specific pages and I can't seem to figure out a EL expression that will let me disable or not render the button on the following criteria,
- The velocity template will be installed on tableForm configured groups.
- I only want the button to be activated/visable when in the 'Details' view for a specific row
- When the group has insertions permitted.
I have tried to steal some code from the *.vm files for other buttons and items used by JHeadstart, but none of the expressions seem to be solving my problem. I have always found the Data Binding through EL Expressions with the ADF very confusing to work with so any guidance would be greatly appreciated. (Is there a way to 'debug' EL expressions to see the actual data that is available to me at any given time?)
Thanks.

My Case is :
The code of my button in Custom Template :
<af:commandButton text="Zone Charge Group Details"
rendered="true" disabled="false" immediate="true" >
<f:actionListener type="oracle.jheadstart.controller.jsf.listener.DoRollbackActionListener"/>
<af:resetActionListener/>
</af:commandButton>
my Custom Template is running successfully and button appear in runtime
But I want re-write this code so that this button is binded with a method in Managed Bean
Scenario is :
when click the button in a page, it calls a method in that Bean and pass a parameter to it.
And the ouptut of this method is displayed in another page.
There is no Error message....
Please, If you don't understand anything, Ask me .
My Question is :
How to bind Button to a Method in a custom Template?

What happens to the rendered animated buttons on sub-menus

I am on a 3GB of memory MacBook Pro using Encore (CS3). Here is a description of how I have produced a working DVD...so far 3 out of 5 DVDs I have tried to render have worked.
ANYWAY...seems that Encore implodes when I try to render the same project more than one at a time. Encore chokes and I am back in the MAC OS.
HERE is my main question...every time it blows it seems to blow away the RENDERED ANIMATED BUTTONS on the secondary menu. SO each time I try this again I have to re-render the buttons taking about 1.5 hours. Why do I have to re-render...why aren't the rendered 2nd level menus SAVED.
To make it clear...after I rendered the menus...previewed...saw the buttons are animated...SAVED...try to write a DVD Disc from the Current Project...succeed...try to burn another DVD...it aborts (why...I have no idea)...I empty trash...bring up Encore again...try to preview the secondary menu...NO ANIMATION there so have to rerender and start all over.
I have been reading about compatibility of DVD disc, computer players and DVD players...what a PILE...without all the techies our there we can't make a dependable environment to create, burn and play DVDs...these companies should be ashamed...all they are doing is producing a whole bunch of frustrated producers (or lack of producing producers).
Can anyone shed a light on my problem!?!?
Thanks, --bill
p.s. Are there better forums than here at Adobe? Seems I don't get many if any replies to queries.

Bill,
A couple of questions, mainly to make sure that I understand what is happening.
1.) There are two files (an audio and a MOV), that show in the Orphanage, when you Check Project. Do they appear there BEFORE you Check Project, or only AFTER?
2.) Do they appear BEFORE in your Project Panel, or only AFTER you Check Project?
3.) Since they are Orphans, I assume that you do not intend to use them in this Project - right? Were they ever in the Project (Imported as Assets, or Timelines)?
4.) Was this Project started fresh, or did you modify an existing Project, to create it, say using a Save_As, etc.?
5.) If they were not Imported into this Project, were they Imported into another Project, that is/was being worked on coincidental to this one?
6.) Can you find these files on your system? Where are they located?
If 1.) is After and 2.) is After, then your Project might be corrupt. The Assets/Timelines/etc. are linked to the Project by XML. This can become corrupt for many reasons, most are often unknown - power dip, or hardware issue on Save, etc..
Two ways to check this theory, is to start the Project from scratch, and see what happens. Another is to use a freeware program, XML Wrench, and run the Project file through it. Aside from pointing out broken links, and other problems, it should also allow you to search for these files names in the body. Save a copy of the Project file, so you will have it untouched, and then remove any lines, that reference these files. Save_As (new Project name) and open that in Encore. Being on MAC, doesnt every data file have a finder file, associated with it? Could this finder file be cross-linked, in some way, to your real Assets?
It could be that there is a hardware issue, and this causes the links to the Rendered files to become broken, and also to link to files, that should not be included. Any other strange things with your system lately? I do not know the MAC folder/file structure, but can you do the equivalent of Windows Check Disk? If so, set it to find lost clusters, or whatever MAC calls them.
Also, being on PC, I do not know what utilities might be available for your OS, or what other programs might be causing a problem. On PCs, other DVD burning software, especially if their packet-writing applet is installed, can cause havoc with Encore and are discouraged. Anything else installed, and/or running, that you can think of?
Sorry to play twenty questions, but Id like to be as clear, as I can, on exactly what is happening, before I make too many more guesses.

Jsf and javascript to disable a button

Hi
is there a way to get the following code to disable the button called next
when the button "btn" is clicked i call the javascript function myFunc but it does not disable the button called "Next"
<html>
     <head>
          <title>Personal Info</title>
     </head>
     <body>
     <script type="text/javascript">
     function myFunc()
          document.personalForm.Next.disabled=true;
     </script>
          <f:view>
               <h:form id="personalForm">
               <h:commandButton id="Next" value="Next" action="doSomething" />
               <h:commandButton id="btn" value="button" immediate="true" onclick="myFunc()" />
               </h:form>
          </f:view>
     </body>
</html>

You should write Javascript according to the HTML source, not to the JSF code.
View the generated HTML source and base your JS on that.

[BUG]: af:commandButton rendered with requestScope variable doesn't work

This took me two days to figure out, and I wonder if it is a bug:
I have a page that can be navigated to on two occassions, let's call them "left" and "right". I want the page to know what side I came from, so I set a requestScope variable on the buttons that navigate to this page, a bit like this:
<af:commandButton action="toPage">
<af:setActionListener from="left" to="#{requestScope.sideFrom}"/>
</af:commandButton>I have two buttons on the page, one is to navigate back to the left and one to navigate back to the right. Only one is rendered, depending on the requestScope.sideFrom variable.
One says rendered="#{requestScope.sideFrom eq 'left'}" and the other says rendered="#{!requestScope.sideFrom eq 'left'}"
Only one button works, namely the one for which the rendered property evaluates to true <b>when the button is pressed</b>!! My requestScoped variable doesn't exist anymore when I press the button to navigate back so it's behavior is changed. How weird is that?
Should I file a bug?
I refuse to make it a sessionScoped variable and change it back with the return buttons Imho this is what requestScope is for.
I am on JDeveloper 11.1.1.6

Wendy,
To amplify what Timo rightly says: as JSF goes through its merry lifecycle, one of the steps is to rebuild the component tree in memory. When you use the rendered property, that particular component is not in the component tree - it's as if it doesn't even exist according to JSF. Then, when it comes time to deal with events, the event isn't seen or is ignored (I don't know which) because JSF doesn't think that component is present. As Timo also rightly says - this behaviour is why the "visible" attribute was created.

OAF Button Handling

Hello All,
Having some trouble bringing back a button on a closed Notification.
We go to a Digital Signature Page from the Initial PO Approval Notification OAF Page.
Rendered buttons with OAWebBean:
OAWebBean rootwb2 = oapagecontext.getRootWebBean();
OAWebBean wb2 = rootwb2.findChildRecursive (uiNodeName);
if (wb2 != null){
wb2.setRendered(digSigButtonDisplay);
When we return from the Digital Signature page wb2is null and we cannot render the buttons.
Does this have something to do with the Notification being in closed state??
Thanks for any help,
Bradley

Add Content button not rendered inside Portlets on edit mode

Hi,
I have a requirement where administrators will add some external content(Add content) either from taskflow or portlet and that external content (along with taskflow output) will be shown to the users based on some logic performed inside the taskflow/portlet bean code.
This PanelCustomziable should render AddContent button inside the portlet when pressing ctrl shiftE, but its no doing so? Where as the same PanelCustomizable renders AddContent button inside the taskflow on edit page? Any settings or changes needs to be done to make it work in porlet when consumed in portal?
a)taskflow cannot be selected for this purpose, as there will be only a single instance of the taskflow across the portal and it cannot retain runtime MDS changes to a specific instance (Unless we design the ADF taskflow with MDS customization layer). By default, any runtime change in one taskflow instance will be propagated to all the other taskflow instances of the portal.
(For eg.. Admin drops this taskflow onto a page1 and adds a image(external content) using the button AddContent inside the taskflow because of PanelCustomizable and close the page. He drops the same taskflow from RC only to find that the changes he done on page1 is being retained here ..its not resuable because of no MDS per instance)
So we selected Portlet for this purpose, as it has the inbuilt personalization framework. Admin can personalize each portlet instance and drops on the the same page and diff page again. But with portlets, Add Content is not rendered.
Its not just external content, the taskflow / porltet has some logic to perform and displays some output based on the ruleId which is the input parameter.
Taskflow or jsff code
==================
<cust:panelCustomizable id="pc1">
<cust:showDetailFrame text="rules content" id="sdf1"
shortDesc="rules content">
<af:panelGroupLayout id="pg1" >
<af:outputText label="RuleId" id="ot1" clientComponent="true"/>
</af:panelGroupLayout>
</cust:showDetailFrame>
</cust:panelCustomizable>

Can you please post this question to weblogic.developer.interest.portal

Hi,
i am using Workshop 8.1 (GA release july) and i have discovered a bug (ora
feature) with respect to the beta version.
i have created a simple portlet with a view mode and an edit mode. When i
place the portlet on the very first page of a one book portal, it works
perfectly. However, i have a book with three pages and placed the portleton
the second page. Now when i put the portlet in edit mode, by clicking the
edit button, i am directed to the first page of the portal and the portlet
will not show.
Inspection learned that the URL generated for the edit button, didn't
contain the _pagelabel parameter. When i added the parameter manually it
works fine.
A final remark is that the buttons in the titlebar have no icons thebrowser
can load.
hope someone can help me out,
Lodewijk
