Invoke FileDownloadActionListener on page load

I have list of file file download links and i want to refer this file downloads , So i want to refer this download links in other pages or sites which should directly link
For eg http://mysite.com/context-root/faces/Download .jspx?file=myfile.zip&mode=download , so after loading the page downloa should starts automatically after the page load , whats the best way to do it ?

Hi,
You can have a client listener at document level (of type load) and queue a server event. In the server method you process the button click (for which you've added af:fileDownloadActionListener).
Check this thread for achieving this in programmatic way.
invoke af:fileDownloadActionListener programmatically

Issue with invoking javascript during jspx page load

Hi All,
I am using Jdeveloper 11gR2.
I have embedded a small javascript snippet in the adf page to invoke a managed bean method during page load.
<af:serverListener type="onloadEvent" method="#{AMBean.click}"/>
 <af:clientListener method="onLoadClient" type="load"/>
 <af:resource type="javascript">function onLoadClient(event) {AdfCustomEvent.queue(event.getSource(),"onloadEvent",{},false); return true;}</af:resource>
In the associated managed bean method, I want to change the setContentStyle of all the input text field found during run time -
 System.out.println("There control is inside the listeners");
 FacesContext facesContext = FacesContext.getCurrentInstance();
 System.out.println("facesContext"+facesContext);
 UIViewRoot root = facesContext.getViewRoot();
 System.out.println("root - " +root);
 RichPanelFormLayout formClass = (RichPanelFormLayout)root.findComponent("db");
 System.out.println("formClass - " + formClass);
 List<UIComponent> uiComponentList = formClass.getChildren();
 for (UIComponent uiComponent : uiComponentList) {
 if (uiComponent instanceof RichInputText) {
 //((RichInputText)uiComponent).setDisabled(false);
 //((RichInputText)uiComponent).setColumns(100);
 ((RichInputText)uiComponent).setContentStyle("width:200px");
 System.out.println("uiComponent - " +uiComponent);
Currently the javascript function "queues" the setContentStyle action for an action event, i.e. during the initial page load, the properties of text fields are not changed, however as soon as i click any button on the page, the text field width is reset to what I have defined in setContentStyle property.
Is there a way to execute setContentStyle action as soon as the page loads initially?
Best Regards,
Ankit Gupta

Hi Arun,
Many thanks for the revert.
The exact Jdeveloper version is 11.1.2.4.39.64.36.1.
I have a scenario where in the the user will be navigated to a page to display an input form, but the underlying VO will change during runtime which means depending on the value selected by the user, he will be shown an ADF form accordingly.
Also during runtime, the number of input text fields will change according to the number of attributes in underlying VO.
Kindly advise based on the use case explained above.

Creation of components on page load

Hi All,
My question stems from the answers I received in these forum posts:
- http://forum.java.sun.com/thread.jspa?threadID=5262963
(how to dynamically add components to a specific position in the page)
- http://forum.java.sun.com/thread.jspa?forumID=427&threadID=5262253
(how to register a PhaseListener to trigger before rendering the response)
What I'm trying to do now is to dynamically create components inside a container as soons as the page loads. To do this I have placed the following code inside the beforePhase() method of my PhaseListener:
FacesContext.getCurrentInstance().getApplication().addComponent("Label", Label.class.getCanonicalName());
Label label = (Label)FacesContext.getCurrentInstance().getApplication().createComponent("Label");
label.setText("Hello World!");
panelGroup.getChildren().add(label);I've also modified my JSP page as follow:
<webuijsf:panelGroup binding="#{TestPage.panelGroup}"/>I've tried debugging the code, and my PhaseListener is definitely working (as my code gets executed), but when the view is rendered the label isn't displayed at all. It works fine, however, if I put the code inside a method and connect an actionListenerExpression to it which gets called when a button is pushed.
Any ideas?
Ristretto

Hi Ristretto,
A couple comments. First, if the "Label" component is already declared in a faces-config.xml file somewhere, you don't need to re-register it w/ JSF... and you certainly don't need to do it each time your code is executed. If this is the Woodstock Label component (as the "webuijsf:" prefix implies for your other components), then you don't need to do this. So you can remove the first line of code (the addComponent() line).
From what you've described, I would think it should work. Your panelGroup variable is the same instance of the object returned from the binding in your JSP, and the phase listener gets invoked before anything gets rendered. If that happens, everything should work as you want it to. Obviously something's not right, though... and unfortunately I don't see it either.
Why do you want to do this in a phase listener instead of during your binding?
I would not recommend creating a hierarchy of managed beans that register themselves as phase listeners and provide behavioral functionality for your application. This is very likely to be difficult to maintain, will cause every page to execute these phase listeners, and simply cause you problems. That said... there may be cases where phase listeners are a good fit in order to execute code on every request, so maybe what you're doing is ok for your use-case -- that's your call. :)
Let me show you a complete, runnable example of how JSFT can do exactly what you described below w/o writing any Java code or compiling, etc.:
<sun:page>
<sun:html>
<sun:head title="Woodstock Example" />
<sun:body>
<sun:form id="form">
<sun:panelGroup id="panelGroup">
 <!afterCreate
 createComponent(type="sun:label", id="label", parent="$this{component}", component=>$attribute{comp});
 setUIComponentProperty(component="$attribute{comp}", property="text", value="Hello World!");
 />
</sun:panelGroup>
</sun:form>
</sun:body>
</sun:html>
</sun:page>The "sun:" tags are the same as the "webuijsf:" tags (woodstock) you are using. If you use the facelets syntax w/ JSFT, you can map the prefix to "webuijsf:" also. When run, the panelGroup part of the page looks like this in the browser's source:
<label id="form:panelGroup:label" class="LblLev2Txt_sun4">
Hello World!
</label>The "createComponent" and "setUIComponentProperty" handlers are builtin to JSFT and do what your simple example needed, however, using a simple annotation you can create your own custom handler to do anything you want (assuming your performing some logic or retrieving data from somewhere to create these components on the fly). These handlers demonstrate that there are better alternatives to "managed beans." Managed beans tend to get tied to a particular page and scope... but logic should neither be tied to a page, scope, or a particular use-case. By allowing parameterized handlers to exist, you can invoke them from anywhere. This is the re-usability you are trying to achieve through inheritance without the overhead that you will incur.
If you'd rather add the component during the rendering phase instead of the restore view phase (afterCreate is during the restore view phase in JSFT), you can use the "beforeEncode" event. And furthermore, you don't have to associate the event w/ the component in which it should be associated with (although you can)... for example you could put this event at the top of the page so that it gets invoked at the beginning of the render response phase:
<!beforeEncode
 getUIComponent("form:panelGroup" component=>$attribute{parent});
 createComponent(type="sun:textField", parent="$attribute{parent}", component=>$attribute{comp});
 setUIComponentProperty(component="$attribute{comp}", property="text", value="#{pageSession.foo}");
/>This causes a woodstock textfield to be added before rendering the page. However, unlike creating a component tree, rendering happens each time the page is refreshed. So, this code could potentially get invoked many times... just add a button w/o any navigation rule and you'll see it add a new text field each time you click the button.
Last... you may want to consider using facelets way of composing pages. This allows you to create a template which may include page-based phase listeners, or events (as shown above), or bindings... as well as the obvious header / footer and other template content. This again is a much better re-use strategy than maintaining a bunch of JSPs. And JSF 2.0 is going to emphasize Facelets syntax over JSP for this reason.
Good luck!

Query activated on page load

Hi
I have a query region with autoCustomizationCriteria on my page. I set some initial values for the query fields. How can I activate the query on page load so the users can see the results based on the default values when the first visit the page? Currently they have to click the search button.
Thanks

In the processRequest of your controller you can invoke a method in the AM which in turn invokes a method in the Search VO which sets the where clause and executes the query.

Populate LOV on page load

Hi,
I have a requirement that when the OA page is first time invoked, there is an Account ID request parameter that will be passed. I need to set the Id in LOV so that it will display the value on page load.
Example: AccountID=123 is passed as request param. Then LOV should display "Account123" on page load. Account123 is display value and 123 is key value.
Thanks,
Bhavnesh.
Edited by: bhavnesh_p on Feb 25, 2009 3:49 PM

Hi
u can do in this way in processRequest method
String Account_ID =(String) pageContext.getParameter("Account ID ");
OAMessageLOVInputBean mtiBean = (OAMessageTextInputBean)table.findIndexedChildRecursive("LovField_ID");
mtiBean.setText( pageContext,Account_ID );
Thanx

How to execute a method after page Load?

My question is very similar to what was discussed in following thread:
How to execute a method after page Load?
My requirement is that I want to run a method in backing bean of a page, immediately after the page gets loaded. In that method I want to invoke one of the method action included in the pagedef of this page, conditionally.
I tried using the approach given in the above thread, i.e to use <f:view afterPhase="#{backing_security.setPermPriv}">, but the problem is that our page is not using 'f:view' , so I explicitly added one f:view with afterPhase property set , but it is not working, page it self is not getting loaded, it is throwing the error:
Root cause of ServletException.
java.lang.IllegalStateException: <f:view> was not present on this page; tag [email protected]e8encountered without an <f:view> being processed.

Hi,
I assume that your view is a page fragment and here - indeed - the f:view tag cannot be used. If you use ADF then one option would be to use a custom RegionController on the binding layer to listen for the render phase to invoke the method. Another option would be to use a hidden field (output text set to display="false" and have this component value referencing a managed bean property. The managed bean property's getter method can now be used to invoke the method you want to run upon view rendering

Execute search programatically during initial page load.

hi,
when the page is initially rendered, i have requirement to have the page automatically retrieve rows that belong to the user (ie execute a search programatically)
to achieve that i did the following -
1. created search page using autocustomizationcriteria
2. mapped all search fields to corresponding VO fields ( i intend to not override the default where clause since all my search can directly be mapped to a VO attribute)
3.populated the userlogin value into the corresponding search field as follows -
String lg = pageContext.getUserName();
OAMessageLovInputBean lovBean = (OAMessageLovInputBean)webBean.findChildRecursive("searchLogin"); //the searchfield is a messageLOVInput
lovBean.setValue(pageContext, lg);
the behavior i was expecting is for the page to automatically generate the where clause since i populated the search field that is mapped to the VO attribute and execute the query (i did not invoke executequery() per dev guide) BUT instead it is executing a BLIND query with no where clause.
would appreciate any insight into what i am doing wrong....
thank you.

hi, i had initially done the setting of the whereclause and executing programatically. however, when you do that, subsequently, the 'Go' button also needs to be handled programatically (including all search criteria whereclause generation) and then you loose all the features of the queryBean especially the different search options (eg like , starts with etc) on the Advanced Panel unless you code for all those features yourself...... NOTE - the need to handle the 'Go' button yourself happens even though after executeQuery() for just the initial page load, i reset the whereclause and whereclauseparams to NULL....
i also do not have a formvalue associated with the searchlogin field.
any other inputs please ?
thank you.

Execute code on UI component during page load

Hi All,
I am usng Jdeveloper 11gR2.
I want to invoke below code snippet to change the properties of input text fields and set them to enable on page load -
 FacesContext facesContext = FacesContext.getCurrentInstance();
 UIViewRoot root = facesContext.getViewRoot();
 RichPanelFormLayout formClass = (RichPanelFormLayout)root.findComponent("id");
 List<UIComponent> uiComponentList = formClass.getChildren();
 for (UIComponent uiComponent : uiComponentList) {
 if (uiComponent instanceof RichInputText) {
 //((RichInputText)uiComponent).setDisabled(true);
 ((RichInputText)uiComponent).setColumns(100);
 Boolean flag = ((RichInputText)uiComponent).isChanged();
 System.out.println("flag - " + flag);
At present the code snippets works well on command component action but I want to execute the same during initial page load without the use of any command component.
Please advise on how to achieve this.

Single page application and page load time

I'm trying to instrument a "single page application" with Application Insights but it seems that there is not way to provide manually the performance data (page load time) when invoking the logPageView() method.
The single page application has a "unique page" and all views are displayed using internal routing feature without refreshing the main page once it is loaded. So the logPageView() method is invoked multiple times: one of each displayed view.
It means that the built-in performance counter (netCon, ..., ptotal) based on window.performance.timing.* do not make sense for this type of application, that should be based on manual computation of the time needed to render each view.
Is there any method to provide manually this information using logPageView() or separate method ? If not, is there any idea to fully support in the future the single page application ?
Thanks in advance,
Maurizio

Hello Maurizio,
Do you still have the same issue with the latest
AI in Azure Portal?
There should be new API layer with the ability to submit custom properties and metrics. This might work well for you scenario. AI nugets are still in preview, please, use "Show Prerelease" in VS when adding those.

Method called at page load time of jspx page

I am using the jdeveloper11.1.1.1.0 version.
is there any method that is called at page load time. in this method i need to apply the set where clause on view object and some more functionality i need to add here.in ADf life cycle , is there any method like init() ?

you would have implement PagePhaseListener and extend this from your backing bean class..
package view.controller;
import oracle.adf.controller.v2.context.PageLifecycleContext;
import oracle.adf.controller.v2.lifecycle.Lifecycle;
import oracle.adf.controller.v2.lifecycle.PagePhaseEvent;
import oracle.adf.controller.v2.lifecycle.PagePhaseListener;
import oracle.adf.model.binding.DCBindingContainer;
import oracle.adf.model.binding.DCIteratorBinding;
import oracle.binding.BindingContainer;
public class CustomPagePhaseListener implements PagePhaseListener {
 * Before the ADF page lifecycle's prepareModel phase, invoke a
 * custom onPageLoad() method. Subclasses override the onPageLoad()
 * to do something interesting during the
 * @param event
 public void beforePhase(PagePhaseEvent event) {
 PageLifecycleContext ctx = (PageLifecycleContext)event.getLifecycleContext();
 if (event.getPhaseId() == Lifecycle.PREPARE_MODEL_ID) {
 bc = ctx.getBindingContainer();
 onPageLoad();
 bc = null;
 * After the ADF page lifecycle's prepareRender phase, invoke a
 * custom onPagePreRender() method. Subclasses override the onPagePreRender()
 * to do something interesting during the
 * @param event
 public void afterPhase(PagePhaseEvent event) {
 PageLifecycleContext ctx = (PageLifecycleContext)event.getLifecycleContext();
 if (event.getPhaseId() == Lifecycle.PREPARE_RENDER_ID) {
 bc = ctx.getBindingContainer();
 onPagePreRender();
 bc = null;
 public void onPageLoad() {
 // Subclasses can override this.
 public void onPagePreRender() {
 // Subclasses can override this.
}add your backing bean class as controllerClass in the corressponding pageDef <pageDefinition....> tag.
ControllerClass="#{backingBeanScope.backing_YourBackingBean}"
in your backing bean add pageload method like below and put your code (this method being called when the page loads...)
public void onPageLoad() {

Calling a java script function while page loads in ebiz

Hi OAF gurus,
I have a requirement of Calling a java script function at each OAF page renders or Loads.
I.e. when any OAF page loads or render in Oracle e-biz i have a java script function which needs to be called Is there any way to implement the above mentioned requirement.
Many thanks in advance..
Sourav

Hi!
From OAF classes java doc:
oracle.apps.fnd.framework.webui.OAPageBean
A class for processing and rendering HTML pages, designed to be invoked from either a JSP page or a servlet.
Allows you to:
Validate a user's session and redirect to a login page.
Set the servlet Response content type to the correct character set as defined by the ICX_CLIENT_IANA_ENCODING profile. (The character set should NOT be set in the JSP page ContentType declaration.)
Parse a HTTP Request and initialize BC4J application modules and view objects. (For HTML post, apply the content of the submitted form parameters to view objects.)
Render a HTML page header and body
It has 2 metods:
public void renderDocument()
Renders the HTML document. This is the most common API invoked by JSPs or servlets, and is used to render both the HTML header and body.
renderBody
public void renderBody()
Renders the HTML body only.
I think you can decompile this class or get the source from oracle and add your javascript code into this method.
When OA page rendered, your code would be added to avery page, i think
But it's some kind of hack or something ;-)

Getting Page Load Error while opening a Opportunity in new window

Hi All,
outbound SSO is enabled.
when i try to punch-in to my application from CRM through opportunity web link with Web Link Target as "open in custom tab" its working properly, but when i have Web Link Target as "open in new window" i am getting page load error. previously with out Outbounf SSO it is working properly.
Do i need enable any settings in CRM
thanks

when the web link target is "open in new window" or "open in current window" the request send to third party application from CRM ONDemand is HTTPS request as SSL is not enabled it is giving "page load error"(In the web link we are specifying http only) (User athentication type is "username & password/ SSO")
Is there any setting in CRM Ondemand to send Http request only instead of HTTPS?

How can I get back into my application aftermath invoking Start up page of index.htm ?

Gorgeous Hello All,
If anyone of you can please provide me a solution for the following, will help me in plentious and galore.
Am using Adobe RoboHelp, Version 10 and IE version being 10.
A hurdle :-
I have a application which has been developed in ASP .NET, Version 4.0. Help link has been created in this application wherein here the Start up page of index.htm has been linked to be read from the RoboHelp local project folder\!SSL!\Multiscreen_HTML5\desktop. All are working absolutely fine except when
I login into the above-said application -> click on the Help page -> the index.htm opens with Contents, Index, Glossary -> Am able to successfully perform any task by respective clickings
-> But I am not able to get back into my application when I click on the IE provided Back button (Alt+Left) -> Any amount of invoking Back button makes the system getting looped into this Start up page of index.htm only -> When I Close Tab (Ctrl + W) or Close ( X ) -> The window session gets closed and I have to repeat all by relogin once again.
How can I get back into my application aftermath invoking Start up page of index.htm ?
(I can always get back into the application easily by erasing those parts in the url which refers to this RoboHelp linkages – but this certainly looks non-polished work)
Help Please

Hey Jeff, I used Internet Explorer 10.0.9200 and Google Chrome 26.0.1410. Alas - it is the same behavior.
(But Jeff : When I used Microsoft HTML Help as primary layout to generate chm file , My Help when launched from my Application opened in a new browser window and when I closed this Help browser window did not close my application. Looks like need to write few liner code to get this issue settled )
Thanks Indeed of lots for your concerns Jeff !!!

I want to writte C# code for 503 Service Unavailable error to web application page immediate close connection any page loaded

Here is a ticket regarding our current client web application ( Image data add, edit , delete in folder with form data in MSSQL Database) that using code c#, web form, ajax, VS2008, MSSQL Server2008 , it appears that there is an error where the HTTP
503 error occurs.
. Below is a conversation with Host Server support assistant.Can you take a look at it?
Ben (support) - Hi
Customer - We're having an issue with our windows host
Ben (support) - What's the issue?
Customer - 503 errors
Ben (support) - I am not getting any 503 errors on your site, is there a specific url to duplicate the error?
Customer - no, it comes and goes without any change Customer - could you have access to any logs ?
Ben (support) - Error logs are only available on Linux shared hosting, however with this error it may be related to you reaching your concurrent connections
Ben (support) - You can review more about this at the link \
Customer - probably yes - how can we troubleshoot ?
Ben (support) - http://support.godaddy.com/help/article/3206/how-many-visitors-can-view-my-site-at-once
Ben (support) - This is something you need to review your code and databases to make sure they are closing the connections in a timely manner
Customer - we're low traffic, this is an image DB to show our product details to our customers
Customer - ahhhh, so we could have straying sessions ?
Ben (support) - Correct Customer - any way you could check if it's the case ?
Customer - because it was working previously
Ben (support) - We already know that's the case as you stated the 503 errors don't happen all the time if it were issue on the server the the 503 would stay.
Customer - so our 2/3 max concurrent users can max out the 200 sessions
Customer - correct ?
Customer - is there a timeout ?
Ben (support) - no that's not a time out concurrent connections are a little different then sessions and or connections. Lets say for an example you have 5 images on your site and 5 7 users come to your site this is not 7 concurrent connections but 35. They
do close after awhile hence why the 503 error comes and goes. You can have these connections close sooner using code but this is something you have to research using your favorite search engine
Customer - thank you so much
Customer - I'm surprised that this just started a few weeks ago when we haven't changed anything for months
Customer - any changes from your side ? lowering of the value maybe ?
Customer - I'm trying to understand what I can report as a significant change
Ben (support) - We haven't touched that limit in years
Ben (support) - This could just be more users to your site than normal or even more images
Customer - I was thinking that could be it indeed
Customer - so I need to research how to quickly close connections when not needed
Ben (support) - Correctly
Ben (support) - correct
Customer - thanks !!
Ben (support) - Your welcome
Analysis :
The link provided tells us : All Plesk accounts are limited to 200 simultaneous visitors.
From what Ben (support) says and a little extra research, if those aren't visitors but connections then it's quite easy to max out, especially if the connections aren't closed when finished using. I'd suggest forwarding this to Kasem to see what he thinks.
Cheers,
Customer

Hi Md,
Thank you for posting in the MSDN forum.

To help you find the correct forum, would you mind letting us know more information about this issue? Which kind of web app you develop using C# language? Is it an ASP.NET Web Application?
If yes, I suggest you could post the issue directly on

After updating to the latest version of Firefox on my Mac there is no progress bar for the page load. I really miss this feature and can't seem to find a way to obtain it.

The page load progress bar that was on the lower right of the window is no longer there. After updating to the latest version of Firefox on my Mac there is no progress bar for the page load. I really miss this feature and can't seem to find a way to obtain it. The tab has a circular progress wheel but this is useless for determining a stuck or slow loading page.
PLEASE NOTE: I am typing this in from a Windows based work computer but am asking about my Apple MacBook Pro that i use at home.

Firefox 4 saves the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session. 
You can use "Firefox > History > Restore Previous Session" to get the previous session at any time. 
There is also a "Restore Previous Session" button on the default about:home Home page. 
Another possibility is to use:
