When a page is visited simultaneously

If a page is visited by many users simultaneously then how many trees of that page are created at server ? If as many trees are created as the number of users then is it not a burden to server which is a disadvantage ?

anyone knows how to invoke a jsf logic onpage load w/o doing anything?
In servlet, we can just use goGet or doPost to execute some tasks as user sends a request through url...
how do i do this in jsf..?

How do I prevent the last page I visited reopening when I launch safari?

How do I prevent the last web page I visited reopening when I launch safari?

Is there a way to find exactly when a certain web page was visited? I know if I go to Tools/Page Info, I can see how many times that page was visited, but I would like to know if I can find the exact time and date. Thank you.

I am using Firefox version 3.6.13

You can find the last time a web page was visited by using the Library.
In the History menu select "Show All History" to open the Library. You can use the Library to view the history, and by default it will show the last date & time the site was visited. If the Visit Date column is not visible, within the Library select Views, then Show Columns, then Visit date to display that column.

Disclosing first tab (in a panel tab) always when a page loads up

Hi,
I am using JDeveloper 11.1.1.4 and I have a page which contains panle tab. I have configured MDS in my application. So if I close the page visiting 2nd tab, the next time if I visit the page, it opens up with the 2nd tab disclosed.
What I want is to disclose the first tab when the page loads up. Can I exclude this page from MDS or Is there any preferred way of doing this in ADF?

Hi Sudipto,
Thanks for your reply. Do you mean to say that I need a taskflow to achieve this? The reason why I am asking this is because my page is a simple page which comes under unbounded taskflow of adfc-config.xml.
Is there any other approach in achieving this?
Regards,

Firefox 4 doesn't open in a homepage, but rather opens the last page I visited, which I HATE!!!!!!!!!!!!!!!!!!

So far the Firefox upgrades are nothing but trouble to me and my computer. Where is the homepage. Why when I open Firefox from the desktop shortcut do I not get a homepage, but rather the last page I visited. I was doing bills, and finished but couldn't find the log off button, so closed the page, and then closed firefox. When I re-opened, it opened right to the page where I was still signed into my account!!!!!!! A security failure if I ever saw one. There is not one thing I have found to be helpful since Firefox first updated me to 3.6.14, then quit responding completely! So I tried the 4 Beta, and it is so far a disaster.

If the Cookies window is open and no browser or other Firefox windows are open, opening a new browser window will now still open the last page visited instead of a blank page, even if "Show a blank page" is selected for "When Firefox starts:", and even if the last browser window opened was blank; I tested this by opening a webpage and then opening a blank browser window, closing the browser window with the webpage, then closing the blank browser window, then opening a new browser window while the Cookies window remained open. It is a time waster to have to continually close and reopen the Cookies window and a potential privacy disaster to have your website reopened after you closed your browser. Please, please, fix this.

ORA-06502 on "Help Text" region when changing pages on a tabular form

Hello everybody,
We are developing an application on Apex 4.1.0.00.32. This application have some pages with tabular forms and these pages uses a page zero as template. In this page zero, we have added two sidebar regions: a list region to navigate on the application and a help text to describe how to use our application.
The problem occurs when the tabular split the records into pages (since it has more records that it can show on a single page). When the user clicks to change to another page, Apex raises an ORA-06502: PL/SQL: numeric or value error as described below:
Erro ao renderizar a região "Ajuda". ORA-06502: PL/SQL: erro: erro de conversão de caractere em número numérico ou de valor

Obs: Our database is in Brazilian Portuguese, so I guess it will be hard for some people to understand the first two lines! :)
We have tried to change the pagination style of the tabular form and change the region model of the help text but the problem still happens.
Does anyone an ideia about what this may be?
Thanks in advance!

I am getting the exact same message, to the line number, also in APEX 4.1.0.0.32.

How do I stop a query from running when the page is loaded

Hi All,
I'm using JDeveloper 10.1.3.4. I have a JSPX page that is used to collect search parameters and then when a button is clicked uses those values to run a query and then populate a table on the same page. The problem is that when the page is loaded the system attempts to run the query. The query is a method in a session bean. I can keep the method from running the query code by wrapping it in an 'if' statement and checking the parameters for null (or other value). Once the parameters are collected the query is invoked but it looks like the method is running twice, once with the parameters (here I've checked that the result actually has rows in the list) and then again where the parameters are null and the method returns null.
What is the best way to do what I want here? From the buttons action method I am called the session beam method and returning null to stay on the same page. I think that is why the method is running the second time and returning null.
TIA,
Dave

High Virtual memory usage when using Pages 2.0.2

Hey there,
I was just wondering whether there had been any other reports of unusually high memory usage when using Pages 2.0.2, specifically Virtual memory. I am running iWork 06 on the Mac listed below and Pages has been running really slowly recently. I checked the Activity Monitor and Pages is using hardly any Physical memory but loads of Virtual memory (so much so that the Page outs are almost as high as the Page ins (roughly 51500 page ins / 51000 page outs).
Any known problems, solutions or comments for this problem? Thanks in advance

I don't know if this is specifically what you're seeing, but all Cocoa applications, such as Pages, have an effectively infinite Undo. If you have any document that you've been working on for a long time without closing, that could be responsible for a large amount of memory usage.
While it's good practice to save on a regular basis, if you're making large amounts of changes it's also a good idea to close and reopen your document every once in awhile, simply to clear the undo. I've heard of some people seeing sluggish behavior after working on a document for several days, which cleared up when the document was closed and reopened.

How do I invoke an ActionListener on a page when the page initially loads?

How do I invoke an ActionListener on a page when the page initially loads?
Page 1: A user clicks on a h:commandButton and is navigated to Page 2.
Page 2: When the page loads and goes through RESTORE_VIEW, APPLY_REQUESTS and RENDER_RESPONSE, I need to call an ActionListener in the managed bean for Page 2.
However, if the user comes in from any other page than Page 1, the ActionListener cannot be invoked intially when the page loads. The user has a choice to click on the h:commandButton on Page2 to invoke the ActionListener.
What is an example of invoking a method with the ActionListener signature in Java code?
Where would I put the code to invoke the ActionListener, in a beforePhase or afterPhase, constructor?
Thanks,
--Todd

Interesting. You're right. It doesn't happen when I click away from this site and then return. Maybe I'm barking up the wrong tree. Maybe it's the specific website I was thinking of and not Firefox. Unfortunately, I have to use that site all the time for work. I'll try contacting their webmaster. Thanks for your help.

Now that the "Status Bar" is gone, is there a way to hide the "status notification" (bottom left corner) when a page loads? This is on Windows & FF5/6

The so called "Status Bar" has apparently gone away since FF4, I'm now onto 6 I think, on my work machine. But one of the things I liked about the Status Bar was that it could be hidden entirely.
With no Status Bar, now when a page is loaded in FF, you get a floating "Status Notification" in the bottom left corner for a second or two while the page is loading (this even happens in FullScreen F11, something I never had to deal with when the Status Bar existed).
What I want to know is, is there a way to turn off this "Status Notification" entirely? A setting somewhere? Something in About:config? I haven't been able to find anything.

1. Install the addon Status 4 evar, which puts the status text back in the status bar: https://addons.mozilla.org/en-US/firefox/addon/status-4-evar/
2. Hide the status bar by right clicking the refresh button and unchecking "Addon bar"

Help using app_standard.event(when-tab-page-changed')

Hello ,
I need to create a form with the following requirements . There is one content canvas which contains a tabbed canvas and on this there are two stacked canvases .
The problem is that when I compile my form and ftp to oebs , I cannot view the tab pages on the canvas .
I see only my the fields displayed in the first tab page without the 'tab pages'.
How do I solve this issue please ?
My when-page-page-trigger contains the following :
BEGIN
APP_STANDARD.EVENT('WHEN-TAB-PAGE-CHANGED');
if name_in('system.cursor_block') = 'XX_ERROR_MANAGEMENT' then
if not form_success then
-- Revert tab to prior value and exit
set_canvas_property('CAN_INT',topmost_tab_page,name_in('system.tab_previous_page'));
return;
end if;
-- Move to first item on each tab
if target_canvas_name = 'CAN_INT' then
SHOW_VIEW('CAN_ONG1');
go_item('XX_ERROR_MANAGEMENT.INTERFACE_TYPE');
else
show_view(target_canvas_name);
end if;
END IF;
END;
Any help will be much appreciated . Thanks .

DO NOT USE PREVIEW TO FILL OUT PDF FORMS, IT WILL DESTROY PDF FILES. Sorry, but I had to shout here to prevent damage to your PDF files.
Here is one of the symptoms when you fill out a PDF form with Preview: If you save it and return it to the author, they will not be able to see the text that you've added to form fields - unless they click on a field, which will reveal the contents of just that field. You can recover from this problem, but Preview will also remove other field types, and will actually rewrite your complete PDF while ignoring what it does not understand. Take a look at this blog post for more information about the damage that Preview will cause: Preview.app - Killer of PDF Files

ADF how can i execute a query with parameters when the page renders

hi
i am using ADF web 11g
i need to execute a query with parameters when the page renders
thanks

hello,
I'm a fan of Java code, I really am.
But when you use ADF, you decided to move to a more declarative environment.
So why not do it declarative, the adf way?
In your pagedef insert a action binding.
This can be anything, a call to the application module, a call on the iterator(Like executeWithparams, etc.)
Create an invokeAction in your pagedef and set the condition.
This example refreshes(Action 2 is execute query) the data.
First the method binding:
 <action IterBinding="PersoonIterator" id="Execute" InstanceName="LSAppModuleDataControl.Persoon"
 DataControl="LSAppModuleDataControl" RequiresUpdateModel="true" Action="2"/>And the invoke action
 <invokeAction Binds="Execute" id="refreshData"/>This always refreshes the data on page entry, but anything is possible, you can set condictions for the invokeAction.
-Anton
PS Yes I know that pagedefs become backing beans in the end and yes that is Java code, but if you wanna play the ADF way, the goal is the reduction of Java code and the increased performance of declarative programming.
