Event Handling of pages
I want to display pages that are not connected to the
application. The application is to activate a page then allow for a
return. If I put the pages into a Viewstack or TabNavigator I have
no problems getting to the page. Its not what I want but. If I use
Module loader I can get to the page but can got back,
What do you mean by these terms?:
"page"
"display"
"connected to"
"activate"
"return"
"put"
"get to"
"get back"

Input value given on web page is not getting pickedup in event handler
Hi friends,
I have created one simple page in SE80 with program with flow logic option, in which I would like to show business partner details from BUT000 table with the input of partner number. But the thing is the input value(partner no.)which I am giving on web page is not getting picked up in selection in event handler though I am giving input value it is becoming initial while selecting. What could be the reason?
Below I am mentioning the code which I have written in even handler for OnInputProcessing event.
CASE EVENT_ID.
WHEN 'select'.
NAVIGATION->SET_PARAMETER( 'partner' ).
SELECT * FROM but000 INTO TABLE I_but000 WHERE partner BETWEEN partner AND partner1.
WHEN OTHERS.
ENDCASE.
Thanks in advance,
SteveHi Abhinav,
I tried with the one you posted. But it is giving run time error as shown below.
Note
The following error text was processed in the system CRD : Access via 'NULL' object reference not possible.
The error occurred on the application server crmdev_CRD_00 and in the work process 0 .
The termination type was: RABAX_STATE

Event handler when using partial page refresh ?
Hi
I have a calendar, which uses partial page refresh. The problem is how to make javascript wait until the calendar has loaded and then do some updates on the calendar (after the user has pressed the next button that runs apex.widget.calendar.ajax_calendar('S','next');, for example ). I thought I could add "onreadystatechange" (or onload) event handler to the calendar like this: onreadystatechange="checkState()", where the function would check the state and if ready then do the updates. This doesn't work. Could somebody please tell me why not ?
TiinaHi,
It seems that ajax calendar missing event apexafterrefresh.
I do not know is this "bug" or just feature.
That event would be useful to your case , if I understand correct what you looking for.
For workaround , you can over write original function by placing this to calendar region footer
<script>
apex.widget.calendar.ajax_calendar=function(p_calendar_type, p_calendar_action, p_calendar_date, p_calendar_end_date){
var l_cal_type_field = $v('p_cal_type_field_id');
var l_cal_date_field = $v('p_cal_date_field_id');
var l_cal_end_date_field = $v('p_cal_end_date_field_id');
var l_cal_id = $v('p_calendar_id');
var l_calendar_region = 'calendar' + l_cal_id;
if ( p_calendar_type != 'C' ){
$s(l_cal_date_field,$v('p_calendar_date'));
}else{
if ( $v(l_cal_date_field) == '' ) {
$s(l_cal_date_field,$v('p_calendar_date'));
if ( $v(l_cal_end_date_field) == '' ) {
$s(l_cal_end_date_field,$v('p_calendar_end_date'));
// create and apex.ajax.widget object
var a = new apex.ajax.widget('calendar',function(){
/* start the return function */
if(p.readyState == 1){
document.body.style.cursor = "wait";
}else if(p.readyState == 2){
}else if(p.readyState == 3){
}else if(p.readyState == 4){
$x(l_calendar_region).innerHTML = p.responseText ;
$s(l_cal_date_field,$v('p_calendar_date'));
if (p_calendar_type == 'C') $s(l_cal_end_date_field,$v('p_calendar_end_date'));
document.body.style.cursor = "";
/* DO HERE THINGS AFTER CALENDAR REFRESH */
}else{return false;}
// code for next,previous and today
if (p_calendar_type == 'S'){
p_calendar_type = $v('p_calendar_type');
}else{
$s(l_cal_type_field,p_calendar_type);
a.ajax.addParam('p_widget_mod',p_calendar_type);
a.ajax.addParam('p_widget_action',p_calendar_action);
a.ajax.addParam('x01',l_cal_id);
var lDate = (!!p_calendar_date && p_calendar_date !== '')?p_calendar_date:$v(l_cal_date_field);
if (p_calendar_type == 'C') {
var lendDate = (!!p_calendar_end_date && p_calendar_end_date !== '')?p_calendar_end_date:$v(l_cal_end_date_field);
a.ajax.add(l_cal_date_field,lDate);
if (p_calendar_type == 'C') a.ajax.add(l_cal_end_date_field,lendDate);
a.ajax.addParam('x02',lDate);
if (p_calendar_type == 'C') a.ajax.addParam('x05',lendDate);
a.ajax.add(l_cal_type_field,p_calendar_type);
a._get();
</script>Where I have comment *"do here things after calendar refresh"*, you can hook own scripts.
Of course this is not best way, but might help you till ajax calendar support dynamic actions fully

Using page attribute in event handler method of controller
Hi all,
I have created a page attribute GT_TABLE. I need to use this table in one of the event handler methods of the controller of the same page. I tried to use the GET_ATTRIBUTE method but it always returns an empty table.
Can someone please guide me in this respect.
Thanking you in advance,
Regards,
Sumit.Hi Sumit,
The page attribute you mention (GT_TABLE) it's an internal table, isn't it? So far I know, the value of internal table will gone when BSP finish to load in server. If you want to keep the data in internal table, you need to load the internal table into Session (in one of page event in BSP).

Java Event Handling in JSP Pages
Dear All:
This is what I wanna do. when user enters text in my <input type="text" ... > in my JSP page, I want to take this user entered data and convert it in another language simultaneously as the user is inputting text in another textarea.
Right now the only choice I have is onChange="convert()" Javascript function.
But I dont want to use Javascript as I already have a Java class which does that for the Swing GUI client.
Is their a way i can embed java for event handling in jsp.
thanks,
Chetanonly if you use an applet, javascript, etc.
remember, jsp is server-side, not client-side
what the client sees is html or whatever (i.e. static content) -
How can I execute an external program from within a button's event handler?
I am using Tomcat ApacheTomcat 6.0.16 with Netbeans 6.1 (with the latest JDK/J2EE)
I need to execute external programs from an event handler for a button on a JSF page (the program is compiled, and extremely fast compared both to plain java and especially stored procedures written in SQL).
I tried what I'd do in a standalone program (as shown in the appended code), but it didn't work. Instead I received text saying the program couldn't be found. This error message comes even if I try the Windows command "dir". I thought with 'dir' I'd at least get the contents of the current working directory. :-(
I can probably get by with cgi on Apache's httpd server (or, I understand tomcat supports cgi, but I have yet to get that to work either), but whatever I do I need to be able to do it from within the button's event handler. And if I resort to cgi, I must be able to maintain session jumping from one server to the other and back.
So, then, how can I do this?
Thanks
Ted
NB: The programs that I need to run do NOT take input from the user. Rather, my code in the web application processes user selections from selection controls, and a couple field controls, sanitizes the inoputs and places clean, safe data in a MySQL database, and then the external program I need to run gets safe data from the database, does some heavy duty number crunching, and puts the output data into the database. They are well insulated from mischeif.
NB: In the following array_function_test.pl was placed in the same folder as the web application's jsp pages, (and I'd tried WEB-INF - with the same result), and I DID see the file in the application's war file.
try {
java.lang.ProcessBuilder pn = new java.lang.ProcessBuilder("array_function_test.pl");
//pn.directory(new java.io.File("K:\\work"));
java.lang.Process pr = pn.start();
java.io.BufferedInputStream bis = (java.io.BufferedInputStream)pr.getInputStream();
String tmp = new String("");
byte b[] = new byte[1000];
int i = 0;
while (i != -1) {
bis.read(b);
tmp += new String(b);
getSelectionsDisplayTextArea().setText(getSelectionsDisplayTextArea().getText() + "\n\n" + tmp);
} catch (java.io.IOException ex) {
getSelectionsDisplayTextArea().setText(getSelectionsDisplayTextArea().getText() + "\n\n" + ex.getMessage());
}Hi Fonsi!
One way to execute an external program is to use the System Exec.vi. You find it in the functions pallet under Communication.

Dropdown box - which event handler to use ?
I am having trouble with setting the readonly property (via Javascript) of the adjacent textbox to my dropdown box when the index value is a certain number.
I tried using MouseUp, MouseDown, and even OnBlur....but the readonly does not seem to be getting set to true or false consistently.
Could this be a timing issue ? The textbox that I am trying to control is the next tab-order control in the list of controls for this page.
This same logic is working fine in the MouseUp event handler for check boxes. So I am just wondering if this is a bug or must my implementation change to accomodate dropdown boxes ? For instance, should I move the logic to the Enter event handler of the textbox instead ? Can a control's own eventhandler set itself to readonly when it is the active form field ?After tons and tons of testing time, I've come to the conclusion that dropdowns are totally buggy in 11.0.07 release of Acrobat Pro.
Even if you set the "commit values immediately", you get the PRIOR selected item's value as the event value, not the CURRENT one.
This occurs in a Validate event handler script. I have not been able to use any other event handlers for a dropdown except the OnBlur....and then, for my purposes, IT'S TOO LATE !!!
This is totally worthless as I need to setFocus() and set fields to readonly based on the immediate dropdown offset or face value. -
Javascript embedded in button pl/sql event handler not being executed
Javascript calls not working from pl/sql button event handler. What am I missing? Are specific settings needed to execute javascript from pl/sql proceedures?
Example: Want to toggle target='_blank' off and on in a button pl/sql event handler to open url call in new window & then reset when processing submit is done & the app returns to the form.
portal form button's pl/sql submit handler:
begin
htp.p('<script language=JavaScript>') ;
htp.p('this.form.target="_blank"') ;
htp.p('</script>') ;
PORTAL.wwa_app_module.set_target('http://www.oracle.com') ;
htp.p('<script language=JavaScript>') ;
htp.p('this.form.target="_blank"') ;
htp.p('</script>') ;
end ;
Putting the following in the button's javascript on_click event handler works great:
this.form.target='_blank'
to force opening new window with a call in the button's submit pl/sql code via:
PORTAL.wwa_app_module.set_target('http://www.oracle.com') ;
but then the target='_blank' is left on when the submit is done & we return to the form.
putting the above javascript as a function (called fcn_newpage) elsewhere (e.g., after form opens) & calling in the submit pl/sql with
htp.p('fcn_newpage') ;
also doesn't work.
Metalink thought this was an application issue instead of a bug, so thought I'd see if anyone knows what's going wrong here. (Portal 9.0.4.1)thanks for your discussion of my post.
Please clarify:
"htp.p('fcn_newwindow') sends a string":
What would you suggest the proper syntax for a function fcn_newwindow() call from a pl/sql javascript block that differs from
htp.p('<script language="Javascript">') ;
htp.p('fcn_newwindow');
htp.p('</script>');
or more simply
htp.p('fcn_newwindow') ;
More generally, what I'm trying to figure out is under what conditions javascript is executed, if ever, in the pl/sql of a button (either the submit or custom event handler, depending on the button).
I've seen lots of posts asking how to do a simple htp.p('alert("THIS IS TROUBLE")') ; in a pl/sql event handler for a button on a form, but no description of how this can be done successfully.
In addition to alerts, in my case, I'd like to call a javascript fcn from a pl/sql event handle that would pass a URL (e.g., http://www.oracle.com) where the javascript fcn executed
window.open(URL). The API call to set_target(URL) in pl/sql has no ability to open in a new window, so calling that is inadequate to my needs and I must resort to javascript.
Its clear in the PL/SQL of a button, you can effect form components since p_session..set_target & p_session.get_target set or get the contents of form components.
So to see if javascript ever works, I tried to focus on something simple that only had to set what amounts to an enviromental variable when we returned to the form after a post. I chose to try to change the html value of TARGET from javascript in the PL/SQL button because it doesn't need to be implemented until we finish the post and return to the form.
So I focused on a hack, setting this.form.TARGET='_blank' in the on_click event handler that forced every subsequent URL call or refresh of the form to be a new window. I then wanted to turn off opening new windows once I'd opened the URL call in a new window by setting TARGET='' in the portal form. I can achieve what I want by coding this.form.TARGET='' in the javascript (on_focus, on_change, or on_mousedown, ...) of every form component that might refresh the form. However, that is a ridiculous hack when a simple htp.p('<script>') ; htp.p('this.form.target=""') ; htp.p('</script>') ; at the end of the button's pl/sql event handle should do the same thing reliably if javascript ever works in the pl/sql event handler.
If we didn't have access to form components through p_session calls, I'd assume it was a scope issue (what is available from the pl/sql event handler). But unless my syntax is just off, when, if ever, can javascript be used in a portal form's pl/sql event handler for a button?
if I code a javascript funtion in the forms' pl/sql before displaying form:
htp.p('<script language="JavaScript">') ;
htp.p('function fcn_new_window(URL)') ;
htp.p('window.open(URL)' ) ;
htp.p('</script>') ;
the function can be called from a button's on_click javascript event handler:
fcn_new_window('http://www.oracle.com')
but from the same button's pl/sql submit event handler this call doesn't work: htp.p('fcn_new_window("http://www.oracle.com")')
So my questions remain: Is there other syntax I need, or does javascript ever work properly from the pl/sql of a form button's event handler? If it doesn't work, isn't this a bug that should be fixed by Oracle?
I can probably figure out hacks to make things work the way I need, but executing javascript from pl/sql event handlers seems to be the expected way to affect portal html pages (forms, reports, ...) and it seems not to work as expected. I don't feel I should have to implement hacks for something as simple as calling a javascript function from pl/sql when almost every example I've found in metalink or the forums or Oracle Press's "portal bible" suggests using javascript from pl/sql via the utility htp.p() to effect web page components in portal.
My TAR on the subject, while still open, returned the result basically: "We can reproduce your situation. Everything looks okay to us, but we can't explain how to use javascript where you want or point you to any documentation that would solve your problem or expain why it should not work the way you want it to. We don't feel its a technical issue. Why don't you post the problem on the portal applications forum."
I'm hoping I'm just missing something fundamental and everything will work if I implement it a little differently. So if anyone sees my error, please let me know.
by the way, not sure this is germain, but in reference to your comment:
"redirections in pl/sql procedures give a peculiar result. in a pl/sql procedure, usually, portals give the last redirection statement and ignore anything else coming after it."
if I try to raise an alert:
htp.p('alert("you screwed up")');
return;
in a pl/sql event handler, it still doesn't raise the alert, even though its the last thing implemented in the event handler. But if I set the value of a text box using p_session..set_value_as_string() at the same spot, it correctly sets the text box value when I return to the form. -
View not copied or enhanced with wizard Error while creating Event Handler method in Z Component
Hello Friends,
In one Z Component (Custom Component), in one of the views, while creating event handler, it gave me error message that view not copied or enhanced with wizard.
I am aware that in Standard Component, if we want to create the event handler method then we need to first Enhance the Component and then we need to enhance the view.
But, in the Z Component (Custom Component), how to create event handler method in one of the views as while creating event handler method i am getting view not copied or enhanced with wizard error.Hi,
Add a method in views impl class with naming convention eh_on__* with htmt and html_ex parameters. I dont have have the system right now. Please check any existing event import export parameters.
Check out do handle event method in the same class.
Redefine that method. Call that event method in this handle method. See existing code for reference.
Attach that event to the button on click event in .htm page.

BSP extension "download" - event handling problem
Folks,
First of all, I apologize if the answer is already out there, but I spent quite some time to find the solution for my problem but finally gave up:
I implemented the Download extension from Brian's and Tom's book. Since I am using an MVC based app, I put the event handling in the DO_HANDLE_EVENT of a controller instead of the OnInputProcessing event of a page. Here's how my app is designed:
I have a main controller that has an execute button to trigger a data selection based on some selection criteria. The result of this selection is displayed by means of a subcontroller with tableviews that are wrapped into my zdownload extension. Everything works fine: I make my selections, execute the app through the button of the main controller and get my result shown in the tableviews. I push the download icon, select my file format (XLS, HTML etc), get the dialog to choose whether to download or to display the file, perfect!
But now after I processed the download successfully - if I click the execute button in the main controller again, I still get the download dialog. It looks like the created event for the download does not get cleared. As I mentioned, I searched through SDN, but all I found were referrals to the call of DISPATCH_INPUT( ) in DO_REQUEST of the main controller, but unfortunately this one is already implemented.
Any ideas?
Thanks,
GuentherThere is an attribute of the download extension called display_url. You pass a value to the extension telling it what cached URL contains the binary content for your download. if this display_url attribute has a value assigned to it, then the element will render an iFrame to call the URl. However if the display_url attribute is empty, it won't render the iFrame. I suspect that you have a stateful application and after your download event you aren't clearing whatever field that you pass into the display_url attribute.

Hi There,
We have a use-case where we need intercept the event of af:inputComboboxListOfValues component.
I have table, which has three columns, Name, Description and Label.
I have a LOV on Name column.
When user change the value of Name column by selecting an value from dropdown, I need to do business validation, I show user the "Yes/No" popup with warning message, and base on the user's choice, either proceed with the change or stop the change.
My problem is that I am unable to find a appropriate event to show the popup.
I know there are several events in the af:inputComboboxListOfValues component, launchPopupEvent, returnPopupEvent and valueChangeEvent.
1. If I show popup on launchPopupEvent, after the user click "Yes/No" button on the popup, the page will be refreshed and dropdwon doesn't show the item list.
2. returnPopupEvent and valueChangeEvent event will be handled by framework in one request, there is no chance for user's interaction.
I am not familiar with ADF event handling machenism, can anyone help me?
Thanks in advance.

Edited by: 984466 on 2013-3-8 上午12:51Hi,
first of all, never post questions regarding internal JDeveloper builds (11.1.1.7 is not released to public) on this public forum. You are from Oracle and therefore have internal channels for this (note that using internal builds the problem could be with the build and not necessarily the code alone).
To your question:
I don't understand why
+"2. returnPopupEvent and valueChangeEvent event will be handled by framework in one request, there is no chance for user's interaction."+
doesn't work. If you set the "name" column component to autosubmit="true" then the listener fires as soon as you move out of the field and you can raise the alert. The current row in the binding points to the row you changed the name for and as such the value can be unset (the value change listener shows you the before and after value)

Event Handling in OADialogPage
Hi,
I have a scenario for my project.
where user should get a alert message with Ok(Proceed) and Cancel Buttons, when the budget for ticket is insufficient. After the alert, if user clicks on "Proceed", then it should navigate to confirmation page. If user clicks on Cancel, it should navigate to previous page.
For this I have used OADialogPage and belows follow my code. But When click on "Proceed", its not going to Proceed event handling.
Please help me out, its very important to finish this work as soon as possible.
