Is event handling possible with any object?

can i set a event notification to any object? say for example if i have a multidimensional array of strings can i associate a event handler with it so that when a different application or part of a code changes it's contents i can fire a method?
consider the scenario
initially...
String userId[][]=new String[R][C];
public MyServer()
        userId[0][0] = "mr00047";
        userId[0][1] = "false";
        userId[1][0] = "dider7";
        userId[1][1] = "false";
        userId[2][0] = "thegreendove";
        userId[2][1] = "false";
}now at some point the content of the userId array changes
for(int i=0;i<3;i++)
                if(temp.equals(MyServer.userId[0]))
flag=true;
MyServer.userId[i][1]="true"; // I want to fire a method from this point
break;
can any body tell me how can i do it? please help!!!

Event Handling Techniques with MVC

Hello all,
I have a situation where I have a model that can be thought of like a graph with many nodes and edges. I would like to create a view of this model with a customized JLabel that shows a data value for each node and edge in the model. The event handling to accomplish this has left me a bit perplexed, though. On one hand I was considering something similar to the following:
// a dedicated listener for each label
MyLabel mylabels[] = new MyLabel[numLabels];
for(int i = 0; i != mylabels.length; i++){
MyEventHandler eh = new MyEventHandler(mylabels);
mylabel.addMouseListener(eh);
public class MyEventHandler extends MouseAdapter{
private MyLabel label;
public void mouseClicked(MouseEvent e){
label.setText(etc...);
// at this point I would want to set the value of the point or edge
// that this label corresponds to, not sure of the best strategy
// here either
etc...
The other technique that I am considering might look similar to the following:
// only one listener for all labels
MyLabel mylabels[] = new MyLabel[numLabels];
MyEventHandler eh = new MyEventHandler();
for(int i = 0; i != mylabels.length; i++){
mylabel.addMouseListener(eh);
public class MyEventHandler extends MouseAdapter{
public void mouseClicked(MouseEvent e){
//call a control object in MVC architecture, for more processing
control.update(e.getSource(), (String)input);
etc...
// in the control object class
public void update(Object eventSource, String input){
MyLabel source = (MyLabel)eventSource;
source.setText(input);
// the label would have some kind of index to indicate which one it is
model.setData(source.getIndex(), input);
I am interested in knowing any accepted/popular solutions to situations like this. Are either of my samples worth implementing? I would greatly appreciate any suggestions. Thanks.

I would recommend creating a single listener and add it to every label added to the graph. If you're interested in events that occur outside of the labels (in the background), add a listener to the container of the labels as well.
Unfortunately, you cannot simply add a listener to the container and get all the mouse events from the container's children because Swing's event dispatching system will only dispatch mouse events to a container if the click location was not within any of the container's children. This means that mouse listeners registered to a container will only receive mouse events within the container's background.

OIM 10g Event Handler : Integrated with User Groups.User Members

I have created custom event handler and integrated it with User Groups.User Members data object.
here is my code od event handler class:

Event handler - open with explorer issue

hi all,
I have developed an event handler (itemadded syncronuos) for a library. i need to populate title field
public override void ItemAdded(SPItemEventProperties properties)
base.ItemAdded(properties);
properties.ListItem["Title"] = "some value"
properties.ListItem.SystemUpdate();
I have deployed the same feature to 2 environments -> Dev Env, Test Env.
when I copy and paste a pdf file with "Open with explorer" in Dev Env it works fine.
when I do the same in Test Env i can't copy the file and i get this error:
Error 0x80070057: the parameter is incorrect.
I see this in my Event Viewer
The description for Event ID 14901 from source WebClient cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
Could you help me?
Thanks.

On your local machine you are as you on the server, are you try it on the test server or browsing the test environment from local machine and doing the copy from local machine. also i hope your event handler is not firing on all the list, just make
sure. You can try this in a different library..create a fresh library and see what happen without event handler.

Getting ORA-00932 with any object table

Hi, I'm new to Oracle and it's enormous community so I apologize in advance for posting
in the wrong place or for giving not enough information.
As I just said, I'm new to Oracle therefore I'm following the [introductory guide|http://www.mcs.csueastbay.edu/support/oracle/doc/10.2/appdev.102/b14260/adobjint.htm#sthref102] and trying the examples it gives one-by-one.
I used to use MySql in the past but now I need to use a more stable and scalable database that allows
the storage of objects.
I'm using Oracle 10.g XE on a GNU/Linux computer (Ubuntu 8.10)
Let's start with the question:
in the Example 1-6 the following code is given:
CREATE TYPE emp_person_typ AS OBJECT (
name     VARCHAR2(30),
manager REF emp_person_typ );
Type created.
CREATE TABLE emp_person_obj_table OF emp_person_typ;
Table created.
INSERT INTO emp_person_obj_table
SELECT emp_person_typ ('Bob Jones', REF(e))
    FROM emp_person_obj_table e
    WHERE e.name = 'John Smith';
1 row(s) inserted.Executing these queries return successfull messages.
But when I try to retrieve the records by using this query:
select * from emp_person_obj_table;or when accessing the "Data" tab of that table in the Object Browser"
I get this error:
(error report:)
ORA-00932: inconsistent datatypes: expected NUMBER got REF RESMAN.EMP_PERSON_TYPAll queries are executed in the Application Express (2.1.0.00.39) query runner.
I think I did everything in the right manner, although the code is just copy-pasted from the guide, so I can't realize
why this annoying error is still appearing when accessing that table.
I noticed that executing the same selection query as above in the SQL*Plus CLI works as expected
and returns a resultset.
Thanks in advance for any reply.

Since the query works in SQL*Plus, I would tend to assume that this is a limitation of the APEX query runner. If you post over in the APEX forum, someone may be able to confirm that or suggest a way of working around it.
Do you need to use the APEX query runner? Could you use SQL*Plus or SQL Developer instead?

I just happen to know of a guy (through the net only) that dedicated a web site to fractal and software for creating fractals. Or I should say dedicated to mathmatical graphics.
The site hasn't done anything in quite a while but as far as i know all the links are still good.

Event Handling problem

Hello everyone.
i am trying to handle events in the item master date form (150) in order to hide the Item Cost. It is working fine with most of the time using only the UI api. However if doing the following actions, the events are not processed by the application anymore.
1- Start SBO (2005 sp1 pl18)
2- Login
3- Start my add-on with vb.net
4- Go into the item master data.. (handling events correctly)
5- Close item master data.
6 -Go into another form
7- Close the other form
8- Go back into item master data --> no events handling is done
Any ideas???
Thank you
Simon

Hi, Simon!
Try setting filters like that:
oFilter = oFilters.Add(SAPbouiCOM.BoEventTypes.et_FORM_ACTIVATE)
'// assign the form type on which the event would be processed
oFilter.AddEx("150")
oFilter = oFilters.Add(SAPbouiCOM.BoEventTypes.et_ITEM_PRESSED)
'// assign the form type on which the event would be processed
oFilter.AddEx("150")
oFilter = oFilters.Add(SAPbouiCOM.BoEventTypes.et_MENU_CLICK)
'// assign the form type on which the event would be processed
oFilter.AddEx("150")
I suppose that the setting method you used, was filtering only et_MENU_CLICK for the 150-form. But other events (et_FORM_ACTIVATE, et_ITEM_PRESSED) were handling for all forms...

Event Callback VI with LVOOP / overhead, caveats, future

OK another exploratory post from me. To anyone who has put up with this kind of thing from yours truly many times in the past, apologies. Completely impervious to any objections, here goes:
I have discovered a new toy : Registering event callback VIs. OK, I have used them before but a previous post by James McNally about his MVC framework revealed to me a usage which I had not previously thought of. Thanks for that James.
I like LVOOP. One pattern which is quite easy to understand is the command pattern in conjunction with state machines where we essentially replace the individual states of a state machine with external VIs. This makes it far easier to customise behaviour and allows for re-use of the core state machine for differing functionalities. Cool.
We can leverage this with LVOOP by passing different "commands" to the state machine depending on the real object being utilised and thus we have a nice extensible architecture. Again, cool. If we need to change one common action, we simply update that VI and instantaneously all ancestors share the new code in that command object. Double cool.
Problem is that I love User Events. The idea of having an extensible object model gets awkward to handle when you start using Events to handle communications in and out of the object. Create a Parent, Implement the 15 Events required. Create a child, Implement the 15 Parent events and the 12 new events. Create a Grandchild, Implement the 15 Grandparent, the 12 Parent and then the 25 new Events. Armageddon occurs when you want to change the common functionality for the sixth Event of the Parent. Now you need to go to each and every ancestor which uses them and update them. Wait a second, isn't LVOOP supposed to save me from this kind of crud? Frustration ensures. Can you ever be sure you got all instances? What about those obejcts not listed in the project, maybe you forgot one of them...... Nasty testing and debugging ensues.
I think I may have (partially) found the answer. What we need to do is basically do the same thing we have done with the command pattern and extract the individual frames of the event structure and place them into external VIs so that we can 1) re-use the VIs in each level of hierarchy and 2) maintain all the other niceties of Events.
Turns out that using Callback VIs for each level of the object hierarchy can help to solve this problem. You need to have a method with a different name for each level of the hierarchy which exposes the events int his way because each method will most likely have different input values.
Has anyone else done things like this? Are there limitations as to what can and can't be done with this arrangement? Any nasty bugbears waiting for me around the corner? How to deal with events which should give some kind of return value? Do I encorporate the return value into an implementation-agnostic return channel (again Events of course) with the object in question providing one return user event for each callback function which requires a return value?

Grr, I was trying to attach a file (whose contents apparently didn't match the file name?!!) when I ran out of time to edit and now I lost my text.
Here's an example.
Base class swaps out a control Caption for Label upon "Mouse Enter"
Child class swaps out a control Label for Caption on "Mouse Leave"
Grandchild increments a counter (stored in Description) for every "Mouse Enter"
Trivial but get's at what I mean.
I know I can do this in other ways but
1) I don't need a parallel process
2) I'm just having fun
Darn, I can't attach a zip. Rename this file to .zip and unpack. Sorry guys.

Event handling on a chart or a region

Hi All,
Is it possible to do event handling on a chart or on a region ? For instance I plotted a 2d chart if i click on any part of the chart i need to display some table. Is this event handling possible ?Do I need to write some code in java script ? Any pointers to this will be of great help
Thanks in Advance

Hello,
You can write js or use standard apex functionality.
Check this: http://tryapexnow.com/apex/f?p=2277:5
there is IR below first chart. You click, and the value of item P5_MONTH is populated, report below hows the corresponding month.
But you need to make it more sophisticated.
So basically using Apex url already gives lots
Change NULL to be a link to page 5 setting item P5_MONTH (sorry can not copy paste the whole query here, I get Sorry, content is not allowed)
IR SQl query:
select o.*
from demo_product_info p, demo_order_items oi, demo_orders o
where oi.product_id = p.product_id
and o.order_id = oi.order_id
and to_char(o.order_timestamp, 'RRRR MM') = :P5_MONTH

About CL_GUI_ALV_GRID's event-handling & PAI/PBO

Hi, all,
I met a problem when using CL_GUI_ALV_GRID's event-handling.
I created a simple event-handling-class with an event-handling-method for DOUBLE-CLICK event of CL_GUI_ALV_GRID. And the event-handling-method, only makes some changes to the contents of itab to be shown in ALV_GRID.
The problem is: In my idea, after event-dispatch and event-handling in PAI, subsequent PBO will be called. Since SET_TABLE_FOR_FIRST_DISPLAY is called in PBO, I would saw the changed itab shown. BUT, I saw the contents of the itab remaining unchanged.
* PAI module, DISPATCH the event
CASE OK_CODE.
    WHEN OTHERS.
      CALL METHOD cl_gui_cfw=>dispatch.
ENDCASE.
I debugged, and found that, after event-handling-method, PBO module doesn't execute.
That's my wondering, after the preceding PAI, shouldn't the subsequent PBO appear? OR is event-handling different from other user actions?
Many thanks.

Hi,
for double click you need explicit handler ,
just check it.

Help needed in implementing validation event handler in OIM 11g

Hello experts,
I am trying to set username policy by implementing a validation event handler in OIM 11.1.1.5.
Following are the steps followed
1. Import metadata
Created a file called Eventhandler.xml as below and imported using weblogicImportmetadata.sh
<?xml version='1.0' encoding='UTF-8'?>
<eventhandlers xmlns="http://www.oracle.com/schema/oim/platform/kernel" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.oracle.com/schema/oim/platform/kernel orchestration-handlers.xsd">
<validation-handler class="test.iam.eventhandlers.CustomValidationEventHandler" entity-type="User" operation="CREATE" name="CustomValidationEventHandler" order="1000" sync="TRUE"/>
</eventhandlers>
2. Register plugin
plugin.xml
<?xml version="1.0" encoding="UTF-8"?>
<oimplugins xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<plugins pluginpoint="oracle.iam.platform.kernel.spi.ValidationHandler">
<plugin pluginclass="test.iam.eventhandlers.CustomValidationEventHandler" version="1.0" name="CustomValidationEventHandler" />
</plugins>
</oimplugins>
Just givng sys out in the below code to check whther it is getting triggerred during user create.
package test.iam.eventhandlers;
import java.util.HashMap;
import oracle.iam.platform.Platform;
import oracle.iam.platform.context.ContextAware;
import oracle.iam.platform.kernel.ValidationException;
import oracle.iam.platform.kernel.ValidationFailedException;
import oracle.iam.platform.kernel.spi.ValidationHandler;
import oracle.iam.platform.kernel.vo.BulkEventResult;
import oracle.iam.platform.kernel.vo.BulkOrchestration;
import oracle.iam.platform.kernel.vo.Orchestration;
public class CustomValidationEventHandler implements ValidationHandler {
     @Override
     public void initialize(HashMap<String, String> arg0) {
     // TODO initialization
          System.out.println("init validate event handler");
     @Override
     public void validate(long processId, long eventId, Orchestration orchestration)
     throws ValidationException, ValidationFailedException {
          System.out.println("Beginning of validation");
          System.out.println("End of validation");
     @Override
     public void validate(long processId, long eventId, BulkOrchestration arg2)
     throws ValidationException, ValidationFailedException {
     // TODO - N/A
          System.out.println("Bulk Orchestration not yet implemented");
Now when i create a user it is not allowing and i am getting system error in the front end and in the logs i could see something below
<May 28, 2012 3:03:29 PM CEST> <Error> <oracle.iam.identity.usermgmt.impl> <IAM-3050029> <The user cannot be created due to validation errors.
oracle.iam.platform.kernel.ValidationFailedException: Event handler CustomValidationEventHandler implemented using class/plug-test.iam.eventhandlers.CustomValidationEventHandler could not be loaded.

I have implemented preprocess and postprocess event handler before with similar kind of plugin registration, metadata import and everything worked fine. Not sure what is the problem here with validation event handler.
Thanks
DK

Instead of registering the plug-in can u try placing it in the plugins folder under Oracle_IDM1/server folder.
at times restart is required. esp when the server is running in production mode.

Unable to expand table (or 'any' object) node - permissions issue?

I am the dba for a database and hence have access to the system user. When I connect to the db through SQL Developer, I can expand the table node under any user and list tables. As I can with any object node.
I now want to create an admin user that has restricted capabilities, one of which will be to view objects, such as tables etc..
(I will ultimately do this via a role to allow multiple users to have the admin capabilities, but for now have just created an admin_user userid).
However, when I connect to the database using this admin_user userid, I am unable to expand any object node.
I have played with different permissions, granting 'select any dictionary', 'select_catalog_role', 'select on dba_tables' but the user still can not view any objects via the appropriate node. eg. attempting to go to Other Users - username - Tables just shows nothing. (There are no filters).
However the admin_user can run a SQL command to view the tables. eg. Select * from dba_tables, will list all tables for all users within the database. So they DO appear to have the appropriate access.
So why can't they see the tables in the tables node?
Is there some piece of configuration within SQL Developer itself that I have overlooked?
Cheers

Event on placing the library object on the document

Hi,
I'm lokking for the technical event (like kBeforeOpenDocSignalResponderService) when any Object from the Indesign library is placed on the opened document.

This should help
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/97-deferred-trainstop-navigation-1528557.pdf

Is event handling possible with any object?
