Is it possible to change trigger firing sequence by program?

Hi,
I would like to know if there is a command like set_item_property or set_block_property or set_lov_property which can allow to change by program a trigger firing sequence. I do not find any, so i think i have to do it manually in property palette of the trigger. Thanks for your answer.

Thx
To change Execution Hierarchy of a trigger, we go into Property palette of that trigger to change this property, i want to know if it is possible to change this property by program without need to go into Property palette of that trigger, EXECUTE_TRIGGER executes an indicated trigger but how to change Execution Hierarchy (for example set_lov_property sets the given LOV property for the given LOV, we use set_lov_property in the program and do not need to go into property palette of this lov), hope you understand what i would like to do. thanks for your help.

Forms trigger Firing Sequence

Does anyone know where I can find details on firing sequence of each type of triggers on Item, Block and Form levels?
Can I set the Debugger to trace the actual sequence of firing of triggers at run-time?

(V45) Trigger Execution Sequence in Forms 4.5
=============================================
Introduction
This document lists the order in which triggers fire in Oracle Forms 4.5:
o The first column, Action, describes the function to be performed
(e.g. deleting a record).
o The second column, Trigger Firing Order, describes the order
in which triggers fire after a function is performed.
o The third column, Level, describes the level (form, block, item)
at which the trigger fires. This was accomplished by creating a form
with all the triggers invoked. If a trigger could fire at all levels,
it was included at all levels. Such a trigger fires at the lowest level
at which it is defined.
Key triggers and triggers which fire via buttons or check boxes are
not included.
This bulletin does not cover every contingency and covers only the
most commonly used actions.

Trigger Firing Sequence?

Hei Guys
I have a form where I have a date and time field(text fields). I have a OK/SAVE button, which is subclassed, and executes do_key(commit_form), which in turn executes form level key-commit trigger. On the key-commit trigger, I have some program units, which basically validate the form, and then commit the form.
On the time field, if I change the time(which the system calculated when I hit a button), I do some validation in the when-validate-item of the field.
The code in the time text-fields, when-validate-item is as follows.
fp_check_time(:BL_COMPLAINT.APPT_TIME);
declare
     lnu_error number;
     alrt_id alert := find_alert('AL_CONFIRM');
     some_number number;
begin
     --some_number := fpkg_error_handler.fp_message('UEM','0000','ERROR','@when-validate APPT_TIME');
     --set_item_property('bl_ok_cancel.pb_ok', enabled, property_true);
     if :BL_COMPLAINT.APPT_time <> nvl(:parameter.APPT_TIME, '*')     then
set_alert_property(alrt_id, alert_message_text, 'You have changed the system recommended date. This could lead to double booking. Do you want to continue ?');
if show_alert(alrt_id) = ALERT_BUTTON1 then
if spkg_med_schedule.sf_chk_valid_datetime
          (:BL_COMPLAINT.SICK_CALL_SERVICE_GROUP,
'1',--check nurse
:parameter.p_clinic,
:BL_COMPLAINT.APPT_DATE,
:BL_COMPLAINT.APPT_time) = 'N' THEN
     lnu_error := FPKG_ERROR_HANDLER.FP_MESSAGE('UEM','0000','ERROR','The date/time you have selected is not valid. Please change the date/time.');
     :BL_COMPLAINT.APPT_TIME := :parameter.APPT_TIME;
     --set_item_property('bl_ok_cancel.pb_ok', enabled, property_false);
      raise form_trigger_failure;
end if;
else
          some_number := fpkg_error_handler.fp_message('UEM','0000','ERROR','@when-vaidate APPT_TIME not ab1');
     :BL_COMPLAINT.APPT_TIME := :parameter.APPT_TIME;
--     :parameter.error_occur := 'TRUE';
     --set_item_property('bl_ok_cancel.pb_ok', enabled, property_false);
     raise form_trigger_failure;      end if;
end if;
end;
I have this code even in the date field. which is also a text item.
I am hoping you might have noticed, a couple of Raise form_trigger_failure in the code. But, the processing, does not stop there and continues processing and tries to commit the form.
[b1.]Why does that happen?

> continues processing and tries to commit the form
It would help if you would describe what you mean by "tries to commit". What does the form do?
The first thing you need to do in your commit processing sequence is:
Validate(form_scope);
If not form_success then
    Raise form_trigger_failure;
End if;The above code will stop the commit if an edit error occurs. If you don't validate and check for success, commit processing continues, and you will probably get multiple error messages popping up before the commit process finally stops.

Possible to change the variables in the program permanently?

Is it possible to change the content of the variable in the MIDlet application??

Hello,
As there is no beans mechanism in J2ME, here is what you can do. You can save values into RMS and then fetch them from there when you load the MIDlet.

Prevent of trigger firing because of program process

Consider we have a combobox and a datagridview all in vs2013, with the following triggers :
combobox.SelectedIndexChanged : when the event fires, the datagridview is filed up with the appropriate data, according to the new selection.
datagridview.SelectionChanged : when this event fires, the detailed information for the current row-data is displayed.
In the process of the combobox.SelectedIndexChanged event, I use a datagridview.rows.clear() statement to clear the datagridview, before the new data stored on it.
In this case when the datagridview.rows.clear() statement is executed, the datagridview.SelectionChanged event fires, with unpredictable results.
Any idea on how to prevent of firing datagridview.SelectionChanged event ?
Thanks in advance
George

you can add and drop the handler when needed (remove the handles from the event if you use below method),
AddHandler datagridview1.SelectedIndexChanged, AddressOf datagridview1_SelectedIndexChanged
RemoveHandler datagridview1.SelectedIndexChanged, AddressOf datagridview1_SelectedIndexChanged
OR
keep track of some boolean value you set to true or false depending if you want to execute the code in the event, so something like
Private gridupdate as boolean = false
Private Sub ComboBox1_SelectedIndexChanged_1(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
gridupdate = false
datagridview.rows.clear
End Sub
Private Sub datagrid_SelectionChanged(sender As Object, e As EventArgs) Handles datagrid.SelectionChanged
if grdupdate = true then
'do your thing
end if
End Sub

Triggers Firing Sequence Of Forms 10g after commit_form trigger.

hi all,
please tell me Triggers Firing Sequence Of Forms 10g after commit_form trigger.

Hi,
I have a doubt regarding the sequence of events when COMMIT_FORM is fired.
Using the following to trigger the event.
DO_KEY('COMMIT'_FORM');
Added debug messages in my form triggers and found that after the ON-INSERT trigger is fired, the WHEN-VALIDATE-RECORD is fired and then the PRE-RECORD.
However this sequence is not specified in the lists of firing sequences mentioned here.
Is it possible to change the sequence programmatically.
In my ON-INSERT trigger, calling a DB procedure to insert row in the table.
Thanks

Is it possible to change the frame rate of a motion template?

Motion has some very useful templates, but the majority are only offered in NTSC, not PAL. (including all in 3D TEXT PROJECTS).
Is it possible to change the frame rate to 25fps before I start adding my own stuff, so that I can easily get the timing right for a PAL sequence in FCP.
If not in Motion, how else could this been changed?

Try dragging all the groups from one project into another instead - you'll need to open both project and rearrange the windows so you can see the layers tab for both of them.

How to realize WHEN-RADIO-CHANGED- Trigger in ADF

Hy@ all,
I try to redevelop the Summit Forms Demo in ADF.
One of the existing modules is called "ORDER" and contains, among other things, radio buttons based on a database column(VARCHAR2) named PAYMENT_TYPE which contains the values CASH and CREDIT.
Based on this Item a WHEN-RADIO-CHANGED- Trigger is called which shows an alert and reset the changes to a default value when the payment type is changed but the credit rating(database column from another table) is not equal to an according value.
The code of the trigger is the following one:
DECLARE
     n NUMBER;
     v_credit S_CUSTOMER.CREDIT_RATING%TYPE;
BEGIN
     IF :S_ORD.payment_type = 'CREDIT' THEN
          SELECT credit_rating
          INTO v_credit
          FROM S_CUSTOMER
          WHERE :S_ORD.CUSTOMER_ID = ID;
     IF v_credit NOT IN ('GOOD', 'EXCELLENT') THEN
          :S_ORD.payment_type := 'CASH';
          n := SHOW_ALERT('PAYMENT_TYPE_ALERT');
     END IF;
     END IF;
END;
Now my questions are where to place the equivalent code(EO, VO, etc.?) and how to realize this.
Further, is it possible to roll out the trigger code to the database and then call this stored unit from "the right place"?
I´m using JDeveloper v10.1.3.1.0 and I´m pleased about any reply or solution.
Best regards
Chris

The answer will depend on how you are storing the parameter in your ADF application and when do you actually need it to be set and based on what.
This can be for example a property of a managed bean in your JSF application and you can initialize it either in the bean itself or in the faces-config.xml file as a managed property.

Possible to change date format when importing files into Aperture 3

Just wondering if it is possible to change the format of the date from YYYY-MM-DD to YYYYMMDD when you rename files as they are imported into Aperture 3? I typically rename my files and insert my initials, date the photo was taken, sequence number, camera used and original file name. When I do this in Aperture 3, the date format used includes dashes. I would like to have the file renamed without the dashes in the date. Is this possible?

You should be able to edit the format in the import presets. I have done this for folder stucture of imports, I believe you can do the same for the file renaming. At the bottom of the drop down box for file naming at improt should be an edit option which brings up the import naming presets, select the "YYYY-MM-DD" and remove the dashes.

Post-change trigger problem

I have problem with post-change trigger, i'm using Forms 10g
I have two block, one is database block and the other is non-database block for example A is Nondatabase block and B is Database block, I have written commit_form built-in in Key-Next-Item of a item in B(database) block. When it is getting executed commit_form built-in firing the post-change trigger of a item in A(Non-database) block. I dont know why it is firing and I dont want the post-change trigger to fire (we are not assigning any value to that item in A block during commit_form).
Can anybody help me on this..
Regards
Radha

when you issue a commit_form, forms will validate all items in all blocks which re not valid at that moment. This also occurs for non-database-block.
The question is why is the item not valid ? Are you putting something in it in some other trigger? If so, you could explicitly set the itemstate to valid with a
SET_ITEM_PROPERTY('BLOCK.ITEM', ITEM_IS_VALID, PROPETY_TRUE);btw.. you should not use the POST-CHANGE-trigger for validations etc. its better to use the WHEN-VALIDATE-ITEM-trigger.

Hi Bowie,
1.You can change the Namespace. condition is no obj's under the namesapce then only it's possible otherwise u can't.
2.create a new namesapce what ever u want and copy all the obj's under that namesapce.finally delete the previous one.
XMLAnonymizerBean
Use
You use this module to anonymize XML elements and attributes by removing namespaces or namespace prefixes from the XML document of the main payload.
You can define a particular namespace prefix for each namespace. You can also change the encoding attribute of the XML declaration.
Integration
You can use the module in adapters that can be extended in the module processor.
Activities
