Dynamic Actions: Advanced Techniques

I created a page that calls APEX_PLSQL_JOB.SUBMIT_PROCESS to run a stored procedure. APEX_PLSQL_JOB.SUBMIT_PROCESS returns the job number which I store in a hidden page item named P38_JOB_ID. I created a dynamic action on the page named DISPLAY_JOB_STATUS which shows a report region named Current_Job if P38_JOB_ID is not null and hides it if is null. The driving sql behind the Current_Job region is:
select job
, owner
, enduser
, created
, status
, system_status
from apex_plsql_jobs
where job = :P38_JOB_ID
The report displays correctly when I submit the job but unless I press F5 to refresh the page the system_status column will always remain SUBMITTED. It does not change to IN PROGRESS or COMPLETE automatically. How do I create a dynamic action to make the report refresh when the system status or any column in the report changes?

The above solution of periodically refreshing report is the current reliable solution to reflect the change of data in the backend.

Populating Text Field using Dynamic Actions is not working

I've a Select List (P14_ACCOUNT) and Text Field (P14_BILLING_ADDRESS_1) on a form. On selecting a value on the Select List, I've to populate the Text Fields by fetching its values from the database by using the Select List value as the primary key. To do this, I created a Dynamic Actions (Advanced) on the Select List, with event onchange and Set Value as SQL. However this is not working.
Below are the sqls of Select List and Dynamic Action respectively:
select ACCOUNT_NO || ' - ' || COMPANY_NAME display_value, ACCOUNT_ID return_value
from ACCOUNT
order by 1
select a.address1 from account a where a.account_id = :P14_ACCOUNTNow when I substitute the Dynamic Action sql with any of the below sqls, the value shows up:
select address1 from account where account_id = 41
select address1 from account where rownum=1
select user from dualI thought of seeing the value of :P14_ACCOUNT in session or debug, but session does not show any value and on clicking debug it throws a popup message "Debugging is not enabled for this application."
I've been trying since few hours but with no luck. How can I debug further?
Thanks for the help.

Hozy,
Take alook at your application on apex.oracle.com
The session state for items, when SQL is used, is set using the Page Items to Submit parameter as has been set in your application.

Dynamic action on text box change does not working

i have a page with following components.
a report that has and edit link.
a text box to catch the primary key from report link when it is clicked
a number of elements (text boxes, check boxes and LOVs) which are used as data entry form.
Now my design is that user enter values save them and no sooner did they save, the report depicts new
values. if user want to edit any record, they click on edit link and the data entry form elements
should now bring all those values from DB on page. i m successful to pick primary key and bring
it in a hidden text box and wrote a dynamic action on its change event that will bring values from
DB and set all page elements. but but but.........the change event doesnt work. it only work
when focus is lost from the text box...!! offcourse user wont want to click in that "hiddent" text
box and then click some where else to bring values in page data entry form......
help is humbly requested from forum or if any other solution approach is to be used easier than
one i m using, would be appreciated.
thanks in advance for reading my bore question :)

bundles of thanks for reply. i m going to elaborate.
1. My page no is 3.
2. Hidden Item name is P3_EDIT_ACTIVITY_ID
3. Data entry form, hidden item and the report are on the same page.
4. on the edit link of report, i have used following settings.
    Target: Page in this application
     Page: 3
     and i set hidden item as follows......
     Item 1   P3_EDIT_ACTIVITY_ID         Value #ACTIVITY_ID#
   well, when i click the link on report it does bring Activity_Id in the hidden box (which is not yet hidden for debugging purpose)
Next i wrote Dynamic action which fires on the change event of P3_EDIT_ACTIVITY_ID and run PL/SQL code with in it which is as follows
declare
Dept varchar(50);
begin
   select my_dept into Dept from activity_main ACTIVITY_ID = :P3_EDIT_ACTIVITY_ID;
   :P3_Dept := :Dept;          (i did use :P3_Dept := Dept also but this wont work)
insert into testdynamic (stamp) values (Dept); (I did this to check whether correct value is brought from DB, yes it works correctly, correct Dept is being inserted in stamp column)
end;
i have created another true action to check when the dynamic action is fired. its very simple alert. and the problem is, it only fires when focus is lost from the P3_EDIT_ACTIVITY_ID. i mean, when u keep changing value inside the text box, nothing happens, when u go outside, the alert is fired and so the pl/sql procedure. but the line
    :P3_Dept := :Dept;       OR      :P3_Dept := Dept;         arent working which is the actual requirement.
I m not using set value here as i have to set a lot of values on page not one. further. plz let me get rid of this lost focus thing as i want the form to be populated with correct values related to P3_EDIT_ACTIVITY_ID as the user click on any edit_link in the report.
Thanks for persistence. i hope i have provided all the details.
looking forward.

Dynamic action with interactive report region refresh

Hi!
I'm using APEX 4.02
I've got a page with 2 regions.
Region1 is a (input) form
Region2 is an interactive report on the same table as region 1
When entering values on the form I'm trying to dynmically lookup similar records in the table with the interactive report.
I've made a dynamic action on the change of the form fields which should refresh the interactive report region. I can see this one fires if I add a alert to debug if it fires.
The dynamic report is based on a query with bind variables pointing to the form fields, for example
where
field1 = :P2_FIELD1
This works great on the page load, so no dynamic action is fired but I can see the rows in the report region are the ones I am looking for.
But the refresh of the report region is not working, it is never refreshing and/or showing the correct data after a change of the form fields, so it looks like the dynamic action "refresh region" is not working on the interactive report.
Any ideas why this can go wrong ?
I would like to solve this using standard dynamic actions and preferrably not via PL/SQL or JS, shoudl be possible if I should believe the documentation... ;)
Cheers
Bas

Hi,
When you change value to item, I assume you do not set value to session state.
Use interactive report advanced attributes "Page Items to Submit" , set items session state before report is refreshed.

Dynamic action with set value on date field

Hi,
I'm using APEX 4.02
I'm trying to calculate the age based on the date of birth dynamically on a form. I'm trying to do this with a (advanced)dynamic action with set value.
I'm able to get this kind of action working based on a number field etc, but NEVER on a date field.
I've read all posts on this subject but so far no solution. Even if I try to simply copy the value over to another date field or typecast it to a string ( to_char function ) it does not work. So for me the problem seems to be in the source field being a date field.
I've tried using the source value as is in a select statement :
select :P33_GEBOORTEDATUM from dual;
and also type casted based on the date format :
select TO_DATE(:P33_GEBOORTEDATUM,'DD-MON-YYYY') from dual
but still no luck.
On the same form I don't have any issues as long as the calculation is based on number fields, but as soon as I start using dates all goes wrong.
Any suggestions would be greatly appreciated. If you need any extra info just let me know.
Cheers
Bas
b.t.w My application default date format is DD-MON-YYYY, maybe this has something to do with the issue .... ?

Hi,
Create a dynamic action named "set age" with following values.
Event: Change
Selection Type: Item(s)
Item(s): P1_DATE_OF_BIRTH
Action: Set value
Fire on page load: TRUE
Set Type: PL/SQL Expression
PL/SQL Expression: ROUND( (SYSDATE - :P1_DATE_OF_BIRTH)/365.24,0)
Page items to submit: P1_DATE_OF_BIRTH
Selection Type: Item(s)
Item(s): P1_AGE

How to clear grey loading screen and animated gif (Dynamic Action with "Show Processing" on submit)

APEX V4.2.3
DB 11.2
I have a classic report on page 1. I have a region button called "Export" (defined by a submit dynamic action with "show processing=Yes") that submits the page and then via a branch directs me to page 2 which has a slightly different version of the report on page 1 (i.e. no breaks) which I want to capture as a CSV export. Therefore I've set the report template on page 2 to " Export:CSV".
Now when I click on the page 1 export button the grey screen and loading gif appears indicating that the report is executing and then as expected, page 2 doesn't appear but instead the standard open/save window's dialog box appears asking to open or save the generated CSV file. All good..but the grey loading screen remains. How do I clear this loading screen and get back to the context of page 1 ?
thanks in advance
PaulP

Hi PPlatt,
We would love to help but you left out one crucial part of the puzzle: namely how does your CSV report get exported. With the way it is setup (a redirect to another page), I'm going to assume you do that because you have some PL/SQL on that page that prints the CSV.
Now there are two questions that are crucial here:
- How do we stop the icon from bugging us on the screen
- How do we communicate with the browser that it should no longer display the loading icon
The first question is rather easy, two simply lines of codes can do that:
$('#apex_wait_popup').hide();
$('#apex_wait_overlay').hide();
But when do we use this code? Quite simple when the document is downloaded. When is it downloaded? At the end of the PL/SQL code that prints the document to the browser.
What you could do is at the end of that code give an application item a certain value. For example :AI_PRINTED := 'Y';
Then all you need to do is let the browser ask for the value. You could do this by using JavaScript to continuously fire AJAX to the server using a JS timing event:
http://www.w3schools.com/js/js_timing.asp
Better would be a Server send event, but since you left out another crucial piece of information: your browser, I will not go deeper into this.
Start this timing event when someone asks for the document, and end it as soon as the process returns that :AI_PRINTED equals 'Y'.
Despite the lack of information, I hope I have given, or at least inspired you to get to the solution.

Joni

Dynamic Action based on Interactive Report Select List Value

I'd like to perform a Dynamic Action when a user selects one of 3 options from a Select List within an Interactive Report:
select APEX_ITEM.SELECT_LIST(
p_idx => 3,
--p_value         =>   deptno,
p_list_values => 'Copy;Copy,Delete;Delete,Export to PDF;Export to PDF',
--p_attributes    =>   'style="color:red;"',
p_show_null => 'YES',
p_null_value => NULL,
p_null_text => '--Select--',
--p_item_id       =>   'f03_#ROWNUM#',
p_item_id => 'P6_IR_SELECT_LIST',
p_item_label => 'Label for f03_#ROWNUM#',
p_show_extra => 'YES') "Actions"
from dual;
When building the Dynamic Action, I chose the following values from the Advanced wizard
Event: Select
Selection Type: DOM Object
DOM Object: P6_IR_SELECT_LIST
Condition: Equal to
Value: "Delete"
True Action: Execute Javascript Code: Alert('Here');
Doesn't seem to be firing...can anyone help?
Thanks in advance,
John

Hi,
I am not sure if the "equal to" condition applies to a DOM object... after all, a DOM object can be anything (any HTML element) not only a field.
Try using a javascript expression instead, like this:
$v('P6_IR_SELECT_LIST')=='Delete'UPDATE: Sorry, I just tested and "equal to" condition works for DOM objects... should have tested before posting!

Info group being not called while using Dynamic Actions

Hi,
I am facing a scenario that, while we execute some action from PA40 like termination, then it will call my subroutine for dynamic actions which will be calculating the last day worked and updating the same in Info Type 0041.
For updating the IT 0041, i am using the function module HR_MAINTAIN_MASTERDATA. and IT0041 is getting updated properly. But now the problem is coming that when the control comes out of subroutine, it is going back to the PA40 Screen and not to the next screen of the Info group.
What can be the cause for the same.
RND I have done on my part: I have commented/uncommented the return parametre RP50D-Date1, commented/uncomented the use of function modules to lock and Unlock the pernr.
Please give ur comments.
Thanks in Advance.

Hi Nisha,
Not sure if I have understood correctly, but if you just wanted to calculate leaving date and write the same date in IT0041 then you don't need a function module:
1. Create a small program, as follows:
REPORT ZHR_PY_R0008                           .
INCLUDE MPPDAT00.
TYPE-POOLS HRQTA.
TABLES: P0000,
        RP50D,
        T001P.
ROUTINE CALLED BY TABLE T588Z
FORM CHANGE_DATE.
RP50D-DATE1 = P0000-BEGDA - 1 .
ENDFORM.                    " CHANGE_DATE
This program will give you the last working day written to RP50D-DATE1
2. Simply enter the following lines into table T588Z:
0000 04 499*- LEAVING ACTION - Populate Infotypes with leave date -*
0000 04 500 P T001P-MOLGA='08'
0000 04 501 P PSPAR-TCLAS='A'
0000 04 502 P PSPAR-MASSN='*'/X   (* equals your leaving action types)
0000 04 503 P PSPAR-MASSN='*'/X   (* equals your leaving action types)
0000 04 504 F CHANGE_DATE(ZHR_PY_R0008)
0000 04 505 ******** INF.0041 ********
0000 04 506 I COP,0041,,,(P0000-BEGDA),(P0000-ENDDA)/D
0000 04 507 W P0041-DAR07='*'   (* equals your date type)
0000 04 508 W P0041-DAT07=RP50D-DATE1
or if you are simply looking to delimit IT0041 with the leave date then replace lines 506-508 with:
0000 04 506 I MOD,0041,,,(RP50D-DATE1),(RP50D-DATE1)/D
0000 04 507W     P0041-ENDDA=RP50D-DATE1
This will solve your problem : - )

Date Picker with Dynamic Action

Hi
I have a situation where a DA is fired onchange of a date field using the apex 4 date picker item type.
The DA does a number of calculations and database requests, so it can take a few seconds over our slow internet connection.
While the DA is executing, the calendar remains displayed. The application demands that I display at least 1 or preferably 2 months as well as the current month to facilitate the user entry, which means much of the page is obscured. Not only would it be nice so see the various fields in multiple regions being updated progressively, it would also be reassuring for the user to see that the application has not "hung".
Is this the expected behavior? Is there a technique to close the date picker before the DA actions are triggered?
Thanks for your advice.
CS

Hi,
Try this write a Zprogram for this.
REPORT Zget_date.
TABLES : RP50D, PA0041, P0041, PA0019.
PERFORM Z_date.                       "3CML Dynamic action for IT0000
FORM Z_date.
DATA: DATE1 LIKE SY-DATUM.
DATA: DATE2 LIKE SY-DATUM.
SELECT * FROM PA0041
           WHERE DAR01 EQ '11'
            AND PERNR = P0041-PERNR
            AND BEGDA = P0041-BEGDA.
    DATE1 = PA0041-DAT01.
    DATE2 = DATE1 + 1.
    RP50D-DATE1 = DATE2.
    EXIT.
ENDSELECT.
ENDFORM.
and use this in your dynamic action.
F Z_date(Zget_date)
W P0041-DAT01=RP50D-DATE2
Hope this will solve your problem.

Dynamic Action on apex items

Hi,
I have a requirement like after entering the date of birth in the item. then age value should be set dynamically.
how can i set the value?

Hi Tulasi,
Follow the below steps
Click on create button-Dynamic action
select Advanced type
Give some name
event - On change
selection type - item
item(s) - your page item(used to select date of birth)
condition - no condition
action - Execute PL/SQL code
Fire on page load - blank
PL/SQL code -
declare
v_age varchar2(100);
v_dob date;
v_sysdate date;
begin
select sysdate into v_sysdate from dual;
v_dob := :P1_DOB; //here P1_dob is a page item from where i am selecting date of birth.
select trunc(to_char((v_sysdate - v_dob)/365)) into v_age from dual;
:P1_AGE := v_age; // i have created one item named P1_AGE to display the calculated age.
end;Page Items to Submit = P1_DOB // replace with your datepicker page item
Page Items to Return = P1_AGE // replace with your item.
Hope this will give you some idea.
Thanks and Regards,

Dynamic action on show region

Hi,
Application Express 4.1.0.00.32
I have a report region on a page that is conditionaly displayed based on the value of a page item Pn_ITEM = 'HIDE'.
I have dynamic actions that run on the page that populate a collection and refresh the report without the need to submit the page. However I need to somehow show the report when the collection has at least one member present.
I have tried the following:
1st true action executes pl/sql that adds a record / member to a collection, then a 2nd action sets the value to a page item Pn_ITEM = 'SHOW' and a 3rd true action that should show the region based on the set value from true action 2.
My collection has a member added. The value 'SHOW' is applied to my page item Pn_ITEM by the dynamic action however the report region that I now want displayed is not showing. Obviously if the page is submitted the report will now be shown however I cannot submit the page at this point thats why I need to do this dynamicaly or through javascript and on demand processes.
Any ideas how to get my report region to display once the collection has at least one member without submitting the page?
Thanks in advance.

Remove the condition for display from the region. You don't want to have this here since it will completely stop the region from rendering if the condition is not fullfilled at rendering time. You want it rendered, just not displayed.
Add css to the region (inline, class):
style="display: none;"Add a true action which will do a refresh on your region (Component - Refresh, select your report region as an affected element).
Now either:
Add a true action of type execute javascript. Since you can't put conditions on true actions, we'll test the condition in javascript.
Pick one:
if($v("Pn_ITEM")=='SHOW'){
//if you want to target the region to be shown by an ID (static id?)
$("#region_id").show();
if($v("Pn_ITEM")=='SHOW'){
//if the triggering element would be the region to be shown
$(this.triggeringElement).show();
if($v("Pn_ITEM")=='SHOW'){
//if you'd want multiple affected elements to be shown at once drop the [0]
$(this.affectedElements[0]).show();
};Create a new dynamic action which has the same triggering conditions as your other dynamic action.
Specify a when condition:
$v("Pn_ITEM")=='SHOW'Create one true action of the type 'Show' to show the region.
End result should be your dynamic action creating an element in the collection, a refresh of the report based on the element (but still not shown), and finally a show of the region.
Don't forget that the actions will also need fire on page load (so don't forget to check the checkbox on the true actions), otherwise the region will not be shown initially.
I'd say that the item is probably not necessary anymore, but that depends on any other logic you might have on your page and possibly interacts with it.

Dynamic Action on IT0002 for France-Molga 06

Hello,
I would like to set up a dynamic action on IT0002 for France (Molga 06) - field State - 'GBDEP'.
The field 'GBDEP' is a mandatory field for France, but the business is not maintaining the record of the Birth State of an employees.
So I would like to set up a dynamic action to create a default value for this field. The default value created is 999 and it will filled while creating IT0002 record for France during Hiring Action.
I am not quite well versed with dynamic action, so i would appreciate a help in how to set up this dynamic action.
I can share if more information is needed.
Thanks in advance.

Try this dynamic action:
INFTY     SUBTY     FNAME     OPERA     SEQNO     KENNZ     VINFO
0000               06     10     *     *FRANCE DEFAULT GBDEP
0000               06     12     P     PSPAR-TCLAS='A'
0000               06     14     P     T001P-MOLGA='06'
0000               06     16     P     PSPAR-MASSN='XX'
0000               06     18     I     INS,0002,,,(P0000-BEGDA),(P0000-ENDDA)
0000               06     20     W     P0002-GBDEP='999'
Here, XX is your hiring action code. Also, make sure you have a 999 entry in V_T005S for FR.
Hope this helps.

Dynamic Action on new row in Tabular Form

Hi Guys,
APEX version is 4.1
I created a dynamic action on change of a select list, if changed then disable the related fields on the same row.
This is working fine for all EXISTING rows on the tabular form.
However, if I click on ADD ROW button, a new row is added to the page, but the change event on select list is
not triggerred from the dynamic action.
Is there any thoughts or workaround on this interesting problem?
Thanks in advance,
Frank

I got it working by adding a onchange event which is triggering js function on the page.

Dynamic action on File browse change event

Hi Experts,
apex version 4.1
This is what i'm trying to do..
i have a file browse control and a text field. when user selects a file, selected fiel's name (without file type extension) should be set to text field.
I tried adding a dynamic action to file browse control's change event and within pl/sql Set Value logic i queried the wwv_flow_files and tried to return the file name it didn't work. i got no data found error. i assumed file is being inserted into wwv_flow_files when a page submission happens.
In my second approach within the SetValue pl/sql logic i got the file browser control's (by directly accessing field, not by querying wwv_flow_files)value and did some string manipulation and tried to return only the file name. yet i got the same no data found error.
Any idea how can i implement this ?
Thanks in advance.
