Dynamic Action character issues.

Hi,
I have an issue in Application Express 4.0.1.00.03.
I am using a dynamic action to populate a field value.
When I have a £ symbol (ascii 163) it is converted to � (ascii 65533).
As far as I can see the issue would be the character set for the ajax request to/from the database.
How can I change this and get my £ symbols back?
Regards
Michael

Hi Michael,
your PlsqlNLSLanguage setting is the problem. As per the Oracle APEX Installation instructions http://download.oracle.com/docs/cd/E17556_01/doc/install.40/e15513/otn_install.htm#CHDHCBGI
The PlsqlNLSLanguage setting determines the language setting of the DAD. The character set portion of the PlsqlNLSLanguage value must be set to AL32UTF8, regardless of whether or not the database character set is AL32UTF8. For example:
PlsqlNLSLanguage AMERICAN_AMERICA.AL32UTF8...Regards

Issue in execution of Dynamic action on change event

Hi,
Greetings.
I have scenario, where I have one select list (P_CATEGORY) and one shuttle control (P_ROOMS) on page.
The values of the shuttle list is being populated based on the selected value in select list.
The left pane of shuttle control's value based on LOV and source of the shuttle item is a plsql function, which returning colon separated value list.
So that returned values shown in the right pane of shuttle.
The LOV values are getting being populated using cascading LOV i.e based on the of Select List item. But the Shuttle source values not getting auto refresh and for achieving that I've created a dynamic true action on change event of Select list.
The dynamic action is with :
Action : Set Value
Set Type : PL SQL funciton body
Page items to submit : P_CATEGORY (this is select list)
Escape Special Character : Yes
Suppress Change event : Yes
Affected Elements -
Selection type : Item(s)
Item(s) : P_ROOMS
This is perfectly working on Firefox but not working on IE9 & Google Chrome.
I've debugged in both IE9 & Google chrome and found the dynamic action get executes ajax call and the values get back but not rendering on the screen. i.e not assigning to the item.
So can you please advice me what will be a workaround for this issue?
I am using Application Express 4.1.0.00.32 .
I'll appreciate your prompt response.
Thanks & Regards,

I don't understand why this is not working withouth seeing an example, there might be multiple processes working on the item.
Anyway if the value is returned check if the value is in the session aswell. If it is in the session but not on the page that means you will need to find a way to bring it from the DB to the page. You can do this by adding an action to your DA:
Action: Execute PL/SQL code
PL/SQL code: NULL;
Page Items to Return: your shuttle item

Performance issues with dynamic action (PL/SQL)

Hi!
I'm having perfomance issues with a dynamic action that is triggered on a button click.
I have 5 drop down lists to select columns which the users want to filter, 5 drop down lists to select an operation and 5 boxes to input values.
After that, there is a filter button that just submits the page based on the selected filters.
This part works fine, the data is filtered almost instantaneously.
After this, I have 3 column selectors and 3 boxes where users put values they wish to update the filtered rows to,
There is an update button that calls the dynamic action (procedure that is written below).
It should be straight out, the only performance issue could be the decode section, because I need to cover cases when user wants to set a value to null (@) and when he doesn't want update 3 columns, but less (he leaves '').
Hence P99_X_UC1 || ' = decode(' || P99_X_UV1 ||','''','|| P99_X_UC1 ||',''@'',null,'|| P99_X_UV1 ||')
However when I finally click the update button, my browser freezes and nothing happens on the table.
Can anyone help me solve this and improve the speed of the update?
Regards,
Ivan

END;

Hi Ivan,
I do not think that the decode is performance relevant. Maybe the update hangs because some other transaction has uncommitted changes to one of the affected rows or the where clause is not selective enough and needs to update a huge amount of records.
Besides that - and I might be wrong, because I only know some part of your app - the code here looks like you have a huge sql injection vulnerability here. Maybe you should consider re-writing your logic in static sql. If that is not possible, you should make sure that the user input only contains allowed values, e.g. by white-listing P99_X_On (i.e. make sure they only contain known values like '=', '<', ...), and by using dbms_assert.enquote_name/enquote_literal on the other P99_X_nnn parameters.

Issue with Dynamic Actions - Infotype 0041 Updation

Hi All,
Requirement :
I have to update the Date type-13 ( Resignation Date - DAR11 ) without Date ( DAT11 as Blank value - User will fill through Infogroup ) while performing the Termination action through PA40.
Added below code in V_T588z (0000):
I have added 186,188 Lines.Other lines are standard thing.
              04     180     P     PSPAR-MASSN='10'/X **Termination
              04     181     P     PSPAR-MASSN='ZB'/X **Termination
              04     182     P     PSPAR-MASSN='14'/X **Termination
              04     185     I     COP,41,,,(PSPAR-BEGDA),(PSPAR-ENDDA)/D
              04     186     W     P0041-DAR11='13' **BEGIN & END OF CRA01670 CODE ***
              04     188     W     P0041-DAR11='' **BEGIN & END OF CRA01670 CODE ***
Issue :
1. The above logic is not working for Finland ,other countries. For only India it is working.
2. Some times Date type-13 is coming twice while through the Infogroup-0041 screen twice,which is incorrect. The infotype-0041 should call only once.I have checked the User parameters,MOLGA,USR. But it is not working.
2. The standard configuration Date type -09-Last day of work - is working fine . But i could not be able to find ,from where it is coming.I have checked the Dynamic actions,but no use.
Need your inputs to solve the issue.
Thanks,
N.L.Narayana

Dynamic Actions issue

Hi Experts,
Is it technically possible to know if an Infotype was updated through the Dynamic Actions or manually by an end user.
We have a case where an Infotype is updated in the background based on certain conditions through a dynamic action.
The same Infotype could be in certain circumstances updated manually through PA30.
Is it possible to know how the last change was done???
Thanks for your help.

Thank you for your reply.
In fact we have a custom Infotype (IT9xxx: Eligibility for certain benefit) that we are automatically creating/updating in the background based on changes in IT0021; if a new dependant is added in IT0021, we automatically create for him a new instance in this custom Infotype etc...
Sometimes and for some special cases, the end user should update this IT9xxx manually.
Now, if I want to know each records in this IT9xxx were created manually and each ones were created automatically, is it possible or not ??? in other terms from a system point of view, do we have a flag or an indicator to tell us if the record was created/updated through dynamic action or manually.
I hope that it more clear now.
Thanks again.

Leaving a Page fires "Page Unload" dynamic action?

Hi,
Which Dynamic Action fires when I am leaving a page.
I have a page with lot of items, I want to fire alert based on some condition when user leaving that page (suppose user clicks to say some TAB), I used *"Page Unload"* dynamic action, but somehow it's not working.
Is there any other Event I have to use?
Thanks,

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 field DIVGV not working

We have built the dynamic action below to default values from infotypes 0007 and 0008 behind the screnes in infotype 0491 Payroll Outsourcing. The issue that we are having is that the dynamic action will not work for field P0008-DIVGV, but will work with all the other fields.
The only difference between the DIVGV field and the rest of the other fields mentioned in this dynamic ation is that it seems to be a free text field (which you can modify), even though the values are pulled from the work schedule rule in infotype 0007. We have also hidden the DIVGV field in 0007 per client requirement.
Does anyone have any suggestions on how to get this working. Do we need to populate these values in any of thh HR tables first?

Hi Damas,
it seems to be no specific reason for not updation P0008-DIVGV only.Please cross check whether field is populating or not in Infotype 0008, before dynamic action triggered, other that that there is no reason.

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 .... ?
Edited by: user3338841 on 3-apr-2011 7:33

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

Problem setting a hidden item value when button clicked with dynamic action or pl/sql process

Apex 4.1
Oracle 11g
I have a page that consists of a main region and several sub regions. I have a pl/sql process in After Header SET_DISPLAY(:P400_DISPLAY :='MAIN';)
Three subregions have a contional display where P400_DISPLAY = STORE. This works in hiding the sub regions.
Now I want to change the P400_DISPLAY value to STORE to show the subregions when I hit a button.
I tried creating a dynamic action for on click of the add button but get the following error:
The selected button uses a 'Button Template' that does not contain the #BUTTON_ID# substitution string
I went to the templates and found:
Substitution Strings
Substitution strings are used within sub templates to reference component values. This report details substitution string usage for this template.

Generated button ID will be either the button's Static ID if defined, or if not will be an internally generated ID in the format 'B' || [Internal Button ID]
I then tried creating a page process, pl/sql, :P400_DISPLAY :='STORE'; when the appropriate button is pressed. The button action is submit page. However, it does not change the P400_DISPLAY value and the subregions stay hidden.
Suggestions please on how to fix the template or change the P400_DISPLAY value?

The root issue is that, although you change the value of your page item, it isn't visible to other areas of the page until it is in the session. So, any other action based on the value of your page item; the visibility of a control, a report based on the item's value, etc. will all be unaffected by changing the value of the page item until it has been changed in the session. Even after this the items are stored in the session, you must thereafter do something to cause the value to be reevaluated. To see the effect of this, observe that your page loads and evaluates the value of your page item, it sees that is "MAIN" and hides the regions. However, it doesn't reevaluate them after this.
So; your choices to get this value set in the session are to either Submit the page, or use JavaScript to set the value in the session. If you use the latter of these, you'll have to do some further work to cause the visibility tests to be re-run, So, let's stick with with the submit method.
What you've done above sounds correct for this but, there are a lot of decisions you could have made that might have caused things not to happen in the correct sequence.
Firstly, let's confirm that what I describe above is your problem. From the development environment, load the page, click the button to change the value and submit. Now, click the link labelled Session. Is it still set to MAIN? If so; this is your issue.
Let's start with the your After Header computation. Did you set it to *only* run if the current value of your page item is NULL??? If not, that's your problem.
Load Page -> Item set to 'Main' by Computation -> Click Button -> Item set to STORE -> Submit -> Load Page -> Item set to 'Main' by Computation
See the problem?
Assuming this isn't the issue, you created a Branch to the same page, right? What is your process point for the Branch? Is it *After* Validation, Computation etc? Because if not, you aren't changing the value before the submit happens.
I bet it is the first issue but, take a look at these.
Cheers,
-Joe

How can a classic report be filtered using one select item and dynamic action?

APEX 4.2.1
DB 11g
I have a page with 4 reports on it. The top report is an interactive report and the following 3 are classic reports. The users would like to be able to use a select list to filter the 3rd report by PO line number without refreshing the entire page.
After verifying that the report is set to allow partial refreshes, I took the following steps
1. Created a PO Line select item (p_po_line_select) in the same report region
2. Added p_po_line_select to the report query
3. Created a dynamic action on p_po_line_select with 2 true actions
     1. Set value (p_po_line_select)
     2. Refresh report region.
The Set Value dynamic step was not working; I would get an out of memory error at line 2, memory stack error, or the value did not get saved to session state depending on the settings I selected. I was able to get it working with the following set:
1. Action = Set Value
2. Set type = PL/SQL Expression
3. PL/SQL Expression = :p_field_does_not_exist
4.   Page items to submit = blank
5. Selection Type = Item(s)
6. Item(s) = p_field_does_not_exist
p_field_does_not_exist does not exist as a page or application item which leads me to believe that this is a bug and I am just lucky that it worked. I would rather know how to do this properly. Can someone please provide a link to a working example of how this should be done or state which settings are wrong?
I was able to reproduce the issue in the following app

Unable to create a dynamic action ALERT to be generated on a Select List when particular value is selected.

Hi everyone, this should be so easy, yet I am stuck.
I have a form region with an item P110_VESSEL_ID. This item is a select list. It is based on the query:
select distinct v.vessel_name, v.vessel_id
from vessels vessels v, frequent_fishermen ff
where ff.dea_permit_id = :G_PERMIT_ID and
ff:vessel_id = v.vessel_id
UNION
select v.vessel_name, v.vessel_id
from apex_collections a, vessels v
where collection_name = 'SUPVES_COLLECTION' and
a.c002 = v.vessel_id
If the user decides against the values in the select list query, they may opt to SELECT ALL VALUES. This SELECT ALL VALUES is a POST ELEMENT TEXT on P110_VESSEL_ID.
<a id="popVessels" href="#"><font color=blue>Select from ALL Vessels</a>
This all works fine.
The issue is that when the user selects a vessel name = 'UNKNOWN' and it's corresponding vessel_id value, I would like an ALERT to appear indicating that they should double check that the vessel is UNKNOWN and not that the is no vessel.
I created a dynamic action
event= change
select type = item
item = P110_VESSEL_ID
True ACtion #1 is the ALERT.
I currently have no other logic, but cannot even get this to work. Any thoughts. I have also tried the SELECT TYPE = jQuery Selector = select[name='P110_VESSEL_ID'] but that does not work either (though I am not certain if the value should be P110_VESSEL_ID or the static name of VESSEL_ID).
Any help is appreciated.
ps. the page is not submitted when the vessel is changed. There is other data that needs to be entered both in this region and others and many validations run when submit, so the submit would not be an option.
thanks again,
Karen

This should work. Sometimes I've see where there is other javascript on the page that may have some errors and is causing the dynamic action code to not be executed. Use your favorite browser script console to try and determine if this may be the case.

P.S. Your jQuery selector can be: select#P110_VESSEL_ID

Dynamic action on LOV using tabular form

Hello,
I realize this has likely been dealt with somewhere already, but I'm going to ask anyway.
I have a master/detail form. The detail form has an option to add rows. I have created a dynamic action as defined below...
True Action:
Sequence: 10
Action: Javascript Expression
Fire On Page Load: No
Code: $(this.triggeringElement ).val()
Sequence: 20
Action: SQL Statement
Fire On Page Load: No
Code: select travel_status from territories_summary_v where territory_code=:P3_FIND_COUNTRY_CODE and language='US';
Sequence: 30
Action: Javascript Expression
Fire On Page Load: No
Code: $(this.triggeringElement).closest("tr").find("td[headers='TRAVEL_STATUS_CODE'] input").val($v('P3_FIND_COLOR'));
The P3_FIND_COLOR and P3_FIND_COUNTRY_CODE are defined as hidden fields.
This DA seems to partially work. It will update the travel status code with the proper value for each line. I can see it on screen. But when I apply changes it doesn't save this particular value to the database. If I physically go to the field and type something in, it will save this field. All other values save ok... just not this column .. regardless of the number of detail lines.
Further to this, when I add a row and a new blank row appears, if I change the country, the DA does not fire at all. I've put an alert in on sequence 10 and the alert will fire for a pre-existing row in the table... but not a new row. I would have thought that because it's an onChange DA associated with the country code, it would work for each new row regardless of how many rows are added or whether its a new row vs existing row.
So the first issue is why it won't save the data that is populated in travel status code when I can clearly see it there? Secondly, why this DA is not firing when I add a new row?
If anyone can help me it would be appreciated. I've done a lot of searches but have not come up with much where these issues are concerned.

There is no way to make a good guess on this without an example. It is hard to say what the reason could be.

Dynamic Action on tabular form: to auto set value for all changes rows

Hi All:
I am using APEX4.2.3 and I am not very familar with JQUERY or Javascript.
I am having a tabular form to support Update and Delete action. The tabular form has 4 columns:
Column A: ID                      (Number)     : Read-only column
column B: Name                 (Varchar2)   : Editable
Column C: Age                    (Number)     : Editable
Column D: ChangeFlag      (Varchar2)   : Read-only column                             ==> however, I want this column been automatically upldated by my APEX application
Here is the requirement: First user update Column B, or C or both for # of rows; then user click "Save Change" button. For ALL updated rows, I need to automatically update Column D with below logic:
For a given row,
               IF Column D IS NULL THEN
                     set value = 'M'                           -- M means modified
               ELSE --- column D has a value already
                    IF last character of Column D is 'M', THEN
                           don't do anything;
                    ELSE
                          set value of D = existing value + 'M'                       (here + means concatenate
                   END IF;
            END IF;
I thought this can be done by creating dynamic action on tabular form ... I have researched this on this forum and can't find a good match example ..
I know I can implement this using a DB trigger; however, I want to learn if this can be achived via Dynamic Action.
Thanks!

Dynamic Action On Date Picker

Hi,
I need help with understanding dynamic actions. I have two date pickers, I want the value of the first date picker to be the minimum date of the second date picker. To achieve this I have a hidden item whose value I want to reflect the selected date in the required format. In the dynamic action on the date picker I have no condition, and the true action is set to execute the following pl/sql code
:P200220000_Y_MIN_DT := TO_CHAR(TO_DATE(:P200220000_Y_STR, 'DD-MON-YYYY'), 'YYYYMMDDHH24MI');. The items to submit field contains both the first date picker and the hidden item.
The "P200220000_Y_MIN_DT" is now passed into the minimum date field of the second date picker. The problem is when the date is changed the hidden item does not get the value until the page is refreshed.
Am I doing something wrong or just have not mastered the use of dynamic action or are my colleagues right use AJX call backs not dynamic actions.
Thanks
Aderemi

Hi Aderemi,
first of all as already explained, the min/max values are already used on the server side when the necessary code for the date picker is rendered. When you changed the referenced values in the browser, these values will not change the behavior of the client side date picker widget. But when you submit the page, the new min/max values will be used by the date picker validation check on the server.
To over the client side date picker display issue, you could directly call the date picker JavaScript code and pass in the new min/max values. Have a look at http://jqueryui.com/demos/datepicker/
So for example you could have a dynamic action of type "Execute JavaScript code" which executes the following Javascript code.
apex.jQuery('#P200220000_MY_DATE_PICKER').datepicker("option", "minDate", "-1m");I think that should work. Note: I haven't tested if that really works and it's also some kind of unsupported, because it uses the underlaying jQueryUI APIs the APEX date picker is using. This could change in the future and would invalidate your code.
