Conditional Dynamic Action

Good Afternoon, everyone.
This is my problem, I created a dynamic action to append a value of a
text field with autocomplete named P3_OBJECT on a shuttle when I press the button "add".
I use javascript for that.
But I only want for this action to be triggered when this query return
at least one row: SELECT DISTINCT OWNER||'.'||OBJECT_NAME
FROM DBA_OBJECTS
WHERE OWNER||'.'||OBJECT_TYPE=:P3_OBJECT;
I tried to put the dynamic action to be conditional with a sql exist expression, but it didn't work.
Can anyone give me any suggestions on how I can solve this problem?
Regards, Leandro Freitas.

Oh, i see. Got it. So if you just change your javascript to pop the value of P3_OBJECT up in an alert does it work? Just want to rule out JS logic error.
I'm also assuming you get no javascript syntax errors in your system console either?
Also, did you try:
WHERE UPPER(OBJECT_TYPE) = UPPER(:P3_OBJECT)
Or if you remove the condition, does the value pass? Again, just dumping out an alert?
It could be that the condition is always failing.
Having to start with basic stuff. Flying a little blind.

Multi-condition Dynamic actions

Is it possible to have multi-condition dynamic actions e.g. hide field A if field B is null and field C is set to 'ABC'

Hi Pod,
yes but in that case you have to use a JavaScript Expression as condition type. In your example that would be
($v_IsEmpty("B") && $v("C") === "ABC")Regards

IRR dynamic action filter does not work when condition set.

Hi All
I've set up a filter on an Interactive report using a dynamic action. The fiilter is used to display records that expire within a term ( example 30,60,90 days.) The dynamic action is set to fire On Change. This all works fine as long as I do not set the report condition to only display when P1_DAYS is not null.
I am using a report template that includes #REGION_STATIC_ID# as referenced in this post -
http://anthonyrayner.blogspot.com/2010/07/report-filtering-with-apex-40-dynamic.html
I hoped not to display a blank report region .. wait until after the user selects the "term" before displaying the results. Any workaround suggestions would be appreciated.

Refer to Tabular Form field in Condition of Dynamic Action

I tried to filter on this topic but didn't come up with anything.
Is there a way to refer to a field in a tabular form as a condition of a dynamic action?
For example, I want to pop up a message (javascript 'alert') when the value of one field in a tabular form is changed, but only if another field for that same row meets a certain condition. So let's say the field in the condition is XYZ. So in the condition section, i would have PL/SQL Expression - XYZ IS NULL. Something like that. How would I refer to that XYZ field from my tabular form in the condition section of a dynamic action?
Thanks in advance.
John

Thanks for your help on this. I think going with the action being an 'execute javascript code' is a good approach. So here is my situation - I have a tabular form. I have 2 fields (among others) - SPECIES and WEIGHT. The SPECIES is a select list in the tabular form. The WEIGHT is a text box in the tabular form.
To make this simple, let's say this is for only one species - SNSG. If the person changes the select list to SNSG and the associated WEIGHT field is NULL, I need to pop up a message that says 'Fill in weight field if selecting SNSG'.
So here is what I have:
Event: Change
Selection Type: jQuery Selector
jQuery Selector: :.speciesClass
Condition: In List
Value: SNSG
True Action: Execute JavaScript Code
** Here is where I am stuck: In the JavaScript code I need to this:
If WEIGHT is null THEN:
confirm('Warning: Enter weight if entering SNSG species.');
I am not sure how to write that "If WEIGHT is null THEN" part in javaScript and be able to refer to the WEIGHT field associated with the SPECIES value I just changed in the tabular form.
I hope that makes sense!
I appreciate your help!!
Thanks,
John

Hi JTan414,
I have check the expression you have provided and there are many incorrect using of this expression, please check and do some modification as below:
For the MonthName function you should follow the grammar like:
=MonthName(10,True)
=MonthName(Month(Fields!BirthDate.Value),False)
="The month of your birthday is " & MonthName(Month(Fields!BirthDate.Value))
You have add the dataset name "DealStarts" at the wrong place, it should like below:
=Last(MonthName(Month(Fields!BirthDate.Value)),"DealStarts")
or
=Last(MonthName(Fields!IntegerValueField.Value),"DealStarts")
This will return the last value from the dataset
There is no function named launchdate, expression "launchdate ("RowofTrendingVisibility")" is incorrect and you shouldn't add the datasetname in this way.
If the expression involved of conditions from two different datasets, limit kinds of functions will support to use:
=Last(Fields!BirthDate.Value,"DataSetName")
=First(Fields!BirthDate.Value,"DataSetName")
More details information about how to use expression in SSRS:
Expression Examples (Report Builder and SSRS)
If you still have any problem, please try to provide more details information about your requirements and also some sample data.

Create two dynamic action
1. Make it order number item disable on page load.
   Event : Page Load
   Action : Disable
   Fire When event result is : True
   Selection Type : Item
   Item : Your order number item
2 . enable and disable order number on selection of order type(assuming when order type is null it is disable otherwise it is enable)
    Event : Change
    Selection type : item
    Item : your order type item
    condition : is not null
True Action
    Action : Enable
    Fire When event result is : True
    Fire on page load : True

Conditional on dynamic action result?

I have a form that has a dynaminc action on it that sets the value for an item P2_Date. The value is queried from another table. In most cases, the query will return a date for the item and it works out well. This item is triggered upon picking a DA_Number. Once the DA_Number is selected from the form, the dynamic action is summoned, the query does its querying and populates the date field with a date (P2_Date). However, there are some cases that the query will return a NULL value (there is no date associated with the selected DA Number). On the form, the request field looks blank, like there's nothing there. So once I hit submit, the date is left blank on my report
Is it possible to place a conditional on that value that is queried (P2_Date)? Once I select a a DA Number, if it returns a NULL/blank for the P2_Date field, I want the user to be able to select the value/date and capture that date to be submitted. I already have the date field set as a "DatePicker", but when I enter in a date, it is not being captured
Is there anyway to capture this? Thanks in advance.

Dynamic Action with KeyCode check for ENTER button pressed

Hi,
I want to create a dynamic action which executes if the ENTER button of field P1_NAME is pressed.
I thought about this type of DA:
Event: Key Press
Selection Type: Item(s)
Item(s): P1_NAME
Condition: Javascript expression
Value: this.triggeringElement.keyCode == 13
That unfortunately doesn't work! Dynamic action doesn't get executed...
Hope for help! :)

I found the solution in my own blog: :)
Event: Key Press
Selection Type: Item(s)
Item(s): P1_NAME
Condition: Javascript expression
Value: this.browserEvent.keyCode == 13

Dynamic Action, validation check, on an Item, could not use Change event

I am learning how to use Dynamic Actions in a 3.2.x app that was upgraded to 4.0.x. I wanted to share what I learned adding client side validation with these actions. Perhaps an Apex guru could suggest an easier method to use this feature.
I have an existing function where a user selects multiple rows in a report page, and then assigns a single status and enters justification text for the selected rows in another page, then saves changes (via submit).
One item, justification, is required. I replaced my JavaScript validation of an empty value, e.g., P10_JUSTIFICATION.value, with a dynamic action. The Change event was a candidate for this item, with the "is not null" Condition. However, it is possible to initiate this screen to review the status, overlook the justification text and immediately select a button to save changes. No Change event has fired. The Before Page Submit event was applicable here. This Event selection in the wizard does not provide the Item for definition and then the Condition wasn't the right context though available for selection. I selected JavaScript expression for the Condition, actually entered my original JS test expression, and created one True Action. The True action displays an Alert to tell the user that required text is missing.
Test of this DA was not completely successful. The alert appeared but the page went on to submit anyway. I found I had to add another True Action, Cancel Event, to stop the submit. The DA was then successful.
The Apex site examples, [http://st-curriculum.oracle.com/obe/db/apex/r40/apexdynactions/apexdynactions_ll.htm] , do a great job showing use of Change and Set Value events for Items but a user may not always navigate through items. These features were promoted for developers with no to little knowledge of JavaScript to use Apex for application development. This DA required using/understanding JS anyways.
My next step is to implement actions on a tabular form that that has required values. It is disconcerting that I have read in the forum that the column value references such as f0x and its row number are required to get it all working (as a DOM or JQuery selector). I have already found that tabular form columns can be re-ordered from v3.2.1 to 4.0.x. I was hoping I could declare dynamic actions or simpler Javascript methods that would not rely on f0x array references.
Thanks,
Kelly

It is disconcerting that I have read in the forum that the column value references such as f0x and its row number are required to get it all working (as a DOM or JQuery selector).Not necessarily. One possibility is to use descendent jQuery selectors to attach the dynamic action event handler by column heading:
td[headers="HIREDATE"] input

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!

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 checkbox using jQuery selectors

Aim: Have a classic report with a checkbox for each record that fires a dynamic action. I'd like to source the relevant ID/value within Javascript (ultimately PL/SQL)
Consider a classic report using the following query
SELECT label
,apex_item.checkbox
(p_idx => 15 -- f42
,p_value => id
,p_attributes => 'id="f15_'||id||'" class="xyz"'
) chk
FROM my_tableDefine a dynamic action with
Event: Click
Selection type: jQuery selector
jQuery selector: .xyz
No condition
Scope:Bind
I have an action executing javascript
var me = this.triggeringElement;
console.log('me:'||me);
console.log('name:'||me.attr('name') );
console.log('id:'||me.attr('id') );
console.log('value:'||me.prop('val'));Affected elements Selection type: Triggering element
When I run the page and check a box, the DA fires, but all output shown in the console log is blank.
I've tried copious variations to get this right, such as using $(this.triggeringElement)
These pages make me feel confident I have the syntax right

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 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.

Patrick
