How to make dynamic actions using Set Value work in all browsers?

I’m having a cross-browser incompatibility issue with dynamic actions using Set Value. The dynamic action works like a charm on Chrome but has no effect on either IE or Firefox. The code in oracle.apex.com and here are the credentials:
Workspace: DDBA
Username: [email protected]
Password: redtruck12
These code is on page 3 and here are the details:
There are two report lists (Standard and Special) and some of the reports require additional information supplied in either select lists or text boxes.
If the user selects a Standard report requiring a select list/text box, then the dynamic action sets the value of Special Reports to NULL (and vice-versa).
The dynamic action is to prevent a simultaneous selection of both the Standard and Special reports. To see how it works on Chrome, do this:
Run Page 3
Select the ‘Report for Search Criteria’ option from the Standard Report list. A ‘Search Criteria’ text box appears
Select the ‘Report by Release’ option from the Special Reports list. A select list appears and the ‘Search Criteria’ text box disappears.
If you do the same things on IE or Firefox, the text box does not disappear.

Hi,
Things are going wrong with setting the item values to NULL. If you check your session state, you'll see that in chrome your items values indeed will be set to null, but in firefox they won't.
Also I've noticed that you don't reset the other input fields, so their values persist in the session state. Since you submit your page every time you change one of the report select lists, this might lead to unexpected behaviour. Lastly, I've noticed you use a sql exists expression to manage the display/hide of your page items. A condition of type "Value of expression 1 = expression 2" causes less overhead as you don't need to switch to the db sql engine for every item to validate.
I'd suggest you rethink your specs and try to create:
- One dynamic action (since a value of standard select excludes the value of special select, and vice versa)
- Set the values for hidden items to null, also in session state
- Use a refresh of region as extra event in your dynamic action, instead of submitting your page for every change.

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 make dynamic query using DBMS_SQL variable column names

First of all i will show a working example of what i intend to do with "EXECUTE IMMEDIATE":
(EXECUTE IMMEDIATE has 32654 Bytes limit, which isn't enough for me so i'm exploring other methods such as DBMS_SQL)
-------------------------------------------------CODE-----------------------------------
create or replace PROCEDURE get_dinamic_query_content
(query_sql IN VARCHAR2, --any valid sql query ('SELECT name, age FROM table')
list_fields IN VARCHAR2) --list of the columns name belonging to the query ( arr_list(1):='name';   arr_list(2):='age';
-- FOR k IN 1..arr_list.count LOOP
-- list_fields := list_fields || '||content.'||arr_list(k)||'||'||'''~cs~'''; )
AS
sql_stmt varchar (30000);
BEGIN
               sql_stmt :=
'DECLARE
     counter NUMBER:=0;
auxcontent VARCHAR2(30000);
     CURSOR content_cursor IS '|| query_sql ||';
     content content_cursor%rowtype;
     Begin
          open content_cursor;
          loop
               fetch content_cursor into content;
               exit when content_cursor%notfound;
               begin
                    auxcontent := auxcontent || '||list_fields||';
               end;
               counter:=counter+1;
          end loop;
          close content_cursor;

     END;';
EXECUTE IMMEDIATE sql_stmt;
END;

I'm attepting to use DBMS_SQL to perform similar instructions.
Is it possible?

Hi Pedro
You need to use DBMS_SQL here because you don't know how many columns your query is going to have before runtime. There are functions in DBMS_SQL to get information about the columns in your query - all this does is get the name.
SQL> CREATE OR REPLACE PROCEDURE get_query_cols(query_in IN VARCHAR2) AS
2 cur PLS_INTEGER;
3 numcols NUMBER;
4 col_desc_table dbms_sql.desc_tab;
5 BEGIN
6 cur := dbms_sql.open_cursor;
7 dbms_sql.parse(cur
8 ,query_in
9 ,dbms_sql.native);
10 dbms_sql.describe_columns(cur
11 ,numcols
12 ,col_desc_table);
13 FOR ix IN col_desc_table.FIRST .. col_desc_table.LAST LOOP
14 dbms_output.put_line('Column ' || ix || ' is ' ||
15 col_desc_table(ix).col_name);
16 END LOOP;
17 dbms_sql.close_cursor(cur);
18 END;
19 /
Procedure created.
SQL> exec get_query_cols('SELECT * FROM DUAL');
Column 1 is DUMMY
PL/SQL procedure successfully completed.
SQL> exec get_query_cols('SELECT table_name, num_rows FROM user_tables');
Column 1 is TABLE_NAME
Column 2 is NUM_ROWS
PL/SQL procedure successfully completed.
SQL> exec get_query_cols('SELECT column_name, data_type, low_value, high_value FROM user_tab_cols');
Column 1 is COLUMN_NAME
Column 2 is DATA_TYPE
Column 3 is LOW_VALUE
Column 4 is HIGH_VALUE
PL/SQL procedure successfully completed.I've just written this as a procedure that prints out the column names using dbms_output - I guess you're going to do something different with the result - maybe returning a collection, which you'll then parse through in Apex and print the output on the screen - this is just to illustrate the use of dbms_sql.

Enter a value using set value dynamic action

Hi,
I'm using Oracle 11g XE with apex 4.0.2.
I've been trying to use a dynamic action on a text field 'item_group'. Button doesn't have this facility. I created an advanced action using 'set value' with no condition the value being 'RAM.' The event is "change", selection type 'event source', set type is 'static assignment' and value is RAM. It is supposed to trigger when the create button is pressed but nothing happens and the field is still null. I've tried variations on this but nothing works. Can anyone help.
Thanks

How to make dynamic search items in a report?

Hi all,
I have two questions.
1. How to make dynamic search (i.e without GO button) field above report to provide dynamic search by words in one field of report query?
2. How to make similar multiply dynamic search fields on report to provide individual search by selected fields of report with refine capability (i.e any search conditions in different fields must work together as complex WHERE clause)
Thanks in advance

hey yuri--
if i'm understanding your questions correctly, the easiest way to achieve the functionality you're after is to have your query criteria fields submit the page when values are entered/selected. the page should then branch back to itself using the submitted criteria in the query. because you're asking about dynamically adding in your where clause predicates, you should consider using a report region of type "SQL Query (Pl/sql Function Body Returning SQL Query)". that way you can use pl/sql to piece together your query based on the provided criteria.
so the part of your question i'm not sure of is when your page should submit itself ("without a GO button" as you said). for your first question, it seems to be a simple matter of javascript. you want users to be able to enter search criteria into a field and have that criteria be using in the report. to facilitate that we have a few self-submitting item types such as "SelectList with Submit" and "Text Field (always submits page when Enter pressed)". for your second question, it seems that you should have a Go button for the user to indicate he's done entering in his query criteria. anyhow, that's up to you, i suppose. hopefully this response will give you the concepts you need to implement this as you'd like.
regards,
raj
ps-after re-reading your post, i now realize there's a chance that you wanted users to not have to submit the page at all when filtering their result sets. if that's the case, you'd have to use javascript for that cumbersome feat. google would be a good place to go for that code.

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.

How to make Dynamically Shortened Text With "Show More"

Hi there! i want to know how to make dynamically shortened text with show more or read more in my website using HTML 5 pages or ASP.NET ?
example like these paragraphs
Lorem Ipsum är en utfyllnadstext från tryck- och förlagsindustrin. Lorem ipsum har varit standard ända sedan 1500-talet, när en okänd boksättare tog att antal bokstäver och blandade dem för att göra ett provexemplar av en bok. Lorem ipsum har inte bara överlevt fem århundraden, utan även övergången till elektronisk typografi utan större förändringar. Det blev allmänt känt på 1960-talet i samband med lanseringen av Letraset-ark med avsnitt av Lorem Ipsum, och senare med mjukvaror som Aldus PageMaker.
Det är ett välkänt faktum att läsare distraheras av läsbar text på en sida när man skall studera layouten. Poängen med Lorem Ipsum är att det ger ett normalt ordflöde, till skillnad från "Text här, Text här", och ger intryck av att vara läsbar text. Många publiseringprogram och webbutvecklare använder Lorem Ipsum som test-text, och en sökning efter "Lorem Ipsum" avslöjar många webbsidor under uteckling. Olika versioner har dykt upp under åren, ibland av olyckshändelse, ibland med flit (mer eller mindre humoristiska).
I motsättning till vad många tror, är inte Lorem Ipsum slumvisa ord. Det har sina rötter i ett stycke klassiskt litteratur på latin från 45 år före år 0, och är alltså över 2000 år gammalt. Richard McClintock, en professor i latin på Hampden-Sydney College i Virginia, översatte ett av de mer ovanliga orden, consectetur, från ett stycke Lorem Ipsum och fann dess ursprung genom att studera användningen av dessa ord i klassisk litteratur. Lorem Ipsum kommer från styckena 1.10.32 och 1.10.33 av "de Finibus Bonorum et Malorum" (Ytterligheterna av ont och gott) av Cicero, skriven 45 före år 0. Boken är en avhandling i teorier om etik, och var väldigt populär under renäsanssen. Den inledande meningen i Lorem Ipsum, "Lorem Ipsum dolor sit amet...", kommer från stycke 1.10.32.
Den ursprungliga Lorem Ipsum-texten från 1500-talet är återgiven nedan för de intresserade. Styckena 1.10.32 och 1.10.33 från "de Finibus Bonorum et Malorum" av Cicero hittar du också i deras originala form, åtföljda av de engelska översättningarna av H. Rackham från 1914.

Moved to the main Dreamweaver support forum.
There are several ways you could approach this. Here's one you might try:
Give the first paragraph an ID, such as "first", and wrap the paragraphs you want to hide in a <div> with another ID, such as "more". Then add the following block of JavaScript just before the closing </body> tag of the page:
<script>
var first = document.getElementById('first'),
     more = document.getElementById('more'),
     trigger = document.createElement('span');
trigger.id = 'trigger';
trigger.innerHTML = 'Show less';
first.appendChild(trigger);
function toggleDiv() {
var state = more.className,
       text = trigger.innerHTML;
more.className = (state == 'open') ? 'closed' : 'open';
trigger.innerHTML = (text == 'Show more') ? 'Show less' : 'Show more';
toggleDiv();
if (trigger.addEventListener) {
    trigger.addEventListener('click', toggleDiv, false);
} else if (trigger.attachEvent) {
trigger.attachEvent('onclick', toggleDiv);
} else {
trigger.onclick = toggleDiv;
</script>
This gets references to the "first" paragraph and the "more" <div>. It also creates a <span> with the ID "trigger" that's appended to the "first" paragraph. The rest of the script defines a function called toggleDiv(), which toggles the "more" <div> open and closed, and changes the text in the "trigger" <span>.
You also need to create the following style rules for the various elements:
<style>
#trigger {
    text-decoration: underline;
    color: blue;
    cursor: pointer;
#more {
    transition: ease-out .7s;
    overflow: hidden;
#more p:first-child {
    margin-top: 0;
#more.closed {
    height: 0;
    -webkit-transform: translateY(-600px);
    transform: translateY(-600px);
#more.open {
    -webkit-transform: translateY(0);
    transform: translateY(0);
    max-height: 600px;
#more + p {
    margin-top: 0;
</style>
This solution hides the text and creates the "trigger" <span> only if JavaScript is enabled in the browser. It should work in all browsers, including Internet Explorer 8 and earlier.

How to include dynamic action in bdc

Hi All,
I want to update infotype 17 when an employee has joined through PA40 (Joining action).So i have written a dynamic action for this .But this dynamic ation does not get called in bdc for joining action.

I have tried with user-exit zxpadu02 also, calling hr_infotype_operation on saving infotype 0001.But it gives return as 'Employee does not exist'.
Since that infotype 0001 is still not saved.
So what to do.

how to build dynamic databases(record set) for mobile?

In the load rule in the dimension build settings you would need to go to the tab dimension definition, choose the time dimension and right click on it. Select Edit properties. If you have not done so, set the dimension to be the time dimension. Then go to the generations/levels tab and set the generation names you need. For example if you want YTD, you would set the generation name to Year, if you want QTD set it to Quarter. You would set the number to the generation number that coorisponds to the generation. The DBAG has the list of names for all of the DTS members.
