Select List problem

I have 3 select lists: the first two are with submit and the last one is just select list. Each list depends on the previous one.
I have set null and default values for each list. The problem occurs when I first start the application, but after selecting an option in the first list all is fine and when I reset the fields everything works as it should.
So the problem only occurs when the application is first launched....
This is the error message:
Error: ORA-01858: a non-numeric character was found where a numeric was expected performing List of Values query: "SELECT TESTTIME d, TESTTIME r FROM TESTSETUP WHERE TESTDATE = :P3_TESTDATE and TERM = :P3_TERM ".
How can this be corrected?
Any help would be greatly appreciated.
Thank - Greg

I have set null and default values for each list
These values are not available in committed session state for the subsequent select lists to use.
Solution: Create a OnLoad Before Header computation (conditional upon the value of the select list being null) to set it to whatever null/default value you want. This will "initialize" the value so that your dependent select lists can work properly.

Multiple value selection lists - Problem filtering

I'm builing a news application with publisher, and one of the fields is a multiple value selection list. We're filtering news stories to different pages based on the values. Problem is, I can't get the right content items to display. I did it no problem with a single selection box. The code I'm using is:
<pcs:foreach expr="folderByPath(folder, '../../Articles')" var="articles">
     <pcs:foreach expr="articles" var="art">
          <pcs:if expr="art.testkeyword == 'choice2'">
               </pcs:value>"><pcs:value expr="art.headline"></pcs:value></a><br />
          </pcs:if>
     </pcs:foreach>
</pcs:foreach>
So if 'choice2' is in a single select list, no problem. If it's part of a multiple select, I get nothing. I'm thinking I'm missing something really easy, like logic operators. But I couldn't find anything of help in the documentation

Hi,
Make use of contains function.
Syntax : contains(string1,string2) this returns true if string 1 has string 2
Usage
<pcs:if expr="contains(test,'A')">
</pcs:if>
** 'test' is the name of the multi select box

E-recrutiing Selection List Problem

Hi,
I am using E-Recruiting version 3, service pack 13 and I am having problems with the Selection List on the Requesting Person page.
When I log in as a Requesitng Person and select the "Selection List" link I am presented with an empty table. But the Requesting Person has raised Requisitions that have been approved and appicants have applied. There are also questionnaires waiting to be completed.
Does anyone have any suggestions as to why this doesn't work?
Thanks,
Jon

Hi Sebastian,
Nice to know tht your solution for the above problem is working fine. I got the similar problem now. I could see the entries in the selection list in the requester page for the first time and also assessed a questionnaire from there (requester page's selection list) and the ranking results are also displayed in recruiter's page.
But when I re-test it, I found no entries in it from tht time. I have cross checked all ur replies above, every thing is fine, I created another requester page and tried many times, from tht minute on wards, every requester's page has empty selection list. I did not manke any changes any where but still the selection list is empty after testing once.
Pls help me with a solution to my problem.
Thanks & Regards,
Sudheer Kumar P.

Report with Select Lists problem

Hi all,
I have a sql report with this query:
select
'Hello World' Col1,
apex_item.select_list_from_lov_xl(1,'Data 1','TEST_LOV') lov1,
apex_item.select_list_from_lov_xl(1,'Data 2','TEST_LOV') lov2,
apex_item.select_list_from_lov_xl(1,'Data 3','TEST_LOV') lov3,
apex_item.select_list_from_lov_xl(1,'Data 4','TEST_LOV') lov4
from dual
Where TEST_LOV is a LOV that return 400 rows. The problem is that this report gives me an error:
report error:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
I am able to create a workarround using ajax, but I don't think this is the best way.
Does anyone knows why this happens or any solution??
Thanks,
Alejandro.

Hi,
OK - My page is defined as:
The report is based on the following SQL:
select
"EMPNO",
"EMPNO" EMPNO_DISPLAY,
"ENAME",
"DEPTNO"
from "#OWNER#"."EMP"The DEPTNO column is the one that I need a select list for. I have not used the APEX_ITEM package to handle this, but I expect it could be done that way as well.
On the DEPTNO column, I have the following settings:
Display As: Select List (query based LOV)
Named LOV: -Select Named LOV-
Display Extra Values: Yes
Display Null: Yes
List of values definition: SELECT NULL d, NULL r FROM DUAL
Note that it is important that you use these exact settings.
I have then created a new PL/SQL region on the page below the tabular form. The region should use the "No Template" template to keep it hidden from view. The Region Source is:
DECLARE
vSEP VARCHAR2(1);
BEGIN
vSEP := '';
htp.p('<script type="text/javascript">');
htp.p('var sMaster = new Array(');
FOR c IN (SELECT DNAME d, DEPTNO r FROM DEPT ORDER BY UPPER(DNAME))
LOOP
htp.p(vSEP || 'new Array (' || c.r|| ',"' || c.d|| '")');
vSEP := ',';
END LOOP;
htp.p(')');
htp.p('</script>');
END;This defines a hidden select list as a javascript array using the actual values from the DEPT table.
I then have an HTML region underneath that, again using "No Template", that has the following as the Region Source:
<script type="text/javascript">
function updateList(sChild)
var o;
var sChildValue = sChild.value;
sChild.options.length = 0;
o = new Option('-Select-', '');
sChild.options.add(o);
var k;
for (k = 0; k < sMaster.length; k++)
o = new Option(sMaster[k][1], sMaster[k][0]);
sChild.options.add(o);
sChild.value = sChildValue;
if (sChild.selectedIndex == -1)
sChild.selectedIndex = 0;
function updateLists()
var lists = document.getElementsByName("f03");
var k;
var x;
if (lists)
for (k = 0; k < lists.length; k++)
updateList(lists[k]);
updateLists();
</script>For this example, you will note that I am refering to "f03" (in the updateLists() function) - my DEPTNO column's SELECT tags have "f03" as their NAME attributes. This may need to be changed for your page.
And that's it!
When the page is loaded, the tabular form is constructed. Due to the settings I've applied to the DEPTNO column, each list will actually consist of a NULL entry and the value on the record (that's due to setting Null/Extra Values to Yes).
Then, a hidden select list is constructed as a javascript array. And, finally, we loop through each of the "f03" items on the page, take a note of the value already there, replace the contents of the dummy select list with the contents of the array and then select the original value again.

Problem writing a sql query for a select list based on a static LOV

Hi,
I have the following table...
VALIDATIONS
ID          Number     (PK)
APP_ID          Number
REQUESTED     Date
APPROVED     Date
VALID_TIL     Date
DEPT_ID          Number     (FK)
I have a search form with the following field item variables...
P11_DEPT_ID (select list based on dynamic LOV from depts table)
P11_VALID (select list based on static Yes/No LOV)
A report on the columns of the Validations table is shown based on the values in the search form. So far, my sql query for the report is...
SELECT v.APP_ID,
v.REQUESTED,
v.APPROVED,
v.VALID_TIL,
d.DEPT
FROM DEPTS d, VALIDATIONS v
WHERE d.DEPT_ID = v.DEPT_ID(+)
AND (d.DEPT_ID = :P11_DEPT_ID OR :P11_DEPT_ID = -1)
This query works so far. My problem is that I don't know how to do a search based on the P11_VALID item - if 'yes' is selected, then the VALID_TIL date is still valid. If 'no' is selected then the VALID_TIL date has passed.
Can anyone help me to extend my query to include this situation?
Thanks.

Hello !
Let's have a look at my example:create table test
id        number
,valid_til date
insert into test values( 1, sysdate-3 );
insert into test values( 2, sysdate-2 );
insert into test values( 3, sysdate-1 );
insert into test values( 4, sysdate );
insert into test values( 5, sysdate+1 );
insert into test values( 6, sysdate+2 );
commit;
select * from test;
def til=yes
select *
from test
where decode(sign(trunc(valid_til)-trunc(sysdate)),1,1,0,1,-1)
       =decode('&til','yes',1,-1);
def til=no
select *
from test
where decode(sign(trunc(valid_til)-trunc(sysdate)),1,1,0,1,-1)
       =decode('&til','yes',1,-1);
drop table test; It's working fine, I've tested it.
The above changes to my first idea I did because of time portion of the DATE datatype in Oracle and therefore the wrong result for today.
For understandings:
1.) TRUNC removes the time part of DATE
2.) The difference of to date-values is the number of days between.
3.) SIGN is the mathematical function and gives -1,0 or +1 according to an negative, zero or positiv argument.
4.) DECODE is like an IF.
Inspect your LOV for the returning values. According to my example they shoul be 'yes' and 'no'. If your values are different, you may have to modify the DECODE.
Good luck,
Heinz

Upgrade to 10.1.3.4: Problems with multi-select list

Hi,
We upgraded from BiseSEone (10.1.3.2) to 10.1.3.4 (using BI EE). One of the features we were longing for was the improved multi-select list in the dashboard prompts (with a efficient search support). But after the Installation the multi-select list doesn't work at all. There are no data offered and the frames are missing. What could be go wrong here ? There were no problems during the installation. I told the installation to keep the configurations.

Problems with customizing select lists and popup LOVs

Hi
I have 2 problems about select lists and popup LOVs.
The first one is about a select list in a tabular form.
It should be created with APEX_ITEM.SELECT_LIST_FROM_LOV or similar and take its values from a named LOV.
This worked fine but now it should also have the possibility to enter a free value.
I tried to accomplish that by creating a APEX_ITEM.POPUP_FROM_LOV, but there is a problem with the function that is called by the arrow icon right to the input field (for eg. genList_f11_5()).
If the row is added by addRow, then it works fine, but if the row is is not empty
then the function call is like genList_f11_$_row() and the input field gets no value, when a LOV option is selected.
The other problem is about a select list which should have the possibility to enter a custom value and
also there should be the possibility to select several values. I tried to implement this by a text area containing the selected values and a multiple select list, with an event handler in each option. The user could click options and they would be copied to the text area. The problem is that I couldn't make the event handler work in IE.
I would appreciate any ideas about either of these problems.

Hi,
If you download application you can see source.
I have not write any instructions, sorry.
If you are on Apex 4 you can just load jQuery UI autocomplete library and take ideas from my app.
If you download my sample in zip there is uncompressed htmldbQuery library.
You can see that and take only function htmldbAutocomplete.
Then check jQuery UI document
http://jqueryui.com/demos/autocomplete/#method-search
There is method search that you can use open list just by click of input.
I hope this helps at start.

Select List (based on LOV) query problem

Hello experts! I have a small problem here, which I can't seem to overcome.
I have a page item (select list based on LOV), which is based on a query. The query returns all potential employees of a department that are responsible for a certain duty. So far so good!
The problem is that there are two departments, which should not only see there own employees but also the name of the employee that has carried out a certain task. However, due to my query, the name of that person is not displayed - only the pk is returned.
Do you have a recommendation how I display all employees of a specific department and have additional values translated as well?
My query is as follows: select str_bearbeiter, cnt_bearbeiter from vt_tbl_bearbeiter where cnt_bearbeiter in (SELECT
CNT_REGIERUNGSBEZIRK FROM TBL_REGIERUNGSBEZIRK) union select str_bearbeiter, cnt_bearbeiter from vt_tbl_bearbeiter where int_behoerde in (SELECT
CNT_REGIERUNGSBEZIRK FROM TBL_REGIERUNGSBEZIRK where STR_REGIERUNGSBEZIRK = lower (:app_user)) whereas :app_user holds the information of the department.
Any hint is appreciated!
Many thanks,
Seb

Okay, I just had the right idea and it's working well! Sorry for posting!
I return the name of the employee that has edited a dataset and simply add all others of the logged on department! Really easy! Should have thought of that before posting! ;-(
The correct code is select str_bearbeiter, cnt_bearbeiter from vt_tbl_bearbeiter a, vt_tbl_punktdaten b where a.cnt_bearbeiter = b.int_bearbeiter and
inv_pt_id_sub = :P4_PTIDS
union select str_bearbeiter, cnt_bearbeiter from vt_tbl_bearbeiter where int_behoerde in (SELECT
CNT_REGIERUNGSBEZIRK FROM TBL_REGIERUNGSBEZIRK where STR_REGIERUNGSBEZIRK = lower (:app_user))Bye,

Chart based on Select list with submit Lov problem

Hi,
I have one page with interactive report showing username with links, date and
database actions.
Another page contains one region having flash chart based on select list with submit Lov.
The lov is created by dynamic query.
Every time when i click the 1st page report link, the 2nd page lov is populating the value automatically. But the problem is chart displays NO DATA FOUND message though the LOV has many values.
I don't want to display any null values so set to NO for LOV
I tried to write Before header computation (PL/SQL Function Body) to set the lov value, but the query is displayed as such.
I don't want to assign any static default value also as the values are dynamic for every link.
The following is my Before header computation of Select list with submit (Item name is p11_schema). (PLSQL Function Body)
begin
if :p11_schema is null then
return 'select distinct owner schema1, owner schema2 from auditing
where access_date=' || :p11_access_date
|| ' and username=' || :p11_username
|| ' order by owner';
end if;
end;
This is my chart query.
select null link, obj_name label, sum(sel_count) "Select", sum(ins_count) "Insert", sum(upd_count) "Update", sum(del_count) "Delete" from auditing
where username=:p11_username
and access_date=:p11_access_date
and owner=NVL(:p11_schema, OWNER)
group by owner, obj_name
Example: If there more than one records in the lov, the graph should display the 1st record. When i select another record, the chart accordingly display the selected values. But inially it should not display "NO DATA FOUND" message.
I tried using all the combinations of computation type for the lov, SQL query ( I could not use if conditon then), PLSQL expression, PLSQL function body. But it does not work out.
Can anyone please help me out.
Thanks.

Hi Scott,
Thanks for your reply.
I found out the solution for this problem as below.
But i did it in different way to tackle the dynamic query wich returns more than one record using rownum always the 1st record when it is empty instead of assigning constant (static) value like '1'. And i am returning LOV itself for both null or not null condition as below.
Declare
q varchar2(4000);
begin
if :p11_schema is null then
q:='select distinct owner schema from auditing';
q:=q || ' where username=:p11_username ';
q:=q || ' and access_date=:p11_access_date ';
q:=q || ' and rownum<2 order by owner';
Execute immediate q into :p11_schema USING :p11_username, :p11_access_date;
end if;
return :P11_SCHEMA;
end;
Thanks.

Apex 4.0 Cascading Select List: ajax problem with german umlaute

Hi everybody,
Apex 4.0
Dad PlsqlNLSLanguage: GERMAN_GERMANY.WE8MSWIN1252
I have problems with german umlaute and ajax cascading select lists (Cascading LOV Parent Item).
The data is populated without a page refresh in the select list when the parent select list changes but special signs like german umlaute are shown as weird characters.
Seems like there is some charset problem with ajax.
This is the only part of the application where special signs like umlaute are messed up. Everything else is fine.
I allready tried to figure out if I can escape the umlaute in the javascript (file apex_widget_4_0.js) but no success here.
Can anybody help me with this issue?
Thanks in advance,
Markus

Hi Markus,
your specified character set in your DAD is wrong. As mentioned in the installation instructions at http://download.oracle.com/docs/cd/E17556_01/doc/install.40/e15513/otn_install.htm#CHDHCBGI , Oracle APEX always requires AL32UTF8.
>
3. Locate the line containing PlsqlNLSLanguage.
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:Regards

Row ranges 1-15, 16-30 in select list has refresh problem

Hi, Gurus:
I use APEX 4.1.1 with Oracle 11GR2. I have a question that was discussed before here, but I still have trouble to understand it. I have some reports that cannot refresh content when I choose another page of the same report. I used row ranges 1-15, 16-30 in select list with pagination. It did not work. However, I used the exactly same report page settings for some other queries producing exactly same columns, except the query logic is slightly different thus number of rows in report are different. row ranges 1-15, 16-30 in select list with pagination works well in other reports.
I came across discussions and set partial page refresh to no for those report pages with refreshment problem. This time it worked well, but it was extremely slow as my query is very slow. I was wondering why some of report do not need to set partial page refresh to no and have no problem to refresh, but some of reports have problem to refresh (I even copied the report page without problem for those reports with problem and just change queries.)? Is there any other way to refresh these reports quicker other than SQL tuing?
Please help me.

Javascript / Select List with Submit problems

I have a page (page 3) where I can either edit or create a record. If I am editing a record, the data loads on page 3 via a PL/SQL block. On page 3, I have a textual item with Javascript linked to it which pops up a new window. In the Javascript, I am passing three values to the next page. Two of those values (P3_ITEM1, P3_ITEM2) are 'Select List with Submit'. If I am creating a new record from page 3, the Javascript works fine and the popup window comes up when I click on the textual item. However, if I am editing an existing record, I get an error when I click on my textual link. Looking at the address bar, it is not passing the value of P3_ITEM1 and P3_ITEM2 to the next page. It does, however, pass the value of P3_ITEM3 (not a 'Select List with Submit') to the next page. Again, the Javascript popup works fine if I use the 'Select List with Submit' fields to populate P3_ITEM1 and P3_ITEM2 (i.e. if I submit those fields) and it does not work if P3_ITEM1 and P3_ITEM2 are already populated when page 3 loads (i.e. if I do not submit those fields). Looking at the session variables, it appears as though P3_ITEM1 and P3_ITEM2 are set prior to clicking the link which initiates the Javascript. However, the URL in the popup window says the value of those fields is 'undefined'. Does anybody have any idea what I can do to make this work or why it is not working? Thanks.

Hello Chris,
It seems like you are having some problem with setting/reading session state, but it’s really hard to pin point the problem without seeing any code. Can you post your two pages on apex.oracle.com?

HT201210 Contact List Problem.   I have duplicates on my iPhone. I turned off my Contact and selected "Delete Contacts" Most of the contacts were deleted but about 120 were left on my phone.   I've tried selecting individual contacts and deleting them,

Contact List Problem.   I have duplicates on my iPhone. I turned off my Contact and selected "Delete Contacts" Most of the contacts were deleted but about 120 were left on my phone.   I've tried selecting individual contacts and deleting them, No Go.
Can anyone help?   How do I get rid of these contacts so I can re-synch my iPhone.

I have exactly the same problem on my ipad. It is happening on only some contacts but, as with you, when I delete one of the contacts on the ipad, the second ipad contact and the contact on the imac are also deleted. This is even the case when I have differentiated the two contacts on the ipad and can see the one I have deleted on the ipad is not the same one as is then deleted on the imac.

Problem with cascading select lists

Hi All,
I have two select lists on a form, category and sub category. When I select the category the sub-category list gets populated and a report is displayed. When I select the sub-category the report listing re-displays limited by sub-category. Works fine.
However, when I go back and select another category, the report returns no data on the first attempt. In debug mode I note that although visually the sub-category has been reset, the session value has not, and so the report is selecting on an invalid combination of category and sub-category.
How do I get the sub-category to reset when the category changes?
I have tried an onChange javascript entry on the form attribute but it does not work since APEX inserts its own onChange before my one.
Suggestions please...thanks in advance.
Sajit

Hi,
can you setup an example on apex.oracle.com which fails so that we can have a look.
Or you can use Firebug for Firefox and have a look what is sent to the server and what the response it. Check the "Console" tab. I suspect you will see an error when you trigger the refresh.
