I solved it.
I modified a bit my code "On load Page". In case of LOV i have changed this condition
if (l == undefined) {
          document.wwv_flow.f03.disabled = true;
      }with this
if (l == 105) {
          document.wwv_flow.f03.disabled = true;
      }I don't know why 105 instead of undefined, but this works. I give 105, with alert on length.

Tabular form with Popuv LOV doesn't work with onchange event

Hi all.
I have a problem with tabular forms, Popuv LOVs and javascript.
I have created one tabular form, I want to put a value in "my_field" field when a user selects a new value from other field called "my_list", I have this code:
<script type="text/javascript">
function putValue(pThis)
var vRow = pThis.id.substr(pThis.id.indexOf('_')+1);
html_GetElement('f06_'+vRow).value = '0000';
</script>and this for Element Attributes:
onchange="putValue(this);"Everything works well when I choose "Display as Text Field", but if I change this option to "Display as Popup KEY LOV" or "Popup LOV" it doesn't work, I mean "my_field" stays without any value.
I'm using Oracle Application Express Release 4.0 and Oracle 11g
Please help.
Regards.

Hi Peter.
Thanks, yes, in fact the position of my column changes, but it doesn't work even with the correct element, I have made a lot of proves and it seems that APEX constructs POPUPS LOVS in a different way and that's why "onchange" does not work.
With this thread: Re: onchange not work on popup lov for a field on collection I have a half solution, It works for existing rows, but it doesn't for added rows.
I have solved this problem calling a function that set the onchange event to every row when "ADD ROW" button is pressed, now it works without problems.
Regards.
Oscar.

Tabular form with select list not updating

I have created a tabular form with a dynamic select list
select primary_key, column1,
htmldb_item.select_list_from_query(10,column2, 'select descr d, column_value r from lookup_table where column_value = '||column1) column2
from main_table
The select list appears to work correctly but the new value is not saved to the database. I assume this is because the tabular form element display as field for column2 is set to "standard report column" but when I select any of the "display as text" or "LOV" options either the current data is not displayed or errors are generated.
Any suggestions?
Thanks,
Bob

Hi Ian,
As you have seen, sorting on the project_manager_id column will sort by the id value rather than the textual value. This is, of course, because this is the value in the field.
I haven't tried this out, but one thing that may work is the fact that you don't have to include the ORDER BY fields within the SELECT statement. You could, for example, do:
select p.project_number, p.project_manager_id
from projects p, users u
where p.project_manager_id = u.id (+)
order by u.name
Obviously, you won't be able to do this in the existing statement as you would then be blocked from using column sorting. However, it implies that if you could construct the SQL statement dynamically, appending appropriate ORDER BY strings to the end of the base select statement, you could sort by anything you like. This does, of course, mean that you would have to create a mechanism to allow the user to select the sort order, generate the appropriate string and reconstruct the entire sql statement.
I had had a similar request quite a while ago. The underlying reason for that request turned out to be that the user just wanted to quickly locate records relating to one person. In the end, we agreed that a search filter was the best thing to do.

Andy

Tabular form with non base table field

I want to develop a tabular form with
1. A non-base table edit field to accept a value
2. Insert/update another table based on the input value
3. Also, computed field on each row based on other fields on the records (like post-query trigger in oracle forms at block level - for each row)
Thanks,
Rachna

Thanks for your reply.
Varad, I like the link you sent me. It has a lot of good information.
I created a process (under page processing) called "Update/Insert Process" that dosn't seem to be working.
Question, I created a manual tabular form with SQL Query and created a process (under page processing) called "Update/Insert Process", then I check for each record in the tabular form. If the old value <> new value then I update/insert in the new table.
Any step by step will be highly apprciated - to create process/validation etc.
Thanks,
Rachna

Tabular form - Different LOV for different rows

In a tabular form column, is it possible to have a select list whose values depend on some other column in the row? There doesn't appear to be a way to use #COL# notation to refer to current row values in the LOV query definition.
Ideas? Thanks

Hi Scott,
Thanks ..I formed some idea about APEX_UTIL.KEYVAL_NUM. I have a problem where I am not able to decide if I can make use of this package and solve..
Can you please have a look at this thread.. Re: Tabular form - Different LOV for different rows
I have a SQL which populates a tabular form on the page.Coulmn1 some text, Column 2 is to show a drop down as YES and NO. i am trying to freeze the option for rows 2,3,4 as NO, if the Option choosen in first is NO.
So, what I am trying to ask is..can I save my first selection in a global variable and use it in where clause of [select list query] the second drop down..Not sure how I can do this..Appreciate if you can show me a direction.
Thanks,
Chaitu.

ADD ROW in tabular form with new max value for a certain field

All,
I have a tabular form with an 'ADD ROW'-button.
When a row is added the field 'TemplateID' should get
automatically a new value which is MAX from TEMPLATEID + 1.
I would be very glad, if someone has a hint for me.
Thanks in advance,
lucio

Hi
the cause of not seeing the 'Default Item Field' is,
that during creation of a 'Tabular Form' the column with the
primary key doesn't get that feature, why so ever.
I still hope that someone could give me a hint why that code isn't working:
function SetNewID(vDBID)
v_check = $v('P20_MAX_TEMPLATEID');
pNd = $u_Carray(vDBID);
     for(var i=0;i<pNd.length;i++){
          var node = $x(pNd);
          node = $x_Check_For_Compound(pNd[i])
          var lTr = $x_UpTill(node,'TR');
updateRow = lTr.rowIndex - 1;
document.wwv_flow.f02[updateRow].value=$v(v_check)
Many thanks in advance
lucio

URGENT - Form with LOV - Query Fails

Hi All,
I've a portal form, with about 10 fields and about 06 of them are combo boxes (attached to dynamic LOVs).
I'm trying to perform a query using the ID and leaving all other fields blank, but no result is displayed. I am sure that the record for that ID exist in the database table.
Can someone please suggest what should I do to be able to perform query in form with LOVs.
Thanks in advance.

Hi Jatinder
I'm happy because you are apparently on the right way with 'your duplicate form'!
"adjust the empty values" means to make sure, that the value of the simple empty field (in the duplicate form) is the same as the value of the corresponding LOV based combo box field (in the original form).
Maybe this sounds easy, but in the matter of fact it isn't. Why?
Look carefully at the following sample:
You have a dynamic LOV based on the number column 'category' in your 'table_1'.
So the basic part of the LOVs query looks like this:
select distinct category from table_1;
Now you still have to add the 'empty value' to your LOV to complete your request to find any value of 'category'. But if you add '0' or ' ' (blank) it wouldn't work. So you have to add NULL but this still doesn't work because you have to adjust NULL to the corresponding data type.
Furthermore you have to be sure that the default LOV's value is the 'any value' one.
Your complete LOVs query then looks like this:
select distinct category from table_1
union
select to_number(null) from dual
order by category desc;
/* 'desc' for 'descending' ensures the NULL value to be on the top of the combo box */
Now as you know how it works for number columns simply use the analog logic for character columns with to_char(null) and for date columns with to_date(null).
That's it.
Thanks
Peter

Error tabular form with validation

Hi everyone,
I have built a tabular form with the wizard and I every time a validation check is done and fails,
getting an error in the place where the tabular form should be. I get to see the tabular form again when pressing the cancel button or refreshing the page.
I'm not quite able to reproduce this error, but I was wondering if anyone knows of this error and a workaround for it.
The error that's displayed is: report error: User-Defined exception
using Apex version 4.1.1. I've already tried building a new tabular form, but that didn't seem to resolve the issue.
I would appreciate the help.
Kind regards,
Cleopatra

Possible solution?
Validation returns : no data found + unhandled user-defined exception

Custom Tabular Form with working days by quarter

Hi All, I'm trying to create an application to improve an old excel that some people use in my office. I came across a challenge: create a page when a user can submit for each business day the amount of hours worked, the real problem is that I have to show on the same page 40 business days that need to be dynamic, I mean that there is a "period" table that has a start date and end date, the range between those two MINUS the Saturdays and Sundays should be the amount of COLUMNS that the report show.
create table CT_PERIOD(
PERIOD_ID VARCHAR2(6),
PERIOD_FY VARCHAR2(4),
PERIOD_QUARTER VARCHAR2(1),
PERIOD_START_DATE DATE,
PERIOD_END_DATE DATE,
PERIOD_DAY_COUNT NUMBER,
insert into ct_period values ('1', 'FY14', 'Q1', to_date('01-JUN-2013', 'DD-MON-YYYY'), to_date('25-AUG-2013', 'DD-MON-YYYY'), 56);
commit;
I searched in the web for some example of this with no luck, if somebody did something like this or knows where I can see an example that would be great!
Thanks!

Hi guys,
I'm having exactly the same problem, I need a tabular form with days as columns to add actual working hours for each day as for each row ( task)

Bug: 4.1.1 Tabular form with all columns conditional

I need to make all the columns in a tabular form conditional because in some situations the editable elements should not be shown. For some reason just changing the columns to conditional stops the form working, the ApplyMRU/ApplyMRD process runs but does not action the changed rows. I can't figure out why at all or any workaround.
You can easily reproduce this in 4.1.1 by creating a tabular form with the wizard selecting one column in the form. Then make the row selector colunn and your editable column conditional using the plsql expression 1=1. The form is displayed the just the same with these true conditions but it doesn't work. How weird is that?
Rod West

Rod,
In your scenario the tabular form rendering engine is unable to place the hidden, internal tabular form status columns in your form, i.e. the columns that contain checksums, etc. The logic that places these columns looks for the last unconditional, visible column in your tabular form, and includes the hidden fields there. So you need at least one column that's always shown for this to work. This can be an otherwise empty column. I filed a bug (#13881803) for this, so we can look into improving this logic.

Marc

Tabular form with onhover comment column

Hi guys!
I was wondering if anyone of you saw an example of onhover item help with query...I mean..lets imagine a tabular form with a text field Comment column. Comment column has width 50 but we all know that comment ale like to be long ;) I'd like to see full lenght comment every time I put my mouse pointer on a specific row. Is it possible ? If yes can you show me an example or point me in a good direciton...(I dont know javascript well..)
With regards,
PsmakR

PsmakR,
Yes it is possible. Currently the ShowPopup script displays the value of current cell (hv_item.value). You can just simply replace with whatever you like.
If you're talking about the value of other columns, you may have to use document.wwv_flow.fXX to refer to it. Again, see my other sample of [Tabular Form Column Read-only|http://apex.oracle.com/pls/otn/f?p=57043:4] . Patrick Wolf wrote about this as well in his [ Which Tabular Form Column is mapped to which Apex_Application.g_fxx array|http://www.inside-oracle-apex.com/which-tabular-form-column-is-mapped-to-which-apex_applicationg_fxx-array/] .

How to build a tabular form with a by the user insertable primary key

I have build a build a tabular form with the wizzard. Wat should I do to make the primary key insertable by the user.
When I change the PK from 'hidden' to 'text field', I get a checksum error when i am trying to insert.

Fred: When you use the tabular form wizard, notice the help text on the right hand side of each page. The help page where you define the type of primary key (Existing trigger, PL/SQL function, existing sequence) clearly states
Tabular forms do not support user entered primary key values
Makes sense when you think about it. The MRU process needs to determine whether to update a record or insert a new record. It does that by comparing the checksums (and/or) pk values from when the page was first rendered and then when you make changes and submit it. Newly inserted rows will have a blank PK/checksum.
If you allow user to change the PK, how will the system know which rows are new and which ones are old?
For example, lets say you have
create table t
pk int primary key,
data varchar2(10)
)You have 2 rows
1 red
2 yellow
If the PK were to be editable, user could go in and change the above to
2 red
1 yellow
Now what? Would you like the system to create a new row with 1/yellow or change the existing pk=1 row to yellow? Same with the other row.
Bottom line: The built-in processes dont support this. You can always write your own manual tabular form and implement whatever you logic you wish in your After Submit processes.
Hope this helps.

Select item on a Tabular form with a different dynamic LOV on each row

I would like to use a tabular form where one of the columns is a dynamic LOV based Select, and where that dynamic LOV refers to one of the column values on each row.
So if the tabular form represented a list of teams and the LOV-based Select column was the current team leader, I would want that select list to be populated only with the members of that team (different for each row). Since the list of team members is in some other table (all_players or something) I would want to populate the LOV with a query with a where clause that selected only those players records with a team-membership equal to the current tabular form's team id. So, on each row that select list's contents would be different.
-- Justin

I'm beating a dead horse here but I did get something to work with "less" code. My current needs do not require me to cascade drop downs, I only want 1. You can use the query like the in the first reply (but I don't have a table with joins) I created a simple two column table dept_emp with 4 records 10,null 20,null .... I want to fill the nulls with an employee but ONLY an employee that matches the dept. (Same concept of team leader and members).
Here's the query:
select apex_item.display_and_save(1,dept) dept,
apex_item.select_list_from_query(2, name, 'select ename from emp where deptno='||dept) name
from dept_emp
I removed the code that was there already (ApplyMRU) and just put in this code:
BEGIN
FOR i IN 1..HTMLDB_APPLICATION.G_F01.COUNT LOOP
UPDATE dept_emp
SET
name=HTMLDB_APPLICATION.G_F02(i)
WHERE dept=to_number(HTMLDB_APPLICATION.G_F01(i));
END LOOP;
END;
The G_F01 matches the column 1 and so forth. There's more documentation but little explanation at:
http://download.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25309/api.htm#sthref2171
The thing I could not get to work was a dynamic message
#MRU_COUNT# row(s) updated, #MRI_COUNT# row(s) inserted.
Not sure when the MRU_COUNT gets populated (probably in the routine I removed ;))
You're probably way past me by now but I like to have as little code as possible when it comes to maintaining an app. That's why I liked oracle forms so much. This kind of stuff was pretty easy to do.
Thanks again everybody!

ORA-01446 Tabular Form with CONNECT BY LEVEL =2

I created a tabular form where I would like the last 2 lines to be blank so the user can enter new rows immediately (e.g., the first time when no data is found).
The following is the sql for the tabular form:
select
"ID",
"REQ_ID",
"QUANTITY",
"FRAME_SIZE",
"FRAME_TYPE",
"PROTECTIVE_COVERING",
"MATT",
"MATT_COLOR"
from "#OWNER#"."CREATIVE_SVC_DESIGN_FRAMING"
union all
select
null id,
null req_id,
null quantity,
null frame_size,
null frame_type,
null protective_covering,
null matt,
null matt_color
from dual
connect by level <= 2 I get the following error:
failed to parse SQL query:
ORA-01446: cannot select ROWID from, or sample, a view with DISTINCT, GROUP BY, etc.
The query is not accessing ROWID from a view at all. And, as you can see, it is not using a DISTINCT, GROUP BY, etc..
My APEX is Application Express 4.0.2.00.07
My Database is 10g (10.2.0.5.0)
Please help!!

Robert,
I wish I had a better explanation for you, but I know something new with 4.1 broke this union trick for tabular forms. I had to make a dynamic action that runs on page load and calls the addRow() javascript function instead. I think it has something to do with tabular form validation but I am not sure.
Cheers,

Tabular form with editable items like Lov?

Hi everybody
I want to know if it's possible to make a tabular report / form where one column isn't a text field but a List of values. In other words, I'd like to edit the type of some columns of the tabular form, but in the Edit page doesn't appear a list of items like in the normal form pages.
Can you help me with this? I'm still a newbie with APEX!

I think you should read the manuals first. You can edit a report / tabular form and change
the type of the column - in the report attributes.
