Disabling item in a tabular form - Urgent Issue!

I'm using Apex 3.0.
My tabular form has a text item with a following PL/SQL expression: TO_CHAR(:P44_DEFAULT_DATE,'YYYY/MM/DD'). When I either change the item type to "display - save state" or place "disabled=true" into its attribute or try to disable this item, using javascript, I get the following message on submitting changes:
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum= "23C7E42B598178DCEBF0D7FD89F22286", item checksum = "FD781F7254FF9A0F007587217EA02C6A"., update "REG"."TEAM_SALES_STAFF" set "TSS_ID" = :b1, "TEAM_ID" = :b2, "STAFF_NO" = :b3, "EXP_DATE" = :b4
Unable to process update.
How I can disable my pre-calculated effective_date field?
Sincerely,
Mike Mossiagin

Hi Mike,
You should use readonly="true" instead of disabled="true".
When you do "disabled", the value is not taken into account by APEX MRU.

How to refresh page after selecting value from LOV item , in a tabular form

Hi ,
I have a tabular form, which contains 2 items(columns), of type "Select List - named LoV".
Now, couple of issues here.
1.
2nd item(column) in tabular form, that LoV should get populated based user's selection value in first item LoV. So how do i refer to the value, that user selected in first item's LoV? I will have to use this reference in LoV query of my 2nd item ( on this tabular form)
2.
How can we refresh the page, when user selectes value in first item ( from LoV). As this is a tabular form, here item type is Select List, we dont have an option to pick item type as Select List with Submit. So problem is that when user selects value for item 1, refresh does not happen and item 2 LoV does not get populated as per user's selection in item 1.
Please help here. Would be really appreciated.
Thanks and Regards,
Rave.

Thanks Ben and Dan for your responses.
Ben, your solution helped me with refresh of page, as page got submitted.
This answers to my 2nd question. However, I still need to know first question, which basically is, how do i refer to the value, that user selected in first item LoV.
Issue is, I selected the value in first item LoV, it got submitted and page fot refreshed. But after page refresh, first item LoV loses its value that I had selected last time. It does not retain the selected value after refresh.
I have an unconditional process, that on every submit(refresh) of page, I set my items with their corresponding values. But problem is what do i mention there to refer to this item.
I looked in view source of my page, this item is referred as f03.
So i used "apex_application.g_f03", to set this item to its value, in my uncoditional submit process. But it did not work. I tried to refer this item as "f03" in this unconditional submit process. But still it did not help, the selected item loses its value after page refresh(submit).
Any help here would be really appreciated. Please suggest how do we refer to this item's selected value.
Thanks and Regards,
Ravi.

Disable columns in a tabular form on select list

I am trying to void out or disable certain columns based on the option value selected from the select list. I have done this on a form with regualr page items. However, I am now trying to accomplish the same on a tabular form. I have tried the following function and onChange event but it doesn't seem to be working. Any idea what could be wrong?
var htmldb_delete_message='"DELETE_CONFIRM_MSG"';
function Disable()
var sel = document.getElementById('f08_0001');
if (sel.options[sel.selectedIndex].value != '5' || sel.options[sel.selectedIndex].value != '7') {
document.getElementById("f04_0000").readOnly = true;
document.getElementById("f05_0000").readOnly = true;
} else {
document.getElementById("f04_0000").readOnly = false;
document.getElementById("f05_0000").readOnly = false;
THe onChange event : onChange="Disable()"

I've even gone ahead and tried th following code but still am having no luck
function Disable(pThis)
var currIndex = $('select[name="'+pThis.name+'"]').index(pThis);
if (pThis.value=='2') {
$('select[name="f04"]')[currIndex].disabled=true;
} else {
$('select[name="f04"]')[currIndex].disabled=false;
}

Update Hidden Item In Manual Tabular Form

Apex 3.2
I have a column in my tabular form which is used in an update.
APEX_ITEM.DISPLAY_AND_SAVE(34,f.qtyuser) oldqtyuser
I do not want the users to see this column, so on my edit report I unchecked the Show checkbox.
Now I get an error message and my update fails.
I have tried changing it to
APEX_ITEM.TEXT(34,f.qtyuser,10,6) oldqtyuser and unchecking the Show checkbox but still it fails.
I have tried changing it to
APEX_ITEM..HIDDEN(34,f.qtyuser) oldqtyuser and unchecking the Show checkbox but still it fails.
How do I achieve this
Gus
Edited by: Gus C on Nov 14, 2012 11:56 PM

Hi Gus,
Struggling to remember what is available in 3.2. What I did in this version was to append the hidden item to another item in the table. So for example if you have a text box in the table then use:
APEX_ITEM.TEXT(33,f.othercol,10,6)||APEX_ITEM.HIDDEN(34,f.qtyuser)
That way there is not extra column, but the hidden item is still displayed in the table.

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!

Can I disable Item object inside the Form

I have a couple Item derived objects inside Form. I don't want all of them to be selectable. Is there anyway I can do that - I don't seem to be able to find a correct API.
Cheers

Hello Sarah,
Yes, you can.
The Fluent UI is a static thing from its birth. You need to use callbacks to apply any UI changes dynamically. When required you need to call the
Invalidate or
InvalidateControl method of the IRibbonUI interface to get your callbacks invoked. You can read more about the Ribbon UI in the following series of articles in MSDN:
Customizing the 2007 Office Fluent Ribbon for Developers (Part 1 of 3)
Customizing the 2007 Office Fluent Ribbon for Developers (Part 2 of 3)
Customizing the 2007 Office Fluent Ribbon for Developers (Part 3 of 3)
Your callbacks may access the add-in class using the Global namespace available in VSTO based add-ins. When required you can call the Invalidate method to get your UI refreshed.

Returning multiple values from a called tabular form(performance issue)

I hope someone can help with this.
I have a form that calls another form to display a multiple column tabular list of values(needs to allow for user sorting so could not use a LOV).
The user selects one or more records from the list by using check boxes. In order to detect the records selected I loop through the block looking for boxes checked off and return those records to the calling form via a PL/SQL table.
The form displaying the tabular list loads quickly(about 5000 records in the base table). However when I select one or more values from the table and return back to the calling form, it takes a while(about 3-4 minutes) to return to the called form with the selected values.
I guess it is going through the block(all 5000 records) looking for boxes checked off and that is what is causing the noticeable pause.
Is this normal given the data volumes I have or are there any other perhaps better techniques or tricks I could use to improve performance. I am using Forms6i.
Sorry for being so long-winded and thanks in advance for any help.

Try writing to your PL/SQL table when the user selects (or remove when deselect) by usuing a when-checkbox-changed trigger. This will eliminate the need for you top loop through a block with 5000 records and should improve your performance.
I am not aware of any performance issues with PL/SQL tables in forms, but if you still have slow performance try using a shared record-group instead. I have used these in the past for exactly the same thing and had no performance problems.
Hope this helps,

Hi Guys
I want to Disable text field in Tabular form, Based on the Select List Item Value.
Let's Say
I'm having one select lista and text box in each record in tabular form.
Select List having 2 items ... Add Text(return value 1) and No Text(return value 2)
if value =1 then i want to enable text box , so user can enter value.
if value=2 then text box won't allow to add text or will become disalbe.
Please Help

Hi,
You can do this by using a small java script
<script language="JavaScript" type="text/javascript">

</script>Here P2_Text is the text box whose value I am enabling or disabling based on the selected value from a List box. On The list box I have onChange="javascript:FldEnableDisable(this.value)" ( You can specify this under HTML Form Element Attributes)

Help using a dynamic action to update tabular form items (specifically radio button) based on collection

Hi Everyone, I have posted this question in the past and made huge progress with Denes Kubicek's help: https://apex.oracle.com/pls/apex/f?p=31517:294:115851992029365::::: based on my earlier question posted: https://forums.oracle.com/forums/thread.jspa?threadID=2537494
I am struggling with one item in my tabular form. It is a radio button. The choices all appear properly, but the value is not saved in the collection (and hence, not saved in the table). All other items in the tabular form save properly.
here is what I have for the query.   It is item c024 (which maps to ;'f03'), which is defined as a radio LOV based on an existing LOV.
Currently I have:
2 page items:
P110_ID
P110_VALUE
Dynamic action called CHANGE COLUMN:

I have noticed the following:
when I change column C011 (price) the following values are set in the dynamic action:
P110_ID = f11_1
P110_VALUE = whatever I change the price to.
when I change the column C024 (hms_flag), the following values are set:
P110_ID = f03_0001
P110_VALUE = whatever I change hms_flag to.
the region is refreshed in my dynamic action, and the change for hms_flag does not hold. I have tested the SQL query that generates the value for v_SEQ in the dynamic action.   In both a change to price and HMS_FLAG it appears valid
select ltrim(substr(:p110_ID,5,4),'0') into v_seq from dual;
if f11_1, v_seq:= 1
if f03_0001, v_seq := 1
thank you!

solved. sort of.
field c024 references f03.
the Dynamic ACtion, step 4 calculates v_member by taking a substring of P110_ID...and in all other fields, the column and the field (fxx) are the same value....except for c024.
I am not certain exactly how to resolve, but see the problem.

How to retain value in LoV item in Tabular Form, after Page Refresh

Hi,
I have a tabular form, which contains 2 items(columns), of type "Select List - named LoV".
Now, 2nd item(column) in tabular form, that LoV should get populated based on user's selection value in first item LoV.
1. So how do I refer to the value, that user selected in first item's LoV? I will have to use this value as reference in LoV query of my 2nd item ( on this tabular form)
2. Everytime I select value in first item LoV, page gets refreshed, as my requirement is to calculate 2nd item's LoV based on selected value in first item. So after this page refresh, first item LoV loses its value that was selected before the page refresh happened. So how do i retain this value in first item LoV? I have an unconditional process, that on every submit(refresh) of page, I set all my items with their corresponding values. But problem is what do i mention there to refer to this first item ( of type LoV) of tabular form?
I looked in view source of my page, this item is referred as f03.
So i used "apex_application.g_f03", to set this item to its value, in my uncoditional submit process. But it did not work. I tried to refer this item as "f03" in this unconditional submit process. But still it did not help, the selected item loses its value after page refresh(submit).
Please help.
Thanks and Regards,
Ravi.

Hi Rave,
You will have to use Javascript and Ajax to change the values as ApEx submissions will lose your results unless they are saved into the database.
Remember, that as you are using a tabular form there will be lots of items called f01, fo2, fo3 etc on the page (one per row).

Two select lists in tabular form

I have two Select Lists which one of them depends on the another -the second one's query depends on the first one's - .....
This operation can be done in a form or a page, but how it could be done in a tabular form???
Saad

The simple answer is that to the best of my knowledge, it cannot be done because of how the tabular form works. If I understand it correctly, Tabular forms are populated completely at page load and cannot post back from items inside the form in order to refresh a list of values on the second select list. If you want to do this, you will need to build the form as a "Form and Report" page type where you have links in your report that populate a regular page form. Just tell it to put the form and the report on the same page them add a hidden page item that you set to 1 or 0 to display the form and setup the form processing so it is button tied instead of unconditional (You may have to duplicate auto processing processes).
The complex answer....there probably is a way to do this using AJAX as AJAX is good at this kind of stuff and every field in the tabular form has an HTML id of some kind....but I am not well versed enough in AJAX to give you a straight answer as to how to accomplish it. I used AJAX to do something similar to what your talking about but it was with regular page items (using a select list to populate a shuttle without a post back) and not items in a tabular form.

Tabular form on a huge view

Hello Experts,
I have implemented a tabular form on a huge view (about 300 million rows) in APEX 4.0. I then created custom items in the tabular form page for users to filter records and update them. The search would typically return few rows only. I have a instead of trigger for update on the view that will insert/update records to the appropriate table.
Now, when searcing a records and updating a record, the default MRU process seems to be going for a full table scan on the large table used in view. This is causing the page to hang and takes very long to update the row.
Please suggest a better way to implement this and to workaround the full table scan on the huge table. One option I am checking is to use APEX collections.
Thanks.

Hi,
without any details of your environment (OS, DB, Apex versions etc) and the query behind the view (SQL, explain plans etc), it is difficult to offer any information other than general guidelines. In short, the first things to do should be to treat this as a normal performance tuning exercise. Supply the required info and then the solution may be simpler than you think, possibly a simple rewrite of the query behind the view or maybe a new index, but until the info is supplied its impossible to say.

Andre
