Lov doubts

I have created lov with name country.In my form I have 11 item which storing country name.I created trigger key-listval in each item to display the lov.
I want to write common trigger or procedure to display the lov for all the item.
Thanks in advance.
Dev
Regards,

Please try this..
(Note tested- May give you astart)
Form Level KEY-LISTVAL trigger:
if get_item_property(:system.cursor_item,list) = 'TRUE' then
list_values;
else
message('No List attatched!');
end if;

Just got an 8 gig Zen MicroPhoto and love it! Just some suggestions tho

Hi everyone, my friend was considering a Zen Vision M and an Ipod video. I kinda suggested the Zen so he got it and absolutely loves it.
After seeing how nice the Zen Vision M is, I jumped on this MicroPhoto when I saw a sale and it is awesome!
The Zen MicroPhoto is a really good device, but just simple firmware stuff could make it a great one.
.) Ability to view pictures + listen to music
2.) Ability to view movies and video (the Muvo has smaller capacity and a screen with less colors and it can? Yet we are buying a nicer mp3 player than the Muvo but can't do video? The Sansa is small as hell and it can. It has the screen, hardware wise it should be able to do it, and if this is added through a firmware update, it won't be on the packaging and thus will not hurt sales of your other products.
I hate it when an awesome product is created and is capable of something and the manufacturer slashes that ability from it intentionally.
Another good example is the Gen III Ford Taurus SHO, its 3.4 liter Yamaha V8 was capable of revving well over 7500RPM and producing more than 30hp. Ford however, even though they had this jewel of an engine, intentionally cut its ability down to 235hp or else they feared it would be faster than their Mustang GT. What a shame, I hate to see that Creative is doing the same with the MicroPhoto.
3.) Ability to record FM with the latest firmware (If this is a RIAA issue, then please provide two firmwares and two download links, one that says "United States Users" and one that says "Non-US users"
4.) Ability to control different aspects of the glowing blue LEDs. They are obviously firmware controlled and can have brightness adjusted since they glow in and out when you have it plugged into the USB cable.
5.) Make it show up on your computer as a removable disk. On all my other MP3 players, it showed up just like a flash dri've and you could drag and drop whatever you wanted onto it, and it would just play whatever files on there it could play. Here, it won't let me drag and drop anything that is copy protected or is a different file type.
I know you can set aside 4 gigs of that for this purpose, but with the size of the files and videos I transfer, it would be nice if I could use all 8 gigs. Perhaps an option to just let the whole thing show up as a removable flash dri've?
*ok... I just tried it and that seems to be working on this computer that is Windows XP SP2 with WMP, but on the school computer that was XP SP2 with WMP0, it would not allow me to do this.

I think you will find that the reason the MicroPhoto is on sale is that it is now a legacy player (it was released before anybody could play video). I doubt very much that any further improvements will be coming....
EQ does have an effect... Maybe you earphones are not working well?

How can I solve LOV , TAB problem in Portal 3.0.6.6.5

Hi All,
I have certain doubts which i have summed up below. i hope you can explain/clarify me these doubts.
1) I have two lov in form one related to another.I clicked the first LOV (either combobox or popup) and inserted value in that field.When I am clicking second LOV (either combobox or
popup)it refreshes and inserts the result fine.IF I HAVE FIRST LOV WITH A DEFAULT VALUE AND IF I CLICK THE SECOND VALUE WITHOUT CHANGING THE FIRST LOV I AM GETTING ERROR.COULD YOU HELP ME IN THIS REGARD.
2)For updating a record in form I have to click the query and then update.Otherwise it is not updated.
3)whether it is possible to open a link which i specified in my report to open in the same portlet or i want in the new window not in the same window.is it Possible?
4)How to attach popup Date Picker script to my form field.
5)I have 3 levels of tab in my portel.In the third level I got report and form if i am
clicking the last tab i can't see the report i have to navigate the next tab in the last
level and come again to this tab to see the report.I don't know how to solve it
6)I got this type of link Report---> FORM for updating after form updation is over I have given back button to report.i want to refresh the report when I am in to the report.i have given refresh button now.But I have to do it automatically so I have written in body onLoad but the refresh is in loop so i can't see my report.So how i can solve this.
Thanks in Advance,
Sundar

I suspect this is failing on an UPDATE to the tt_03_reppeers table on Oracle. I would guess the TT repagent has to temporarily use serializable isolation when updating this table. Do you have any other datastores with AWT cachegroups propagating into the same Oracle database? Or can you identify if some other process is preventing the repagent from using serializable isolation? If you google ORA-08177 there seem to be ways out there to narrow down what's causing the contention.

How to change the values in an LOV based on values selected in another LOV

Hi,
I have a requirement in ADF where there are two LOVs. Based on the values that I select in the 1st LOV, the values in the second LOV should change dynamically.
Also, the 1st LOV accepts 3 values, for every value I select, a different query is executed to populate the 2nd LOV.
I have a rough thought that I can use 3 different read only view objects containing these 3 queries. And based on the value I select in the 1st LOV I can execute the corresponding View object from the backing bean. But my doubt is how to link the results of that query that is executed to populate the 2nd LOV.
Thanks in advance.

Hi Brisk,
Thanks for your reply.
The link that you have provided explains how to disable and enable the other LOVs based on a parent LOV. But in my case there are two Select One Choice fields i.e. the dropdowns (sorry that I addressed it as LOV in my previous post which might be confusing). There are 3 static values in the parent dropdown where each of them are associated with a different query. for e.g if the three values in the drop down are A, B and C; if i select A, then query associated to A should be executed ; if i select B, then query associated to B should be executed and if I select C, query associated to C should be executed. Then the output attribute of that query should be populated in the child dropdown.
Please let me know about the solutions to this.
Thanks,
Kavitha

Want to create a link on seeded page which can pass the values of LOVs

Hi,
I have a seeded page.. and i want to create a Link on the page which will redirect to new custom page...
When user clicks on the link, the values of some LOVs should be forwarded on the custom page......
I created a link through personalization... But I have doubt about how to attach the values of LOVs through url....
Is it possible to do the same???
Thanks in advance,
Kaushik

Thanks Pratap,
Yes the LOVs are created through personalization....
Since i dint want to touch the code... so i created everything through personalization.....
The only problem now is to get the values of these LOVs in URL....
Is there no other method other then extension to do this???
Thanks,
Kaushik

What we love, (and don't), about CS6

I am thrilled with the progress that Adobe developers have made with CS6. The control surface support and metronome were my "deal breakers" for CS5.5, but in CS6, there is alot more to love.   It has crashed on me once in the last three days... when I was adjusting an effects plugin on the fly.... but other than that, it seems very stable on my AMD 6 core system running 32 bit Windows 7 with 4G ram. I must say that the improvements over and above Audition 3.0 were significant enough for me to pay for the upgrade, even through full MIDI support is still on the horizon. It would be nice to have it, but it is not a big deal right now for the way that I prefer to work. I look forward to next editions, that are a bit more processor effecient (Audition 3 seems to play a large-scale multitrack configuration that CS6 will not. In fact, CS6 seems to handle fewer plugins at a time than its predecessor. No clue why this is.
I have even learned to live with the inability to change the tint of the user interface from various shades of sick brown to an almost metalic grey to death pallor, I have opted for the closest to flat metalic grey that I can get.... 3.0's ability to change UI color alowed me to make my visual display more appealing (at least to my admittedly quirky tastes).
All said, I am very happy with this software.   The control surface support is leagues ahead of the legacy cool edit support that was in 3.0.   Multiple control surfaces with android and ios devices working harmoniously together. This is the way that the control surface universe should be for bargain-seeking kludgers like me.
Keep up the good work. I was pleasantly surprised with the progress you are making on this.   I'm sure that many others must feel the same. Perhaps they too will express their gratitude to the Adobe Audition development team for their impressive work, and encouraging them to keep moving forward to an even more impressive CS7.
JPK
hmmm.. it says mark my discussion as a question. Perhaps the question is, "Why do you love about the new CS6, and what would make you love it even more?"

Claude,
One of the things that I love most about Adobe in general is the fact that they allow you to download fully functional, albeit time-limited, trial versions so that you don't have to have such fears. Simply download the trial version and follow the instructions.   They give you plenty of time to play with the software and decide if it is worth the investment.   If after the trial period you decide that the upgrade is not for you, e.g. because it won't loop, poop, or whatever bell or whistle you desire, you can choose to invest in another product that suits your needs. I doubt that the Adobe engineers will put up with bugs in their software, and I have faith that they will eventually address all of the functionality concerns, and perhaps even get to minor issues like being able to change the icky user interface color. It looks ok with earthy wallpapers, but it still makes me feel like I am sitting at the controls of a high-tech tank. Why, just awhile ago, I was mixing with Audition 6 and driving my tank through Stonehenge.
I knew for sure when I tried CS5.5 that it wasn't a viable upgrade for me after trying it.   It only took me a few days after I tried CS6 to make the decision to purchase an upgrade for one of my Audition licenses, mainly because the iPad and Android control surface app support was outstanding (i.e. multiple surfaces so no more bank switching, vu meters on the individual channels work, and the channel labels are no longer all screwy). Since I use Audition mainly to record and produce my own music and don't sequence or loop, the loss of MIDI functionality from 3.01 to 6.0 wasn't a big deal.   Since they do have the control surface support, and the control surface support operates via midi, I can't help but to think that such functionality will appear in subsequent versions of Audition.
I started out with Cool Edit Pro back in the '90s,   I stayed with it because when Adobe came out with Audition 1, they kept the overall layout of the user interface and made the pricing structure affordable, just as they have with version 5 in CS6.   The upgrade price from CS5.5 to CS6 is really reasonable, and if you already own CS5.5, I can't see a downside to going to CS6 (I was a beta tester for CS5.5, and ran it on a home-made hackintosh / windows dual boot system, with the goal in mind of getting away from Windows and eventually moving to Mac. I was impressed with the fact that the software was exactly the same in 32 bit OSX 10.5.9 as it was in 32 bit Windows, but the lack of control surface support made it not viable for me at that time). Now that I am running a stable and responsive 64 bit system with an overclocked processor, I have no need to move in the Mac direction at this time and dismantled the Hackintosh..   I have a feeling that the next version of Audition will have native 64 bit support, which should speed things up quite a bit. As it is, CS6 loads much faster than 3.01, and in my opinion, is much more stable than its predecessor.
Their engineers often respond directly and quickly to concerns raised in these forums.   No software is perfect. Audition is a fine product built by audio Software engineers in .a mostly visual work environment, and their relatively small development team has produced impressive results. Adobe could have dropped Audition altogether, and I believe almost did, because it is by far not its cash cow.   I for one am glad that they chose to hang in, and am grateful for the continued efforts of the developers, because I really didn't want to have to learn a new software package.
When I started this forum, I deliberately made it about what we loved first, and what we didn't second.   People derive more creative solutions when motivated by carrot rather than stick, so I encourage users to try the free trial download and give the engineers a fair and honest appraisal, beginning with feedback about the many things that these high;y capable engineers have gotten right. I am concerned that if there is too much customer dissatisfaction expressed, Adobe might abandon Audition altogether, or change its functionality so it is no longer that useful for people like me who use it as a complete music production solution.   Engineers have to answer to bottom-line oriented executives. We as customers ultimately decide the software's fate.   I for one hope that Adobe continues to move forward in its development.

How To Create an LOV in Jdeveloper 10.1.3.2.0

Hi,
Could anyone tell me as to how one can create an lov in this version of jdeveloper 10.1.3.2.0.
Thanks & Regards,
Madhur

Hi John,
Thanks for the detailed solution . Also i would like to clear some doubts.
Earlier i was using session.scope to pass value from one page to another. But since i have one jsp lov page and two fields 'from' & 'to' how would i be able to assign separate values when i am selecting them from same jsp lov page.
In other words how would i be able to reuse the jsp on other fields because if i change the values once it will be changes for all the fields.
one more query in the older version of jdeveloper 10.1.2.0 it was much easier to create an lov as u have options from the component pallete why have they removed it.?
Because i will have to create duplicate jsp pages if i have from & to fields for my search forms.
I hope i am able to get my problem through.
Thanks & Regards,
Madhur

Designing base VO for a page in create/update/view modes involving LOVs

Hi All,
We are developing a complete custom OAF page which is based on information in a single table.
The page will be used in create,update and view modes. 70% of the page fields are lov fields and hence I wanted to clarify my doubts before proceeding any further in development.
The page is based on a single table.
Example : XX_SUPPLIER_INFO(Columns : Supp_id,Supplier_trained_by_id,Service_manager_id,...etc).I created this as a EO based updateable VO
In the page "Supplier trained by" and "Service_manager" are LOV fields (messageLovInput style) that are based on plain SQL VOs.
Those LOV-VOs return displayable names and ids(key value) for those names and the IDs alone are stored in the base table(XX_SUPPLIER_INFO).
I am pretty sure of the above design will work for creation.
In update and view modes for the page will the lov field mapping help in automatically fetching the displayable names?
If not how should I design my Base page vo?
Any help on this is appreciated.
Thanks,
Haritha

Editing Oracle seeded files is not recommended as they are not upgrade/ patch safe. Read OTL impl white paper for your custom LOV requirements, They have explained well.

Can I have a LOV for display and a LOV for select values in a form ?

My LOV are in table :
lov_return, lov_display, lov_available
To avoid a loss in translating lov_return in lov_display values, I manage a flag, lov_available, Y/N to filter out obsoleted values.
By example, at the beginning of using the application, I have :
LOV_RETURN
LOV_DISPLAY
LOV_AVAILABLE
1
TOP
Y
2
CENTER
Y
3
BOTTOM
Y
And I have records with 1, 2 or 3 in the field corresponding with the LOV.
So far, so good.
Then I want to have a slightly different set of values in my LOV, for new records :
LOV_RETURN
LOV_DISPLAY
LOV_AVAILABLE
1
TOP
Y
2
CENTER
N
3
BOTTOM
Y
4
CENTER-TOP
Y
5
CENTER-BOTTOM
Y
So, when I edit an old record in my form, I want the 2 to be well deciphered into CENTER, and in the SELECT list, I want TOP,BOTTON,CENTER-TOP,CENTER-BOTTOM.
When I assign the dynamic LOV : select lov_display d,lov_return r from lov_table where lov_available = 'Y', to the corresponding field in my FORM, even allowing extra values will not help and will display '2' instead of 'CENTER'.
Is there a way I can manage to show the translated 'CENTER' in the field, and offer a list of values taking in account the 'availability' of the value, other than including the PX_FIELD test in my SQL for the dynamic LOV ?

A common logical problem I encountered back the days of Oracle Forms.
A solution I often see is displaying invalid options with an asterisk, and applying validation to ensure users don't change to invalid selection.
No doubt there are some clever ways to tart this up with jQuery, also.

Cascading LOV in a Tabular form

Hi Guys,
I have read numerous articles on the generation of cascading LOV's in a tabular form but havent been able to get it working
I have created an example in my apex workspace at:
http://apex.oracle.com/pls/apex/f?p=4000:1500
workspace XXAPPS
Username guest
Password demo
app no 17551
Page 2
In my test scenario, I have an emp table, dept table and an office table.
Within my tabular form(based on the emp table), I have a deptno column and an office column.
Depending on what the user selects in the deptno column, I would like the corresponding list of offices associated to that dept LOV to be returned in the offices LOV.
The table structure is
EMP
EMPNO
ENAME
JOB
MGR
HIREDATE
SAL
COMM
DEPTNO
OFFICE_ID
DEPT
DEPTNO
DNAME
LOC
OFFICE
OFFICE_ID
OFFICE_NAME
DEPTNO
When the user selects a deptno in the LOV I would like that to control the values that are returned in the office LOV.
I have used Jari's blog post:
http://dbswh.webhop.net/dbswh/f?p=BLOG:READ:0::::ARTICLE:2003800346210117
but as you can see it isn't quite working in that the office LOV is not returning anything.
I am pretty new new to JavaScript and jQuery so am no doubt doing something wrong as some of the steps are causing errors and are confusing me a bit e.g. step2 is causing the page to return blank (I have commented the code out in the example)
Any help would be greatly appreciated.
Thanks

Hi fac,
That is the full code as per the Jari's link on http://dbswh.webhop.net/dbswh/f?p=BLOG:READ:0::::ARTICLE:2003800346210117 (last but one section of instructions).
I have got the id of the elements (f07 and f06) by using IE Developer toolbar and have passed those into the dynamic action.
The child element is now just showing loading...
It seems to me that the on demand process is not being called because I changed the code to:
DECLARE
l_sql VARCHAR2(32700);
BEGIN
IF APEX_APPLICATION.G_x01 IS NOT NULL OR APEX_APPLICATION.G_x01 IS NULL
THEN raise_application_error(-20001,'code gets here');
l_sql := 'SELECT competency_id AS RET
,competency_description AS DIS
FROM XXMEL_FOCUS_COMPETENTCIES
WHERE competency_category_id = ' || APEX_APPLICATION.G_x01 || '
ORDER BY competency_description
APEX_UTIL.JSON_FROM_SQL(l_sql);
ELSE
HTP.prn('{"row":[]}');
END IF;
just to see if the code is getting to the process but the error message that I put in the PL/SQL is not firing.

Function to compare particular value with LOV Additional Description column

Hi,
Is there an existing function that compares a value with the "Additional Description" of a particular LOV ?
Can the comparison be done by "Adminstration - Personalization"?

Sorry & thanks sathish,
Now i got the result.
SQL> select DECISIONED_STAGE_ID,DECISIONED_STAGE_USER_ID from naap10_application where APP_DECISION_DATE BETWEEN TO_DATE ('31.01.2007 00:00:00', 'DD.MM.YYYY HH24:MI:SS') AND TO_DATE ('31.01.2007 23:59:59', 'DD.MM.YYYY HH24:MI:SS')
2 and application_id=2007010028552;
DECISIONED_STAGE_ID DECISIONED_STAG
2006060113 SYSTEM
================================
But one doubt,
When i created the column with the date datatype how it gets the time value,
And in one environment db i got the result but in another environment i dont get,
Shall i want to change any session status of date?

APEX 4: Cascading LOV generic?

Is it possible to have a "generic" cascading LOV?
I prefer to have my LOV as shared components (reuse and such) but with a cascading LOV the detail list refers to the Parent item within the query. This makes for a not very reusable LOV in my opinion.
Is it possible to use a more generic bind?
select description d, id r
from table
where parent = :B --<--- Not refering to any particular Page Item
order by 1... and specify the actual item which is to be used in the detail query? (Page Items to Submit)

Hi Learco,
I doubt that this will work, because the "Cascading LOV Parent Item" has to be a page item which is actually rendered into the HTML page. The reason is that for those page items we register a "change" event to trigger the refresh of the childs. If it's an application item it would not exist on the page.
I would also question if dealing with additional application items and additional dynamic actions would make the code better maintainable. If the LOV query is really that complicated that it would be beneficial to re-use it, I would suggest to define a database view for it and then again use a very simple LOV statement to access it. I think that would make it much more transparent and maintainable then trying some generic bind variables and placeholders.
Just my 2 cents
Patrick

Do i want to create a new Package for the LOV?Yes create BC4J component structure like xx.oracle.apps.xx.xx.lov.server and xx.oracle.apps.xx.xx.lov.webui.
For creating a LOV.
1. Create a item of Type MessageLovInputBean.
2. Create a LOV VO
3. Create a table Region inside it
4. Create LOV Mapping
Follow exercise : Search in below link to see how to create LOV.

LOV button in query mode

Why is an LOV button not shown when the block is in enter-query mode, but there is still an LOV available (using F9 button)?

This has already been filed as a Forms bug, no. 2179613 'EXTEND APP.UI.LOVBUTTONS TO ALLOW DISPLAY OF LOV IN ENTER-QUERY MODE'.
"Currently the facility to display LOV buttons automatically - the setting app.ui.lovButtons=true in the registry.dat file only works in data entry mode. It would be useful to be able to display the generated button in Enter query mode as well."
The priority is "Minor Error, No Loss of Service", so I doubt if this will be fixed soon.

Problem in LOV display length

i am facing a problem in a LOV display, one of the columns had a length of 4 earlier from the base table used in the LOV but after changing the base table to 10, actual column length is 5 but the fifth character is not showing in the LOV.
I hope, my question is clear. Please help in solving the doubt.
regards.

width=5 doesn't mean, that you see 5 characters !
e.g. you can see three "m" or you can see twelve "i" when using a non-proportional font
try to increase the size, so that you see enough
