LOV icon missing in query mode

Hi,
I'm using a LOV in query mode. But in Query mode the button with the 3 dots is missing. I can only enter the LOV by pressing CTRL+L. To improve the easy of use, I want to show the button in the text field (with LOV) as well. How can I realize this?
Regards,
Sten

I've changed the registry.dat file which I found on the middle tier in the folder
/u01/applmgr/rooscomn/java/oracle/forms/registry/
but without the desired result. When I switch in a form to query mode, there is still no button in the textfield (3 dots).
Thanks in advance!

LOV button in enter query mode

Hi
How do I show LOV button(Forms 9.0.2) in enter query mode?As of now LOV button is displayed only in the create mode.
Binod.

Hi Andrew,
Thanx for the reply. Actually I have not associated any trigger for this. Here Im refering the LOV button which comes inside the respective field(I mean we change the property lov_button to 'true in the regitry.dat). This button is not getting displayed in the enter query mode.
I hope now you are clear with the query.

How to display LOV on web in ENTER-QUERY mode with form or block query only.

Hello all
How can I display lov automatic on the web in from enter-query
mode in form or block query only mode.
thankx

If I understand correctly your explanation, your called form
fails to activate the LOV in enter-query mode when it is deployed
and test on the browser.
So lets proceeed like this, to make it work in all environments,
let us programetically activate the LOV.
HOW?
In the called form, write in the WHEN-NEW-ITEM-INSTANCE TRIGGER
at block level (if have more than one LOV)
IF :SYSTEM.MODE = 'ENTER-QUERY' THEN
IF get_item_property(:system.cursor_item,lov_name) IN ('YOUR
LOV1', 'LOV2' etc) THEN
IF SHOW_LOV(get_item_property(:system.cursor_item,lov_name))
THEN
NULL;
END IF;
END IF;
END IF;
The above code maybe tweak to suite your need and condition.
This way, we explicitly make the LOV appear in ENTER-QUERY mode
whenever the user clicks on an item with an attached LOV.
Hope this helps.

[Solved] Problem with LOV and 'enter query' mode

Hi all,
I'm kind of new to Forms and I'm having some problems that I'm not being able to resolve. I already search it on the net, but nothing relevant came up. If anyone could help me I appreciated it.
In my form I have some fields, and in one of them I have a LOV, and almost everything works fine. I inserted data, changed it, deleted it and all it's ok.
But when I change to 'enter query' mode, when I try to search for data on the LOV field it ignores what I write.
That is, for it, it's the same if I make F11 -> write 'aaaa' -> ctrl + F11 or if I make F11 -> '%' -> ctrl + F11.
It behaves the same way, shows me all the records.
Probably I'm missing something basic, but I'm not getting it...
Thanks,
Ana

when you create a lov by wizard the lov and record group have always the same name..
the problem is that the item is NOT based in the tabe.
what kind of query do you execute if you choose something from a love which is not based on the db?
i mean, this item has no influence on the query of the table, so whatever you choose it's like a "select * from table"
i hope i was clear

Disabling LOVs when not in enter query mode

hello. I currently have a form in which a master block populates a detail block. when the master is populated the cursor automatically goes to the detail block and sets it to enter query mode (due to the face that there are multiple details but the user may only view one at a time). To select the appropriate detail the user may select the detail from a LOV which is activated by clicking a button. once the detail has been selected and the query executed there is no real need for the LOV as the user can now edit/delete the detail. Also when adding a new detail there would be no need for the LOV as the presence of it would only confuse users. So basically the only time the LOV is usefull is during query mode to query the detail the user wants to edit/delete.
In your experiance how would you acheive this result?
Any help would be greatly appreciated.
Thanks

well you can write a trigger Key-listval on your LOV item to check the mode of the block
if :system.mode = 'ENTER-QUERY' then
list_values;
end if;LOV will only display in enter query mode only

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.

Showing LOV in query mode

Hi
How do you display a LOV using coding in a command button when the form is in query mode.

LOV in Query mode

Hi,
I have a form which when the user enters query mode, the user should be able to access the LOV attached to the 3 fields that are on the header level. On selection the values should be populated in the fields. The 3 fields are in a query only block.
If I use Show lov, and i make a selection, i get an error message saying that you cannot insert records.
Any thoughts ?

hai,
Its not possible.
Because the date control is actually a seperate block, and in Query mode, we cannot more to a separate block.

LOV in query mode (calendar)

Hello,
i know it's possible to enter in query mode and then select a value for quwey from a LOV.
but in case of a Calendar (date_lov.get_date(...) ) i got that 'Undefined control key... press Ctrl+K for a list of all keys'. something like this
why the LOV does not appear in this case? get_date is a procedure, contained in DATE_LOV package
so what i want is to enter in query mode and then call the calendar to choose a date as search criteria
Thanks

Query mode of Master Detail Form

I have a master-detail form.
I'm passing parameters to that form to autoquery data.
Everything works fine but "Next" button in a detail block.
I'm getting:
An unexpected error occurred: ORA-06502: PL/SQL: numeric or value error: NULL
index table key value (WWV-16016).
After autoquery LASTIN_SET variable of DEFAULT block is set "5" (number of rows in detail block).
When I click on "Next" button LASTIN_SET variable is set to "0" instead of "5" and that causes a problem.
So, somehow LASTIN_SET is not preserved between clicks.

What I'm missing here.
Aantoliy.

Say, I click on Update Push button. This will invoke a LOV that will occurs 5 times and then display the header and detail record.
Even if, I am able to get the records in the canvas, I am not able to update the records of the master. The record_status is in INSERT mode of the header block. Interestingly, if i click 2nd time on update button and then get the records after executing LOV, the query enters the query mode and I am able to update the records then.
Please suggest how to overcome the problem on a sigle click on UPDATE button.

Airplay Icon missing from iTunes 11.0.2.26 (PC) and Genius Sidebar

After upgrading to iTunes 11.0.2.26 my Airplay icon is missing. I've tried the simple fix that reportedly works where you switch to mini player, see the Airplay icon and then it stays when you switch to normal mode.
Firstly the icon does appear but it is grayed out and only pops up a volume control. It does not detect, display, or allow you to select output devices, Second, it is still missing from the normal size window.
This has been tried with and without restarting iTunes as well as reinstalling iTunes. I'd go for a downgrade but then it fails to work with the new iPads at all. I discovered that with my first iPad mini where it required an iTunes upgrade.
Genious Sidebar
I figured Id just downgrade to 10.6.3 to get the genius sidebar back afterwards. WRONG, it will not synch or do anything without the newer versions of the iTunes software. Genius sidebar was the best thing about the software and they kept taking it away, brought it back for a few versions, then took it away again. It was and remains my favorite way to shop for new music. The remaining so called genius functions are just plain lame.
Airplay Icon Missing from Itunes on PC
I can hit my Airplay devices such as Apple TV and Zeppelin Air with iPads, iPods, and iPhones. Just not from the PC Console where is previously enjoyed it the most. So I know the devices are fine. They are all on the same physical wired and wireless network. Even when I put the Zeppelin on the wired LAN there is no Airplay icon in iTunes on the PC.

Hi. just want to tell you i had the same problem Ipad--->tv working ok iphone---->tv also working ok pc home sharing not working and airplay icon in itunes 11.0.2.26 is missing. iam running windows 7 64bit
NOW! i can tell you in my case it was nothing to do with your router or antyvirus ip connection.
my pc is auto updating every sunday and icon has disappeared on monday i realized this fact and i have started uninstalling windows updates one by one after each uninstall i have restarted PC each time always run itunes and check if airplay icon is back. AND THER SHE WAS fiew windows updates uninstalled and icon is back in itunes
Now i can not remember what Update it was KB28 ..... something i didnt wright it down at the time i hope this will help someone.

What is the differences between viewCriteria query modes?

Hello all,
recently we faced a performance issue in a production application. after tracing we found that the issue was caused by setting the query mode of the view criteria to in memory.
bussiness case description:
when creating a new record for table A, I want to populate one field depending on records in another table B, so I used model driven LOV.
The problem was that new records were created for both tables in the same ADF train i.e. the data for both tables were not posted or committed yet.
so by using a query based ViewObject + viewCriteria with query mode set to memory for viewCriteria I managed to populate the LOV with the correct data,
in another page I will show database records for table A with LOV to show meaningful messages to users , but I can as well create new records for table A ,but the loading of this page is very slow.
tracing:
using alter session set sql_trace=true; I found that table B is fully scanned and all rows are fetched-180000+ record-.
Problem description:
from the trace file generated found that the query issued did not have a where clause.
also found that the viewObject fetched the entire table into memory- 180000+ record,- then searched them in memory.
Solution:
changing the query mode of the viewCriteria seems to solve the issue
so in order to avoid such issues in the future ,I wanted to make sure I understand the differences between the query modes of view criteria and their impact on the performance and if there are any differences if the viewObject is based on an entity or a sql dml.
this is what I know so far -please correct me if I am mistaken-:
1)database: search the database appending the conditions of the viewCriteria to whatever the query is
2)memory: search the rows that are already in the memory.
3)both: search both database and memory.
also, in case I updated one of the records in the memory but did not yet post or commit will the fetched rows have the updated values? and if these changes fails the condition from the viewCriteria , will the rows be shown?.

Hi,
When I click icon enter query on Oracle DEFAULT&SMARTBAR menu and then click icon execute query on Oracle DEFAULT&SMARTBAR menu, everything is OK.
But, if I put button, and trigger WHEN-BUTTON-PRESSED on it and command ENTER_QUERY in plsql code of this trigger, click the button and then click the second button to execute query with plsql command EXECUTE_QUERY - it doesn't work.
So I have two buttons:
1. button, WHEN-BUTTON-PRESSED trigger has command ENTER_QUERY
2. button, WHEN-BUTTON-PRESSED trigger has command EXECUTE_QUERY (this second command doesn't work)
Or: how can I programmatically execute command EXECUTE_QUERY when the block in is query mode?
thanks

Enter-Query Mode

I'm interested in starting a discussion on the restrictions of
Enter-Query Mode, principally, why can you not navigate to a
query only block whilst in this form mode? I have successfully
implemented an full Query functionality without using the
default forms behaviour, and wonder if there are any
disadvantages that I have overlooked.

Hi there,
Its quite involved, I have some documentation that goes some way
to describing the problem/solution, but briefly I find that when
in 'Enter-Query' mode (system.mode = 'ENTER-QUERY') there are
two restrictions
1) You cannot navigate to another block. This is useful in a
number of cases, like if you want to implement a more powerful
List of Values facility, or provide the user a seperate screen
to build up complex query criteria
2) If you write a trigger that uses 'enter_query' built in,
processing stops at this point. The standard workaround for this
is to start a timer before the call to 'enter_query', and when
the timer expires it performs the processing you want to do
after 'enter_query'.
So, I decided to rewrite the default forms enter/execute query
processing (which was pretty straightforward), so my forms never
go into 'Enter-Query' mode. What I am interested in is if there
is anything that using the default forms processing gives, that
I may have missed!

Set Query mode

hi all
i've a view object based on entity object . i use it as an lov for another object i want this lookup to retrive the data from both data bas and also cashed not posted data so i write code in the view object impl java class to override the method execute query and put some print statments to check if it's is executed but nothing is printed even though each time i open a select one choise based on this view it's execute sql statment
the code :
public void executeQuery() {
// this code is added to include the data in the cash
System.out.println("Here 2");
System.out.println("*************************");
setQueryMode(QUERY_MODE_SCAN_DATABASE_TABLES|QUERY_MODE_SCAN_VIEW_ROWS|QUERY_MODE_SCAN_ENTITY_ROWS);
super.executeQuery();
have any one idea how to solve this or make it another way ??

You are correct, the when-window-activated trigger will only work at the form level.
Your suggestion would work if the window in question was the initial window activated at form start up. However it is not the startup window. I am calling this window via a button from the startup window. When the button is activated I close my startup window (which is basically a menu window that takes the user to other windows based on the button they selected) and activate the window associated with the selected button.
So including the form level when-window-activated trigger as suggested causes both my selected startup window (set in the form properties) and the window I wish to be in query mode to launch...and I receive a FRM-41009: Function key not allowed error.

Jason
