LOV Auto Validation

JDeveloper Version - 11.1.1.4.0
Do we have an LOV Auto Validation feature similar to Oracle forms in ADF

Say I have an PetName field. And in my DB I have row values Cat, Dog, Parrot, Birds etc. So if I start typing 'C' in the PetName field, before I complete typing, 'Cat' should be populated in the field. I am not looking for an auto suggest behaviour where the values get listed down below the field. Instead the value should be populated in the field. This feature is there in Oracle forms as told to me by my colleague, and the same has to be implemented in ADF.

LOV Auto Validation Issue

Hi,
I have a LOV on Item Field,and the table has the Items ex: 8091,8091S.
User Enters the 8091 the LOV Window is automatically validating and finding the two results and poping up the window with results 8091 and 8091S.
actually what ever user entered is a correct value.how can i solve this issue , if there is a correct matching value in table it shouldn't open up the LOV window.
Thanks,
Indira

One Suggestion,
Make all the Lov mappins as 'Use for Validation' false. This shall make sure that the Lov does not fire when you enter a partial value. However the side effect would be that the Lov would loose its autocomplete validation features.
So you need to decide. If you make sure that the user shall always enter the correct value in the field (no validation done by Lov) the problem would be resolved. If the user selects from the list then also there is no issue. If you are willing to do some additional coding, I suggest you write your own validation method to validate the value entered by the user.
Hope the text helps.
Thanks

Problem in using LOV for validation-JHS 10.1.3

Hi all,
This problem was also noticed by Phil McDermott (Problem in using LOV for validation-JHS 10.1.3
I am following the demo and I noticed that the Use LOV for Validation functionality does not work on the browse page. However, it does work on the details page!
Another effect of this problem is that once you tried to validate on the browse screen, the lov button does not work anymore.
Thanks, Joep
Just found out that is does not work when entering "ph" like suggested in the tutorial. When I enter "p" and then tab to the next field, the lov popup does show.

Thanks for your reply Steven.
I had the same problem as Joep reported here, following the steps at:
http://www.oracle.com/technology/products/jdev/tips/muench/jhstutorial/index.html#genandrunagain
Your solution works for me.
The "completed version of the tutorial application" also has this issue:

Are there any other known issues for this tutorial? Where can I find such errata list?

Using LOV with Validation on the Numeric Fields results in Error

Dear JHeadstart Team,
During my work with lov I encountered another problem. I defined a lov and attached the lov to a numeric field and check the LOV for validation. Now when I use LOV using the LOV button it works fine but when I enter some numbers and then press tab the LOV was not shown correctly and resulted in the following errors and the worst thing is that you can not navigate to any other pages and all try to navigate to other pages results in errors too. When we put the same LOV on a string field (which is not desirable for us) it worked fine.
It seems to me like a bug. Am I right? Is ther any solution or workaround for this problem?
Thanks in advance,
Navid

Hi Navid,
We ran into the same bug and have the next workaround for it:
We extended the JHeadstart class 'LovItemBean' and we have overridden the method 'validateWithLov(...)' with:
public void validateWithLov(ValueChangeEvent valueChangeEvent)
    Object newValue = valueChangeEvent.getNewValue();
    if(newValue != null && !(newValue instanceof String))
      newValue = newValue.toString();
      ValueChangeEvent newEvent = new ValueChangeEvent(valueChangeEvent.getComponent(), valueChangeEvent.getOldValue(), newValue);
      newEvent.setPhaseId(valueChangeEvent.getPhaseId());
      super.validateWithLov(newEvent);
    else
      super.validateWithLov(valueChangeEvent);
}Next step is to use a custom template in your JHeaedstart Application Structure file for 'LOV_ITEM_BEAN'. In this custom template you should use your own class as 'managed-bean-class' instead of the default JHeadstart one.
Now you can safely generate LOV with validation of number fields.
Maybe something the JHeadstart can pcik up in the next release of JHeadstart :-)
Hope this helps.

Translation for OVS and auto-validation texts doesn't working.

Hello SDN!
There're two issues with translation.
First issue arised in OVS screen. I always get english text (I mean "Advanced search" and text for buttons) although my Webdynpro DC was created with russian language. Also only russian language set in browser. As I know it's impossible to change standart text in OVS but it could be displayed in other language.
Second issue arised in auto-validation. We have a node element which type came from dictionary of imported ARFC model. For example this type is a date. So when user entered invalid date (i.e. 30.02.2010), auto-validation processed and show error message that entered date has unappropriate format. Auto-validation is a great tool but error message displayed in english. But my requirements are that such messages of auto-validation must be displayed in russian language... Is it possible?

Hello there, Josiahfromvt.
Great job so far with troubleshooting the auto-brightness on your iPhone. After making sure you have backed up your device, you may want to use the following Knowledge Base article to setup the phone as new to test one last time:
Use iTunes to restore your iOS device to factory settings
http://support.apple.com/kb/ht1414
Once it is restored as new, you can review the steps found here:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/ts2802
Display doesn't adjust brightness automatically
The ambient light sensor brightens the display when using the iPhone in brightly lit environments, and dims the display in low light. To test this sensor, do the following:
If the iPhone is in a protective case, remove it from the case. If there is a protective film on the display, remove the film.
Verify that the Auto-Brightness setting (Settings > Brightness and Wallpaper) is set to ON, and that the Brightness level is set near the middle of the slider.
Press the Home button to return to the Home screen and then press the Sleep/Wake button to lock the iPhone.
In a bright environment, cover the top third of the iPhone to block the light, then press the Sleep/Wake button or the Home button to wake the phone. Slide the slider to unlock the phone.
Notice the brightness of the screen and application icons; they should be somewhat dimmed.
Remove the cover from the top of the display and in a few moments the display should get brighter.
My issue is still not resolved. What do I do next?
Contact Apple Support.
If you need to restore your device with your previous settings, the following article reviews how to restore from both iCloud or iTunes:

LOV auto-completion is not working (1)

When the user types in a partial value in the messageLovInput and tabs out, the value gets auto-completed if there is a unique match. If there is not unique match, then the LOV modal window opens up.
In some cases, you may see that typing in a partial value and tabbing out does not do anything, except for moving the focus on the base page. This can be because of the following reasons.
1. You may have explicitly turned off auto-completion, by specifying the value of property "Disable Validation" to true.
2. You may be using a browser that does not support PPR. Auto-completion relies on the PPR functionality, and it does not work in environments where PPR is not supported. For example, Netscape 4.75 does not support PPR. IE 6 and Mozilla 1.7 support PPR.

Try a reset and see if it fixes the problem. You will not lose any data.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

How to perform LOV auto completion

Hi,
I want to be able to leave the LOV text box empty and press tab to the LOV flashlight and the all the values corresponding to the LOV should appear automatically.
I have set Disable Validation --> False and Selective Search Criteria --> False.
So right now if i type in % in the textbox and press tab I am able to automatically get the list of values. But I want to accomplish this even without typing % in the textbox, i.e. leaving the text box blank.
Thanks

Even when you tab out of the LOV field from the base page, the LOV Window would pop-up. If you have the code that Ram, mentioned in the processRequest of your LOV Region's Controller, when the LOV Page opens up, the query will get executed and the results will appear....!
Hope this clarifies.

Should LOV be valid when beforming query ?

Dear All,
am using Jdeveloper 11.1.1.3 , and i have an jsf page (master detail ) and in that page user can enter new data or query for an existing data ,,
when entering a new data the LOV will bring u the data filtered on certain criteria ( lets say in case of employees ,the LOV should bring u only active employees ) , the problem occur when trying to perform query depending on a a value that is not in the LOV List ( lets say that i tried to query for a resigned employee) the page will give me : Error: Invalid value: 1000500160. when entering an invalid value in the input text ( emp no )
wish that am clear,
regards

but in the first approach i'll loose the validation that is fired while the insertion right?Yes, you will lose the validation performed by the LOV, but you can implement a "key-exist" validator at the Entity or Entity attribute level. (Our team never rely on the validation at the UI, we always define validators at the business components level, which is redundant sometimes). This validator will execute only in cases of real data entry and not when entering a query condition. In this way you will have reliable validation and the LOV will not fire unwanted error messages. The main disadvantage of an eventual removal of the <tt><f:validator></tt> tag is that if the user enters a partial value in the text field then the LOV will not automatically open and filter the possible choices.

LOV not validating from the list when tabbed out

Hi,
I have an item attached to an LOV generated dynamically based on another LOV. When I change the value in the parent LOV, and just click on the child item(which still has old value) and tab out, it does not validate from the list which has new values. The old value in the field is actually wrong one. However, it shows new values when I click on list of values for the child item.
I am also setting the property VALIDATE_FROM_LIST to PROPERTY_TRUE. The code to set_lov_property to the dynamic query is generic and is used by both key-listval and when-new-item-instance triggers. Except in key-listval I added list_values.
I am using forms 6i version.
Can any one tell me where I am doing wrong?
Thanks,

Neeraja,
Its because the item is not validating again, as there is no change in its contents. So you have to tell oracle to validate that item. For that in the WHEN_VALIDATE_ITEM trigger of the parent item, write,
SET_ITEM_PROPERTY('<block_name>.<child_item_name>', ITEM_IS_VALID, PROPERTY_FALSE);So when you tab out from the child item, the oracle will validate that item even if there is no change in the data.

Manu.

LOV Auto complete with controller class

Hi
I have two LOVs
i) Items Lov: Simple, no controller, VO and stright forward mappings. If I enter an item Description KB% and tabs on the column if there is only one record then the other mapped columns such as Segment1, Inv_item_id etc., are also filled up. This works perfect!
ii) Price List Lov: I have a controller set with this LOV to apply a filter criteria in VO. If I enter EM% in the price list description and press tab button and there is only one record I'm supposed to get other mapped columns such as Price List Id etc.,. But the Auto complete feature is not working so, I'm not getting other mapped values such as price list etc.,
Any body has any idea how to overcome this problem.
Thanks in advance
Prasad

Here is what our LOV expert has to say about this.
Open the LOV manually and try selecting a value and see if the results are returned properly. If it doesnot then there is something wrong with your metadata definition.
Your base page controller's processFormRequest will also be called when the values are returned from the LOV. Use pageContext.getLovResultValuesFromSession which will return a dictionary of what is returned from the LOV. Verify the dictionary by placing a breakpoint on this call in your processFormRequest.

LOV auto-reduction fearture problem

Hello,
I have a problem with the LOV when using other languages(not english or french), when typing characters in arabic language for example the auto-reduction feature does not work.
While it works very fine in english.
What should I do?
I've using Oracle forms 10g, application server 10g, java 1.6 update 4, windows XP, Server2003, Vista. IE 6 and 7
Thanks

If i understood your req. clearly, all you need to do is to base your database block query on value entered on a control block item.
i.e.
1) Create a control block and a field to enter value
This value entered will be used to filter records
in the database block
i.e. Not entering any value will query out all rows
from the base table block.
2) In the WHERE CLUASE of the base table block, modify
the where clause i.e. Use LIKE operator
WHERE databaseTable.ColumnName Like
:ControlBlock.FieldName || '%'

LOV Auto Refresh Issue - OAF Page

Hi,
Currently we are facing one issue with one OAF page.
We have one LOV in the page. Currently it is fetching the details as per the VO SELECT query associated with it and no issues in the query part.
But, if you try to update the tables which are associated to the above VO query, the updated results are not showing in the LOV even after re-login also.
One interesing thing is, we are able to get the updated results in the LOV once the server is bounced. Can any one pls let me know how to get this resolved and we are expecting this updated results needs to picked by LOV without bouncing the server.
Best Regards,
Hari

Hi Ankul,
We have already tried the approach which you have suggested. But still that did not worked.

LOV always auto-querying on second use

Hi,
I have an LOV with about 220,000 rows, so for obvious reasons, I've turned auto-query off (users must enter search criteria to use the LOV). This works great the first time someone populates a field in a multi-row table from the LOV, but the next time they use it, the LOV auto-queries all 220,000 rows. Am I doing something wrong? Is this a bug, and if so, is there a workaround?
Thanks much,
Avrom

Avrom,
We have fixed this for the upcoming release. You can apply a similar fix by creating a custom subclass of JhsDataAction for the Lov struts action, with the following code in it:
public void onQuickSearch(DataActionContext daContext)
HttpServletRequest request = daContext.getHttpServletRequest();
if ("true".equals(request.getAttribute(LOV_CHECK_FIND_MODE)))
return;
super.onQuickSearch(daContext);
