Next element required when-validate-Item Triggers - navigational aid & key

Hello. I use historically when-validate-item triggers to validate the data entered in an item. If the validation logic fails, so I can "Raise Form_Trigger_Failure;" and the person should attempt to return a valid value before arriving at the order of the day.

However, in the form that I create now I need to validate the value entered and if it does not reach the validation logic, then I need to move the cursor to another element where they are required to enter into an explanation of the value, they came at the start. It is a big problem that I can not use 'go_item()' to a trigger "when-validate-item." Then I can just move the validation logic in a "next-key" trigger, either because the user could accidentally bypass the validation if logic they mouse out of the field rather than press the tab or enter keys.

How can I accomplish this? When my trigger "when-validate-item" fails while I still have to move the cursor to another element. Certainly there must be a way to solve this problem. Please let me know your thoughts. Thanks in advance.

Yes, you understand correctly. Only, don't code the validation in the trigger on validation, since built-ins restricted (as go_item navigation controls) are not allowed. Our forms are always the moment of validation of fixtures in a procedure known as the trigger of the validation key. Once the validation key trigger executes all changes (and they do not stop because of a Form_trigger_failure increase), it then issues a Commit_Form;

If you have a 'save' button or something similar that makes a commit_form, then his trigger when key pressed, just not a Do_Key ('Commit_Form'); Who will ensure that your key trigger - Commit and his appeal to your edit, will be carried out.

In addition, Andreas's suggestion above is good, too, although our forms don't do that. Only downside, is to create a completely separate and independent form.

WHEN-VALIDATE-ITEM triggers in a one-expected scenario

Hi all
I have a recording multiple field followed a checkbox for each record, where I have the trigger of the ORGANIZATION that actually changes the value of the checkbox on 'Y' when the field is changed manually.
Case 1: (Expected)
In this case, the existing value in the field is '-', now I replaced the field with the same value of 1, the VMI is triggered and box is enabled ('Y') indicating that this record is changed manually. .
Case 2:(Un-Expected)
In this case, the existing value in the field is '-', now I replaced the field with the same value '-', but still the VMI is triggered and check box is selected ('Y') indicating that this record is changed manually.
Please let me know if this is the real behavior of the ORGANIZATION.

Vicky,

It's actually expected behavior. Forms does not care if the value of previous and current are the same - he only cares that a value has been entered. If you want the VMI trigger only when the previous value is different from the current value, you will need to encode this check in your trigger of the ORGANIZATION with the help of the trigger of the item once - new - item - Instance (WNII). Something like the following example:

The following code examples assume that you have created the parameter of type CHAR PREV_VALUE object:
```
-- Sample When-New-Item-Instance trigger.
-- This trigger is needed to capture the value of the item before the user changes it.
BEGIN
     :PARAMETER.PREV_VALUE := NAME_IN('SYSTEM.TRIGGER_ITEM');
END;
```
```
-- Sample When-Validate-Item
BEGIN
     IF ( :PARAMETER.PREV_VALUE != :YOUR_BLOCK.YOUR_ITEM ) THEN
          -- The Previous Value is not the Same as the Current Value. User has changed the value.
          -- Do whatever validations need to occur here.
          ....
     ELSE
          -- Previous Value is the SAME as the Current Value
          -- Suggesting that the user typed in the same value in the field.
          -- Forms sees this as a change; which is why the WVI trigger is firing...
          NULL;
          -- NOTE: I would not normally code an ELSE where the instruction is NULL.
          -- I would just end the if statement (END IF;)
     END IF;
END;

Thank you all for any help,

After a second look at your code, it seems that you set just values for the detail-block IJT_INJ_PERS_TBL.

If you only assign values, there is no need for the GO_BLOCK. Just leave this line.

BTW... When you refer to blockitems, you must use the BLOCK. POINT as
```
:IJT_INJ_PERS_TBL.badge_number       :=  v_badge_number;
:IJT_INJ_PERS_TBL.last_name          :=  v_lname;
:IJT_INJ_PERS_TBL.first_name         :=  v_fname;
:IJT_INJ_PERS_TBL.middle_initial     :=  v_mid;
:IJT_INJ_PERS_TBL.ssan               :=  v_ssn;
:IJT_INJ_PERS_TBL.dob                :=  v_dob;
:IJT_INJ_PERS_TBL.job_title          :=  v_title;
:IJT_INJ_PERS_TBL.shop               :=  v_shop;
:IJT_INJ_PERS_TBL.shift              :=  v_shift;

Filling of the elements in another block in when-validate-item
When the user changes the value in the given field, I need to insert records into different blocks. The second block is block of multi-record. The two blocks are no db block, just for display. When the value is changed by the user to the first block, calculating product collecton who wish to view the content of each element in the second record to display block. The problem is that I can not enter the values for records in the second block other than the first record. To access the second records block display, need to navigate to display block with go_block and navigate to new records with next_record. Both go_block and next_record cannot be called from the Organization in the form of small modules.

I want to avoid having to press the button that makes a new calculation and redisplay (so can use go_block and next_record), wish just to refresh when the user updates the value, IE the Organization
You can use WHEN-VALIDATE-ITEM trigger to loop through the record of the block in detail using the TIMER. What you have to do is in the trigger WHEN-VALIDATE-ITEM create timer like below...
```
TRIGGER = WHEN-VALIDATE-ITEM
DECLARE
  vTimer TIMER;
BEGIN
  vTimer:=CREATE_TIMER('MY_TIMER',10,NO_REPEAT);
END;
```
Now, create a trigger more on called WHEN-TIMER-EXPIRED at the form level and use the code below...
```
TRIGGER = WHEN-TIMER-EXPIRED
BEGIN
  GO_BLOCK('DETAIL_BLOCK');
  FIRST_RECORD;
  LOOP
   -- Perform your functionality here...
   IF :SYSTEM.LAST_RECORD = 'TRUE' THEN
     EXIT;
   END IF;
   NEXT_RECORD;
  END LOOP;
END;
```

Dilemma when-validate-Item and Go_Block/Execute Query
Hey people out there - probably not a matter of surprise on this forum. I have tried to look for it and came up with a few posts but did not find solutions. If all goes well, I also did the right way to conduct a search on this forum. If this is a message for the umpteenth time on this question, I apologize.

So, I have 2 blocks:
1. the block command that contains the field STUDENT_ID (database item = 'n')
2 block database which contains STUDENT_ID field (element of database = 'Y' and many other areas)

My goal is to do an Execute_Query if the user enters the student card, then press TAB or place the MOUSE in the database block and display the record if it exists. As we know, a Go_Block is not allowed in When-validate-Item. So, I went a little more away from "simulate" this. The problem is that I'm always pulled the query Execute when the record has already been retrieved. Here's what I have so far. Thus, the trigger next-item key works fine if the user types a tab of the student card and presses. It also works very well if the user clicks on the STUDENT_BK as the trigger once - new - block - Instance that triggers calls the next key. The problem occurs when after recording was recovered and the user click on control.student_id then comes and clicks on the STUDENT_BK, the KEY NEXT-ITEM trigger fires again.

Suggestions or pointers would be more than welcome.

Thank you!

CONTROL.student_id. Next-key
```
  if :control.student_id is not null and :SYSTEM.BLOCK_STATUS != 'CHANGED' then
    next_block;
    clear_block(NO_COMMIT);
    execute_query;
  else
    show_alert('Please enter Student ID');
  end if;
```
STUDENT_BK. Once - new - block - Forum
```
go_item('control.student_id');
do_key('next_item');
```
I think you remove the "value copy of the element" and add a where clause clause to your STUDENT_BK of "student_id =: CONTROL.» STUDENT_ID.

Then when you do
```
if STUDENT_BK.STUDENT_ID != :CONTROL.STUDENT_ID then
```
It logic should endeavour to answer your second question mark block requirement when the user between the block of database STUDENT_BK. If the IDS match, the record already was questioned, if this is not the logic of your application is triggered and with the where clause added to your STUDENT_BK block, it would be in the folder that you want to.

Go_Item not available in a when-validate-Item trigger function
Hello. I find that I can't use the Go_Item function in a trigger when-validate-point because it's a small trigger. Is there a common method to pull a trigger that I can use to validate an element (similar to the trigger when-validate-point) is not restricted to where I can use built-ins such as Go_Item, Go_Block, etc... I would use the trigger next-item key, but it does not when a user mouse clicks outside of the question, I need to validate.

I need to get a validation on an element that identifies if some values were seized. If I find some values, so I need navigate a block "Diary problems" where the user can complete a problem. After leaving the block "Issues Log" I need then to return to the previous box and allow the user continue to enter items. This navigation appear to be limited in the when-validate-Item trigger.

Any help would be greatly appreciated.
Yes as Frane explained to create a timer and the fire on WHEN-VALIDATE-item and it expires after your operation as workaround

or at the level of the blocks ONCE - NEW - ITEM - INSTANCE, you can write something similar
```
  if :system.trigger_item = 'MYBLOCK.MYITEM' then
         Your code
 end if;
```

Values to change due When-validate-item trigger
Hello

I develop a Form6i. I have a lov client_name field. I have a when-validate-item trigger for the customer name field.
When I select the cutomer_name I have other fields who shoot according to the client_name as payment_term, Sales_rep, price list and so on.

The question I have is Ex:

When I select client_name = "ABCD". Field of payment term will be driven using the code of a trigger when_validate_item and complete payment limit = 45 Net.
When I change the payment term is Net 30 and save the form, it will return to Net 45 and saves.
I know it's because when-validate-trigger fire again at the form level.

I want to change the payment_term to change only when client_name y change. Like the same functionality as Oracle, order entry

How do I have more to come, can someone help please.

Thank you.

Restricted procedure illegal GO_BLOCK in WHEN-VALIDATE-ITEM trigger.
Hi people!
There is more than one type of best practices of the question. I use Forms 6i and encounter the above error at any time. It seems that it is true very convenient to an another datablock and loop to validate a particular field. I end up creating a cursor to restore the logic which has already been built in the block. Does anyone know an easier work around? Thank you!
The idea makes sense, but navigating to the other blocks (and even the other rows in the same block) is not allowed in a trigger validation. This is one of those strict rules Oracle Forms.

Question about integrated NEXT_RECORD and when-validate-point trigger
Hello

I work with a form that/did the following:

1) has two blocks of data (block 1 - & gt; Simple registration block & Block 2 - & gt; Block Record multi)
2) has few items in each block.
(3) when I filled the block 1 fields and press tab to navigate to next item key of an element in the trigger in block 1, block 2, I created a timer and when the period expires, the When-Timer-Expired trigger in the form of fires, which has a cursor that retrieves data from different database tables and assigns to the items in block 2 and saving the form must Save all records to the database tables attached to form blocks.

During this process when I open the cursor and assign values to each element and say NEXT_RECORD when-validate-point triggers written on each level elements fires and validations. The code looks like this.

Code of the trigger WHEN-TIMER-EXPIRED

DECLARE
CURSOR C1
IS
................
................
................
BEGIN
FOR c1_rec in C1
LOOP
: block2.item1: = c1_rec.col1;
: block2.item2: = c1_rec.col2;
: block2.item3: = c1_rec.col3;
message ("point value 3 is" |: block2.item3);

NEXT_RECORD;
END LOOP;

DELETE_RECORD;
POST;
PREMIER_ENREGISTREMENT;
END;

So my problem is the value assigned to: block.item3 before call NEXT_RECORD is away for WHEN-VALIDATE-ITEM trigger on the same element. I tried to print the value as soon as the trigger is activated. Assume that the previous value is "100" the WVI trigger value is printed with a NULL value.

I tried several times, but all the time, I get the same value.

Can someone help me identify the problem?

Thanks for your time and help
Your problem may be a timing problem caused by a trigger when-validate-order of the day on your null file at the end change your loop like this:
```
FOR c1_rec in C1 LOOP
  If :System.Record_status <> 'NEW' then
    Next_record;  --only advance if record is already populated
  End if;
  :block2.item1 := c1_rec.col1;
  :block2.item2 := c1_rec.col2;
  :block2.item3 := c1_rec.col3;
  message ('Value of item 3 is ' || :block2.item3 ||', Value in Col3='||c1_rec.col3);
  message(' ',no_acknowledge); --force above message to display immediately
END LOOP;
POST;
```
In addition, you must not use next-element key to start a clock. What happens if the user clicks on the element rather than the tab? You should start the timer of the trigger when-validate-record of the first block. It runs all focus time leaves the line of Block_1, unless a change has been made, and regardless of how the user leaves the line.

I have a field called equip_code and some validations on the when-validate-item trigger that fills some years messages then opens a comment box. Next to this piece of code equip, I have a button for the list of values. If the user clicks the button (LOV), I have this code.

If FORM_SUCCESS then
do_key ('LIST_VALUES');
end if;

How can I force the trigger when-validate-point once the user chooses in a list of values.

Next key element I have this code

Validate (item_scope);
If form_failure then
raise form_trigger_failure;
end if;
do_key ('enter');

I have this so that when-validate-item trigger before button-next. But when the user chooses in a list of values, I want to trigger when-validate-point. Any help appreciated.
Your LOV button, in relaxation when button pressed, just do this:

Go_item('MY_BLOCK.) EQUIP_CODE');
If Form_Success then
List_Values;
End if;

I don't think that anything on the trigger next-item key you need. If the equip_code value is changed, the WVI trigger runs when the focus (the slider) leaves the field.

If you want to force the validation immediately once the user selects a value from the LOV, you can then change the List_Values; call over Do_key ('LIST_VALUES'); then create a trigger key-ListVal on the element. In the code, you d code: If Show_LOV ('MY_LOV') then Validate (Item_Scope);

You must NOT put the code of validation in the trigger element next key, because it does not work if the user uses the mouse to click in a different field, or that he uses any number of other methods to leave the field.

return to the step after when-validate-point raise form_trigger_failure
Sorry for this question but its a long time I had to program forms...

I do validation step in a when-validate-point trigger. the trigger fires form_tirgger_failure on the validation point failure.

is there an easy way to make the focus to the item once the failure is triggered?

the most insight.
You don't have to do anything. When form_tirgger_failure raised in when-validate-item, navigation fails and that the focus remains on the original item.
Is it not what you see?
