Selecting hierarchical LOV

Somewhere in your pageDef, you probably attribute definition where you fix LOV, in the form of:

(if you do not have the case, add a)

Then, for your af:selectOneChoice, just give the value property, which designates the attribute in pageDef, value = "#{bindings." SomeId.inputValue}'

Display data in Table a selection of LOV
 
			 
Hi all
I have a scenario in which the JSF pages contains a LOV and table of the ADF.
My requirement is to display the rows in the table based on the value selected in LOV.
The table and the LOV were built out of same data control.
I use Jdeveloper - 11.1.2.4.39.64.36.1 version.
Tips gently on the way forward.
Best regards

Selection of LOV tabular
 
			 Hi guys,.
My version of the form is Forms [32 bit] Version 10.1.2.0.2


OK, now I should like to inform the problem. I have a tabular presentation where I used LOV to select the different ITEMS. When I select the LOV in 1st row to select the ITEM... then my concern is not to display it in the following line of this LOV ELEMENT on which I have already selected for the 1st. I want to reduce the QUESTION on the fly.


If you have any solution for this problem, please let us know.

Short: I want to select components in ultiboard, which belongs to a specific hierarchical block in multisim. Secondary attribute to a group of party in ultiboard.
Best show a column in the list parts view with the hb_sc_name property already contained in the file .ewnet for each instance of the component and allow sorting by this column. Then you can easily select all parts with a specific hb_sc_name and change their "party group.
Or something similar.
			 
Hi tfa.
You can do it, but only from Multisim. It also will not work in Multisim 10.1 and earlier versions, because part groups (also part spacing, pin swap and Exchange door) where no specific instance as they are now.
In Multisim, open the main design and select the hierarchical block that you want to change.
In worksheet view, select the components tab
Make sure show all is not selected
Click the column heading of the Group of the party to select the entire column
Select one of the items, and change the name
NOTE: when you select the item, you must select a component that can be a part of the Group (for example, by selecting a HB/SC connector, you cannot change the name of party group).
		   
 
            
           
 
		     
Handling cascading LOV (multi-Select parantes LOV)
 
			 Hello


I use LOV cascade.


P1_PARENT - Parent LOV (i.e. multiple selection)
P1_CHILD - child LOV


LOV Parent being multiple selection, so it will have the following values... P1_PARENT = AA:BB:CC


and where clause in the LOV cascading should be like
       where col1 in (:P1_PARENT)
   
-How to convert the element value for P1_PARENT of AA:BB:CC to "AA", "BB", "CC"
- Is there an another way manage in cascade LOV (to select several parent LOV).


Select the list of P1_CHILD
 
    select d, r
  from test
 where col1 = :P1_PARENT
 where col1 in (:P1_PARENT)
Thank you
Deepak			 
Hi Deepak,
In where clause for the LOV child, you can use instr function as:
(instr(':'||:P1_PARENT||':',':'||col1||':',1) > 0 ) 

To access the individual elements in the multiple selection: P1_PARENT, you can use:
DECLARE

l_selected HTMLDB_APPLICATION_GLOBAL.VC_ARR2;

BEGIN

  l_selected := HTMLDB_UTIL.STRING_TO_TABLE(:P1_PARENT);
  FOR i IN 1..l_selected.count
  LOOP
        //  your code here...access individual elements using  l_selected(i)
  END LOOP;

END;

Thank you

Loading list select cascade lov
 
			 I have three selection list each with a parent lov cascade, except the first.


1 - TOOL
2 - CATEGORY
2. - IN SUBCATEGORY


Of these 3 elements of selection list... what I save is the "return value" of the subcategory, which is an identifier. If the problem appears when I try to change the information after I save it. I tried to extract the information in the "source type" box with an "sql return value" as well as the sector 'default value', but he did show errors when I want to create a new record... So I wonder if I can bring data with javascript or otherwise... Thank you


Best regards, bernardo			 
Hello Bernardo.
the problem on your page 3 is that P3_CATEGORY is not automatically by a column of data. That's why when you view an existing record he won't show anything. And because the value is NULL, your 3rd LOV (P3_CATEGORY_ID) won't find something because P3_CATEGORY is null or an invalid value.
You have two options:
(1) add the CATEGORY in the database column to your table of PROBLEMS or
(2) use a calculation or process to extract the CATEGORY based on your subcategory (P3_CATEGORY_ID) and fill P3_CATEGORY with this value. This calculation/process to trigger after the process of "fetch".
See my calculation of example on page 3. In addition I also put P3_TOOL as "Page to go" for P3_CATEGORY_ID LOV, because you always have to specify all the columns that are used in the SQL statement 'Cascading LOV Parent éléments' or 'Page to present '.
Hope that gives you a direction.
Concerning
Patrick

How to submit a page to select an LOV?
 
			 Hello


I'm looking to create a parameterized report very similar, but even more simple than that in Chapter 3 of the book advanced tutorials.


It would be simpler, because there would be a single LOV in the form region.
That's why I try to get rid of this button in the form this region. In other words, as soon as the user selects a value from the LOV, the page must be sent automatically and data in the report area must reflect the change in setting.


How can I do this?


Thank you very much


Gabor			 
Prior to version 4, simply choose the option 'list with submit selection' when you set your LOV.
In version 4, choose 'Select list' and then further down the page under "Settings" choose the option 'send page' the ' page when the changed value.
		   
 
            
           
 
		     
Report master-detail or list popup selection on LOV
 
			 Master/detail report
Using Popup LOV of a column in DETAIL. Why the RETURN_VAUE displays rather than the DISPLAY_VALUE? I need to display ITEMNO. It sounds like a problem with a tabular presentation?


LOV is
select ITEMNO display_value, ITEM_ID return_value
 from SH_ITEM
 ORDER BY 1
Table
*SH_ITEM*
ITEM_ID
ITEMNO
ITEM_DESC
Is actually long version that I really want
select ITEMNO || ' - ' || ITEM_DESC display_value, ITEM_ID return_value
 from SH_ITEM
 ORDER BY 1
Published by: userRRRYB on July 2, 2010 07:06			 
Hi Alexandra,.
In APEX 4.0, Popup LOV key support has been added to the built-in tabular feature (named for and based query LOVs), so now you can view the DISPLAY_VALUE according to needs. LOV Popup displays only the RETURN_VALUE, as you said, so it will not be your needs, but the new Popup LOV key should do the trick for you. If you change the attributes of a column in a table, update the column in question to the value of the point of his ' display as ' Popup LOV key (named LOV) or Popup LOV (query based LOV) key.
Kind regards

changes in the value of the text depending on whether you select value LOV
 
			 for example, I have this list angoua, graig, manu... I select Clément... then a text will get a value such as "person" wrong or anything like that, I would like to put in an IF statement in accordance with the selected value of LOV			 
Hello
It's not good to treat angoua as a person wrong ;)
You can write this code of the trigger KEY-LISTVAL of the element. assign the value to a piece of text in the trigger KEY-LISTVAL and LOV, make sure that the value and write the code accordingly.
Kind regards

I go back to sch_id which is a list of number type selection (3.0). The LOV selection list has the following attributes:


Display extra value: No
Dynamic Translation: No
Number of Columns: 1
Display Null: Yes
Null Display Value: blank

Here's the code for the LOV:
SELECT distinct(site_id || ' - ' || initcap(lower(site_name))) site_desc, site_id ret_val
FROM sa.SITE_DEMOGRAPHICS@sis
order by 2
I don't know why I kept ORA-01722: invalid number during the presentation of the page. Everyone ran through this issue?			 
Hello
First of all, you should also use nv ('itemname') for numeric values-, make sure you use v() instead of V() for others.
If the p50100_sch_id can be null, the return value will be "null %" - which could be the cause of the error.
In such cases, I tend to do something like -1 of the value zero, then do a test for that, in the code - if the value is - 1, I replace NULL

How to get the value in LIB in selection of LOV
 
			 I have the designer generated form. Most of the logic is processed in Library.I do something about validation in £ QMS under Event_name = "key_commit." I have a LOV having the value 1. 2 current. unknown 3. recorded and coresponding parameter system CU, United Nations, RE respectively that return the value in the form field. Now, in the validation, I have to check if the status is 'current' and end_date don't thats not null then we should not allow to save the file and send the message. Keep in mind that I do in the library only if you guys tell me how I will get the value of LOV being selected and get it in / or provide library to comapare against the value of the system setting that is in the database
-Check if there is an end date, but the status is still defined as 'current '.
IF NAME_IN('RCBADG.) END_DATE ') IS NOT NULL THEN
-Do the system_parameter_identifier for the entry labeled as "CURR.
- AND the user set the value of the parameter (code for 'Current')
Select parameter_value
in v_par_value
of system_parameters
where cspara_identifier =(select identifier)
of coded_system_parameters
where code = 'CURR');
-Get the identifier of status register coded for "CURR.
Begin
Select the identifier
in v_crsta_id
of coded_register_statuses
where code = substr (v_par_value, 1, 4);
EXCEPTION
When no_data_found then
v_crsta_id: = null;
End;

-Check if the status of "Current" is defined
IF v_crsta_id = v_crsta_id1 then
-v_crsta_id1 is drive where the value must be equal to system param 'CU' LOV selection
QMS$ SHOW_MESSAGE('SSL-15008','E',TRUE);
RAISE FORM_TRIGGER_FAILURE;
ON THE OTHER
null;
END IF;
END IF;			 
I can only imagine that I have no idea what makes your library in detail.
The event that you would get would be the WHEN-VALIDATE-RECORD (at least that's the trigger I would implement the logic).
With respect to the verification of the value and the end date. I guess the Lov will return the value selected in some element in the block, then the comparison would be something like
IF NAME_IN('RCBADG.END_DATE') IS NOT NULL THEN
  IF NAME_IN('RCBADG.THE_ITEM_WHERE_THE_LOV_VALUE_IS_TRANSFERED_TO')='CU' THEN
    -- Show some error here
    ERRoR
    RAISE FORM_TRIGGER_FAILURE;
  END IF;
END IF;
		   
 
            
           
 
		     
Select list (LOV)
 
			 Hello
Is it possible to display a blank for a list of value? It currently displays a % sign when I only want to show an empty value? I activated the value "Null display" but did not specify a 'display value Null. How to display only one value blank or empty? Do not want to specify a "display Null value.


Thank you			 
Hello
Entered a character space in 'Value Null to display' will do the trick (but typically something like - select a value--is easier to apply).

How to return a query all the elements for an LOV if I select the "white point" (in this LOV)
 
			 
Hello. In my application, I have a classic report where, in a region, I built a toolbar with three Popup LOVs which interact with the report. Each LOV displays different items and returns the value according to the selected item.
For example:
Popup LOV 1 named P33_DEPARTMENTS has the following components: production, development, projecting, ecc.
Popup LOV 2 named P33_LOCATIONS was the following: Europe, America, Asia, Africa, ecc.

Popup LOV 3 named P33_DEVICES has the following: printer, keyboard, mouse, monitor, ecc.

If I query the table to return the lines according to the selected in these LOVs I have something like this:

SELECT * FROM < table > WHERE the dep =:  P33_DEPARTMENTS AND loc =:  P33_LOCATIONS AND dev =: P33_DEVICES  

Now I want that if the user selects all values (LOVs one white point) (or all), then the query must return all values for that LOV.
For example, if for the named LOV P33_DEPARTMENTS 'white' value is selected, then the query must return to the table lines this cointain values "production ' OR 'developing' OR 'project', ecc for the columns named"dep". 
This means that must be the operator AND between LOVs but the operator or inside the LOV even, if the item is selected.

How is it possible? Thank you
			 
SELECT *
FROM T
WHERE dep = nvl( :P33_DEPARTMENTS, dep)
  and loc = nvl( :P33_LOCATIONS, loc)
  and dev = nvl( :P33_DEVICES, loc)

You just need to ensure that, when no value is selected, the LOV will return a NULL value.

How to refresh the list of selection LOV
 
			 
Hello
I use a search of VO show three fields as a, b, c.
My query VO is selet 'a,' b, "double c.
For these 3 attributes, I created three different LovVO with queries to display in the database.
Select a from table1 - values of retrun as a1, a2, a3
Select b from table1. - return as b1, b2, b3 values
c select table1. -returns the values such as c1, c2, c3
Based on the input parameters I am looking for data and I am also erase data from database using callable statement.
For Eg: I select a1 lov of an attribute and search and click on delete button. record a1 will be deleted from the DB but it shows in the dropdown attribute one.
When deleting, I want to update my list of selection.
How can I do this? Please notify.
Thank you

The method you gave, I tried to implement even in SearchVORowImpl.java and AMImpl.java
This method should be in the SearchVORowImpl.java only and NOT in the AMImpl.
Here is the screen shot of JDev 11.1.1.6, so you can see there is method get: ListBindingDefs()

The lovs list - it is just java.uitl.List, so import that class in theSearchVORowImpl.java, or simply declare
java.util.List lovs is getViewDef () .getListBindingDefs ();.


Then go to the section Java in SearchVO and this method in the customer line to export Interface:

Now you can add this method in the method of the pageDef and executables, as methodAction:

Then simply call him when you need it ;-)
		   
 
            
           
 
		     
ORA-01445: cannot select ROWID, or sample, a view of join without key - preserved table form w/report and LOV
 
			 
I create a page "Form on a Table with Report" (APEX 5). Table I has 3 columns: cat_key, item_value, item_description. The cat_key is a foreign key in a table with columns cat_key, cat_value. I created the report and everything works fine.  The page of the report shows my domain cat_key in number, so I want it instead to display the cat_value. I change the field cat_key to a text based on LOV, select my LOV and now when I view the page of report I get the "'ORA-01445: cannot select ROWID from where sample, a join without key preserved table view ' error." The report uses the ROWID as a link to the edit page field.
If I use the same tables and even shared LOV in a report page interactive, it works fine.
What I am doing wrong?
			 
This is a limitation of the IR Apex will rewrite your query to a query that includes the lookup table and the columns. So now you have actually created a query on an inline view, which causes the error. You can see the query apex created when running in debug mode. APEX will join the table of choice with your primary table. For example from one of my IR:
Select 'ID '...
"MSL". "" HIS_COUNTRIES "=> my primary table
) ) b,
(select rv_meaning d, rv_low_value r
of msl_ref_codes_table
where rv_domain = "JOHN".
) L1 = > query My LOV Lookup

...
So, if possible, base your reports and forms on the real primary key, no rowid.
You can also write the IR query with the search yourself:
Select T1.rowid...
of primary_table T1
look_table L1
...
