How to get Value of a item of first record when current record is second

How to get Value of a item of first record when current record is second in Form6i ?
get_item_instance_property dose not allow to get value.

Gerd,
You're right, there are several other triggers that must be coded, but I was responding to Steve's statement about Inserting or deleting records from the multi-record block. For the record, I use the following to manage a Record Group:
* When-New-Block-Instance - Initialize the RG
* block Post-Query - populate the RG
* When-Create-Record - add new record to RG
* When-Remove-Record - remove record from RG
* block When-New-Item-Instance - capture previous value of the item or row
* When-Validate-Item - Item specific Insert, Update, Delete of values in the RG
There are a few other places as well, but these are the minimum. It might seem like a lot of code, but then again, I don't use this solution for every multi-line block. Like all tools, you use the right tool for the job. :-)

How can I delete null values from List Item?

Hi Friends,
I used List item for field job_Type, I entered values in List item at design time through property pallet. When I run form I will see null values in this List Item.
How can I remove these null values from the List?
Best regards,
Shahzad

Dear Shahzad,
It can be removed by adding the following code in the When-new-Form-Instance.
Set_item_property('List name', required, property_true);
:block_name.list_name := <put your default value here>; (If you didn't oput the default value, then you will get some problem and the cursor may not navigate away from the list).

          Set pSet = this.getSelectedComp().getParameterses();
          int size = pSet.size();
          this.instanceValue = new String[size];
          int i = 0;
          for (Iterator it = pSet.iterator(); it.hasNext();) {

               HtmlOutputLabel outputLable = new HtmlOutputLabel();
               HtmlInputText inputText = new HtmlInputText();
               inputText.setId("p" + i);
               String valueBindingExpression = "#{dynamicInputGroupBean.instanceValue["+i+ "]}";

               group.getChildren().add(outputLable);
               group.getChildren().add(inputText);
               i++;
          // group.getChildren().add(new HtmlInputText());
          return group;
     }as codes show above, i successfully genera HtmlInputText dinamicaly�C
but i got problems while i try to print those values...
after the the jsp page presents in my browser,
i input some words in the input components,
and then click a commandButton hold an action to print their value
action code :
String[] tempArray = this.getInstanceValue();
for (int i = 0; i < tempArray.length; i++) {
System.out.println(tempArray);
only NULL has been printed in the consol ....not the word i inputed!!!
so my question is how can i get values from those
dinamically generated HtmlInputText ????

This approach is odd. What's the functional requirement after all? You normally attach the inputtext value to a backing bean property and do the desired command button action which is attached to a backing bean action method. In this method you then use the value for the query.

How to get values from an IFrame...

Hi everyone. I have come to a complete stop i my project and need to ask the following: How do i get the values from an IFrame.
Situation: I have a main.jsp page that contains an IFrame(data.jsp). Data.jsp is basically made up of a bunch of checkboxes. The state of these boxes(checked or unchecked) is determined and set by a JAVA program and the results are then stored in a StringBuffer. Contents of Stringbuffer could look something like this: <tr><input type='checkbox' name='box0' CHECKED></tr>.
The StringBuffer in then presented in the IFrame(data.jsp) like so: <%=res.getInfo()%>
The user should be able to check or uncheck the boxes from the main.jsp page then when pressing a submit button the changes should be stored in a DBase.
After the submit button have been pressed i go into my Servlet's doPost() method for some basic processing. This is were the problem starts. I usally use HttpServletRequest.getParameter(String param) to get values from the main.jsp page. But these checkboxes are stored in the IFrame, so how do i go about to retrieve the values from data.jsp from the doPost() method or in some other way maybe. This is quite urgent and i hope that i have explained the scenario in enough detail.
Any help would be greatlly apritiated.
Best regards
Peter

How to get values from a stored package variable of type record ?

Sir,
In my JClient form, I need to get values from a database stored package variable of type record. And the values are retained in the JClient form for the whole session. The values are copied only once when the form is started.
What is the best way to do that ?
Thanks
Stephen

Stephen,
not sure what your model is, but if it is Business Components, I think I would expose the properties as a client method on the application module. This way all JClient panels and frames will have access to it. You could use a HashMap to store the data in teh app module.
If JDBC supports the record type, then you should be able to call it via a prepared SQL statement. If not, you may consider writing a PLSQL accessor to your stored procedure that returns something that can be handled.

How to get data from list of values (LOV) to be displayed in a text field ?

Hi guys,
I am very new to Oracle APEX so please spare me if it is a silly question. How can I get the selected values from a set of list of values (LOV) displayed in a text field (or text area or so) ? Fox example, in my form I create 4 items: STATE, COUNTY, STREET, ZIPCODE and all of them are LOV (list of values). I also create 2 buttons (ADD & REMOVE). Then I create a test field (or text area name SELECTED RECORD). Now here is what I want to do with my form:
When I set the values for all 4 fields, I will click on the ADD button then I want those values be displayed in the text field.
For example, if the selected values are:
STATE = Alabama
COUNTY = Abbeville
STREET= 1 Street
ZIPCODE = 36310
And the ADD button is pressed. Then in the text field I want it displays like this:
Alabama,Abbeville,1 Street,36310
If I choose other values and click ADD again, a new line will be added into the text fields (text area). If I click the REMOVE button, then it will clear those two line in the text field.
Would it be possible to do it? Any help will be greatly appreciated. Thanks in advance.

If you can live with the page being submitted and refreshed, make your ADD button do a submit with a request value of ADD and make your REMOVE button do a submit with a request value of REMOVE.
Then create two computations (one firing with a condition of Request = ADD and the other firing with a condition of Request = REMOVE).
In the ADD one, concatenate the values together into the text area (most likely a PL/SQL computation wiill be what you want). In the REMOVE one, set it to null with a PL/SQL computation.
If you want it done without submitting the page, make the buttons each do a redirect to a URL but instead you will have to write two short javascript functions in the page HTML header to manipulate the field values. Each button would call each javascript function in an onclick event.

How to Get the required List Item values by using Where Clause

I have two tables named "TAX_RULES","BILL"
1. " Tax_Rules" (Sub_Head_Code,Tax_ID,Tax_Percentage)
{ While "Sub_Head_Code" field is unique,
Tax_ID describes that there are two kinds of Tax_IDs based on Tax_percentage which is 6% for some Sub_Head_Codes and 3.5% for the remainng Sub_Head_Codes. I have given Tax_ID 1 for 6% and Tax_ID 2 for Sub_Head_codes having 3.5%. }
2. "BILL" (Bill_ID,Sub_Head_Code,Tax_ID,Bill_Amount)
{While "Bill_ID" describes unique Bill Identification Number,
Sub_Head_Code and Tax_ID are behaving like composite foreign key from Tax_Rules table}
I have design form for both tables.
In BILL form i am trying to get values of Tax_ID from Tax_Rules table at run-time by using WHEN-NEW-FORM-INSTANCE.
For this whenever i select a Sub_Head_Code in Bill Form, all the Tax_IDs that i have recorded against each Sub_Head_Code which is either 1 or 2 against 6% and 3.5% respectively.
But I want that whenever i select a "Sub_Head_Code", Only that Tax_ID which is associated with that Sub_Head_Code ahould come in the LIST ITEM.
I have used WHERE clause but that is useless.
Following is the Code that i have applied in the WHE-NEW-ITEM-INSTANCE Trigger at FORM LEVEL
<CODE>
DECLARE
     rg_n1 VARCHAR2(40) :='TAX_ID';
     rg_idn1 RecordGroup;
     gc_idn1 GroupColumn;
     errcode NUMBER;
BEGIN
     CLEAR_LIST('BILL.TAX_ID');
     rg_idn1 := Find_Group(rg_n1);
IF      Id_Null(rg_idn1) then
          rg_idn1 := Create_Group(rg_n1);
     gc_idn1 := Add_Group_Column(rg_idn1,'EXPLAIN',CHAR_COLUMN,60);
          gc_idn1 := Add_Group_Column(rg_idn1,'TAX_ID',CHAR_COLUMN,3);
     END IF;
     errcode := Populate_Group_With_Query(rg_idn1,'select TAX_ID,TAX_ID from TAX_RULES');
     POPULATE_LIST('BILL.TAX_ID',RG_IDn1);
END;
</CODE>

In the Tax Rules table, you state:
"Sub_Head_Code" field is unique
In the Bill table, you state:
Sub_Head_Code and Tax_ID are behaving like composite foreign key from Tax_Rules table
If the Sub_Head_Code is unique, then it's acting as a primary key, so Sub_Head_Code and Tax_ID in the Bill table are not behaving like a composite foreign key. The Sub_Head_Code is a foreign key, and the Tax_ID is irrelevant as far as keys are concerned.
It is not clear what it is you want to do.
If you want to display the Tax_IDs from the Bill table when you select a Sub_Head_Code from the Tax_Rules table, then change your query to:
select TAX_ID, TAX_ID from BILL where Sub_Head_Code = :Tax_Rules.Sub_Head_Code
If you want to display the Tax_IDs from the Tax_Rules table when you select a Sub_Head_Code from the Bill table, then change your query to:
select TAX_ID, TAX_ID from TAX_RULES where Sub_Head_Code = :Bill.Sub_Head_Code
If this is not what you want, then clarify what it is you want to do. Don't say:
"I want that whenever i select a "Sub_Head_Code", Only that Tax_ID which is associated with that Sub_Head_Code"
because it is not clear what tables you are referring to.

Problem passing value from List Item to List Item

OK I will try to explain what I am trying to do. I have a Form that List Item at the top and they cascade from left to right. When I get to the BPOST_TAG I choose the Bpost then move to EPOST_TAG to choose the Epost. The EPOST_TAG should show all the Epost that go with Bpost you already chose, but it only showing 1 or 2. Below is the example of how should work!
SYSTEM     COUNTY     ROUTE   BPOST_TAG      EBPOST_TAG
1 77 80 025 030
------- The Return Values Should be as below-------------------------------------------------
Sy Co Route Dir Bpost Epost Miles Descrption
1 77 80 1 025 026 ? ?
1 77 80 1 026 027 ? ?

1 77 80 2 028 029 ? ?
1 77 80 2 029 030 ? ?
The top 5 List Items are based on the first Data Block (PMISCURR) and the bottom 8 columns are based on the second Data Block (PMISCURR1).
I have PRE-QUERY on the first Data Block (PMISCURR), below is code for the PRE-QUERY.
DECLARE
Wh_clause VARCHAR2(200);
BEGIN
IF :PMISCURR.SYSTEM is not null then
     Wh_clause := 'SYSTEM = '||:PMISCURR.SYSTEM;
END IF;
IF :PMISCURR.COUNTY is not null then
     Wh_clause := WH_CLAUSE ||'AND COUNTY = '||:PMISCURR.COUNTY;
END IF;
IF :PMISCURR.ROUTE is not null then
     Wh_clause := WH_CLAUSE ||'AND ROUTE = '||:PMISCURR.ROUTE;
END IF;
IF :PMISCURR.BPOST_TAG is not null then
     Wh_clause := WH_CLAUSE ||'AND BPOST_TAG = '||:PMISCURR.BPOST_TAG;
END IF;
IF :PMISCURR.EPOST_TAG is not null then
     Wh_clause := WH_CLAUSE ||'AND EPOST_TAG = '||:PMISCURR.EPOST_TAG;
END IF;
END;
OK It's just not my day I can't even get this line-up! :)

How to get values from afLiterator ?

Hi All,
I have a grid populated records using af:Iterator. Row are populated from the List model(say product list). The iterator component i binded in the bean.
Now i have showing 5 records per page. total 3 pages are there.
There is a boolean check box for each rows. and a common check box to select all the rows in the page.
I dont know how to get the rows of current set when i select the SelectAll checkbox, similarlly i have to do the same when i go to page 2 of the iterator.(page 2 means next range of records in the iterator)
My requirement is using the af:iterator not af:table.. please help

Hi,
af:iterator does i) not keep track of selection states and ii) stamp data
i) The selection state needs to be tracked with <f:attribute ...> tags added to the check box component. The value of the attribute should identify the row (ideally by a unique key). The name of the attribute is up to you. When you iterate over the selected check boxes you call getAttribute() on the check box component to access your custom attribute for identifying the row instance
ii) rows are no individual instances and there fore cannot be directly accessed. af:forEach may be a better fit for your use case as it created component instances that then allow you to call the JSF parent container and getChildren on this. You then look for the checkbox component instances and verify its selection state. For selected components you the access the custom attribute

Getting values from dynamic items

I've created some items on my page using APEX_ITEM. This is a really cool feature, it allows extreme flexibility. My problem is, I can not get the value out of the textbox I've created.
It doesn't appear in session state at all. I thought this wasn't going to happen though.
I've tried a computation to get the value into a hidden item. These items appear null upon submittal.
I came across APEX_APPLICATION.G_F01 - but this isn't working for me either... It appears to be used to access an array and I must not be using it correctly.
Anyone got any pointers on how to get the information out??

Here is the formatted code (put pre and */pre* before and after blocks, replacing asterisks with matched square brackets):
v_item_desc varchar2(4000);
v_counter number;
cursor v_item_cursor is
    {select statement}
begin
v_counter := 1;
htp.p('< table>');
for aRow in v_item_cursor
loop
    select X
      into v_item_desc
      from Y
      where Z = v_counter;
    htp.p(
      '< tr>< td>< span style="line-height:25px;font-size:15px">'|| apex_item.display_and_save(v_counter, null, null, null)||v_item_desc||'< /span>< /td>');
    htp.p(
      '< td>'||apex_item.text(v_counter, null, 30, 4000, null, 'P6_SUM_SELECT_'||v_counter)|| '< /td>< /tr>');
    v_counter := v_counter + 1;
end loop;
htp.p('< /table>');
end;In your after-submit process, loop over apex_application.g_f01 from 1..apex_application.g_f01.count for the array created when you used v_counter=1, etc.
