Nested arrays

I have a table of "panels" and a table of "loops". Each panel
(category) can have many loops (subcategories). The tables are
related by panelid. Each loop has a corresponding panelid. How do I
create a nested array (an array of loops
within each panel object of my array of panels)?
I need help creating this nested array in my CFC.
On the front end, I'm using remote object in Flex to populate
an ArrayCollection. This arraycollection will feed nested repeaters
(a outer repeater that builds an accordion canvas for each panel
and an inner repeater of buttons for the loops within that panel).
If you can help me on the CFC side, that would be great. If
you also know how to reference that array in Flex to build nested
repeaters...bonus.
Thanks,
Don

Access nested array element using this.name - is it possible?

Hi
I've got a nested array containing a series of 2 element arrays containing an object name, and text related to that object.
I've set it up like this:
public var names:Array = [["instance name 1", "text for first object"],["instance name 2", "text for second object"], ...]];
What I'm trying to do is to have the text related to the object appear in a text box when the object is moved.
This is all set up within a class containing code for the drag and drop functions.
If I set the text box to show a specific element, such as:
MovieClip(parent).text_box.text= names[2][1];
it works fine. But I can't get it to create the value for the first bracket from the this.name attribute.
I had it working for 2 arrays - one with the name and another with the text where the code was;
MovieClip(parent).text_box.text= texts[names.indexOf(this.name)]; (arrays named 'names' and 'texts', text box named 'text_box')
I'm hoping there's something similar that I can do for the nested array, but everything I try gives me the #1010 error - term undefined.
Is there an easy way to sort this out - or am I better sticking with the 2 array version?
(BTW this is my first go at using arrays)
Thanks

Why not use an Object for this, like:
var oTexts:Object = {
                              "clipname1":"text for clip 1",
                              "clipname2":"text for clip 2",
                              "clipname3":"text for clip 3",
and then jsut use sometihing like this
var txt:String = MovieClip(parent).oTexts[this.name];
etc. ..

How to find and modify item in a nested array collection?

Hi,
would anybody know how to find and modify item in a nested
array collection:
private var ac:ArrayCollection = new ArrayCollection([
{id:1,name:"A",children:[{id:4,name:"AA",children:[{id:8,name:"AAA"}]},{id:5,name:"AB"}]} ,
{id:2,name:"B",children:[{id:6,name:"BA"},{id:7,name:"BB"}]},
{id:3,name:"C"}
Let's say I've got object {id:8, name:"X"} , how could I find
item in a collection with the correspoding id property, get handle
on it and update the name property of that object?
I'm trying to use this as a dataprovider for a tree populated
via CF and remoting....
Thanks a lot for help!

Thanks a lot for your help!
In the meantime I've come up with a recursive version of the
code.
This works and replaces the item on any level deep:
private function findInAC(ac:ArrayCollection):void{
var iMatchValue:uint=8;
for(var i:uint=0; i<ac.length; i++){
if(ac
.id == iMatchValue){
ac.name = "NEW NAME";
break;
if(ac
.children !=undefined){
findInAC( new ArrayCollection(ac.children));
However, if I use the array collection as a dataprovider for
a tree and change it, the tree doesn't update, unless I collapse
and reopen it.
Any ideas how to fix it ?

Complex query - improve performance with nested arrays, bulk insert....?

Hello, I have an extremely complicated query, that has a structure similar to:
Overall Query
---SubQueryA
-------SubQueryB
---SubQueryB
---SubQueryC
-------SubQueryA
The subqueries themselves are slow, and having to run them multiple times is much too slow! Ideally, I would be able to run each subquery once, and then use the results. I cannot use standard oracle tables, and i would need to keep the result of the subqueries in memory.
I was thinking I write a pl/sql script that did the subqueries at the beginning and stored the results in memory. Then in the overall query, I could loop through my results in memory, and join the results of the various subqueries to one another.
some questions:
-what is the best data structure to use? I've been looking around and there are nested arrays, and there's the bulk insert functionality, but I'm not sure what is the best to you
-the advantage of the method I'm suggesting is that I only have to do each subquery once. But, when I start joining the results of the subquery to one another, will I take a performance hit? will Oracle not be able to optimize the joins?
thanks in advance!
Coop

I cannot use standard oracle tablesWhat does this mean? If you have subqueries, i assume you have tables to drive them? You're in an Oracle forum, so i assume the tables are Oracle tables.
If so, you can look into the WITH clause, it can 'cache' the query results for you and reuse them multiple times, also helpful in making large queries with many subqueries more readable.

Nest array in a custom component

Hello and thanks in advance,
I am building a custom datagrid component name custDG. It is a canvas containing the DG and some other visuals. So the actual component is based on canvas and has a DataGrid nested.
I have also build a custom class name config based on Array to hold the DG column information
AND a custom object class name col to hold each column information inside the config array class...
My question is how to make it possible for user to nest the array and columns inside the custom component when adds it to an application. For example:
<mike:custDG... >
     <mike:config>
          <mike:col.../>
          <mike:col.../>
          <mike:col.../>
     </mike:config>
</mike:custDG... >
Want to make something similar to the columns-datagridcolumn thingie but with custom classes in a custom component.
Anyone plz?
Thanks

I finally found how to set a default skin to a custom component so that users of my component will not have to set again the skinClass value of my component.
You have to create a defaults.css file at the root of your library and tell the compiler to take it into account.
The remaining problem is about the compiler. There are some steps before success and they are a bit mysterious/unclear....
I found 2 or 3 blog articles explaining those steps but the compiler arguments to use are all differents in each article...
Here are the links I found:
http://www.unitedmindset.com/jonbcampos/2010/05/12/creating-custom-spark-components/

http://flexdevtips.blogspot.com/2009/06/default-stylesheet-in-swc-flex-library.html
Following the first article guidelines has been successful for me but I'm not marking this topic as Resolved because I'd like some answers about this whole thing...

SUP Nested Array Problem in REST Response while Creating MBO

I am using SUP 2.0 to build MBOs from a rest web service which sends me a list of profiles in which each profile has a list of industries associated with him that mean my resultset contains an array of industries in the XML response for each of the profile.
What SUP is doing when I am trying to build MBOs and execute them, it is returning me duplicate rows as the MBO is not able to hold complex object like array or list. Each profile is repeated n times if the profile has got n industries,
How to handle this kind of response in SUP ?
My Profile structure looks like
Profile {
STRING city;
STRING name;
STRING profileID;
STRING[] industries;

Okay I am defining it more elaborately.
suppose from a web service u get a response which contains a list of profiles as its result. Now each profile has got a list of industries as well. But MBO in SUP don't support complex data type like array of objects. Now when i try to preview, if i had 2 profiles in the resultset and say 1st profile 'a' has got 3 industries and 2nd profile 'b' has got 2 industries so now my resultset contains 5 rows like
Name           City            ProfileID           Industries
a                   c1              p01                   i1
a                   c1              p01                   i2
a                   c1              p01                   i3
b                   c2              p03                   i4
b                   c2              p03                   i7
How to handle it in a better way, Can I use SUPObjectList somehow to hold list of Industries for each profile in the resultset without getting repeated entries.
Thanks

KVO with nested arrays?

I'm working on an app with the typical UITableView displaying rows grouped into sections. I have an NSMutableArray of Section objects, each of which has an array of Entry objects. Manual KVO is working for adding and removing Section objects. I can use a key path of "sections" and everything works as expected.
I'd like to use KVO for operations on the entries array in each Section object so I can add/remove table rows as entries are added/removed in each Section. Using a key path of "sections.entries" doesn't work. I get an NSInvalidArgumentException with [<NSCFArray 0x104fbb0> addObserver:forKeyPath:options:context:] is not supported. Key path: entries in the console. After a bit of thought, the error makes sense: the sections property is an NSMutableArray, which of course doesn't have an entries property.
How do I do this? Is there a better way that I'm missing?

Well, after a bit of fiddling I found a solution. I'm not sure if it's the right solution, but it appears to work.
I had been assuming that the key path had to be somehow related to actual properties of objects. But, on a whim, I made up a key path that corresponded to nothing, and it worked. I can issue and observe events on my fake key path just fine.

Issue with Mulidimensional Nested Table

Hi All,
I am studing Multidimensional Nested table and have the below code:
DECLARE
TYPE table_type1 IS TABLE OF INTEGER;
TYPE table_type2 IS TABLE OF TABLE_TYPE1;
table_tab1 table_type1 := table_type1();
table_tab2 table_type2 := table_type2(table_tab1);
BEGIN
FOR i IN 1 .. 2
LOOP
    table_tab2.extend;
    table_tab2(i) := table_type1();
    FOR j IN 1 .. 3
    LOOP
      IF i = 1
      THEN
        table_tab1.extend;
        table_tab1(j) := j;
      ELSE
        table_tab1.extend;
        table_tab1(j) := 4 - j;
      END IF;
        table_tab2.extend;
      table_tab2(i)(j) := table_tab1(j);
      DBMS_OUTPUT.PUT_LINE('table_tab2(' || i || ')(' || j || '): ' ||
                           table_tab2(i) (j));
    END LOOP;
END LOOP;
exception
when others then
    dbms_output.put_line(sqlerrm);
END;
This code is working fine as of now.But,If i comment below code(table_tab2 is also extended latter):
table_tab2.extend;
    table_tab2(i) := table_type1();
then it gives me error 'Subscription Beyond count'.
I would like to know why i need to extend table_tab2 twice?
Thanks!

This code is working fine as of now
No, it isn't. Make sure you have serveroutput on. If you do, you get this as script output (I am using SQL Developer):
anonymous block completed
...meaning no exception was raised to client, because you trapped it, but the DBMS Output window gives:
ORA-06533: Subscript beyond count
...with no indication of which line, because you suppressed it (why?). If you drop the worse than useless exception handler, you get:
ORA-06533: Subscript beyond count
ORA-06512: at line 22
06533. 00000 - "Subscript beyond count"
*Cause:    An in-limit subscript was greater than the count of a varray
           or too large for a nested table.
*Action:   Check the program logic and explicitly extend if necessary.
A bit more helpful, yes? and with less code. Here is a revised block that writes the loop variable product to the nested array, with its output, initialising and extending correctly:
DECLARE
TYPE table_type1 IS   TABLE OF INTEGER;
TYPE table_type2 IS   TABLE OF table_type1;
table_tab1            table_type1;
table_tab2            table_type2 := table_type2();
BEGIN
FOR i IN 1..2 LOOP
    table_tab1 := table_type1();
    FOR j IN 1..3 LOOP
      table_tab1.extend;
      table_tab1(j) := i * j;
    END LOOP;
    table_tab2.extend;
    table_tab2(i) := table_tab1;
END LOOP;
FOR i IN 1..table_tab2.COUNT LOOP
    FOR j IN 1..table_tab2(i).COUNT LOOP
      DBMS_OUTPUT.PUT_LINE('Row ' || i || ' element ' || j || ' = ' || table_tab2(i)(j));
    END LOOP;
END LOOP;
END;
Row 1 element 1 = 1
Row 1 element 2 = 2
Row 1 element 3 = 3
Row 2 element 1 = 2
Row 2 element 2 = 4
Row 2 element 3 = 6
You could alternatively dispense with table_tab1 if you prefer, and write directly each element.

For your questions:
1) I don't want to store in the database as a nested table
2) I don't want to retrieve data from the database. Data will come from function split_date() parameter and data will be processed in the function and function will return it in nested table format. For more detail please look at the raw function SQL.
I have a SQL like:
WITH all_dates
        AS (SELECT tr_start_date AS a_date, 0 AS black_out_val FROM travel
            UNION ALL
            SELECT tr_end_date, 0 FROM travel

            SELECT bo_start_date - 1, 1 FROM black_out_dates
            UNION ALL

SELECT start_date, end_date
    FROM got_analytics
   WHERE black_out_cnt = 0 AND start_date < end_date
ORDER BY start_date;I want to change the tables black_out_dates and travel to Nested Array so I can use it in a function with Nested Array travel and Nested Array black_out_dates parameters and the function will return Nested Array of date ranges.

Nested Groups in Component Model

Is it possible to have a nested group in the Component Model? For example, I have a group of metatdata. That group is called Class and consists of the following fields:
- Department
- Number
- Title
- Level
There can be 1:n of these Classes.
These Classes compose a group called Notice. There can be 1:n Notices. The metadata may look like this.
Notices
-- Notice1
---- Dept1
---- Number1
---- Title1
---- Level1
-- Notice2
---- Dept2
---- Number2
---- Title2
---- Level2
I'm busy wearing a different hat at the moment on another project and don't have a lot of time to research this. Thoughts? Thanks in advance for any contribution.

Hi Bill,
Here are a few ideas that i hope help. In answer to your question, Groups cannot have groups.
1. Your group could add a new attribute in your group that is an array of another BPM Object in a "Model" object
2. You could store the information nested in a relational database.
When it comes to a presentation, you'd probably want a header that shows the list of "Class" (surprised it let you name the group this without a runtime error). The user would then click one of the "class" items at the top of the scren and then you'd display the nexted group in a section of the screen below the header of the presentation. You'd use a "View" object for the UI and this View would have a group called "NestedStuff" dedicated to displaying the nested array for the class group item picked in the header.

How to see the output of associative array in procedure

Hi ,
Though the table has the records , the associatve array declared on this table is showing 0 records..
Create or replace package test_pak1 as
FUNCTION map_object ( obj_typ_in VARCHAR2 ) RETURN VARCHAR2;
CURSOR c_c1
    IS
SELECT *
        FROM dept;
    TYPE test_ttyp IS TABLE OF c_c1%ROWTYPE INDEX BY PLS_INTEGER;
procedure search_obj(obj_type varchar2);
end;
Create or replace package body test_pak1 as
FUNCTION map_object ( obj_typ_in VARCHAR2 ) RETURN VARCHAR2
     IS
begin
       dbms_output.put_line ('Hello');
return 'abc';
end;
procedure search_obj(obj_type varchar2) is
   test_tab test_ttyp;
begin
    DBMS_OUTPUT.put_line ('nested array count value'|| test_tab.COUNT);
                         FOR i IN 1 .. test_tab.COUNT LOOP
                             dbms_output.put_line( test_tab(i).deptno||' '|| test_tab(i).dname); end loop;
   end;
end;
begin
test_pak1.search_obj('HYD');
end; Though the table has the records the count of the associative array is showing 0 records ... Why
Thanks

ADF - Collections with Arrays Not Displaying

I am using JDeveloper 10.12.
Within the applicaiton I am developing I have the following:
nominalRecord - Java Bean
nominalRecordCollection - Collection of nominalRecords
I have generated a data control from the nominalRecordCollection. The data within each of the nominalRecords is being populated correctly - I know this as I have written a sperate test class to display the data to screen.
I have tried to display this collection using ADF by dragging and dropping the nominalRecordCollection data control onto a data page. Unfortunately this does not seem to be displaying the data correctly.
Some of the data within the nominalRecord is contained within Arrays as there are multiple values. For Example:
String surname;
String firstname;
String[] descriptionCode;
String[] descriptionText;
This is necessary because an individual may have more that one descriptive features - I need to store them like this because an individual can have any number of descriptive features. e.g.
01 - Tattoo
02 - Beard
03 - Wig
etc etc.
When the applicaiton is executed the data that is stored within the String variables within the nominalRecord classes are displayed correctly BUT the data stored within the arrays is not displayed at all.
I've speant the afternoon looking into this but have not managed to find a suitbale solution. Can ADF in fact render Collections that have Arrays in them?
I'd appreciate any help/assistance with this matter.
Thanks in advance for your help
David.

What do the JSTL expressions look like where you're trying to access the nested array values?
See example #45 on my Not Yet Documented examples page of my blog for an example based on your setup here.

Nested Objects for a Data Provider in a Data Grid, not displaying data

Hi, I have a datagrid and the dataprovider for this grid is the result of a RPC call. The result set has the following structure:
Array
[0]->Object #1
      [one] => 1
      [two] => 1
      [three] => Object #2
          [apple1] = > Object #3
              [color] =>    red
              [rate] => 20
          [apple2] => Object #4 ( the    number of apples is dynamic, apple3,apple4 .. and so on)
              [color] =>    blue
              [rate] => 100
and so on ... so the number of apple objects will vary since its
dynamic. How do I display this data in a datagrid ??? Please help!! I
saw many articles on creating the "Nested DataGridColumn " classes...
like this :
http://active.tutsplus.com/tutorials/flex/working-with-the-flex-datagrid-and-nested-data-structures/
it helps, but the problem with my data is that some of the indexes (like apple1,apple2 etc) are dynamic.
Also, my flex application is a desktop application (in case that matters). Just to see whats going on, I
dropped all the nested arrays and used a plain simple one-dimensional array. Even in this case the data
isnt getting displayed.
I dont know what im doin wrong. the datafields, labels etc e'thing is correct. I even debugged and
im getting the result on the flex side. whats going on ?

No luck ... i converted the result set to a List, and even tried with an iList. Same problem - nothing gets displayed...
I have no idea whats happening ....
This is my code :
[Bindable]private var privilegesArray:ArrayCollection = new ArrayCollection();
public function init():void{ // called on creation complete
                RO.getPrivileges.addEventListener(ResultEvent.RESULT,handleGetPrivileges);
                RO.getPrivileges();
protected function handleGetPrivileges(event:ResultEvent):void{
                privilegesArray = event.result as ArrayCollection;
<mx:DataGrid id="privilegesDG" dataProvider="{privilegesArray}" width="100%">
        <mx:columns>
            <mx:DataGridColumn headerText="Name" dataField="name" />
            <mx:DataGridColumn headerText="Alias" dataField="alias" />
        </mx:columns>
    </mx:DataGrid>
The data that gets returned is smthing like this : (for the moment I have removed all the nested objects and arrays and returning just a simple plain array)
Array => [0] => Object #1
                          [name] => some name
                          [alias] => alias

Nested ArrayCollection

I have an ArrayCollection of 3 arrays: level0, level1, and
level2. The level0 array item a set of x,y coordinates. The level1
x,y coordinates are used to position ten objects relative to the
position of the level0 object. Similarly, the level2 x,y
coordinates are used to position ten objects relative to the
position of a level1 object.
I wish to designate the position of an object, say an HBox,
with code something like:
<mx:HBox
x="{Number(nodeCoordinates.level0[0].x)+Number(nodeCoordinates.level1[3].x)+Number(nodeCo ordinates.level2[9].x)}"
/>
When I compile the code I get the followign error message:
"1119: Access of possibly undefined property level0 through a
reference with static type mx.collections:ArrayCollection."
I know this isn't a clean way to address the problem. At this
early point I'm just trying to heavy-handedly get the app to do
want I want. I'll make the code more efficient later.
How can I reference and use the values in a nested
ArrayCollection?
Thank you in advance!

You could try something like
x="((nodeCoordinates.getItemAt(0) as
ArrayCollection).getItemAt(0) as
YourDataType).x..."
But I think what rtAlton is trying to say is that there's an
implication
here that you've got a "thing" at level 0 that has an x
coordinate, and then
you have another "thing" placed at level1 relative to the
first thing, and
then there's this HBox that's being positioned relative to
the level1
object.
So it seems like you could do something that puts the level 0
and level 1
values into a variable and adds them together, then the level
2
ArrayCollection is pulled out as a separate variable,
simplifying the
references. Possibly this could be done with custom
components that
encapsulate each level.

Collapsing menu from array

I need to create a dynamic collapsing menu from an array. so
far I have the array and first level of the menu working. Now I
need to create the functionality of the subMenu and I am stumped.
Is there any good references out there that might be able to walk
me through this process? Here is my code and my source file can be
found here
http://www.actionscript.org/forums/showthread.php3?t=122921

Sorry I noticed errors in code and in the fla. If you have
looked at this please check out the new one. The nested array is
partially loading but then I loose the links that are above it.
Here is the updated fla which can be found at the link above and
