Add element in array

Hi,
I have one String array.
I need to create another String array with the content of 1st array and additional 1st element in the 2nd array with "Product" text.
2nd array[0] = Product;
How do i do it
Thanks

String[] array1 = {"1", "2", "3"};
String[] array2 = {"4", "5"};
String[] array3 = new String[array1.length+array2.length];
System.arraycopy(array1, 0, array3, 0, array1.length);
System.arraycopy(array2, 0, array3, array1.length, array2.length);
here, the array3 will have all the elements in order ie, 1,2,3,4,5.
In case you need to use array2, assign array3 to array2 ie, array2 = array3
Hope that helps.
Regards,
Sumant

Add element to array of cluster

I have an array of cluster. Cluster contains two elements. How to add an element in cluster at run time on the second position efficiently? In other words dont want another copy of cluster which contains three elements and copy the original two elements plus the new element.
Original array of cluster lets say has two element Temp1 and Pressure 1.
Need to add another element in cluster and now the array of cluster will be Temp1, Volt1 and Pressure 1. So Volt 1 is added to all cluster elements at second order throughout the array of clusters programatically.

It is unclear from your original post what the problem you need to solve actually is. Are you trying to create a user interface? Do you need to dynamically add arbitrary data to a data set, or is it a fixed set of functionality that can be dynamically changed in predetermined ways?
Having done it, I will recommend you not try the scripting and subpanels approach. There are almost always better ways.
Remember that your data structures do not need to mirror your user interface. If you were trying to display the temperature, voltage, and pressure data to the user, a multicolumn listbox may be more appropriate than a raw cluster in an array. Internally, this would allow you to maintain the temperature, voltage, and pressure as separate arrays and only display the ones you want in the listbox.
Please give us a more information on the problem so we can help you with an easier solution.

Is there a way you can add elements dynamically to an existing array??

hey guys... i need to add elements to an array dynamically... how do i do that?
for example... in one of my functions i do..
     for each(var item:Object in fileList){
          fileListArr.push(item);
and in a later function i need to add one more element to my fileListArr...
so i tried doing
fileListArr[indexNum].push({
     key:videoKey
so i need to have an array which resembles something like this...
Before adding elements...
fileListArr:
     [0]: name:test1
            Size:12K
            caption:testing caption
            number:1
     [1]: name:test2
            Size:12K
            caption:testing caption
            number:2
after adding key to array
fileListArr:
     [0]: name:test1
            Size:12K
            caption:testing caption
            number:1
            key:xyxyyy11y1yy1y1y2y2u33n
     [1]: name:test2
            Size:12K
            caption:testing caption
            number:2
            key:iiduudjmenri112jj2n4n3m2j1j21
any ideas?

hmm interesting... so i made the changes... i changed the array to arraylist and the code i have is as follows... but i still get an error... the error says ... "ReferenceError: Error #1056: Cannot create property key on flash.net.FileReference."

How to add elements into Object[][] type of list, in runtime?

I have Object list, ie.
    final Object[][] data = {
        {"January",   new Integer(150) },
        {"February", new Integer(500) },
        {"March",     new Integer(54) },
        {"April",     new Integer(-50) }
    };How can I dynamicly add new elements in it, at the runtime?
Thank you in advance!

Do I have to remove 'final' for that, and then add
elements?
No. you can't change an array's size.
You can do this
Object[][] arr = new Object[numRows][numCols];But once you've created it, its size can't change.*
I don't know what you're doing, though, and what actual data you're putting in, but Object[][] holding rows of [String, Integer] is almost certainly a poor data structure. Think about creating a class the represents one "row" here and then create a 1D array of that class.
* Okay, you can kinda sorta effectively "change" the size of second and subsequent dimensions, since a multidimensional array is an array of arrays. I wouldn't recommend it though: int[][] arr = new int[3][2]; // a 3 x 2 rectangular array of int--it's an array of array of int, with 3 "rows", each of which is an array of int with 2 elements.
arr[0] = new int[10]; // now it's a jagged array whose first row has 10 elments instead of 2Here we haven't changed an array's size, just replaced one of its elements, which is also an array, with a new, larger array.

Merging elements of array

Hi,
I am new to programming.
I have a sensor that sends a data stream through a serial port. I have collect all that data in a 1D unsigned byte array. Now, lets say my 1-D array is [12][45][65][12]...... where each "[ ]" is a element of the array. Now to make sense of this data what i need to do is merge two elements the array and multipy it by 2/(2^15). i.e. My converted data should by [1245]*2/(2^15). Basically 2 bytes together makes sense. I can do a simple add of each element. Also the other problem is,data from the sensor is a stored as the 1-D array of unsigned byte. However, the converted data is supposed to be signed 16-bit integer.
Please give any suggestions on how to go about doing this.
Siddhant Shah

Another option is "decimate&Join". (Here it is easy to change the byte order if needed).

Add element in dropdown list dynamically

Hi All,
I am facing a problem in adding item in a dropdown list dynamically.
When i get dropdown list through IgetElementById get null.
var list = document.getElementById("targetgroupname");
here list comes as null. Now I've to fill this list. I am using below code -
for(var j=0;j< com.length;j++){
iist.options[j]= new Option(com[j],com[j]);
But it is not working. My list is not getting filled with these values.
I doubt due to var list -> null it does not allow to add element.
But I am not getting any clue, how to initialize it.
Please suggest, I am new to javascript.
Thanks & Regards,
Sneha.

Hi,
Thanks for the reply, yes the select box has that id - targetgroupname.
actually there are 2 dropdown lists, Based on the selection of first dropdown list another list shd be filled.
So I've written a script at "onchange" of first dropdown list. It works fine when a value gets changed at first dropdown list.
In some cases I've to display a preselected value at first list ( which comes from previous page as parameter), in that cases there will be no onchange on first list, so I've called the script function manually after creating the first list,like below :
<SCRIPT> checkSource();</SCRIPT>
and in this case it does not work & I get a null when i try to read the 2nd list.
But I am not sure why it is happening.. may be it is not loaded /created on page when i am calling it.
If yes, what shd I do ?
Thanks for your time.

Sneha

In .java add elements to .jsp

Hello!
I'm just beginning and can't understand one thing:
When I create JSPDynPage, system create JSP and JAVA file - it's clear. Then I add elements to form in JSP, for example, Layout.
Can I add, for example, row into that Layout in .java file?
    .JSP:
<hbj:form>
         <hbj:formLayout
             id="myLayout"
             width="100%">
             <hbj:formLayoutRow
                     id="Row1">
                     <hbj:formLayoutCell
                             id="Cell11"
                             align="LEFT"
                             width="100%">
                             <hbj:textView
                                 id="welcome_message"
                                 text="May the force be with you unknown user"
                                 design="HEADER1" />
                       </hbj:formLayoutCell>
               </hbj:formLayoutRow>
           </hbj:formLayout>
    </hbj:form>
.JAVA:
public void doProcessBeforeOutput() throws PageException {
         this.setJspName("myjsp.jsp");
      Form Reg_Form = null;
      FormLayout RF_All = new FormLayout();
      Tray Left_Tray1 = new Tray("TrayRules1");
       Reg_Form = (Form)this.getForm();
       RF_All = (FormLayout) this.getComponentByName("myLayout");
       for (int i = 1; i <= 3; i++ ) {     RF_All.addRow(); }
       Left_Tray1.setTitle("Sample Title");
       Left_Tray1.setWidth("100%");

       Left_Tray1.addComponent(Left_Tray1_text);
       RF_All.addComponent(2,1, Left_Tray1);
       Reg_Form.addComponent(RF_All);
That code don't display Tray in page...

Paul,
I suggest you not to add the your business logic in that auto generated file.
Instead you can have seperate java file or any Bean.
Since you are writing the logic for layout you can add the code in the jsp file
itself.
If you are using HTMLB Then keep the auto generated code in the jsp otherwise remove the code and keep the file as jsp meaning you use the html, javascript,
jsp code in the .jsp file itself.
you can add the java code in the jsp
<% String strName = "SAP"; %>
<sc ript>
al ert("<%=strName%>");
</sc ript>

I have solved moving the creation of the reference of the node element and the setting of elements inside the second for loop:
for (int i = 0; i < phaseSize; i++)
                      PhaseT phaseT = processT.getSequenceGroup1().getPhaseList().getSequenceGroup1().getPhase()<i>;
                      String phaseDesc=phaseT.getSequenceGroup1().getPhaseDesc();
                      String phaseId=phaseT.getSequenceGroup1().getPhaseId();
                      int subPhaseSize = phaseT.getSequenceGroup1().getSubPhaseList().getSequenceGroup1().getSubPhase().length;
                      for(int j = 0; j< subPhaseSize; j++)
                           SubPhaseT subPhaseT = phaseT.getSequenceGroup1().getSubPhaseList().getSequenceGroup1().getSubPhase()[j];
                           IPrivateRoadMapVIew.IPhase_subphase_tableElement tableElement = wdContext.nodePhase_subphase_table().createPhase_subphase_tableElement();
                           tableElement.setSubphase_desc(subPhaseT.getSequenceGroup1().getSubPhaseDesc());

<mx:Array id="arr">
    <mx:Object label="Flex"
      thumbnailImage="http:/someURL"
      fullImage="http://someURL" />
</mx:Array>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
</mx:Canvas>
This gives me an error
The prefix "mx" for element "mx:Array" is not bound
I need a root element here, but I cannot use mx:Canvas, what would be the best choice?
cheers
Luca

Hi Luca,
Try to put the Array inside your canvas rather than outside ...
<?xml version="1.0" encoding="utf-8"?
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Array id="arr">
    <mx:Object label="Flex"
      thumbnailImage="http:/someURL"
      fullImage="http://someURL" />
</mx:Array>
</mx:Canvas>
Why you dont want to use mx:Canvas as root tag of your component.. ?? However which ever component you use try to put the <mx:Array/> inside your root tag of your component, otherwise you will be thrown the same error as mentioned. The error occurs as the the compiler doesn't recognize the namespace mx for the array since you declared it outside the root tag of your component.

Remove element from array

hi
if i have an array
eg
int[] array = {4,2,1,2,1};
how to i remove the index 2 from it and create a new array?
thanks

You can't remove the element--an array's size is fixed at creation.
If you want a new array, create a new one that's one element smaller, then use System.arrayCopy to copy the elements you want to keep.

GeneralException Node(( Context path of node ): cannot bind or add element,

Hello all,
Stack trace :
GeneralException Node((<Context path of node>): cannot bind or add element, because it is already bound to a node
I am trying to upload data from excel file in web dynpro context.In the process, when I create and add an element to the node which I want to populate with excel data, it throws the above mentioned exception.
Any idea as to wht is causing the problem ?

Hi,
GeneralException Node((<Context path of node>): cannot bind or add element, because it is already bound to a node
It seems that its a mapped node, try to bind or addelements at the source.
Ex: If this node is mapped from controller to view try to add elements in contoller instead of doing in view.

How can i retrieve missing element in array

how can i retrieve missing element in arrays if array length is exceeded

Not sure about what the question means, but could it be that OP is not aware that the first element in an array is at index 0 (not 1) ?

ContextException : cannot bind or add element

Hi all,
I can't find an answer to my problem.
Hope you'll be able to
Here are the facts :
Context :
I'm currently creating a TeamViewer for Managers to be able to select the employees they manage.
For that, I have a table which lists them all, displaying their infos in specific columns.
Both columns and data are dynamic and are specified in the SAP back end.
I use the following bapis to get these informations :
- HRWPC_RFC_GET_COL_INFO (returns columns informations)
- HRWPC_RFC_GET_OBJECTS (returns employees personal numbers -> pernr)
Fact is the second one doesn't return as much informations as needed.
So I have then to call a third bapi :
- MYBAPI_USER_INFOS (return informations about an employee)
which, from an employee pernr, returns a lot more informations about him.
Fact is I manage to use efficiently both first bapis, so I get columns and pernr data.
Then I would like to get in a context node the list of enhanced informations of the employees, which is mapped to my view context and applied to a dynamic table.
My problem :
While adding programmaticaly the columns to my context node, I get the following exception : "com.sap.tc.webdynpro.progmodel.context.ContextException: Node(TeamViewerApp.MainViewColumns): cannot bind or add element, because it is already bound to a node" error.

Any help will be really appreciated
Thank you for your time!

HI,
com.sap.tc.webdynpro.progmodel.context.ContextException: Node(HrChiefRedressalView.Ctx_FilteredOutput): cannot bind or add element, because it is already bound to a node
Try to bind or add element from the source of the node instead of mapped one.
Ex:
Controller->View
If your node is mapped from controller to view. bind/add element should be done at controller level not at view level.
