Delete selected elements??

Hi all,
How do I delete selected elements in a node? Let say I want to delete element index 2. How do I do it? Thanks.

Hi.,
Get the selected Element or selected Index.,
now read the internal table in node using get_static_attributes_table method.,
loop the internal table
count = count + 1.
if count = selected index.
esle.
append internal table to final internal table (itab-fin).
endif.
endloop.
now bind_table( itab_fin ). " now the selected element will not appear in the node.
you can also use remove_element method to remove selected elements
hope this helps u..
Thanks & Regards,
Kiran

Delete node elements

I have created 5 elements of a node . I want to delete nodes. But it is giving error .
Context
          sample (node )    [ cardinality 0...n , selection 0..1 ]
                      name (attr)
                      number(attr)
code :
public void onActioncreate(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActioncreate(ServerEvent)
    for(int i=0;i<5;i++){
         IPrivateClearnodeElements.ISampleNode node =wdContext.nodeSample();
         IPrivateClearnodeElements.ISampleElement ele = node.createSampleElement();
         ele.setName("Name "+i +" : " );
         ele.setNumber(i+"");
         node.addElement(ele);
    //@@end
public void onActionclear(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionclear(ServerEvent)
    wdComponentAPI.getMessageManager().reportSuccess(wdContext.nodeSample().size()+"");
    for(int i=0;i<5;i++)
          try{
          wdContext.nodeSample().removeElement(wdContext.nodeSample().getSampleElementAt(i));
          wdComponentAPI.getMessageManager().reportSuccess("Deleted : "+ i+"");
          catch(Exception e)
               wdComponentAPI.getMessageManager().reportSuccess(e.getMessage()" : " i+"");
    //@@end
output :

Deleted : 0
Deleted : 1
Deleted : 2
Index: 3, Size: 2 : 3
Index: 4, Size: 2 : 4
Why it is not able to delete the last two node elements ????????????????//
Also any other way is there to delete elements of the node?
Srini

Hi srinivasa,
You have used the code to delete the element
for(int i=0;i<5;i++)
try{
wdContext.nodeSample().removeElement(wdContext.nodeSample().getSampleElementAt(i));
wdComponentAPI.getMessageManager().reportSuccess("Deleted : "+ i+"");
catch(Exception e)
wdComponentAPI.getMessageManager().reportSuccess(e.getMessage()" : " i+"");
Now.. See getSampleElementAt(i) method returns the element of i th element. On that case you have to use
getSampleElementAt(0). In that case it wiil return 0ih element end 0th element will be deleted. After deletion the 0th element 1st element will move to the 0th position.
So. in that way you can delete all the elements.

Get selected elements from a table

Hi all,
I have a requirement like i m enhancing standard component in that i have added one button on click of that i want fetch the selected line item from the table ( which is a normal table). selection mode is auto.
i tried with the following code.
DATA:lr_element TYPE REF TO if_wd_context_element,
lv_index TYPE i.
*--Get selected element
lr_element = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
****Here itself its throughing dump because lr_element is initial***************
*--get selected element index.
lv_index = lr_element->get_index( ).
can any one help me what is the wrong.. else suggest me how to get the selected elements from a table....
Thanks in advance.

*--Get selected element
lr_element = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
if lr_element is bound.
lv_index = lr_element->get_index( ).
endif.
Instead you can directly read the node if that row is a lead selected one.
lo_node = wd_context->get_child_node( name = 'EMP' ). "Emp is node name
lo_ele = lo_node->get_lead_selection( ).
or
lv_index = lo_node->get_lead_selection_index( ).
where is the above code written..is it written in OnLeadSelect event of the TABLE..
can any one help me what is the wrong.. else suggest me how to get the selected elements from a table....
As the selection mode is Auto there is no multiple selection..hence try to use the lead selection only.

You do the opposite of how you got them on your phone, you unsync the pics using iTunes.

How to delete selective data in a cube

Hi all,
Can any one tell me, how to delete selective data in a cube. For example if i want to delete data corresponding particular Matrial Id or particular Customer ID (say C400) ? And even deleting the data based on particular Request numer.?
Sandy.

Hi,
RSMO > Infocube > Manage > contents tab > selective deletion
Then define your selections for deletions (Matrial Id or particular Customer ID (say C400)).
Request based deletions can be done directly from Request tab.

HOW TO DELETE DUPLICATE ELEMENT IN A VECTOR

Hi everybody!
If I've a vector like this vectA={apple,orange,grape,apple,apple,banana}
and I want final result be vectB={apple,orange,grape,banana}.
How should I compare each element in vectA and delete duplicate element. Like here duplicated element is apple. Only one apple remain in the vectB.
Any help,
Thanks.

Hello all. Good question and good answers, but I would like to elaborate.
To begin with, you specifically asked to map the following:
{apple,orange,grape,apple,apple,banana} ==> {apple,orange,grape,banana}
Both of cotton.m's solutions do NOT do this, unfortunately. They are both useful in particular cases though, so think about what you're trying to do:
cotton.m's first solution is best if order does not matter. In fact, as flounder first stated, whenever order doesn't matter, your most efficient bet is to use a Set instead of a List (or Vector) anyways.
Set vectB = new HashSet(vectA);This code maps to {banana, orange, grape, apple}, because HashSets are "randomly" ordered.
cotton.m's second solution is good if you want to impose NEW ordering on the List.
Set vectB = new TreeSet(vectA);This code maps to {apple, banana, grape, orange}, because TreeSet uses alphabetical-order on Strings by default.
java_2006, your solution is the most correct, but it's a little verbose for my taste :)
more importantly, the runtime-efficiency is pretty bad (n-squared). calling Vector.contains performs (at worst) n comparisons; you're going to call it n times! Set.contains usually performs 2 comparisons (constant, much better), so I suggest you USE a Set to do the filtering, while still sticking with your good idea to use a List. When the ordering is "arbitrary" (so can't use TreeSet) but still relevant (so can't use HashSet), you're basically talking about a List.
I think saving A LOT of time is worth using A LITTLE extra space, so here, let's save ourself some runtime, and some carpal-tunnel.
import java.util.*;
class Foo {
     public static void main(String[] args) {
          String[] fruits = {"apple","orange","grape","apple","apple","banana"};
          List     l = Arrays.asList(fruits),
               m = filterDups(l);
          System.out.println(m);
     // remember, both of the following methods use O(n) space, but only O(n) time
     static List filterDups(List l) {
          List retVal = new ArrayList();
          Set s = new HashSet();
          for (Object o : l)
               if (s.add(o))
                    retVal.add(o);     // Set.add returns true iff the item was NOT already present
          return retVal;
     static void killDups(List l) {
          Set s = new HashSet();
          for (Iterator i = l.iterator(); i.hasNext(); )
               if (! s.add(i.next()))
                    i.remove();
     // honestly, please don't use Vectors ever again... thanks!
     // if you're going to be a jerk about it, and claim you NEED a Vector result
     // then here's your code, whiner
     public static void mainx(String[] args) {
          String[] fruits = {"apple","orange","grape","apple","apple","banana"};
          List l = Arrays.asList(fruits);
          Vector v = new Vector(l);
          killDups(v);
          System.out.println(v);
}

How can I access the selected element of a DropDownByIndex-box?

Hi,
I want to create a WebDynpro with two web services. I created the first request with the first web service and the results are displayed in a DropDownByIndex-Box. Now the user should choose one of the results and I would like to use this for the request with my second web service. How can I access the selected Element of a DropDownByIndexBox in the Code?
Thank you!!
Julia

Hi Julia,
when user select one element in drop down it automatically set lead selection of node binded to dropdown.
For example if you bind a dropdown to node myNode with value attribute myAttribute the lead selection of node myNode is set in the position of element choose from user.
So to take this chooised element use this code:
wdContext.currentMyNodeElement.getmyAttribute()

Delete of Element in Form for COPA line item report

Hello
I would like to change a form used for a COPA line item report - delete an element, which has been included for years. Unfortunately I got message, that 'You cannot delete, because element xxx is dependent'.
If I insert a new element if have no problems to delete it afterwards.
Can anybody help me?
Thanks in advance.
Best regards
Søren Kirch
LOGSTOR A/S

Hi,
To my knowledge, you cannot delete the element until you assign the new one in the form if only single element is assigned.
In case anymore element is there, there can be possibility this element is taken into consideration for making formula.

Error Rendering SELECT Element in Safari Under iOS (iPhone & iPad)

Hello,
Our website contains three SELECT elements that are not rendering properly under Safari, iOS 4.2 on both an iPhone and iPad.
If you load http://demo.campusguides.com in a normal browser (Chrome, FF, non-mobile Safari) you will see that the three "Browse By" boxes at the top of the page each contain text that you can select using your mouse. Each of those boxes is actually a SELECT element and each piece of text is an OPTION within that SELECT box. We have set a SIZE property on the SELECT element that allows the user to see more than one OPTION value at a time. Here is the W3C page that mentions the SIZE option for SELECT boxes - http://www.w3.org/TR/html401/interact/forms.html#adef-size-SELECT.
On all the browsers I have tested the list displays properly, meaning that you can see multiple OPTION values at once as well as a scroll bar (when needed) that allows you to scroll up and down the list. On iOS Safari however the list is displayed as an empty box with no OPTION values visible to the user. If the iOS user clicks the SELECT element they are taken to the normal SELECT interface for Safari which does work fine, but without any content displaying in the box to begin with, I don't think many users would know they can / should click that element.
So basically I think this is a bug, and that iOS Safari should either render that SELECT element with the OPTIONS visible to the user, or it should ignore the SIZE property and render that element like a "normal" SELECT menu where only one option is visible at a time.
Thank you!

Firefox 33 HTML select elements do not display correctly

HTML form <select> elements do not display options correctly in Firefox 33.
For example:
<select id="field_4" class="mainForm" name="field_4">
<option value=""></option>
<option value="submitted"></option>
<option value="pending"></option>
<option value="discarded"></option>
<option value="all"></option>
</select>
should display a drop down with 5 elements (first one blank) but no elements at all are displayed.
The bounding box does not seem to be computed correctly so no options display.
I have observed this issue on multiple pages. These pages displayed correctly in older version of Firefox and they display correctly under IE. The problem occurs with no addons or additional themes installed. The problem does not occur in SafeMode so I suspect that it is theme related but the Default 33.0 theme is the only installed theme and it cannot be disabled outside of SafeMode. I tried installing and changing multiple themes without success. The problem persists after restarting Firefox and after rebooting the computer and even after uninstalling and re-installing Firefox.
I can supply a screen shot if needed.

You can try to disable hardware acceleration in Firefox.
*Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.
*https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration
If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)

Deleting selected record in Dynamic Internal table

Hi Friends,
I want to delete selected row from a dynamic internal table. The selected entry should be deleted from Adobe and as well as Webdynpro abap.
Kindly help me how to solve this problem.
Thanks in advance.
Regards,
Phani.

Hi Matthias,
Thanks a lot for responding.
In my adobe i kept a check box to delete the record. It should delete the selected ones. But right now, its deleting one by one.
I have coded following script for delete button:
IT_TIME_SHEET --> is my internal table
G_ROW_STATUS is the field to track the action performed.
var tlength = xfa.resolveNodes("IT_TIME_SHEET.DATA[*]").length;
for ( var i=0; i<tlength; i++
if(xfa.resolveNode("IT_TIME_SHEET.DATA["i"].FLAG").rawValue ==
1 )
IT_TIME_SHEET.DATA.instanceManager.removeInstance(i);
G_ROW_STATUS.rawValue = "DELETE";
In the Webdynpro abap following code I wrote:
    row_count = 1.
    FIELD-SYMBOLS <wa> TYPE zshr_time_sheet_time.
    LOOP AT it_time_sheet ASSIGNING <wa>.
      <wa>-srl_no = row_count.
      row_count = row_count + 1.
    ENDLOOP.
    last_row = <wa>-srl_no.
      DELETE it_time_sheet WHERE srl_no EQ last_row.
Suppose if two records checkboxes are selected I can loop at the internal table IT_TIME_SHEET in webdynpro and delete where checkbox is selected.
But problem is once user deletes records, adobe is deleting only one record and if i delete two records from webdynpro it looks like something wrong for the user.
Please help me how to solve this problem.

Phani.

Delete xml element not used in document

Hi,
If you have a number of texts tagged with an xml element and then delete the text, the element still exist in the structure.
You can see the element still connected to a text, by the blue diamond on the element symbol.
But i want do delete the elements that have no connection to texts, but cant find the right property to look for.
In Java script CS4.
Anyone knows?
/Mikael

If the (text) element is unplaced, its parentStory will be an XmlStory rather than a Story.
So try:
var elements = app.activeDocument.xmlElements[0].xmlElements.everyItem().getElements();
for (var i = elements.length - 1;i >= 0;i--){
if(elements[i].parentStory.constructor.name === "XmlStory"){
elements[i].remove();
This is untested. If you have tagged graphics frames it will need to be modified to not error on those.
