Drag and Drop via Data Control doesn't seem to bind input parameter.

Hi Everyone,
I've followed the 'how to drag and drop a webservice data control' excercise in my current application to bring back complex data on the basis of one parameter(appId). However, when running the application, the server logs indicate that 'The value of appId cannot be null'. I have definitely bound the appId to the requestIterator, and the button that calls the webservice has been bound accordingly too. The response tables have been bound to the responseIterator. The webservice definitely works, and brings back data as I've tested it with SoapUI for this appId.
Is there something I'm missing?
Any suggestions will be helpful.
Thanks,
Preethi.

Hi Sarojamaly,
According to your description, when you create a Data Source View in BIDS/SSDT, you can't see the tables in the pane. Right?
In this scenario, when creating data source, please make sure you select a correct data provider. For example, it you connect to SQL Server database, you should use
Native OLE DB\SQL Server Native Client. Then please test your connection to the data source.
If the tables still can't be displayed, please make sure you select proper database and the check tables existence in the database.

Issue : drag and drop from list control to tree control

Hi,
I was trying a drag and drop from list control to tree control. I have used some sample data to populate list and tree controls .
It is working fine . except one problem ..
Prob : when i drag an item to tree control .. it gets added .. now tree contains (X+1) data in list .. say X is the inital number of nodes in a tree node.
          now if i drag another item from list to last item in the tree node .. i.e at X+1 index. .. it throws null pointer exception.
I am considerably new in flex programming . looking for help from experts ..
Below is my code :

Drag and drop to other desktops doesn't work in Mavericks

I'm currently experiencing an issue with dragging and dropping files within Mavericks. It seems to work only within one desktop: from one window to another. However, when I want to drag something to another screen/desktop the dragged items become stuck on the other screen. I can only move them again when I go back to the original window I dragged them from.
It is not practical to drag and drop anything on the same desktop on my (little) 13" MacBook Pro. By the way, this happened after updating to Mavericks.\
Can anyone help me?
If you're experiencing the same problem, please click the thumb.

the splice() method accepts two arguments. the first is the (start) index of the element(s) you want to remove and the 2nd argument is the number of elements you want to remove. in your situation, you should be using:
bubbles.splice(currentIndexArray,1);

ITunes 11 and no ability to drag and drop via home sharing...

I can find NO way to drag and drop playlists via home sharing now with Itunes 11...any help appreciated.

PROBLEM SOLVED -
I found this on someone else's post on another website...
You have to sign into your home sharing with the SAME apple ID and password on each computer. It's common for people to want to put their individual/own ID and password on "their" computer, but that is not correct to fully authorize home share. Even on someone else's machine on your network, you still use the same apple ID and password for all computers you want to home share with. The other computer isn't getting access to your account or anything like that. You just have to use the same ID and password on each machine and that will enable home share among all home share computers that logged in with that ID and password. Otherwise you will just be able to see and stream the other computer's content, but you will not be able to copy it over or drag and drop.

Drag and Drop For String Control

Hello all,
I attached a example program, where I did not see event for String Drag Starting?.
Is it normal.
I placed a break point and I tried to start draging, but I hvn't seen the event.
Please let me know, if this is normal.
Thanks,

Drag and Drop -String.vi ‏45 KB

Extract from the LV help for this event :
Generated when you start a drag
from a listbox control. Use this event to signal
when a drag and drop operation begins from a specific control. This
event is generated only when LabVIEW begins a drag and drop operation on
a listbox control. You can use the Start Drag method to begin a drag from other controls.

******DataControl Drag and drop -method return parameter issue!!!******

Hi,
It is a basic DataControl question where I am facing some issues due to this.
I have created the DataControl form java webservice and using that DC in my ADF application. When I drag and drop my Data Control RESULT in my UI and select some specific output structure (Table or form or etc), it is pop-up the window with all the return parameters where I can enter the lables and hitting OK button.
While hitting OK button some times it is pop-up the next window where I can see the DataControl name on the top and the method input parameters list on the bottom of the window and I can enter the value for my input fields. But very few times I am getting this 2nd window popup. Not every time where after hit the OK button in the first window directly it is creating the table / form in the UI.
But I need this 2nd window to be popup inorder to carry forward my input parameters binding across my application. Please help me why am I not getting that method input list sometimes. Or is there any other file I can edit and set the method input parameter binding?? This is really helpful to solve one of my major project issue. Help plzzzz...
Thanks

Arun & Puthanampatti
Thanks for the help. Yes I did the same and now I could able to carry forward my input param values from first page to 2nd and 3rd pages where the first page holding method input parameters via DataControl and the 2nd and 3rd pages holding the DC method;s return params. Can you please let me know how to set the new value for the input parameter mapping from 2nd to 3rd page.
*Ex: In first page have 2 input parameters values set to:(UserID1 = #{pageFlowScope.arg0} & UserID2 = #{pageFlowScope.arg1}). I am navigating to 2nd page where I am displaying the userSearch result it may be display more than 1 user. Now I am navigating to 3rd page by selecting any one of the user ID and want to display that selected user details in the 3rd page. Here I am using the same DataControl method result at 2nd and 3rd page.*
*So I want to set the selected userId value to #{pageFlowScope.arg1} before I navigate to 3rd page. Please help me how to change/set the value to the #{pageFlowScope.arg1}. This will solve my major issue. Thanks in advance.*
Thanks

Drag and drop data object not working in jdev 11.1.1.7

I am trying to do quote process lab and faced this issue.
When defining the user task parameter in jdev 11.1.1.7 i am not able to drag and drop the data object in parameter list section.

Infact i am trying to create a simple BPMN projoect but it doesn't allow the data object to be drag and dropped in the parameter list.
This same thing was working fine for me in Jdev 11.1.1.6,Is there a bug in jdeve 11.1.1.7 ? Has anyone tested with the latest release?

How do I move photos from iphoto to imovie trailer? It says just drag and drop but it doesn't take them.

Macbook Pro imovie 11 trailer says to "just drag and drop photos" but it doesn't work????

You cannot put photos in a trailer. They are designed for videos.
However, there is a way around this.
Go to the Project Library view. Select your Trailer. Now, click FILE/CONVERT TO PROJECT.
Now you can add photos.

Drag and drop Images into Multiple Targets

Hello,
I want to alter the NI example "Drag and Drop - Multiple Data Types to Start Drag" to use multiple image Targets. The current VI only allows for dropping image into a single Target. I want to duplicate the target window a few times, in order to drop different images into each different Target. I can't seem to figure out how the VI recognizes and differentiates the Targets.
Thanks,
Labview 2009 SP1

Hello,
Please see attached... That's a simple way to perform what you need : each target is handled in the same event case (the target is differentiated by using control refnum).
Hope this helps,
J.

Itunes 11.1.4 won't drag and drop for ios 5.0.1

I have an older iPod touch running 5.0.1 and have ALWAYS manually managed the music on it. I recently updated itunes to 11.1.4.62 and now the 'drag and drop' function in itunes doesn't work. I have verified that the 'manually mangage music and videos' is checked. I really don't want to upgrade the ios as I don't need the newer features. I simply use this for music. Is this a bug with the latest itunes?

used a different computer running 11.0.5.5 and that worked. I guess this is a new 'feature' with 11.1.x?

Widget, Drag and Drop from palette not working.

Hi All,
I am trying to create a Widget using Eclipse and SAP Widget Tool.
I was working on a simple widget creation from a custom widget template.
The drag and drop option from palette doesn't work in my eclipse even after SAP widget tool has been installed.
Please suggest.
The configurations are.
Eclipse - 3.4.2 ganymede
Yahoo Widget Engine - 4.5.2
jdk - 1.6.0_14 (latest one).
Please help.

I had to reinstall eclipse.

Still no drag and drop between tabbed documents

Working with multiple documents opened at the same time is my everyday workflow and I'm sure I am not alone.
When Adobe introduced tabbed view it was finally a solution to messy multiple opened documents but they omited the biggest advantage in this workflow which is drag and drop of object from one to doc to the other.
In order to do so you have to go to Arrange button (CS5) or Window>Arrange (CS6) and choose to tile or float all documents. That is stupid and inefficient.
What we need is to grab a layer and drag it onto a another doc tab and Photoshop should switch to that tab immediately. You can drag and drop between separate Illustrator and PS files but you can't drag and drop within PS which doesn't make any sense.
Copy and paste is just as not as quick solution as drag and drop.
And while you at it why not make empty space after tabs double clickable to get open document window, kind of like when you have no file opened you can double click the gray area.

I keep tagging my agreement to this everytime I see it requested - from multiple users, including myself.
Dragging from the layers panel seems a much more logical method to me. What's really frustrating was that we had this in CS4, and it was removed in CS5 and is still absent in CS6.

Drag and Drop with a response in Flash..please help

Hi
I have just started with flash and actionscript3 about 5 weeks ago. I'm in my first year uni and I have a drag and drop assignment (for a kindergarten class). Its "little Red Hen" and they have place the correct picture in right holder.
I have gotten the drag and drop working but I can't seem to figure out how to display a tick when they have place it in the correct holder.
Please help....
This is my script (it may seem messy...still new)
import flash.events.MouseEvent;
/*Mouse Event that ensures the function of hen movieclip to start dragging
when mouse is pressed*/
hen1_mc.addEventListener(MouseEvent.MOUSE_DOWN, dragStart);
hen2_mc.addEventListener(MouseEvent.MOUSE_DOWN, dragStart);
hen3_mc.addEventListener(MouseEvent.MOUSE_DOWN, dragStart);
hen4_mc.addEventListener(MouseEvent.MOUSE_DOWN, dragStart);
hen5_mc.addEventListener(MouseEvent.MOUSE_DOWN, dragStart);
hen6_mc.addEventListener(MouseEvent.MOUSE_DOWN, dragStart);
function dragStart (event: MouseEvent):void
    event.target.startDrag();
/*Mouse Event that ensures the function of hen movieclip to drop
when the mouse button is realeased with Condition statement, if
hen = holder, hen snaps into place*/
hen1_mc.addEventListener(MouseEvent.MOUSE_UP, dragStop1);
function dragStop1 (event:MouseEvent):void
    hen1_mc.stopDrag();
    if (hen1_mc.hitTestObject (holder1_mc)==true)
        hen1_mc.x=holder1_mc.x;
        hen1_mc.y=holder1_mc.y;
hen2_mc.addEventListener(MouseEvent.MOUSE_UP, dragStop2);
function dragStop2 (event:MouseEvent):void
    hen2_mc.stopDrag();
    if(hen2_mc.hitTestObject (holder2_mc)==true)
        hen2_mc.x=holder2_mc.x;
        hen2_mc.y=holder2_mc.y;
hen3_mc.addEventListener(MouseEvent.MOUSE_UP, dragStop3);
function dragStop3 (event:MouseEvent):void
    hen3_mc.stopDrag();
    if(hen3_mc.hitTestObject (holder3_mc)==true)
        hen3_mc.x=holder3_mc.x;
        hen3_mc.y=holder3_mc.y;
hen4_mc.addEventListener(MouseEvent.MOUSE_UP, dragStop4);
function dragStop4 (event:MouseEvent):void
    hen4_mc.stopDrag();
    if(hen4_mc,hitTestObject (holder4_mc)==true)
        hen4_mc.x=holder4_mc.x;
        hen4_mc.y=holder4_mc.y;
hen5_mc.addEventListener(MouseEvent.MOUSE_UP, dragStop5);
function dragStop5 (event:MouseEvent):void
    hen5_mc.stopDrag();
    if(hen5_mc.hitTestObject (holder5_mc)==true)
        hen5_mc.x=holder5_mc.x;
        hen5_mc.y=holder5_mc.y;
hen6_mc.addEventListener(MouseEvent.MOUSE_UP, dragStop6);
function dragStop6 (event:MouseEvent):void
    hen6_mc.stopDrag();
    if(hen6_mc.hitTestObject (holder6_mc)==true)
        hen6_mc.x=holder6_mc.x;
        hen6_mc.y=holder6_mc.y;

Ok so I figured it out, thank you Ned.
I have made the tick_mc alpha 0 in the beginning of the script and then in my conditional I have made the alpha = 100
So it works...yay!
Now all I have left, if the piece is placed in the wrong holder then it needs to go back into its orignal position.
I have tried
Written above the script
var startX:Number;
var startY:Number;
then just below my dragStart code
startX = event.target.x = startX;
startY = event.target.y = startY;
then after each if statement I placed an else statement
else
      hen1_mc.x = startX;
      hen1_mc.y = startY;
Its clearly not working, please could you tell me what I am doing wrong?
thank you

Trying to run an older perl drag-and-drop program

At work we have a perl program that does a wonderful job of transforming a pre-edited (with tags) text file into an html document ready for the web including lots of external references to technical journals.
This was written eight or nine years ago in the Mac Classic days. There are three files. One is called formatter9. This has a camel icon with a circle with a line through it.
Then there is one called formatter9.pl and one called f9.template. The template is referenced in the formatter9.pl. I go into formatter9.pl and change the month each time before we use it at least 40 or 50 times during the course of a week.
This drag and drop application worked fine with Classic OS 9 loaded on PPC Macs, but not on Intel Macs.
I am able to run it on an Intel Mac with OS X 10.5 in terminal with an input file (called, for example, filename.txt) by entering:
perl formatter9.pl filename.txt
It would be nice to get this to work as a drag-and-drop in OS X, though. I've picked up a perl book, but it's new to me and I don't work with any techies.
My thought is that it might be as simple as changing the first few lines of code in the perl script. They are:
use strict;
my $isDroplet = 0; # 0=false, 1=true # use droplet for filter to be used by cgi
my $DEBUG = 1;
my $template = "f9.template";
my ($inText) = @ARGV; #$isDroplet?@ARGV:("something-esp.txt");
Would someone know if there might be a simple change to this code to make it work in OS X? If not, where else might I go to look for an answer?

Wait a minute. You are editing the script 40 or 50 times each week? Instead of worrying about making it drag and drop, change the code to accept a month as a parameter. Then just run it from the terminal with two parameters. Then use Automator to make it drag and drop and prompt the user for a month to select.

Drag and Drop via Data Control doesn't seem to bind input parameter.
