Error using Richfaces Drag and Drop support in JSF 1.1 application

Iam using rich faces drag n drop support in my JSF application . The jsp works as expected but I get this weird exception while navigating through my pages.
Scenario : User logs into the application , from the home page ---> when the user click on a button he is navigated to the jsp which has the drag n drop support. This was working fine till , I have added a menu_incl .jsp inthe sub view . The code snippet is as shown below :
<body>
     <div id="wrap">
     <f:view>
     <f:subview id="menu">
          <jsp:include page="/search/incld/menu.incl.jsp" />
     </f:subview>
     <rich:dragIndicator id="indicator" />
     <h:form id="myfolder">
          <h:panelGrid columnClasses="panelc,panelc,panelc,panelc" columns="4" width="100%">
               
               <rich:panel style="width:133px">

                    <h:dataTable id="querytable" value="#{dndBean.queryList}"
                         var="query" binding="#{workSpaceBean.queryData}" >
                         <h:column>
                              <a4j:outputPanel style="width:100px;border:1px solid gray;padding:2px" layout="block">
                                   <rich:dragSupport dragIndicator=":indicator"
                                        dragType="Query" dragValue="#{query}">
                                        <rich:dndParam name="label" value="#{query.name}" />
                                   </rich:dragSupport>

                                   action="#{workSpaceBean.populateQuery}">
                                   </h:commandLink>
                              </a4j:outputPanel>
                         </h:column>

                    <f:verbatim></div> </f:verbatim>

Iam getting this error only when I include this jsp in the parent jsp :
<f:subview id="menu">
          <jsp:include page="/search/incld/menu.incl.jsp" />
</f:subview>
Iam including the same way in all other jsps of my application , they are all working fine expect for this jsp which has ajax components (rich faces drag m drop support components ) .
From the error I deduce that the view component is being generated twice , why is this so???
I would appreciate if some one coulkd guide me through this .... I hope I was able to explain my issu properly , please let me know if it is now clear

I've tinkered a bit with DnD before in the past. Actually, it's all related to the topic of Data Transfer. You have to provide a source and destination for the transferrable, and your transferrable object must provide the "data flavors" that it supports.
In theory it doesn't sound too hard, and it works reasonably well within a java application, but to be honest your time might be better spent simply implementing cut n' paste, which is easier. Cut n' paste doesn't require all the fancy UI work, but does the job reasonably well.
There's a DnD spec available on the documentation web-site, if you haven't already found it. I also discovered that the O'Reilly book (I think it's the AWT book, not the swing one) has a good chapter on data transfer that you might want to read.

Accessing param values using RichFaces Drag n Drop

Hello everyone,
I'm using RichFaces drag and drop support and I want to pass an additional parameter so that I can access it's value when processing the dragged/dropped object.
My JSP has:
<rich:dragSupport dragIndicator=":indicator" dragType="measure" dragValue="#{measure}">
       <a4j:actionparam name="operator" value="#{aggOp}" assignTo="#{SessionBean.tempAggOp}"/>
       <rich:dndParam name="label" value="#{measure.name} (#{aggOp})"/>
</rich:dragSupport>
<h:outputText value="#{aggOp}" style="font:11px arial;"/>On my backing bean method that processes the event, I can access the object's properties fine, but the param has a strange behaviour:
The first time I drag an object, the param value is null on the bean. The second time, it has the value it should have for the first dragged object, and so on.
Apparently the param value is being updated after the drop event method is called. Any ideas on how to change this please?
Thanks in advance,
~Ruben

To solve this problem I used <f:param> instead of actionParam:
On the drag support component:
<rich:dragSupport dragIndicator=":indicator" dragType="measure" dragValue="#{measure}">
                                                    <f:param name="operator" value="#{aggOp}" />
                                                    <rich:dndParam name="label" value="#{measure.name} (#{aggOp})"/>
</rich:dragSupport>     On the backing bean:
    //dropped item processors
    public void processDropSupportTable(DropEvent dropEvent) {
        if (dropEvent.getDragType().compareTo("measure") == 0) {
            SOLAPMeasure dragged = (SOLAPMeasure)dropEvent.getDragValue();
            FacesContext context = FacesContext.getCurrentInstance();
            Map requestMap = context.getExternalContext().getRequestParameterMap();
            String tempAggOp = (String)requestMap.get("operator");
            System.out.println("dropped: " + dragged.getId() + " named: " + dragged.getName() + " whose operator is: " + tempAggOp);
    }

I used to drag and drop newly loaded CD's from Recently Added to one of my iPod Classic playlists. I have no idea how to do this with the new version of iTunes. I thought perhaps checking Sync might give me a clue but it warned me Syncing would wipe conte

I used to drag and drop music loaded from CD's from the Recently Added folder to a Playlist on my iPods Classic. Can't see how to do this with new iTunes version. Probably need to sync somehow but when I checked on Sync it warned me it would wipe out my iPod contents. Don 't know why Apple makes something that used to be simple so difficult. Can't even figure out how to display both my library and iPod contents on same screen.

Hey joshuafromisr,
If you resintall iTunes, it should fix the issue. The following document will go over how to remove iTunes fully and then reinstall. Depending on what version of Windows you're running you'll either follow the directions here:
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP

or here:
Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7

Any idea how to fix this BUG please???
Am using a Mac Pro Quad-Core Intel Xeon

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

I used to drag and drop photos into pages. Recently updated to iPhoto 9.4.3 and now Pages doesn't recognize the photo?????

I use iWork Pages '09 to create my images. I normally drag and drop photos from iPhoto directly to Pages.
With iPhoto 9.4.3 I now get an error: " The media can't be used because you don't have access privileges or because it has no content or is corrupt". This doesn't happen with every photo from the same event and doesn't get corrected after running 'Repar Permissions'. I can Export to desktop then drag to Pages but that is stupid. What's up???

With iPhoto 9.4.3 I now get an error: " The media can't be used because you don't have access privileges or because it has no content or is corrupt".
This looks like previews of some of your photos are missing or corrupted. Did you run a cleaning application, like "clean my mac" or move your iPhoto Library? Where do you store your iPhoto Library?
I'd try to repair the database or rebuild the iPhoto Library in addition to repairing permissions with the iPhoto Library First Aid Tools. Launch iPhoto with the command and options-key ⌥⌘ held down at the same time to get to the First Aid Tools.
Back up the iPhoto Library before you try rebuilding.

Error occurs when dragging and dropping a Video Transition

Hi there.
This is my first post here, as I have only recently upgraded to Premiere Pro CS5 from a very old version. I am running into a big problem with video transitions. Whenever I try to drag and drop a transition onto my timeline, Premiere crashes and says "Sorry, a serious error has occurred that requires Adobe Premiere to shut down..." Then the screen just hangs there and I need to do a Ctrl+Alt+Del to close the program. Please note that crossfades work with no issues whatsoever, and I have not encountered any other errors. Any ideas?
Here are some of the specs of my system:
CPU: Intel Core i7 950 @ 3.07 GHz
Video Card: NVIDIA GeForce GTX 470
OS: Windows 7 64-bit
RAM: 12 GB
I have 4 drives with the programs and files allocated per the suggestions in this forum.
Thanks,
Dave

Here would be my shotgun approach to your issue: Try adding effects on different footage. If no crash, the footage may be corrupt.
Try a new project with the same footage. If no crash, the project may be corrupt.
If above actions still produce a crash, trash prefs. Prefs may be corrupt.
You also may have bad RAM. Run a RAM-test app.
Still crashing? Re-install the application. The app may be damaged.
Sorry I don't have a firm answer, but you may need to seek and destroy, using process of elimination.

Error message when dragging and dropping images to album

I recently installed the Elements 12 upgrade on my MacBook Pro. My previous version was Elements 10. When I try to add new images to my existing albums by selecting, dragging and dropping them into an album the operation does not work and i get an error message "Error Applying Keyword Tag(s)"

Thanks for your reply Andaleeb,
When you look at the numerous discussions on the PSE forum on this Organizer window issue it's not just a problem I had (Thread 14444851) but other users who have Elements 10, 11 and 12 are experiencing similar problems. There appears to be a serious compatibility problem with OSX 10.9.2 and these versions of PSE. Although my issue was fixed by your support staff, the fact that many other users are experiencing this issue points to the need for a universal fix applicable to all Mac users. There is a lot of frustration out there among Mac users and Adobe needs to deal with this problem.
I am really surprised that on all the other discussion posts on this issue, there is not a single comment or response from Adobe staff! Given the lack of response from Adobe, it appears that the Adobe policy is to sit back and let the Mac users determine their own solutions.
Please pass this post on to your management so that corrective action can be initiated.
Thanks for your help.

Error 1009 when dragging and dropping

Hello All,
I have a problem in a large application with dragging and dropping between datagrids. I created a simple example of the issue below. Basically, when I press the button I get a pop-up with 2 datagrids. When Initially try to drag an item from the source grid to the destination grid I get a serious of errors:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
..etc
If I then try and drag and drop again, it works without error. Can anyone shed light on this? Code below:

I can confirm this error. I'm using Firefox, Windows Vista, Flash Player 10, SDK build 11250. There are two error boxes that appear when you try to drag an item on the first attempt and on successive attempts (but only if you drag over the destgrid, then back to the srcgrid and then back again to the destgrid). It's gotta be a bug, here are the stack traces:

How to Create Table Using Column Drag and Drop Feature

Hi:
I am new to Oracle SQL dev Data Modeler tool and would like to know if there is a way to create a new table by re-using the existing columns or column groups. The idea is to maintain consistency and save table design time. If columns created previously can be re-used and require drag and drop of column in the right pane, then only new columns need to be manually created.
Any thoughts on this will be appreciated.
Thanks!

Hi Kent
I checked out the video and tried it in Oracle designer, it works and works great!
My other question is that I may have several set of columns that I may want to group depending on the table requirements. Can I have multiple templates and choose which one to apply to?
Also, how do I choose the table where the table template needs to be applied. As I may be interested in applying the table template to selected tables only.
Thanks

I use to drag and drop an web address into a link toolbar, can't seem to figure out how to do this...?

I just upgraded to Windows 7 and with it I got the latest Firefox. There is nothing like learning 2 things at one time. On my old XP and 3.? all I have to do was drag and drop a web address into a link toolbar. Saving all my frequent visited or just sights I want quick access to, to a toolbar quick button. I have been playing with this for days and decided to try this Forum. I did find the Bookmark toolbar, but cant seem to figure out what is if for or if you can drop into it. When I right click it and Customize, it shows me add on buttons, but nothing to do with web addresses or alike...
Bottom line; I want to be able to drag and drop a web address into a toolbar for recall latter and be able to edit the address with a right click at a latter date in necessary...
Thanks, Mike

You can drag and drop the favicon also known as the [https://support.mozilla.com/en-US/kb/Site+Identity+Button site identity button], at the left hand edge of the location bar onto a toolbar to bookmark the site.

I can't figure out what kind of Error this is!? Can someone help me? How can i solve this Problem!?

Ihre Objekte sind zu mir gehören!!! LOL I took a year of German, stayed in Berlin for a month and all I can remember is... Scheiße!
Ok, so about this problem of yours... it's been brought up in this forum before -- Error 1009 on drag/drop events within lists when those lists are not in the main application domain (whether it's a pop up or some module). See the post here:
http://forums.adobe.com/message/2354888#2354888
A bug was supposed to have been created for this issue. If not, I recommend you submit a new bug and reference yours and the other post's test case. Also worth asking the other poster if they came up with a workaround.
My hunch is that whatever is tripping you up is internal and non trivial (i.e. I have no idea why this is happening and have no obvious workaround for you ). Best o luck,

Can you Cancel "acceptDragDrop()" using Manual Drag-and-Drop?

I have an AdvancedDataGrid (ADG) with manually drag-and-drop
functionality built in. The user can only drag-and-drop within the
one ADG. I do this in order to validate which items can be dragged,
and where they can be dropped. I have run into one problem,
however. In my override of dragEnterHandler(), I call
DragManaged.acceptDragDrop() if the user drags an item over a valid
item. However, if they don't drop the item there, and continue to
drag the item around the ADG, and roll over an item that is not
valid, there's no way to cancel the drop.
Does anyone have any suggestions?

Thanks for the updates.

I am used to "drag and drop" content from my computer to my old i-pod. With the new i-tunes, I can't seem to do that. Any suggestions?

Only Audio CDs will show up in iTunes.
This is new to me because I am used to importing and making copies from my playlists.
I don't follow. Would you explain this a bit more?
