get the key of node of hierarchical Viewer in backing bean

Hi all



I am using jd 11.1.1.4

I have a hierarchical Viewer in my web page, which shows the employees in a company.

When I select a node and press the Add button, I want to add a node to the selected node level.

How can I get the details of the node selected in my grain of support

I used this code to get the key of the selected node

This.HV1.getSelectedRowKeys)


but this still gives null values

Please tell me how to do this

You don't do that in the seelctionlistener

{} public void nodeSelected (SelectionEvent selectionEvent)
UIHierarchyViewer hv = selectionEvent.getSource ((UIHierarchyViewer));
RowKeySet addedSet = selectionEvent.getAddedSet ();
Iterator i = addedSet.iterator ();

Model TreeModel (TreeModel) = hv.getValue ();
model.setRowKey (i.next ());

Object, selectedNode = model.getRowData ();
Then mount the selected node for the specific type of model tree
in this example, it's a unique selection model, so you have to get the single rowkey in the selection test

Note that the selectionEvent is org.apache.myfaces.trinidad.event.SelectionEvent
//...
}

    I can read only half of my product key due to wear, but I need to reinstall xp on my hard drive again. How can I get the key?

    If you can still boot your old disk, you can use a program such as one of them:

    KeyFinder: <> http://www.magicaljellybean.com/ >
    Belarc Advisor: <> http://www.belarc.com/free_download.html >

    to read the key out of your old system.

    Also note that if you have a system OEM and the OEM installation disks, the key can be incorporated in the installation discs and can not be necessary when your reinstalling Windows.

  • I did a restore of windows xp home 64 bit but did not reteive mny registry key. How can I get the key?

    I did a restore of windows xp home 64-bit but not recover my registry key.  How can I get the key?

    There is no such thing as Windows XP 64-bit Edition.  OEM machines are supposed to have a sticker with the product key on the computer somewhere.  You never did a full backup or an image of the disc on another drive?  If so, the key can be retrieved from the backup or image.

    I try to install vista on my laptop but a letter of the key is not visible, all the other parts are very well including the serial code, is there another way to get the key of the other information? The laptop currently has non-OS I've tried to reinstall.

    Thank you

    Product keys are bit-agnostic - they don't care if it's 32-bit or 64-bit.

    However, cannot legally use the recovery disk from one computer to a different constructor machine - as other licenses are not properly paid..

    There is nothing nonetheless to try all possible variations on the absence of character (there are only 25, after all the )

    Other than that, your best option is to contact the manufacturer and order a set of recovery disc for the machine. I do no download available for Vista with SP2 - but you can download Vista with SP1 and create the disc.

  • only get the key of the 'targetLayers' of 'Dcmn"descriptor

    Hi, I work with documents of very large, with many layers, and I have a problem when trying to get the key 'targetLayers' of the descriptor "Dcmn" Photoshop building histograms and it takes a lot of time, only to get selected... layers: () I know that there is the putProperty method, which works great for layers ('Lyr') or the Application ('capp') , but does not seam to work with documents

    Done, someone has an idea on how to get only the 'targetLayers' key?

    This is the code to get the index of selected layers:

    function getSelectedLayersIdx(){// get the selected layers index( positon in layer editor)
         var selectedLayers = new Array;
         var ref = new ActionReference();
         ref.putEnumerated( charIDToTypeID('Dcmn'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
         var desc = executeActionGet(ref);
         var add = 1;
         if(hasBackground()){add = 0}
         if( desc.hasKey( stringIDToTypeID( 'targetLayers' ) ) ){
              desc = desc.getList( stringIDToTypeID( 'targetLayers' ));
              var c = desc.count
              var selectedLayers = new Array();
              for(var i=0;i<c;i++){
                   selectedLayers.push(  (desc.getReference( i ).getIndex()) + add);
              }
         }else{
              var ref = new ActionReference();
              ref.putProperty( charIDToTypeID('Prpr') , charIDToTypeID( 'ItmI' ));
              ref.putEnumerated( charIDToTypeID('Lyr '), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
              srs = hasBackground()?executeActionGet(ref).getInteger(charIDToTypeID( 'ItmI' ))-1:executeActionGet(ref).getInteger(charIDToTypeID( 'ItmI' ));
              selectedLayers.push( srs);
         }
         return selectedLayers;
    }
    
    

    and if I put this:

         var ref = new ActionReference();
         ref.putEnumerated( charIDToTypeID('Dcmn'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
         ref.putProperty(charIDToTypeID('Prpr'), stringIDToTypeID('targetLayers'));
         var desc = executeActionGet(ref);
    
    

    I get the error saying that "-the"Get"command is not currently available."

    var ref = new ActionReference();
    ref.putEnumerated( charIDToTypeID('Dcmn'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
    ref.putProperty(charIDToTypeID('Prpr'), stringIDToTypeID('targetLayers'));
    var desc = executeActionGet(ref);
    

    I get the error saying that "-the"Get"command is not currently available."

    When you create a reference object, good command of containers is critical; It goes from the specific to the general. Think of it with 'of' inserted: get the target property layer of the current document.

    It should work then:

    var ref = new ActionReference();
    ref.putProperty(charIDToTypeID('Prpr'), stringIDToTypeID('targetLayers'));
    ref.putEnumerated( charIDToTypeID('Dcmn'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
    var desc = executeActionGet(ref);
