Event handling in Network UI element in Webdynpro

Hi ,
I am developing a hierarchial graph using Network UI element.I want to incorporate event handling so that the graph will respond to user actions like on double clicking a node an URL will be opened.I can notproceed with the event handling.
Can anyone tell me the procedure to do this from webdynpro java.
Regards
Nayeem

Hi Nayeem,
The Network UI element has lots of events defined for it which can be handled to get the desired functionality.
Go to the View in which you have added the Network Element, select the Element and go to the
properties tab.
Under events , you can see a list of events defined for this UI element.
Select the event you wish to handle and press the Create button which gets visible once
an event say onNodeSelected is selected
You can then give a name to the action say UserClicked and save it .
In the properties tab of the UI element , the action will be registed against the event .
Now select the event again and press the go button.
It will redirect you to the java editor of the view where in you can place your event handling logic.
Alternatively, if you have created the UI element dynamically then you can add the event to the UI element by using the following code
IWDNetwork network = (IWDNetwork)view.createElement(IWDNetwork.class);
network.setOnNodeSelected(/*Your Action handler already defined in the View*/);

Event handler elements inside of the array

I have an array of clusters, of which inside the cluster are buttons. I want to be able to tie an event handler to these buttons ( they would all handle the event the same, the only difference would be the index they were handling)
A while back a similiar problem was posted here:
http://forums.ni.com/t5/LabVIEW/Array-of-Clusters-with-Graph-Y-Scale-Change-Event/td-p/1194181/page/...
However, this solution did not appear to be able to deliver the index of which button in the array was pressed .. this is critical for my application. The button is basically an "edit' buttonw which allows the user to edit the elements of the cluster through a popup. Obviously I need to know which cluster the user intends to edit.

nathand wrote:
One option: when the code starts, build an array of references to the edit buttons inside each cluster. Then, in the event case, search that array for the reference that triggered the event. The index at which the reference is found tells you which cluster to edit.
This might work, but it should be possible for the user to add/delete elements from the array so I would need to be able to do this even after program initialization.
Currently, I have just made dozen buttons alongside the array of clusters. But this workaround won't allow past a fixed number at program initialization.

Javascript error in event handler! Event Type = element [edge.2.0.0.min.js:162]

I'm doing a little edge project (now in beta version) for my girlfriend (she hates the code), with examples of the animate() method and other functions like setInteval(), but when I run I get the following error in Chrome console:
Javascript error in event handler! Event Type = element [edge.2.0.0.min.js:162]
But this library is global for all projects, how is possible that trigger an error?
Example here:

Thanks.

you dont need to import java ease !!
it's already included in edge animate, remove that yepnope completely your problem will gone

Control not going from Adobe Interactive form to ABAP WD Event handler

Hi
I am facing an issue with adobe interactive forms and WD ABAP integration.
The buttons in adobe interactive form when clicked is going round and round and the control is not going to the ABAP code(WD ABAP event handler code whatsoever). I have also set the debugger but the control is not moving to the ABAP code from the adobe interactive form.
Can anyone help me what can be the issue here and how can I resolve the same?
Thanks.
Sid

Hi Babi,
In the adobe form layout library Use the Submit(which internally means submit to SAP) button from the Webdynpro Native category.
Only this button action can connect adobe to web dynpro.
Whenever we click on this particular button the event will be trigger in the ONsubmit event of interactive form UI element in the webdynpro.There we can write our abap code.Hope this will help you.

Display icons in Network ui element

Hello everybody!
Im trying to display some hierarchies in a Network ui element. Generally, this works fine, but I'm not able to display icons with the elements inside the applet. The examples in the JNet/JGantt Developer Documentation use <icon/>-tags with the path to a gif file in the Type Repository section like this
<type name="SomeTypeName" inherits="SomeBaseTypeName">
<icon space="5">apps/orgchart/chief.gif</icon>
</type>
and the Type Repository documentation tells me to
Specify the relative address of the URL in relation to the code base of JNet.jar
(a file in your own JAR. file: apps/slm/icon.gif, for example). If
the relative path starts with apps, JNet automatically adds the
missing com/sap/jnet. We recommend that you use the relative path
wherever possible, because you can store the icon graphics in the same directory
in Perforce as the type repository.
But how would I determine the relative address of my icon files stored in my web dynpros src/mimes/components/<component name>-folder inside my WebDynpro jar/ear/whatever in relation to the code base of the JNet.jar which - I guess - would reside inside the WebDynpro runtime or somewhere else on the server, but not inside my own jar ? Or am I wrong about this ?
Thanks a lot
Michael

Hi Christian!
That's what I tried in the first place. The result is something like
/usr/sap/XXX/J02/j2ee/cluster/apps/myCompany.com/my~webdynproapp/servlet_jsp/webdynpro/resources/myCompany.com/my~webdynproapp/root/Components/package.path.to.my.component/imagename.gif
but the applet does not find the image files. Since the JNet documentation says to specify the relative path from the JNet.jar code base, I'd have to find out where that is and calculate the relative path, but possibly this will only work inside a single jar (which I don't have since the JNet.jar is somewhere among the portal WebDynpro runtime components, I guess).
Preferrably, I'd like to have a look at a working example using the Network ui component with external icons inside a java WebDynpro. Propably someone has done that before...
Thanks

How to run a dialog's method from a button's event handler?

I've created my first dialog from the samples, but I am having trouble figuring out how to run a method in my dialog from an button's event handler. Can anyone please point me in the right direction?
function CreateDialog()
    this.windowRef = null;
CreateDialog.prototype.run = function()
    //...declare a bunch of vars
    // Create a window of type palette.
    var win = new Window("dialog", "Element Spray Generator",[iTop,iLeft,iTop + iWidth,iLeft + iHeight] ); // bounds = [left, top, right, bottom]
    this.windowRef = win;
    // Add a frame for the contents.
    win.btnPanel = win.add("panel", [iPadding,iPadding,iWidth-iPadding,iHeight-iPadding], "");
    .... add a bunch of other stuff ...
    win.btnAdd = win.btnPanel.add("button", [win.btnRemove.bounds.left - iPadding - iButtonWidth,win.lstImages.bounds.bottom + iSmPadding,win.btnRemove.bounds.left - iPadding,win.lstImages.bounds.bottom + iSmPadding +iTextHeight], "Add");
    win.btnAdd.onClick = function() {
       //todo implement this
       var f = File.openDialog("Open File") ;
       win.lstImages.add("item", f.displayName );
       this.EnableControls();    //<--- problem is on this line here!!
    this.EnableControls(); //<--- this works
    // Display the window
    win.show();
    return true;
CreateDialog.prototype.EnableControls = function (){
    var result = true;
    result = result && (this.windowRef.ddlPaths.selection != "");
    result = result && (this.windowRef.lstImages.items.length > 0);
    this.windowRef.btnOK.enabled = result;

This may not be the reason, but when using the way I create dialogs 'this' inside of an onClick points to the control.
    win.btnAdd.onClick = function() {
       //todo implement this
       var f = File.openDialog("Open File") ;
       win.lstImages.add("item", f.displayName );
       this.EnableControls();    //<--- I would expect it to call another function of btnAdd
                                        // this.parent.EnableControls() might be what you want if the control is not in some other container

Events for web dynpro UI elements

Hi,
In NWDS there are only a few event types associated with each UI element type. Say InputField has 'onEvent' event, DropDownList has 'onSelect' etc.
So, for the Input fields are we limited to triggering an event handler to fire only when the user hits the 'ENTER' key? What do I need to do to trigger an event handler for say when the user hits a 'TAB' key ? Is there some way we can extend the event listener interface to add more events to an UI element ?
Please advise. Thanks !
Sri

There is no event triggered when the input field looses focus.
You cannot add your own events.

BSP extension "download" - event handling problem

Folks,
First of all, I apologize if the answer is already out there, but I spent quite some time to find the solution for my problem but finally gave up:
I implemented the Download extension from Brian's and Tom's book. Since I am using an MVC based app, I put the event handling in the DO_HANDLE_EVENT of a controller instead of the OnInputProcessing event of a page. Here's how my app is designed:
I have a main controller that has an execute button to trigger a data selection based on some selection criteria. The result of this selection is displayed by means of a subcontroller with tableviews that are wrapped into my zdownload extension. Everything works fine: I make my selections, execute the app through the button of the main controller and get my result shown in the tableviews. I push the download icon, select my file format (XLS, HTML etc), get the dialog to choose whether to download or to display the file, perfect!
But now after I processed the download successfully - if I click the execute button in the main controller again, I still get the download dialog. It looks like the created event for the download does not get cleared. As I mentioned, I searched through SDN, but all I found were referrals to the call of DISPATCH_INPUT( ) in DO_REQUEST of the main controller, but unfortunately this one is already implemented.
Any ideas?
Thanks,
Guenther

There is an attribute of the download extension called display_url. You pass a value to the extension telling it what cached URL contains the binary content for your download. if this display_url attribute has a value assigned to it, then the element will render an iFrame to call the URl. However if the display_url attribute is empty, it won't render the iFrame. I suspect that you have a stateful application and after your download event you aren't clearing whatever field that you pass into the display_url attribute.

Event Handler Exception

Hi Friends,
I am trying to call a BAPI from a webdynpro application when a user
hits a button in a table. The table will have a button for each entry.
There is an iView that has the table, a custom controller that executes
the BAPI (model).
I am setting the value of the custom controller context at the onAction event handler of the iView and calling the method executeBAPI once the user hits the button. The problem is it works fine for the first time. If the user hits another button of the table on the same screen it throws a nullPointer exception. ie all the subsequent calls fail.
What could be wrong?

Event Handler is not being triggered- 11G Release2

Event handler doesn't work for a Canvas inside a canvas (Possible bug in Flex 4)

Hi Guys,
I have a canvas sitting inside another canvas. When i try to catch the mouseClick event in the child canvas, im not able to do it. When i change the child canvas component to a 'Panel', the event handler works perfectly fine. Any suggestions/solutions?

ok a few things you should know... it is recomended to use the spark components when working with flash builder 4 thought the mx components are available spark is much litghter in weight. also if you want to use the equivalent of a canvas in spark then you want to use a "group" but ill warn you they dont support inline styles, a border container looked more appropiate for what you were trying to do below. However. i did fix your code for flex 4.0

Event handler getting fired on all list and libraries

I have created an event handler and add it to a custom content type. Some how this event handler is getting fired on each every list which are there inside a site. Below is my content type declaration with fields and event handler. This content type
is being activated using a featur scope at "Site".
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">

You need to add the ListTemplateId or ListUrl to the Receiver element,
E.g. If you had a list definition with the template ID 10500, then your event receiver XML would look like this:
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<Receivers ListTemplateId="10500" >
<Receiver>
<Name>CIBDocumentHandlerItemAdding</Name>
<Type>ItemAdding</Type>
<Assembly>Common.SharePoint.Web, Version=1.0.0.0, Culture=neutral, PublicKeyToken=68d03adf96d84a47</Assembly>
<Class>Common.SharePoint.Web.Handlers.CIBDocumentHandler</Class>
<SequenceNumber>10500</SequenceNumber>
</Receiver>
</Receivers>
</Elements>
