Catching onExpand and onCollapse events of treetableview
Hello,
I am using the bsp extension treeTableView of crm_bsp_library.
With this control it is possible to expand and collapse nodes.
In my controller I catch the onCollapse and onExpand events by the following code:
event = cl_htmlb_manager=>get_event_ex( request ).
tabview = ?= event.
case event->event_server_name.
when 'myExpand' or 'myCollapse'.
endcase.
this code is working so far. Now I would like to get to know in which row the myExpand or myCollapse node is fired.
event->rowselected contains the currently selected row (the one, which is red), but I cannot find any information on which row was expanded or collapsed.
Does anybody know where to get this information from?
Thanks for your help!!!

How to catch "Move" and "Copy" Events
I want certain functions to be called whenever a user moves an existing PageItem on a Page, or when he copied a PageItem onto a Page.

TIA,

How can i catch the gotfocus and lostfocus events
Hi Dear;
i tried to catch the gotfocus and lostfocus events, but i can't.
in the same code i can catch the onclick events.
is there any special code for the gotfocus and lostfocus events?
regards;Danny;
Whenever I have an issue such as this I fire up the event logger and it will show you exactly which events you can put your hooks into. If you are not using it you should really check it out. Will save you tons of time.

I know it's not the exact answer you were looking for but I hope it helps.

Cant add Rows In a Matrix (Child) and No event catching
Hi,
I created a Master File and its Child. Registered as an UDO. Created an UDO Form with the UDO Form Generator.
I Can Add, find, update, records to de Master File, but The Matrix related to the Child Table Only allows me enter information in the first Row.
I Have tried the addrow command in every place possible, but It doesnt work.
Dim oXmlDoc As Xml.XmlDocument
oXmlDoc = New Xml.XmlDocument
Dim sPath As String
sPath = IO.Directory.GetParent(Application.StartupPath).ToString
oXmlDoc.Load(sPath & "" & FileName)
SBO_Application.LoadBatchActions(oXmlDoc.InnerXml)
oForm = SBO_Application.Forms.Item("F_MX_C071")
The last thing I tried was include this next lines after
oItem = oForm.Items.Item("mtx_0")
oMatrix = oItem.Specific
oMatrix.AddRow(3)
I Also Cant catch the AddRow Event Button. I Set the filters and the event handling for menus and
oFilters = New SAPbouiCOM.EventFilters
oFilter = oFilters.Add(SAPbouiCOM.BoEventTypes.et_ITEM_PRESSED)
oFilter.AddEx("F_MX_C071")
SBO_Application.SetFilter(oFilters)
If (pVal.EventType = SAPbouiCOM.BoEventTypes.et_ITEM_PRESSED) Then
Events are catched before oForm = SBO_Application.Forms.Item("F_MX_C071"). After that, there´s no event catching
Can anyone help me? I have a lot of time spent in this issue.
Thanks a lot.I dont know if Is it clera for me now, but i try it.
You have matrix on user form. The matrix contains child data. This child data are inserted to matrix manualy or bounded to some datatable, i think with datatable?
When you add new line to matrix, Im using
omatrix.AddRow(1, 0) - 1 is that I want to add 1 row, 0 is position, where the new line will be in matrix
When the matrix is filled with code, Im doing it as
I update usertable
oUserTable.UserFields.Fields.Item("U_Popis").Value = ""
oUserTable.UserFields.Fields.Item("U_PATH").Value = ed.String
then update the form to affect changes to db
oOrderForm.Update()
and then I make new bounding to datatable.
Undestand I correctly it now? -
Using databases and container events?
I'm having trouble finding documents show how one should use databases and listen for container events? I'm using Berkley Java DB. I'll need all my remote object to have access to the database. How do I pass that in? Custom adapters? Also, when Tomcat shuts down I need to close the database, how would this be down? Custom adapters? So I may be answering my own question, but I'm asking cause I really don't see anything in the documentation that points this out. It really looks like I'd be using singletons and factories for this. I could register a Servlet or Servlet Context to listen for Tomcat events, but I figured it couldn't hurt to ask others using Blaze, as I'm very new to it. Thanks.
So how would you tell Blaze to use this? Is there something you put into the config file? My thoughts on all this is to use PicoContainer to manage all services then create an adapter to inject all resources when creating remote objects. But this seems a little heavy if Blaze can do all this for me. The adapter seems like the injection point to me. Is that not what it's used for? Or is using it like that bad practice under Blaze? I've read all I can find on Blaze, so either it's missing docs, or I'm not finding them all. If I'm missing them, by all means let me know where to go. I don't want to ask questions that are already answered in documents else where.

Using databases and container events?
I think it's mainly in JavaDocs but here's a sample I have where I check to make sure the HSQLDB is running as the BlazeDS starts up:
import java.sql.Connection;
import java.sql.SQLException;
import flex.messaging.config.ConfigMap;
import flex.messaging.services.AbstractBootstrapService;
public class DatabaseCheckService extends AbstractBootstrapService
// This is called right before server starts up.
public void initialize(String id, ConfigMap properties)
Connection c = null;
try
// Check that the database is running...
c = ConnectionHelper.getConnection();
// ... if yes return
return;
catch (SQLException e)
System.out.println("DB is not running!");
finally
ConnectionHelper.close(c);
// This is called as server is starting.
public void start()
// No-op
// This is called as server is stopping.
public void stop()
// No-op

ADF Drag and drop event inside the single af:treetable
Hi Experts,
I have a af:treeTable in my ADF web project and i would like to implement the drag and drop event to the same tree table for supporting my sample test project use case. Currently i am facing some issue to get the source tree node and the destination tree node of the drop and drop event inside my drop listener method. How can i get those object since i need to perform some business operation inside the listener. Please note that i am not using ADF BC4j in my project. The service layer is implemented as EJB and it's being called from the backing bean.
Looking forward some guide lines to resolve this issue from you experts.
Thank you.It's not a perfect solution, but a work in progress that i'm currently using in my backing bean:
private RichTree navTree;
private void exitContainers() {
boolean success = false;
while (!success) {
try {
navTree.exitContainer();
} catch (Exception e) {
success = true;
private void clearDisclosedRowKeys() {
if (navTree != null && navTree.getDisclosedRowKeys() != null) {
RowKeySet rks = navTree.getDisclosedRowKeys();
Iterator rksIter = rks.iterator();
while (rksIter.hasNext()) {
exitContainers();
List<Integer> rowkey = (List<Integer>) rksIter.next();
List<Integer> newRowkey = new ArrayList<Integer>();
for (Integer row : rowkey) {
if (navTree.isRowAvailable(row)) {
navTree.setRowIndex(row);
navTree.enterContainer();
newRowkey.add(row);
} else {
// Row is no longer available
break;
if (newRowkey.size() == 0) {
rks.remove(rowkey);
} else {
rowkey.clear();
rowkey.addAll(newRowkey);
Whenever you make a 'delete' or 'move' in the tree, call clearDisclosedRowKeys(), it will remove anything that's no longer valid, so your tree won't collapse, and you won't get the error anymore.
I took out my logging and debug statements, but essentially this just gets all the rows, checks to see if they're valid, and if so creates a new RowKeySet with the valid rows in it.
Of course make sure you have the setNavTree and getNavTree accessor's created and that they're bound in your JSFF, otherwise navTree will always be null.
I haven't yet found a way to 'nicely' find out if you're at the top level container, so i'm relying on an Exception to occur to give me that information, if anyone knows a better solution please feel free to share it. -
Catching the browser close event...
Hello Fellow Portal-Heads,
There's a nagging issue that I've been pondering (RE EP6 NW04). In the MSS iViews there is the potential issue of a user viewing an employee and then closing the browser via the 'X' (vs. clicking the logoff link). This 'X-ing' out of the browser leaves the viewed employee locked which is to be expected. So... anyone have a good way to catch the 'X-ing' out of the browser and then trigger some code to perform a proper logoff? I've tried inserting code in the masthead which catches a browser unonload() event... but it was not the smoothest operator.
Cheers,
Mike

I have got a chance to work in a similar issue.The following code traps the 'X' of the browser and logoff the user.
<script type="text/javascript">
window.onunload = function unloadEvent()
if (gIsPreviewMode)
return;
else
if(window.screenLeft < 10004)
//this is refresh
else
logoff();
</script>
Preview is taken care and the code is working fine. I am posting code so that somebody else can use it,
Regards

Because of the Change/Changing changes in VideoPlayer, we need to also listen for a CHANGE as well as the CHANGE_END, CHANGE_START, THUMB_PRESS, and THUMB_RELEASE events.
Also, when clicking on the track and animating, the scrubbar's playedArea should move along with the thumb. We do this by using pendingValue, rather than value in updateSkinDisplayList().

Bugs: SDK-24528
Reviewer: Kevin
Tests run: checkintests
Is noteworthy for integration: No
Ticket Links:
http://bugs.adobe.com/jira/browse/SDK-24528
Modified Paths:
flex/sdk/trunk/frameworks/projects/spark/src/spark/components/VideoPlayer.as
flex/sdk/trunk/frameworks/projects/spark/src/spark/components/mediaClasses/ScrubBar.asMy first observation is that you don't reraise the error in the CATCH handler. That is bad, because it makes the proceedure fail silently which may be very difficult to troubleshoot.
The version numbers for Change Tracking are indeed database-global. MIN_VALID_VERSION can be different for different tables, if they have different retention periods. But if they all have the same retention period, it seems likely that MIN_VALID_VERSION
would increase as the database moves on.
I'm not sure about your question Can we use the CHANGE_TRACKING_CURRENT_VERSION even though we want to download subset of data from the table (only records matching for one data_source_key at a time). Where would you use it? How would you use
it?

How to catch IE7 tab change event in Java Applet?
My applet have some modeless dialogs, When I start my applet with modeless dialog in tab1, if I swith to tab2, the modeless dialog of tab1 remains open.
So I want to catch the tab change event, and set modeless dialog invisible when tab changes.
Who knows the solutions.... ThanksTo get to the IE7 browser, you'll have to go through JNI if you're using Java to get to a C level interface. You'll have to write the code to interface to it also. IE7 does not have a Java interface, inface, MS has a vested interest in not supporting a Java interface. You'll have to look up the IE7 developers docs to see the OLE interface you'll have to hit.

Catching the Record Change Event
Hello,
We are currently using SAP 2004, and would like to catch an event when a sap record changes, for example in Item Master Data window when the user clicks on the << < > >> and the Item Number/ Information changes. From what I can tell there is no specific form event that can be caught like on item number text change
Any help with this problem would be greatly appreciated
ThanksHi Bill,
Unfortunately, there is not a "record change".
You'll have to catch all the menu event when the user click on the << < > >>
Private Sub SBO_Application_MenuEvent(pVal As SAPbouiCOM.IMenuEvent, BubbleEvent As Boolean)
If pVal.BeforeAction = False Then
Select Case pVal.MenuUID
Case "1288" 'Next Record
oRecordSet.MoveNext
'// If reached EOF show last
If oRecordSet.EOF = True Then
oRecordSet.MoveLast
End If
Case "1289" 'Previous record
Case "1290" 'First record
Case "1291" 'Last record
End Select
End If
End Sub -
Catch logout or shutdown event
Hi all,
is there a way to catch a Windows log off or/and shutdown event in LV? For me it's totally anoying that with a running DSC Engine a first log off/shutdown does only stop the DSC Engine and then forgets about it. Further on I have a second "background" process running that looks at the DSC Engine. As it doesn't know about the shutdown/log off it's just registering the DSC Engine stop (that's fine so far), but needs an additional log off event to be stopped.
I found a promising thread http://forums.ni.com/ni/board/message?board.id=170&message.id=89988 identifying the problem. What I would like to do now, is catching the WM_QUERYENDSESSION message of windows using the nevertheless running backgroud process of mine, wait for the shutdown of the DSC Engine (or shutting down it explicitely) and then call the shutdown/log off again (that means I'll have to know whether a shutdown or a log off was requested). But that will soon be annyoing, if there are some more LabVIEW apps running.
Better would be a bug fix by NI which doesn't kill the WM_QUERYENDSESSION...
So far,
CarstenHi Kai,
actually I'm not closing the VI at all. It's running all the time as well as the DSC engine.
The problem is not really, that the DSC engine and the VI don't close, *but* that they seam to tell Windows "hey - we don't want to quit" by setting WM_QUERYENDSESSION to 0 (as the thread mentioned above states). By that Windows simply "forgets" to procede with the shutdown or log off. The funny thing is, that almost anytime the DSC Engine seems to be the first of my two problematic LabVIEW programs getting the WM_QUERYENDSESSION message.
So I don't want to shutdown Windows directly from my VI at all. It's just a "dirty" hack I hope to accomplish:
* catch WM_QUERYENDSESSION
* shutdown the DSC Engine deliberately to be sure
* call a shutdown program wich will wait some seconds in the background
* exit my program
So the problem is how I got knowledge of the requested shutdown and how I can distinguish beetween log off and shutdown (poweroff, restart). Maybe I'll have to write a small C program and communicate with my LabVIEW program :-(... Maybe it's a task to do in LabWindows/CVI?
