Get element UI property in Event Handler
Hi,
it's possible read inside an action, ONACTIONGO_TO_DETAIL, the property TEXT, of a LinkToAction?
I want to read the property : TEXT of the LinkToAction and use this property like a parameter of the navigation :
WD_THIS->FIRE_TO_DETAIL_PLG( LV_TEXT ).
I have tried in some way, but i have obtained always error of Access Null. For example :
data: lr_linkToaction type ref to IF_WD_VIEW_ELEMENT, "CL_WD_LINK_TO_ACTION,
myView type ref to if_wd_view,
LV_TEXT type WDY_MD_TRANSLATABLE_TEXT.
CALL METHOD MYVIEW->GET_ELEMENT
EXPORTING
ID = 'LTA_COMPCODE'
RECEIVING
ELEMENT = lr_linkToaction
OR :
lr_linkToAction ?= myView->get_element( 'LTA_COMPCODE' ).
CALL METHOD LR_LINKTOACTION->GET_TEXT
EXPORTING
AS_EXTERNAL =
CONTEXT_ELEMENT =
CONTEXT_NODE_PATH_NAME =
TEXT_LENGTH = CO_UNKNOWN_TEXTLEN
RECEIVING
VALUE = LV_TEXT.
Hi Antonello,
You cannot get a refernce to if_wd_view simply by declaring a variable referencing it. You can get a reference to it only through the WDDOMODIFYVIEW method.
What you can do is, bind the 'text' property of your button to an attribute in the context and then simply read that attribute (the caode can be generated using code wizard).

Getting task id in boundary event handler
Oracle BPM 11.1.1.6
I have a human task in my process and I want to send out some very customized notification ( very different to the original assignment notification) to the assignee if the task is not actioned within a certain duration. For this I am having a non interrupting boundary event handler attached to the task which connects to a notification activity. The notification content needs to include an URL , which has the task id as part of it. ( we are using a custom worklist app ). Question: is there a way to get the taskid of the task for including it in the content of notification activity ?
TIA,
AtheekHi
UBR and UER are amounts that system calculate for the entire draft invoice and the entire draft revenue.
Since usually invoice and revenue are generated at the project level, the task id is not a valid parameter for AA, since there could be multiple tasks on the same document.
If in your case you are sure the revenue and invoice document always contains a single task, you could try a workaround using AA rule based on SQL statement. The logic will be to select any bill item within the invoice or revenue (either EI RDL or an Event) and read the task id of that item.

Event handler for dropdownlistbox how to determine selection ?
Hello,
As a newby in BSP programming, I'm trying to build a small application with a menu structure . This menu is defined in a page fragment and consists of dropdownlistboxes. The event handling is located in the main page which contains the page fragment.
My problem is that I cannot get these dropdownlist boxes to work. The coding in the page fragment is :
==========================
<htmlb:content>
<htmlb:form>
<htmlb:dropdownListBox id = "myDropdownListBox1"
tooltip = "Tooltip for my DropdownListBox"
onClientSelect = "alert('myDropdownListBox1')"
onSelect = "mySelect" >
<htmlb:listBoxItem key = "k1"
value = "MenuChoice1" />
<htmlb:listBoxItem key = "k2"
value = "MenuChoice2" />
<htmlb:listBoxItem key = "k3"
value = "MenuChoice3" />
<htmlb:listBoxItem key = "k4"
value = "MenuChoice4" />
<htmlb:listBoxItem key = "k5"
value = "MenuChoice5" />
<htmlb:listBoxItem key = "k6"
value = "MenuChoice6" />
</htmlb:dropdownListBox>
</htmlb:form>
</htmlb:content>
==========================
The event handler ( OnInputProcessing ) code is :
==========================
CLASS CL_HTMLB_MANAGER DEFINITION LOAD.
DATA: event TYPE REF TO if_htmlb_data,
ddlb_event TYPE REF TO CL_HTMLB_EVENT_SELECTION.
event = CL_HTMLB_MANAGER=>get_event( runtime->server->request ).
IF event IS NOT INITIAL AND event->event_name =
'dropdownListBox'.
ddlb_event ?= event.
CASE event->event_id.
WHEN 'myDropdownListBox1'.
CASE ddlb_event->selection.
WHEN 'k1'.
.......( Contains other statements )
WHEN 'k2'.
.......( Contains other statements )
WHEN 'k3'.
.......( Contains other statements )
WHEN 'k4'.
.......( Contains other statements )
WHEN 'k5'.
.......( Contains other statements )
WHEN 'k6'.
.......( Contains other statements )
ENDCASE.
ENDCASE.
ENDIF.
==========================
I have tried several different event handlers including the example in the documentation of the dropdownlistbox HTMLB element, but in the event handler I don't know how to determine the selection made.
I would appreciate it hugely if someone could give me an example how to do this ?
With regards,
Fred van de LangenbergHello,
Thanks for your answers & suggestions Subramanian, Ulli & Sebastian.
I forgot the <htmlb:content> tags ( thanks Ulli ) and eventually I got things working with the following :
Main page layout : dopdownlistbox element
<htmlb:dropdownListBox
id = "Ddlb1"
onSelect = "OnInputProcessing" >
selection = "<%= selection1 %>"
<htmlb:listBoxItem key = " "
value = " "/>
<htmlb:listBoxItem key = "k1"
value = "k1" />
<htmlb:listBoxItem key = "k2"
value = "k2" />
<htmlb:listBoxItem key = "k3"
value = "k3" />
<htmlb:listBoxItem key = "k4"
value = "k4" />
<htmlb:listBoxItem key = "k5"
value = "k5" />
</htmlb:dropdownListBox>

Event handling from class to another
i get toolbarDemo.java which make event handling to JTextArea in the same class
http://java.sun.com/docs/books/tutorial/uiswing/components/example-1dot4/index.html#ToolBarDemo
but i have another class and i make object of toolBar class and i move toolBar icons only how can i move the event handling as open ,save,copy,paste to my another class
i want to ignore actionPerformed of toolBar class and listen to my another's class actionPerformed
thanksRather than trying to use the ToolBarDemo class as-is you can use/modify the methods in it for your own class, like this:

I have configured SAP event managment based on configuration guide. I am new to SAP EM.
Can you let me know the followings-:
1) Is Event handler needs to be activated. If so how?
2) I am not getting any data when executing Event handler list in transaction /SAPTRX/EH_LIST.

I am trying to build a proof of concept where a WPF form is hosted in a seperate runspace and updates are handled from the primary shell/runspace. I have had some success thanks to a great article by Boe Prox, but I am having an issue I wanted to open up
to see if anyone had a suggestion.
My goals are as follows:
1.) Set control properties from the primary runspace (Completed)
2.) Get control properties from the primary runspace (Completed)
3.) Respond to WPF form events in the UI runspace from the primary runspace (Kind of broken).
I have the ability to read/write values to the form, but I am having difficulty with events. Specifically, I can fire and handle events, but the minute I try to reference the $SyncHash from within the event it appears to cause a blocking condition hanging both
runspaces. As a result, I am unable to update the form based on an event being fired by a control.
In the example below, the form is loaded and the following steps occur:
1.) Update-Combobox is called and it populates the combobox with a list of service names and selects the first item.
2.) update-textbox is called and sets the Text property of the textbox.
3.) The Text value of the textbox is read by the function read-textbox and output using write-host.
4.) An event handle is registered for the SelectionChanged event for the combobox to call the update-textbox function used earlier.
5.) If you change the selection on the combobox, the shell and UI hangs as soon as $SyncHash is referenced. I suspect this is causing some sort of blocking condition from multiple threads trying to access the synchronized nature of the hash table, but I am
unsure as to why / how to work around it. If you comment out the line "$SyncHash.TXT_Output.Dispatcher.Invoke("Send",[action]{$SyncHash.TXT_Output.Text = $Value})" within update-textbox the event handler will execute/complete.

This may not be possible, but I thought I would throw it out there. I appreciate your help in looking into this.
To clarify the "Respond to control events in the main runspace"... I'm would like to have an event generated by a form object in the UI runspace (ex: combo box selectionchanged event) trigger a delegate within the main runspace and have that delegate in
the main runspace update the form in the UI runspace.
ex:
1.) User changes selection on combo box generating form event
2.) Event calls delegate (which I have gotten to work)
3.) Delegate does some basic processing (works)
4.) Delegate attempts to update form in UI runspace (hangs)
As to the delegates / which runspace they are running in. I see the $synchash variable if I run get-var within a delegate, but I do not see the $Form variable so I am assuming that they are in the main runspace. Do you agree with that assumption? -
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
NayeemHi 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*/);

Using yepnope, getting error in event handler.
Recently discover yepnope and started to implement it into my project to keep common functions in one file. The first set of functions worked fine when I moved them over, but with the last one I'm unable to control a symbol. It's calling the function fine, it's just wont play the symbol timeline.
-------Here's the function in the external file
//Function for audio button
// Tests the paused attribute and set state.
voButton = function (){
if ($('#voiceOver')[0].paused) {
console.log("play");
$('#voiceOver')[0].play();
sym.getComposition().getStage().getSymbol("btnSound").stop(1000);
else {
console.log("pause");
$('#voiceOver')[0].pause();
sym.getComposition().getStage().getSymbol("btnSound").stop(0);
-------Here's the call to the function
Symbol.bindElementAction(compId, symbolName, "${_btnSound}", "click", function(sym, e) {
voButton();
//Edge binding end
Calling the function plays the audio but doesn't change the symbol. Getting the error message:
functions.js (line 39)
Javascript error in event handler! Event Type = element
I've tried different combinations of getComposition() or getSymbol(), nothing. I read a post somewhere that said I needed to prefix my function creation with sym. and call it the same way. This didn't work either and caused the function to stop working, but with a new error: sym is not defined in the external file.
Like I said the function works when I call it, but I can't access the symbol's timeline for some reason.I'm trying to include a custom js file to an Edge project, and I'm getting the same "sym is not defined" error. have you found a workaround for this problem?
can't we just use "sym" or methods like "getSymbol()" in the js loaded by yepnope?
I can't find any sources about this.
And I can't find an easy way to substitute "sym"...
Thanks in advance -
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

Unable to get automatic event handling for OK button.
Hello,
I have created a form using creatobject. This form contains an edit control and Search, Cancel buttons. I have set the Search buttons UID to "1" so it can handle the Enter key hit event. Instead its caption changes to Update when i start typing in the edit control and it does not respond to the Enter key hit. Cancel happens when Esc is hit.
My code looks like this -
Dim oCreationParams As SAPbouiCOM.FormCreationParams
oCreationParams = SBO_Application.CreateObject(SAPbouiCOM.BoCreatableObjectType.cot_FormCreationParams)
oCreationParams.UniqueID = "MySearchForm"
oCreationParams.BorderStyle = SAPbouiCOM.BoFormBorderStyle.fbs_Sizable

oForm.Visible = True
'// set the form properties
oForm.Title = "Search Form"
oForm.Left = 300
oForm.ClientWidth = 500
oForm.Top = 100
oForm.ClientHeight = 240
'// Adding Items to the form
'// and setting their properties
'// Adding an Ok button
'// We get automatic event handling for
'// the Ok and Cancel Buttons by setting
'// their UIDs to 1 and 2 respectively
oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
oItem.Left = 5
oItem.Width = 65
oItem.Top = oForm.ClientHeight - 30
oItem.Height = 19
oButton = oItem.Specific
oButton.Caption = "Search"
'// Adding a Cancel button

oItem.Left = 75
oItem.Width = 65

oItem.Height = 19
oButton = oItem.Specific
oButton.Caption = "Cancel"
oItem = oForm.Items.Add("NUM", SAPbouiCOM.BoFormItemTypes.it_EDIT)
oItem.Left = 105
oItem.Width = 140
oItem.Top = 20
oItem.Height = 16
Dim oEditText As SAPbouiCOM.EditText = oItem.Specific
What changes do i have to make to get the enter key to work?
Thanks for your help.

SheetalHello Felipe,
Thanks for pointing me to the correct direction.
So on refering to the documentation i tried out a few things. But I am still missing something here.
I made the following changes to my code -
oForm.AutoManaged = True
oForm.SupportedModes = 1 ' afm_Ok
oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
oItem.Left = 5
oItem.Width = 65
oItem.Top = oForm.ClientHeight - 30
oItem.Height = 19
oItem.SetAutoManagedAttribute(SAPbouiCOM.BoAutoManagedAttr.ama_Visible, 1, SAPbouiCOM.BoModeVisualBehavior.mvb_Default)
oButton = oItem.Specific
oButton.Caption = "OK"
AND
oForm.Mode = SAPbouiCOM.BoFormMode.fm_OK_MODE
oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
oItem.Left = 5
oItem.Width = 65
oItem.Top = oForm.ClientHeight - 30
oItem.Height = 19
oItem.AffectsFormMode = False
I get the same behaviour OK button changes to update and enter key does not work.
Could you please tell me find what is it that i am doing wrong?

Input value given on web page is not getting pickedup in event handler
Hi friends,
I have created one simple page in SE80 with program with flow logic option, in which I would like to show business partner details from BUT000 table with the input of partner number. But the thing is the input value(partner no.)which I am giving on web page is not getting picked up in selection in event handler though I am giving input value it is becoming initial while selecting. What could be the reason?
Below I am mentioning the code which I have written in even handler for OnInputProcessing event.
CASE EVENT_ID.
WHEN 'select'.
NAVIGATION->SET_PARAMETER( 'partner' ).
SELECT * FROM but000 INTO TABLE I_but000 WHERE partner BETWEEN partner AND partner1.
WHEN OTHERS.

Swing: when trying to get the values from a JTable inside an event handler
Hi,
I am trying to write a graphical interface to compute the Gauss Elimination procedure for solving linear systems. The class for computing the output of a linear system already works fine on console mode, but I am fighting a little bit to make it work with Swing.
I put two buttons (plus labels) and a JTextField . The buttons have the following role:
One of them gets the value from the JTextField and it will be used to the system dimension. The other should compute the solution. I also added a JTable so that the user can type the values in the screen.
So whenever the user hits the button Dimensiona the program should retrieve the values from the table cells and pass them to a 2D Array. However, the program throws a NullPointerException when I try to
do it. I have put the code for copying this Matrix inside a method and I call it from the inner class event handler.
I would thank you very much for the help.

here goes the code:

public class MathF2 extends JFrame {

Calcular.setEnabled(false);
Ativar = new JButton("Dimensionar");
label1 = new JLabel("Clique no bot�o para resolver o sistema.");
label2 = new JLabel("Qual a ordem do sistema?");
DimOfSis = new JTextField(4);
DimOfSis.setText("0");
JTable DataTable = new JTable(10,10);
container.add(label2);

for (int j = 0 ; j < n ; j++ ){
Object temp1 = model.getValueAt(i,j);
String temp2 = String.valueOf(temp1);
A[i][j] = Double.parseDouble(temp2);What I did is set up a :
// This code will setup a listener for the table to handle a selection
players.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
ListSelectionModel rowSM = players.getSelectionModel();
rowSM.addListSelectionListener(new Delete_Player_row_Selection(this));
//Class will take the event and call a method inside the Delete_Player object.
class Delete_Player_row_Selection
implements javax.swing.event.ListSelectionListener
Delete_Player adaptee;
Delete_Player_row_Selection (Delete_Player temp)
adaptee = temp;
public void valueChanged (ListSelectionEvent listSelectionEvent)
adaptee.row_Selection(listSelectionEvent);
in the row_Selection function
if(ex.getValueIsAdjusting()) //To remove double selection
return;
ListSelectionModel lsm = (ListSelectionModel) ex.getSource();
if(lsm.isSelectionEmpty())
System.out.println("EMtpy");
else
int selected_row = lsm.getMinSelectionIndex();
ResultSetTableModel model = (ResultSetTableModel) players.getModel();
String name = (String) model.getValueAt(selected_row, 1);
Integer id = (Integer) model.getValueAt(selected_row, 3);
This is how I got info out of a table when the user selected it -
How to get contents of a shuttle in event handler
Hi,
I'm trying to get the contents of the two list of a <shuttle> element.
The documentation of <shuttle> says, it can be accessed, after the form is committed, through "-shuttleName-:Leading:items". But when I try to get the contents in the event triggered by a submit button, there seems to be no content at all.
Any hints welcome,
Best regards,
SvenHi,
there is an error in the documentation of the shuttle tag. It should be "-shuttleName-:leading:items".
Then it works, except for some strange behavior:
- From an empty list no values can be retrieved.
- When filling a list with fixed options the values of the options are retrieved as expected.
- When using a bc4j:optionList inside the leading or trailing list of the shuttle an no items are moved before the form is submitted the only thing that can be retrieved from the list is ";".
- If some items are moved before submitting the values of the remaining options can be retrieved as normal.
Is this a bug?
I also checked the generated html-code. The "bug" starts there. When using fixed options, something like <input type="hidden" value="1;2;3;" name="myShuttle:leading:items"> is generated. When using a bc4j:optionList ther is only a ";" for value.
Greetings,
Sven -
How to get a form field valud in delete PL/SQL Button Event Handler
Hi Friend,
I have a form. when user clicks delete button. we want to remove system dodelete function
and add a delete script
Under delete-top category,
how can I get value of form EVENT_NUMBER field in form at delete PL/SQL Button Event Handler?
DELETE FROM PTEAPP.PTE_EVENTS WHERE eventnumber = EVENT_number
But when I try to save this form and get message as
1721/15 PLS-00201: identifier 'EVENT_NUMBER' must be declared
Thanks for any help!
newuserI did something similar but wasn't using a stored procedure. Couldn't you set a flag variable once you know you're not doing the insert and in the "before displaying the form" section put an IF to check if your flag was set, and if so do an HTP.Print('You are overpaid buddy!');
Then just reset your flag.
