How to get current viewed task

For an external synchronization requirement I need to maintain or be able to retrieve the current viewed task by a user. I'm hopeful that this has been solved before. Does anyone have any insight there? I'm considering setting up a table to maintain the current viewed taskid for the user, but even that is proving challenging with my lack of ADF exposure. I see the 'TaskSelectedEvent' in the wizard generated task form I'm using but I'm not sure how I might leverage that.
Any help is appreciated.

Yes. there is no API to get the current task.
Try this:
WDProtocolAdapter.getProtocolAdapter().getRequestObject().getParameter("wi_id");
But i still say a bit confused with your requirement.
The task id gets created only upon creation of a task. And you want this current task id in the BPM Process context? How is it possible unless and until some action takes place and the data is passed from WDJ to BPM Context?
Please clear my doubt.

How to get the view Object in UserDefined Action

Hi All,
Any body tell me how to get the view object , like the view object avilable in the wdDoModifyView() method as parameter.
I have requirement like, i want to change the , no of rows displaying in the table should be changed at the runtime based onthe no of rows selected in the dropdown box.
The action which i created will be assigned to that dropdown box, on select of the available option, i will get the view object and change the properties of the "maxrows" of the table .
so for getting the view object in the the Action methods tell me what is the procedure for getting the current view object.

Hello Vishal,
Simply create a value attribute (say rowCount) of type 'integer' and bind it to the 'visibleRowCount' property of your table. Then, in the actionHandler get the value from the UI element (in your case, I guess it is drop down) and set it to the attribute 'rowCount' like this.
wdContext.currentContextElement.setRowCount(
wdContext.current<nodeElement>.set<AttributeBound toDropDown>);

OK, we can play this game on and on...
I'll ask for a use case (http://en.wikipedia.org/wiki/Use_case) and you don't give any info we don't already know. After an other 10 posts we probably know what you real problem is and can give you the advice which you could have gotten in the fist place.
So please take some time and describe the problem as if you would ask your mother for help. Tell us how the data model is build and how the VO are related. Is there any input from an user involved? Which information from the other view do you need? How do you get to the doDML method? Is there a button in the ui involved?

how to get current rowindex ?
Thanks
Sanjiv Sharma

Only way I can think of is to use the rowset controller from the InProc RAS SDK. Here is a snippet of a sample code on how to:
//Load the report
if (clientDoc != null) {
//create metadata structure
RowsetMetaData rowSetMetaData = new RowsetMetaData(); rowSetMetaData.setDataFields
(clientDoc.getDataDefinition().getResultFields());
       Fields fields = rowSetMetaData.getDataFields();
       String colName,colTypeName;
       int colType, len;
       Field field;
       HashMap colNames = new HashMap();
       HashMap colTypes = new HashMap();
       for (int i = 0; i < fields.size(); i++) {
               field = (Field) fields.get(i);
               colName =field.getDisplayName(FieldDisplayNameType.description, Locale
.ENGLISH);
               colNames.put("COL"+i,colName);
       colType = getColTypeFromVariant(field.getType().toVariantTypeString());
       len=field.getLength();
              //Placeholder
        //add column metadata to data structure or XML
        Object colValue;
        int rowCount=0;
        if (getMaxRows() != 0) {
               RowsetCursor rowsetCursor = clientDoc.getRowsetController(). createCursor
(null, rowSetMetaData);
              //Setting the batch size to make sure that you get back all the
              //rows by setting the batch size.
                    clientDoc.getRowsetController().setRowsetBatchSize (rowsetCursor
.getRowset().getTotalRecordCount());
           //Getting the Results back starting from the first row
           RowsetCursor resultCursor = clientDoc.getRowsetController(). createCursor(null,
rowSetMetaData);
           resultCursor.moveTo(0);
              while (!resultCursor.isEOF()) {
                  for (int i = 0; i < fields.size(); i++) {
                           colName=(String)colNames.get("COL"+i);
                           colTypeName=(String)colTypes.get("COL"+i);
colValue=record.getValue(i);
                            //Placeholder
//add row data to data structure or XML
resultCursor.moveNext();

How to get current IUser (com.sapportals.portal.security.usermanagement)

Hi,
does anybody know how to get IUser for the current user?
I know how to get current IUser from com.sap.security.api package:
IWDClientUser wdcu = WDClientUser.getCurrentUser();
IUser sapUser = wdcu.getSAPUser();
but I need to have IUser from com.sapportals.portal.security.usermanagement package.
Regards,

Ladislav,
Try this:
Get the IUser uisng the API com.sap.security.api.IUser and store it in a variable, say <i>sapUser</i>.
Then,
// Convert the logged in user to old EP5 usermanagement API
com.sapportals.portal.security.usermanagement.IUser user = null;
try
com.sapportals.portal.security.usermanagement.IUser user = WPUMFactory.getUserFactory().getEP5User(sapUser);

How to get current assigned participant id?

Hi mates,
This might be a basic questions, but useful for me :)
How to get current assigned participant id from screenflow? Or How to pass it as an argument from interactive activity?
Below is what I tried.
Participant.id or Instance.participant.id - returns login user id
Thanks

Hi,
Please correct me if I understood wrong.
You want to know whether an instance is assigned or not and if assigned then you want to fetch the assigned participant id.
If this is your requirement then please find the code below and make the necessary changes into it.
Write the following code in screen flow automatic activity but before that you need to pass the instanceid as argument to the screen flow.
In the process as well as screen flow layer make an instance variable instanceid as Int.
Then make an argument variable instanceidArg as Int in both the screenflow and process layer and map accordingly so that it will take the instanceid from process layer to the screen flow layer.
Assign instanceid = id.number; in process layer automatic activity but before the global interactive activity where you have maped the screen flow.
Write the following code in screen flow automatic activity.
logMessage("============= instanceid ==============" + instanceid); //instanceid is the id of the instance that you have passed from process layer.
ProcessService ps;
InstanceFilter instF = InstanceFilter();
ps.connectTo(url : Fuego.Server.directoryURL, user : "<userid>", password : "<password>"); //In studio the userid and password will be same
logMessage("Connected");
instF.create(processService : ps);
instF.searchScope = SearchScope(participantScope : ParticipantScope.ALL, statusScope : StatusScope.ONLY_INPROCESS);
//<ProessId Name> is the id of the process where you want to know the assighed participant id
instF.addAttributeTo(variable : VarDefinition.processid, comparator : Comparison.CONTAINS, value : "/" + "<ProessId>");
instF.addAttributeTo(variable : VarDefinition.INSTANCE_NUMBER, comparator : Comparison.IS, value : Int(instanceid));
Fuego.Papi.Instance[] instances = getInstancesByFilter(ps, filter : instF);
foreach (instance in instances) {
logMessage("Assigned ?: " + instance.participantId.empty);
logMessage("instance.participantId: " + instance.participantId);
ps.disconnectFrom();

Urgent : How to get current user id

Hello,
fnd_global.user_id returns -1
fnd_profile.get('user_id',x_user_id) return null
can anyone help how to get current logged in user to apps.
Regards,
Dinesh.

Hi Dinesh,
You must also make sure you have initialised the app.
If you run this from sqlplus then it will return -1.
If however you run this from within a concurrent program then the user id will be returned.
Try using this from sqlplus fnd_global.apps_initialize
Eg.
begin
dbms_output.put_line(fnd_global.user_id);
fnd_global.apps_initialize(user_id => 3551,
resp_id => 1,
resp_appl_id => 1);
dbms_output.put_line(fnd_global.user_id);
end;

How to get current time and date??

How to get current time and date from my PC time and date to the java application??
i use java.util.* package but got error, that is:
- java.util.* and java.sql.* class are match
- abstract class cannot be instantiated
so what can i do, pls guide...thanks...

There is a method in the System class that will return the current system time. You could also instantiate a Date, Time, Timestamp, or Calendar object, all of which get created with the system time by default.
Don't import *. Import the specific classes you need.
Next time, post the actual text of the exceptions/compile errors. If you make people guess, most just won't bother.
