How to extend a user session time programmatically?

Emmanuel — Fri, 31 Mar 2017 10:47:49 -0400

Dear Ivy support,

Using Ivy 6.2 we set the User session time-out value in the web.xml. Is there a way to extend the session validity programmatically without any User action?

In a JSF context, would this method have any effect on the Ivy Session ? javax.faces.context.ExternalContext.setSessionMaxInactiveInterval(int interval) Specifies the time, in seconds, between client requests before the servlet container will invalidate this session.

Thanks in advance Emmanuel

Assign and revoke Role to Session User dynamically

Emmanuel — Thu, 31 Mar 2016 10:26:20 -0400

Hello,

I need to assign and revoke Ivy Role dynamically on the session user. If I understand the API documentation well, the following method assigns the given role to the session, the role should be automatically unassigned after logout: Ivy.session().assignRole(role);

Here the API documentation:

@PublicAPI(value=EXPERT) Assigns a role to the session. Parameters:role The role to assign

The problem is that I need also to revoke an Ivy Role dynamically, I could not find a method like Ivy.session().revokeRole(IRole role) or Ivy.session().unassignRole(Irole role). Is there a possibility to do that?

Thanks a lot in advance.

TaskQuery case insensitive search

Emmanuel — Fri, 14 Aug 2015 16:36:27 -0400

Hi all,

Is it possible to search against String Task properties with a TaskQuery so that the search is performed case insensitive.


    TaskQuery stringFieldQuery = TaskQuery.create();
    stringFieldQuery.where().name().isLike("my task name");

I would like that such a query returns the tasks which name is "MY Task NAme". Thanks in advance

How to dynamically start a task from a process that was started from an HTML Dialog

Emmanuel — Thu, 25 Jun 2015 23:25:10 -0400

Hi all,

In a JSF Dialog we can start a task dynamically with:

FacesContext.getCurrentInstance().getExternalContext().redirect(ivy.html.taskstartref(ivy.wf.findTask(95)));

We can also start an IProcess dynamically with something like that:

IRequest request = requestFactory.createRequest(processStart, thisMapOrEmptyMapIfNull(params)); 
IResponse response = responseFactory.createResponse(); 
IRequestHandler requestHandler = (IRequestHandler)processStart.getProcessModelVersion().getAdapter(IProcessEngine.class); 
requestHandler.handleRequest(request, response);

Now we would like to combine both to start a process dynamically that should in turn start a task. The process can be started from within the JSF Dialog.
In the started process, as we are not in the JSF context, the following does not work (fails silently):

FacesContext.getCurrentInstance().getExternalContext().redirect(ivy.html.taskstartref(ivy.wf.findTask(95)));

The following code does not work as well (fails silently):

IHttpResponse resp = ivy.response as IHttpResponse;
resp.sendRedirect(ivy.html.taskstartref(in.task));

We tried also:

IHttpResponse resp = ivy.response as IHttpResponse;
HttpServletResponse sresp = resp.getHttpServletResponse();
sresp.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY);
sresp.setHeader("Location",ivy.html.taskstartref(in.task));
sresp.sendRedirect(ivy.html.taskstartref(in.task));
sresp.flushBuffer();

Here we get:
IllegalStateException: Cannot change buffer size after data has been written
Cannot set content type. Response already committed

Is there a possibility to achieve what we try to do? Like for the process-start I have tried to find a proper IRequestHandler for starting a task. I have not found it.

Thanks a lot in advance

Detect a user session is closing because of timeout

Emmanuel — Sat, 13 Jun 2015 10:22:25 -0400

Hi everybody,

Is there a way to detect a user session is closing because of a timeout? There is the "unload" event that can be catched in an ULC Rich Dialog for performing some stuff when the user close a Dialog. Is there something similar for a session timeout?

If not it would be very usefull to have such a possibility.

Thanks in advance Emmanuel

TaskQuery for description search

Emmanuel — Tue, 09 Jun 2015 11:50:46 -0400

Hi all,

Is that possible to make a search for tasks by their description? A search by name is possible through:

TaskQuery stringFieldQuery = TaskQuery.create();
stringFieldQuery.where().name().isLike("search by name");

I guessed it was the same for the description but it seems to be unpossible to do such a TaskQuery for the description because the following code returns an IColumnFilterQuery and not an IStringColumnFilterQuery as for the name():

stringFieldQuery.where().description() // There is no isLike("...") method then.

Is there another possibility with the TaskQuery?

Thanks in advance

TaskQuery isInvolved and canWorkOn

Emmanuel — Fri, 29 May 2015 15:25:40 -0400

Hello,

What does mean isInvolved for a SecurityMember in a TaskQuery? If I want to get all the tasks that I can start, is "canWorkOn" enough?

Thanks a lot in advance!

Example:

ISecurityMember member = Ivy.wf().getSecurityContext().findUser(username);

TaskQuery taskUserQuery = TaskQuery.create();
taskUserQuery.where().isInvolved(member);
taskUserQuery.where().or().canWorkOn(member);

Is it possible to find the ICase that has lead to another ICase creation?

Emmanuel — Wed, 11 Mar 2015 02:54:29 -0400

Hi everybody!

I have a process which triggers another process start through a trigger step. The first process has a related ICase (ivy.case) and the 2d started process belongs to another ICase. We could consider in such a situation that the first ICase is the "ancestor" of the second one. Is there a possibility to get a reference to the "ancestor" ICase from the second one? Especially in a WorkflowEvent Listener like the one stated in this question: listen-to-process-case-start-and-task-creation-start

A very convenient way would be something like:

IWorkflowEvent createEvent = wfManager.findWorkflowEvent(event.getId());
if (createEvent.getEventKind() != WorkflowEventKind.EVENT_CREATE_CASE) {
return;
}
ICase newCase = createEvent.getCase();
newCase.getAncestorICase() // null if no ancestor, the ICase from which this newCase has been triggered

Thanks a lot in advance! Cheers Emmanuel

Listen to process-case start and task creation & start

Emmanuel — Tue, 03 Mar 2015 17:07:50 -0500

I would like to know if there is a possibility to dynamically listen to all ivy standard processes starts and ivy task creations and starts. The idea would be to get a reference to any standard processes-cases that are started or tasks that are created.

Thanks a lot in advance

How can I find out if a user is logged in?

Emmanuel — Thu, 08 Mar 2012 08:40:26 -0500

I need to know if a particular user has an active session in an Ivy application, or in other words whether he is currently loggedin.

I can get a particular IUser with Ivy.session.getWorkflowContext().getSecurityContext().findUser("username") and I can get all the sessions with ivy.session.getWorkflowContext().getSecurityContext().getSessions().

But I cannot find the way to see if the user is part of one of these sessions?

RListDisplay Scrollbar

Emmanuel — Thu, 06 Jan 2011 07:46:58 -0500

I use the RListDisplay Widget in Ivy 4.1.2 and 4.1.3 to display other components dynamically and it works good so far.

The RListDisplay shows a vertical Scrollbar as soon as there is not enough vertical place to show all the components. It is included into a Rich Dialog and the list of components to load in the RListDisplay is built in the Rich Dialog Start method.

The problem is that the scrollbar scrolls automatically to the end of the ListDisplay after the RDC has been loaded. I can not get the scrollbar to stay "quiet" at the 0.0 position.

I have tried with the "ListDisplay.setAutoscrolls(false);" method or with panel.ListDisplay.setVerticalScrollBarPosition(0.0); in the last step of the start method: the scrollbar scrolls always automatically to the end.

I there any solution to this problem?
