TaskState after sending redirect

trungdv — Thu, 29 Dec 2016 05:04:17 -0500

Hi all

i have a sample process like this: In there i have a ivy task, after i close user dialog, i want to redirect to another start process by using HttpResponse (not use endpage element). With some small investigation i see the task state after i send redirect still be RESUMED,

If i change this process to continue with endProcess element (after script httpRedirect), it throw exception:

java.lang.IllegalStateException: Cannot call sendRedirect() after the response has been committed
    at org.apache.catalina.connector.ResponseFacade.sendRedirect(ResponseFacade.java:494)
    at javax.servlet.http.HttpServletResponseWrapper.sendRedirect(HttpServletResponseWrapper.java:138)

    at ch.ivyteam.ivy.bpm.engine.internal.BpmEngine.handleNormalRequest(BpmEngine.java:191)

So, to deal with this case, i need to reset task manually?

How to get BpmEngine belong to a Process Model Version

trungdv — Wed, 28 Dec 2016 02:52:32 -0500

Hi all, in module A, I have a function that return a BpmEngine as:

IBpmEngine engine = DiCore.getGlobalInjector().getInstance(IBpmEngine.class);

With this line of code i get instance which belong to module A somehow.

Now i also want to get IBpmEngine from other related modules (example: my module A depend on module B). I check the code then see each BpmEngine has a different id, combine between project model name and project model version: (class ch.ivyteam.ivy.bpm.engine.internal.BpmEngine)

this.id = "BPM engine " + this.getProcessModelVersion().getApplication().getName()
                + "/" + this.getProcessModelVersion().getVersionName();

Is there anyway to get BpmEngine of other related modules?

P/S: somehow this question is related to this post where i want to register listener for other module.

Can we monitor ivy process programmatically?

Hi all

i have a sample callable subprocess as below:

With SubProcessCall util, i can trigger to run it and also control input&output. So i want to go a step futher to monitor that such process. Is there any API or util that could help me to monitor this process? like when process come to step Do first thing, i will be notified and i can access variable in/out or just simple logging out the name of that ivy element.? Also the same question for other kind of process (sub process/start process/...)

Thanks all
