Displaying a remote task flow in a pop up/dialog in the calling application

[Amit Tiwary]

Hi,

 

We are exploring the possibility of remote task flow call as an integration strategy among applications. As we explore remote task flow more, we find this facility very limiting.

• Remote taskflow can't be invoked as a dialog(?).
  

I raised a query in the forum. http://myforums.oracle.com/jive3/thread.jspa?threadID=976285

 Answer from the forum is "remote task flow and run as dialog are mutually exclusive".

This will limit the calling application to do a full page transition to the remote task flow page and then come back.

Is there any known way in which this limitation can be overcome?

• TaskFlow Call Activity cannot invoke remote taskflow inside a Region.                                                           
  

This limitation will come in the way of showing the called remote task flow in a region on even a pop up in the calling application.

Is there any possible way(s) where the calling application can display and allow the user to interact with the called remote task flow in the scope of currently displayed UI (pop up/dialog)?

Thanks,

Amit

Hi Amit,

First, your link is broken.

Second, I did not understand the questions well, maybe because I was not able to read your posted link, but I just wanted to ask if you happen to look on how the Oracle BPM worklist and workspace app, which are included a standard Oracle SOA 11g  installation, utilizes remote task flows to display task details.

regards,

Amit,

* remote task flow page and then come back. Is there any known way in
which this limitation can be overcome? *

No. Note that this question is not really one I would epect on the EMG
but the OTN forum. You got your answer there as well, which is why I
don't understand the double posting here. Anyway, the current
implementation of remote task flow doesn't allow the remote task flow
to display in a region for the following reasons

- Its designed as a Java EE application that receives and returns teh
calling application state by its state token
- Its invoked from a task flow call activity
- Remote task flows use JSPX documents that don't run in a region
- remote task flow navigation only restores the top level page state
(no nested region state if called e.g. through a parent activity)

To integrate a remote task flow in a popup you could use an inline
frame. However, this is not really an integration in the sense you
want it.

In the longer terms, there are plans to allow remote task flows to
show in ADF regions (as you requested it) and IMO it makes sense to
have it especially in respect to ADF application architecture.
However, I have no release date for this feature. So for now we need
to leave it with that today (and probably in 12c) the limiting factor
is that remote task flows cannot be exposed in regions.
