Fiori Launchpad - intent based navigation from POWL to GUI - results in logoff

[TomVanDoo]

Hello,

I have a rather annoying issue with Intent based navigation from one UI-technology to another.

We use the Netweaver Business client (7.70 PL 10).

system is S/4Hana 1610 (yeah, I know. it's old)

We have FES 6.0 with UI5 1.71

We start the Fiori launchpad embedded in the NWBC.

From the launchpad, we start a POWL in a new tab.

So far so good.

Now, from the POWL, we can launch transaction VA01 (Intent based navigation, GUI mode)

the navigation itself works perfectly, and opens a new tab (explace) and shows VA01, in SAPGUI

But notice what happened to the tab that had the POWL. It navigated back home.

After some digging, I found out that it triggers a USR_LOGOFF after the Intent based navigation.

In the NWBC logs, I alos found that NWBC seems to receive 2 navigation instructions. 1 for the SalesDocument-create, and 1 to go to shell-home (could be a cause, or a consequence. not clear yet):

Any ideas how to prevent/fix that?

root-cause:

It all seems down to these handfull lines of code. When I debug the "isInitialNavigation" to return false, it all works as it should. But since it's an explace navigation to begin with, it always returns true.

I feel like this should also check for the current hash-type. If it's a embedded application like webdynpro, it should _NOT_ navigate to the root.
