A little bit tricky to find, but I got it

Thanks a lot for the many new features.

Finally I found that myself. For others, look in the same place, where you can delete links between objects in editor.

Still, could someone explain this feature and its possible functions for me?

You can branch the flow into an 'error condition' tree part.
Like "on error goto THERE and do THIS". Your own error handling
instead of the message in Android 's notification bar.

You can test this feature using a flow that produces some errors:

-trigger is not required
-condition 'Expression' without a script (the condition will fail when executed)
-->true: action 'Vibrate'

-manually execute the flow (menu->Execute). You should get an error in the notification area and the flow stops at the condition.
-select the connection between condition and action, press the edit-button and change the type to 'Exception'
-note that the appearance of the connection changed to a red dashed line
-manually execute the flow again. Action 'Vibrate' should be executed since you defined that this action should handle an exception case.

This exception feature can be handy when you have actions that can fail under some conditions (no network available, network seems to be available but data can not be transferred etc.) to define your own retry-strategy or to show a custom error message.

Thanks! You helped to understand it a lot.

Hello,

I'm using "Exception" to keep my flow going even if it can't determine its location by using gps or wifi.
In that case user may (and should) receive something anyway so "Exception" works fine.

However because it is not possible to put two links from object "A" to object "B" I have to create two similar objects "B" just to be able to handle both normal flow and "Exception" flow.
(please see attached flow if my explanations are unclear - it is just a draft but you'll see the idea).


Is there any better way of doing this? Something like "ignore errors and keep going" option for a section?

Thank you.

You can create multiple links, but they have to be different type.

Create the first link and change it to "exception". Then press first element. Now you see various buttons around out. Drag the plus button to the second element. This creates the second link you need.

Pro tip:If you tap the link, you'll see dots around the elements it's linked to. Pressing those dots will change the position where the link connects to elements. Changing these will help you to make much more clear and readable flows.

Hi MURTUMA,

I realised that it might be a "glitch" of the GUI - I actually can put both "normal" and "exception" link from element A to element B, but the "exceptional" link should be created first - after that you are able to put "normal" one.

However if you create a "normal" one (which is by default and anticipated) FIRST - then you are not able to put "exception" to the same element.

P.S.: Thank you for the tip, it is definitely helpful!!
