Hi Kemin and all,
Thanks for your help. I have finally managed to make it work... but I must admit that I can not explain exactly why.
I have :
- fully reinstalled Eclipse with Mars 4.5 version (I had Luna so far) with its SAP HANA Cloud Platform Tools,
- defined a new SapUI5 project and imported the WebIde Master-details sources,
- on a different computer..........,
- and no I have not make the change as described in step 8.
I have also imported the source directly into the project's root instead of the WebContent folder as you can see on the pic below.
And "voilà"!
J.
