Hi Jean-Yves,
Thank you so much for chiming in! I'll check if we can switch to frontend selection, but as the corresponding screen deals with invoices, a lot of refactoring will be involved, so not sure this can be accepted (on the other hand we discovered that only 1 line of javascript code could be added to scripts_.oo_tableview.js in order to fix this behavior so we might take this path instead).
Anyway: as this doesn't seem to be considered a bug because removing content selection allows to navigate between cells with left/right arrows, by any chance do you know what it is for? I mean, what can you do once you've navigated to a cell? There must be a purpose for navigating... which one is it? As it doesn't make any sense to me at the moment to be able to surround a cell with dotted lines if I cannot do anything at all, I'm wondering why SAP chose the dotted lines instead of the content selection. There must be a good reason for removing something so widely used over the Internet: I'm looking desperately for this reason to be able to explain it to 3 customers of mine. So if you have the answer, I'm begging you to share it :-)
Thank you so much,
nicolas.
