[FIX] [10.0] 2d widget fixes

[richard-willdooit]

Fixes display and input bugs in 2d widgets.

• dataset.read_ids needs fields otherwise it returns no data
• renderElement was loosing the change event handler
• add standard odoo classes for read / edit mode hiding of alternate values
• effective_readonly_change was switching same nodes twice

Thanks for the patches. Maybe you can consider also the issue #697

[hbrunn]

how easy it is to overlook stuff in reviews...

[richard-willdooit]

@pedrobaeza I actually don't use it with totals in my implementation. I don't think the totals render very well in version 10, but decided not to try and add this "enhancement", and I just did the fix to ensure correct recomputing.

[pedrobaeza]

Thanks again, Richard, can you please make a last change that is modifying module version number for reflecting the evolution of the module?

[pedrobaeza]

Can I squash at merge? As the only way to try here on runbot is to merge the PR and rebuild runbots that use it, I will merge. I would like to have demo data inside the module, but that would require to add code that can't be avoided when no demo data. @hbrunn do you have any possible idea?

[hbrunn]

first I thought you mean something like this, but now I understand you mean adding something that causes a field/wizard/view exist with demo=1 so that we can check stuff in runbot simpler?

Never tried this, but I had to detect runbot before, and maybe we can say

import socket
import os
if socket.getfqdn().endswith('odoo-community.org'):
    import my_demo_model

in models/__init__.py?

[pedrobaeza]

@hbrunn thanks for the suggestion, but I don't really like a lot that because that will mean that I can't try in other DB except OCA runbot. I will think in this in my spare time and see if there's other option.

[hbrunn]

if you always want to add stuff in demo mode, using a hack like https://github.com/OCA/server-tools/pull/876/files#diff-ded7038d0dcfffc218c449b206263ebfR38 to get the current database's cursor, and then check if it has demo data enabled might work

[pedrobaeza]

That's something I like more 😄 but as said, to be tried on my spare time, which is very little...
