Charles is bombing us with questions that help me to see what is missing in the docs. When working at the More about layouts page I realized how complicated it is when you want a table view that opens directly into the detail window instead of a list window. You need to say:

@classmethod
def get_default_action(cls):
    return actions.ShowDetail(cls.detail_layout)

The Actor.get_default_action method is now being called when all other standard actions have been bound. As a result, an application developer can now simplify the code for saying that a table view should not have any tabular view:

@classmethod
def get_default_action(cls):
    return cls.detail_action

This apparently minor change caused an avalanche of changes in the deepest inner parts of Lino. Hic sunt dracones. There is danger of having introduced bugs that slip through the test suite.

I removed the mysterious Actor.default_elem_action_name attribute because (1) I don’t understand its purpose (it’s obviously used to customize the action_name for the detail_action but I can’t remember why we want this) and (2) because I suspected it to be the reason why React doesn’t show the system.About dialog. At the moment I do not yet remove the default_list_action_name, this might come later.

Side effects: I discovered that lino_xl.lib.ledger.Situation table was no longer used, so I removed it. I formulated and then fixed #4075, which required me to extend the API for lino.core.plugin.Plugin.get_quicklinks(): it can now return a dict.

I had the following warning when I pushed to react:
