Public bug reported:
When using the click_action_button of the Custom Proxy Object for
ActionSelectionPopover in an autopilot test, we get an exception in case
the action that gets clicked has the result of destroying the popover.
The bug is caused by the fact that, once the action item has been clicked, the
CPO method tries to access the autoClose property of the popover. However at
this point the popover might have been already destroyed, causing an exception.
A simple fix is to cache the value just before the click and refer to the value
after, as autoClose is unlikely to change as a result of the click.
For a real life example of this problem, imagine a ListView we pop up a
menu with an action that allows the user to delete the delegate pointed
at by the popup. This is very common case. The example below is the
simplest version of a test case that implements this. You can easily
create an AP test from this that reproduces the issue:
import QtQuick 2.4
import Ubuntu.Components 1.3
import Ubuntu.Components.Popups 1.3
ListView {
id: list
width: 800
height: 600
model: ["A", "B", "C"]
delegate: ListItem {
Button {
id: button
text: modelData
onTriggered: PopupUtils.open(popupComponent, button, {i: index})
}
}
Component {
id: popupComponent
ActionSelectionPopover {
id: popup
property int i
actions: ActionList {
Action {
text: "Delete"
onTriggered: {
var m = list.model
m.splice(popup.i, 1)
list.model = m
}
}
}
}
}
}
