[Bug 1553090] Re: Binding loops in implicitWidth with OTA 10 landing

 

This bug was fixed in the package ubuntu-ui-toolkit -
1.3.1984+16.10.20160527.2

---------------
ubuntu-ui-toolkit (1.3.1984+16.10.20160527.2) yakkety; urgency=medium

  [ Christian Dywan ]
  * Slimmer frame for TextFields: 0.5dp. Fixes LP: #1578190.

  [ Albert Astals Cid ]
  * Add override
    The override specifier (since C++11) specifies that a virtual function
    overrides another virtual function. In a member function declaration or
    definition, override ensures that the function is virtual and is overriding
    a virtual function from the base class.

  [ Tim Peeters ]
  * Fix reference error in PullToRefreshStyle. Fixes LP: #1582843
  * Mark Tab, Tabs, TabBar, PageHeadConfiguration, PageHeadSections,
    PageHeadState, ToolbarButton, ToolbarItems as deprecated in the
    documentation. Fixes LP: #1566735, LP: #1566741.

  [ CI Train Bot ]
  * Resync trunk.

Bug description:
  The simple code

  import QtQuick 2.4
  import Ubuntu.Components 1.3

  AbstractButton {
      implicitWidth: childrenRect.width
      implicitHeight: childrenRect.height
      Label {
          id: titleLabel
          text: "HOLA CARACOLA"
      }
  }

  is giving

  file:///home/tsdgeos_work/test/1.qml:4:1: QML AbstractButton: Binding loop detected for property "implicitWidth"

  file:///home/tsdgeos_work/test/1.qml:4:1: QML AbstractButton: Binding loop detected for property "implicitHeight"

  with the OTA 10 landing as of today.

  This works fine without that landing and i think it's valid code that
  should not be giving out warnings like this.
