Binding loop detected for property "width" when I add 20 to width

[wspilot]

Hi,
When I do:
@width : childrenRect.width + 20@

I get the
@Binding loop detected for property "width"@

error.
Without the "+ 20" no error.
Still, the app works OK: the 20pix do get added to the width correctly.
Should I ignore the error message?
Thanks.

I believe you get this error because childrenRect.width changes when width changes. So width = childrenRect.width + 20 -> childrenRect.width changes because width changes -> width changes because childrenRect.width changes etc.

Best not to ignore this.

Thanks, but
childrenRect.width can (should) not change because it is not dependant on its parents width.
If it were then we would have a binding loop.
