dojo.html.placeOnScreenAroundElement FIX

[[email protected]…]

It is obvious when using the ComboBox? widget!

Reason: when the function calls for the absolute position of the node, it gets the upper-left content corner, ignoring the border and margin. Then it calls for the marginBox to get the height and width.

Therefore, when you have a border around the node this happens (e.g. BL, vertical, border: 1px, offsetTop:9px, height: 10px):

top = node's content absolute top = 10px (offsetTop + top border + top margin)

height = node's content height + horizontal borders + horizontal margins = 12px

Ends up positioning 23px from top (22px + another pixel so that they do not overlap), when in fact our node ends (content+border) at 21px from top. The new node that is positioned BL gets to be 2px away.

Do you have CLA on file please?

[[email protected]…]

I have just found out what is CLA, through the dojo-interest mailing list.

I will need to send the CLA by snail mail to the Dojo Foundation, right? and then code pieces will be liable to be included in the main trunk?

[liucougar]

faxing it is another option

fixed in r5014

a more thorough approach is taken
