Warning rebinding DragClientBundle - encountered '=' was expecting...

GoogleCodeExporter commented 9 years ago

Hi Allan,

I'm getting the following warning, not sure if it's even a bug or not.
It happens in Quirks mode at least.
I'm using GWT 2.6.1 and gwt-dnd 3.3.3
This is on Mac (Mavericks) running in Eclipse Development mode
Using Firefox 26

The line https://github.com/fredsa/gwt-dnd/blob/master/DragDrop/src/com/allen_sauer/gwt/dnd/client/util/gwt-dnd.css#L63: filter: alpha(opacity = 30) causes the problem. It seems to be a weakness of the GWT Resource Parser because it should be valid CSS. Am I right by saying that it is only needed for IE support? If true the best solution may be to remove the alpha style. Can this be done? Would be nice!

Right, that alpha filter for there IE only.

It looks like IE8 and below only support alpha filter. Once we get to IE9+ targets we could drop it.

mcimbora commented 8 years ago

It should be enough to wrap the alpha inside literal [1] function, i.e. filter: literal("alpha(opacity = 30)")
