[OpenLayers-Users] poblems with style object in Layers object

[Andreas Hocevar]

Hi,

Style2 is only useful if you want to round-trip SLD with multiple
symbolizers per rule. For rendering vector layers, you have to use
Style.

Regarding your other questions: yes, there are several ways to define
styles and symbolizers. At the level of the renderers, we only work
with symbolizers (i.e. what you referred to as "style hash").

Does this help?
Andreas.
