renderFisheye

protected void renderFisheye(org.apache.tapestry.IMarkupWriter writer,
                             org.apache.tapestry.IRequestCycle cycle,

                             List fisheyeIds)

Handles starting/ending the main outer fisheye widget div tags. Also handles checking breakOnIndex parameter to enable multiple list renders.

Parameters:

writer -

cycle -

currIndex - Current index of list iterating on

fisheyeIds - List of unique element ids for each fisheye, will be appended to if current iteration requires creating a new fisheye.
