Method Detail

apply

public void apply(javax.faces.view.facelets.FaceletContext ctx,

For each row in layout, exposes row variables and applies next handler.

Needs layout to be exposed in context, so works in conjunction with LayoutTagHandler.

Row variables exposed: RenderVariables.rowVariables.layoutRow and RenderVariables.rowVariables.layoutRowIndex, as well as RenderVariables.columnVariables.layoutColumn and RenderVariables.columnVariables.layoutColumnIndex, that act are aliases.

Throws:

IOException

javax.faces.FacesException

javax.el.ELException
