Example 1 with FaceletStateValueExpression

use of org.apache.myfaces.view.facelets.el.FaceletStateValueExpression in project myfaces by apache.

the class ForEachHandler method setVar.

private void setVar(FaceletContext ctx, UIComponent parent, String uniqueId, String base, String v, ValueExpression ve, ValueExpression srcVE) {
    AbstractFaceletContext actx = ((AbstractFaceletContext) ctx);
    PageContext pctx = actx.getPageContext();
    if (srcVE != null) {
        FaceletState faceletState = ComponentSupport.getFaceletState(ctx, parent, true);
        faceletState.putBinding(uniqueId, base, ve);
        // Put the indirect EL into context
        ValueExpression fve = new FaceletStateValueExpression(uniqueId, base);
        pctx.getAttributes().put(v, fve);
    } else {
        pctx.getAttributes().put(v, ve);
