wms - OpenLayers not refreshing a layer

I have a problem with refreshing layers. I have WMS and WFS layers from one source. I edit WFS and after do wms_layer.redraw(true) but the layer redraws only after zoom in or zoom out.

Same with WFS. I have wfs_layer.visibility=false and do wfs_layer.visibility=true wfs_layer.refresh({force:true}). And layer refreshes only after zoom in or zoom out.

For doing these operations do I have to do something special?

Answer

For redraw WMS layer use redraw method of OpenLayers.Layer.HTTPRequest. For example:

wms_layer.redraw(true);

Refresh method doesn't pass any parameters, so for redraw wfs layer use the following syntax:

wfs_layer.refresh();
