[Gwt-openlayers-devl] more on WFS

[Edwin C. <com...@gm...>]

hi all,

I moved the redraw function from Layer to HTTPRequestLayer. Are there
any objections to that?

The redraw function is a function of HTTPRequestLayer and subclasses
in OpenLayers.

I guess it got moved to Layer for convenience, but when you have Layer
and want to call redraw you should actually first check if it is a
Layer on which redraw can be called.

For example:

WMS wmsLayer;
String layerClassName =
Layer.narrowToOpenLayersObjectWrapper(layer).getClassName();
if(layerClassName.equals(Layer.WMS_CLASS_NAME)){
    wmsLayer = WMS.narrowToWMS(Layer.getJSObject());
}

When you know it's a WMS layer then you can also simply do:

WMS wmsLayer = WMS.narrowToWMS(layer.getJSObject());

I will have to describe that on the users wiki...

Greetings,
Edwin
