Hi ,
I am using the 1.5 (rc1) owsExplorer client with a FeatureSelectHandler in
my config. I have modified the stylesheet that parses my WFS capabilities
doc so that I can use a modified contextEditor and stylesheet to add a wfs
layer to my OWS context doc giving me the ability to save wfs layers to a
user's OWS for reconstructing customized maps later. Additionally the
wfsCap stylesheet adds a link for querying each layer using <a
href="javascript:config.objects.{$modelId}.setParam('wfs_GetFeature','{$name
}')">query</a> which adds the same layer for querying, but with a hollow
fill to the FeatureCollection where the FeatureSelectHandler allows for
selections. In other words a type of acetate layer for capturing mouse
events and returning attributes from the layer. All of this works fine,
except once the query is invoked there doesn't seem to be a way of getting
rid of the query acetate. Clicking other buttons like zoom or pan doesn't
release the mouse capture from the query layer. I have been playing with
another link for the layer that stops the query by calling a function i.e.
javascript:config.objects.featureHighlighter.dropAcetate(?) in
FeatureSelectHandler.js for unregistering the events and setting
this.mbFeatureSelectHandler to null. So something similar to
OpenLayers.Feature.layer.events.unregister('mousedown', this,
featureSelectHandler.onClick);
OpenLayers.Feature.layer.events.unregister('mousemove', this,
featureSelectHandler.onHover);
But I have had no luck whatsoever. At that point OpenLayers.Feature.layer
has no properties. I am unsure which object that I could send from the
stylesheet to be able to unregister the events against. It has to be the
layer but again I am unsure how to get the layer. And besides shouldn't
FeatureSelectHandler let go of the mouse events when you use another tool?
Any help would be greatly appreciated.
