[Qgis-developer] Problem adding non-cached WFS layer using PyQgis

[mattwalsh]

Hello,

>From my plugin I am able to add a non-cached WFS layer to QGIS using the
following code:

c_extent = self.canvas.extent()
str_c_extent = c_extent.toString()
str_c_extent = str_c_extent.replace(" : ", ",")
url = site_url + "wfs.ashx?id=" + token +
"&SRSNAME=EPSG:27700&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&TYPENAME="
+ layer + "&BBOX=" + str_c_extent
iface.addVectorLayer(url, title, 'WFS')

The layer is added to the ToC fine but does not fetch any features ('show
feature count' is 0). Panning the canvas etc does not cause the layer to
request features either. 

If I add the same layer in using QGIS GUI (unchecking the 'cache' button)
then each pan/refresh will request the features for the new canvas extent.

The layer source of the WFS added by PyQgis and QGIS GUI are identical when
looking at the properties.

I have tried this in both 2.4 and nightly build. This was not an issue in
2.2 with exactly the same code.

Could anyone suggest fix/work around to this problem I could try?

Manys thanks
Matt
