Description
If I apply Rasterize from GDALTools on a layer loaded double-clicking from File browser (shown on the legend as "filename.shp") this is not recognized as a valid data source. The same file, loaded with the old method, works smoothly
History
#1 Updated by Paolo Cavallini over 13 years ago
When loaded with the old method, it is shown as "filename", not as "filename.shp"
#2 Updated by Giuseppe Sucameli over 13 years ago
The problem is that the layer's source ends with
|layerid=0
Loading a OGR layer from QGis, the layer's source contains only the file path.
#3 Updated by Martin Dobias over 13 years ago
That is a legal URI - some data sources may contain multiple layers, in that case also QGIS shows a dialog that lets user to select "sublayers" to load - they also include the "|layerid=X" postfix.

So it's GdalTools plugin that has to check the path when selecting a layer from canvas.

Why don't add "|layername=Y" too?
There're GDAL tools that get a vector as input, they get layername instead of layerid to select the right sublayer.
E.g. gdal_rasterize (-l), gdalwarp (-cl)

Now the problem occurs only if the datasource contains more than one layer, otherwise the |layerid=X is not appended to the layer URI.

This still occurs?
Could you provide some dataset to reproduce it?
Thanks in advance
