Re: [udig-devel] Problem rendering GML files in uDig
|
Your GML file will need a schema; I think with the same filename (ie filename.xml and filename.xsd). The schema tells us how to parse the file (what tags extend gml feature and all that kind of stuff).
GML files are not really well supported; we have never found them in use very much and thus lack feedback and testing. There is a new gml parser in geotools we could use for uDig 1.2; but I imagine it will have the similar need for your gml file to be correct and have a shema (I think it is smarter and can look the your xml file for a URL location of the schema or something)
It is interesting to me that the file showed up in the catalog; if it can do that the BasicFeatureRenderer should of been able to draw it (using the DataStore api). Could you make a bug report with a small smaple of the file (one or two features?); other than that it would be time to look in your log and see if we can see some strack trace to give us a clue.
Cheers,
Jody

Hi,
I have downloaded uDig 1.2 M2 release and was playing around it.
But I have came across some behavior which I would like to bring to your notice.
1. When I was trying rendering gml file it doesn't get rendered and says "Renderingnull"
2. Then I tried with some other files and then this time file is appeared in catalog view but does not get added in layer view.
3. If I drag this gml file from catalog on map editor two layers get added in layer view but none of them get rendered.
4. When I click on one of the file so I can zoom to layer it says in status bar "Coordinate reference system of data is unknown. Unexpected behavior may result if it is not set."
5. When I tried to change the coordinate system the cast exception occurred. Screen shot of this added with this mail.
I am really not sure weather this is problem with data or of uDig. Or whether you know this already or fixed.
I also tried this in uDig 1.1 but it does not work there as well. So may be data I have is not right one.
If you have some test data or can show me link, please share it with me.
