null pointer exception running vectortoraster #93

Closed sbalasub closed 10 years ago

sbalasub commented 10 years ago

The inputs were features:sf:streams rasterwidth: 1000 rasterheight: 2000 attribute(Attribute name to use for the raster cell values):somename

On running vectorto raster I get java null pointer exception. This could be on the geoserver side.

bartvde commented 10 years ago

@sbalasub somename is that a valid attribute of this dataset?

sbalasub commented 10 years ago

@bartvde I thought thats the name to use for the raster cell values and can be anything. I tried using the_geom, cat etc. with the same result (exception).

bartvde commented 10 years ago

it seems you can only use attributes that are numbers @sbalasub

I'll update the server you can see more easily the error messages

sbalasub commented 10 years ago

@bartvde yes I saw that but not sure what number it refers to. a random number just throws the java exception.

bartvde commented 10 years ago

Will investigate a bit more

hey I now get a download using DP0010001 on the states layer

sbalasub commented 10 years ago

cool! Closing this ticket then.

bartvde commented 10 years ago

the download is a completely black TIFF file, but I'm not sure what values are in that column

I do see a related issue though, that is if I try and change an input (the field name in this case), I do get a null pointer exception, and I see the request is empty somehow
