Issues when handling integer fields #1

Closed apryet closed 10 years ago

apryet commented 10 years ago

First of all congratulation for this plugin. But unfortunately, it crashes when handling field of type "integer"

Error message below :

Thanks. I see the problem is that it is ignoring integer values and then dying when it finds no data values. I've uploaded a new version which hopefully fixes this (did for me at least :-)

Great. Just a question : when I clone your project on git hub, the plugin contour is not suitable for Qgis 2.0. Do you intend to apply the small updates for this plugin to be compatible with the last version ? Thanks !

Did you clone from master - I see I've left an old qgis2 branch there, which was a development branch now merged to master. I'll tidy that up (and put in a 1.8 branch)
