Hi Christian: We are entering a very busy time of year (leading up to the foss4g conference); so many of the developers will be unavailable except to their paying customers.
Andrea did offer to look at this issue for you ... here is how you can help him do so: - create a jira issue - attach your program below (if it can be used to reproduce the problem) - include a sample shapefile (or properties file) with some data so the issue can be shown and debugged It is one of the cases where you (who have the problem) are in a much better position to reproduce it then us on the development team. While the developers can sometimes spare a couple of hours to work on the really well defined issues (reproducible as above; or with a patch and test case) it is unwise for us to promise anything timely. Failing that; if you are approaching a deadline or something; please consider looking at the opengeo support page; or walk through the problem yourself with the debugger and see if you can produce a patch? You are creating a point and a text symbolizer (so that works around one issue that was reported). I really recommend you look at text symbolizer that is produced in the debugger to see if has all the fields field in the way you expect? I don't always trust the factory methods to work as I personally expect them to. Cheers, Jody On 21/06/2010, at 6:12 PM, Christian Dubray wrote: > Hi, > > Okay, no answer until now.
