[Gvsig_english] Error on point label features

[Francisco José]

Hi.

It seems there is a Null Value in height field. Line 182 from FLyrText:

                            NumericValue height = (NumericValue) 
ds.getFieldValue(i, idFieldHeightText);

May be we shoud catch this kind of exceptions in the future.

Until then, you can check your point data and make sure that the height 
text field has rigth values.

Thanks for the appointment!!.

Have fun.
