[Gvsig_english] FW: bugreport: symbols-quantities-intervals fail with negative values

[Francisco José Peñarrubia]

Hi Ben.

Maybe you remember that there was a limitation to use joined fields in 
legends. I did some changes in order to allow it, but in this case 
(Expresion symbology), I couldn't make the changes because then, I would 
need to touch code inside GDBMS, and it was too risky been in the last 
steps of estabilization. So, we decided to keep this bug inside, because 
in 2.0 release the joined tables behave differently.

Cheers.

>> Dear all,
>>
>> I have a shape file with a column having positive and negative values with 3 decimal places. When I apply symbols-quantities-intervals to map classes (natural intervals) I get two classes with negative values. 
>> -17.91 - -2.555
>> -2.55 - 2.55
>> 2.59 - 9.08
>> 9.11 - 20.05
>> 20.3 - 51.6
>>
>> The classes are computed correctly. If I press accept the classes are visualized correctly but I can't edit the properties anymore. A windrow appears saying: java.lang.ArrayIndexOutOfBoundsException: 5
>>
>> If I compute 5 classes a say apply the class with the lowest values disappears and only 4 classes remain. The feature of the lowest cklass are no longer visualized.
>>
>> I someone is interested I can send the shape file.
