WFS - decimal feature attributes too restrictive for decimal places
-------------------------------------------------------------------
Key: GEOT-845
URL: http://jira.codehaus.org/browse/GEOT-845
Project: GeoTools
Type: Improvement
Components: xml, wfs
Environment: JRE 1.5, Win XP, udig version 1.1M7
Reporter: Michal Galet
Assigned to: David Zwiers
The exception is thrown when trying to parse large attributes in WFS response
like:
<ber:at_26071>406446400000000000360</ber:at_26071>
Where attribute is defined(DesctibeFeatureType) as:
<xsd:element name="at_26071" nillable="true" minOccurs="0">
<xsd:simpleType>
<xsd:restriction base="xsd:decimal">
<xsd:totalDigits value="38"/>
<xsd:fractionDigits value="0"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
There is no restriction in WFS1.0 specification for decimal length, however it
could be good to check the data type and consider using java.math.BigDecimal or
other suitable data type. I haven't found where is the max number for decimal
types defined.
