The convert2dict of FullExtend is now:

<verbatim>
in ::WS::Utils::convertTypeToDict Client Latest_MapServer domNode054ED118 tns1:MapServerInfo domNode054ED640
...
Trying #3 domNode054ED118 selectNodes FullExtent
		 Found 1 FullExtent

*** Line 1628 Non-simple non-array
*** The abstract type FullExtend was replaced by tns:EnvelopeN
*** Before the change, we got here:
*** Type = {tns1:Envelope} typeInfoList = {0 0}

Entering convertTypeToDict Client Latest_MapServer domNode054ED19C tns:EnvelopeN domNode054ED640 

*** ::WS::Utils::convertTypeToDict
*** type=tns:EnvelopeN
*** isArray=0

Type = {tns:EnvelopeN} typeInfoList = {1 0} 

*** Apparently, tns:EnvelopeN is not present in the typeInfo.
*** So, the base type is evaluated and the asText is called.

Type = {tns1:Envelope} typeInfoList = {1 0} 
</verbatim>

So, apparently one step further.

Now, tns:EnvelopeN is not found in dict:

   *   typeInfo Client Latest_MapServer tns:EnvelopeN
   *   typeInfo Client Latest_MapServer Latest_MapServer:tns:EnvelopeN

Its wsdl snippet is:

<verbatim>
      <xs:complexType name="EnvelopeN">
        <xs:annotation>
          <xs:documentation />
        </xs:annotation>
        <xs:complexContent mixed="false">
          <xs:extension base="Envelope">
            <xs:sequence>
              <xs:element name="XMin" type="xs:double" />
              <xs:element name="YMin" type="xs:double" />
              <xs:element name="XMax" type="xs:double" />
              <xs:element name="YMax" type="xs:double" />
              <xs:element minOccurs="0" name="ZMin" type="xs:double" />
              <xs:element minOccurs="0" name="ZMax" type="xs:double" />
              <xs:element minOccurs="0" name="MMin" type="xs:double" />
              <xs:element minOccurs="0" name="MMax" type="xs:double" />
              <xs:element minOccurs="0" name="SpatialReference" type="SpatialReference" />
            </xs:sequence>
          </xs:extension>
        </xs:complexContent>
      </xs:complexType>
</verbatim>

So lets look what was found in the wsdl:

<verbatim>
% dict get $::WS::Utils::typeInfo Client Latest_MapServer tns:EnvelopeN
key "tns:EnvelopeN" not known in dictionary
% dict get $::WS::Utils::typeInfo Client Latest_MapServer tns1:EnvelopeN
definition {
  XMin {type xs:double comment {}}
  YMin {type xs:double comment {}}
  XMax {type xs:double comment {}}
  YMax {type xs:double comment {}}
  ZMin {type xs:double comment {}}
  ZMax {type xs:double comment {}}
  MMin {type xs:double comment {}}
  MMax {type xs:double comment {}}
  SpatialReference {type tns1:SpatialReference comment {}}
}
xns tns1
abstract false
</verbatim>

So, there is a wrong namespace, "tns1" instead "tns"...

Stop here today. Maybe someone may comment...

Thank you,
