[Building Sakai] XSD Form Validation: "Value [Ljava.lang.String; @3ee9280f for field XXX must be in enueration"

[will trillich]

Short version:

The error message is "*Value [Ljava.lang.String;@3ee9280f for field XXX must
be in enueration*" and it happens when we try to submit a form that has a
checkbox-group. Any ideas what that means and/or how to get past it?

Long version:

We're trying to use a custom XSL field-renderer to produce the create-form
HTML by modifying/overriding <xsl:template name="select-field">:

The field will be specified in XSD as an
<xs:element><xs:simpleType><xs:restriction base="string"> with a bunch of
<xs:enumeration> values inside it. Each such value is to be a checkbox
instead of a radio box. To facilitate this we've opted to allow the XSD to
include an extra element *<xs:documentation source="toggles" /> *that will
'trigger' the checkbox-group.

The 'canned' version from formFieldTemplate.xslt includes this test:
<xsl:when test="@maxOccurs !='1' and
count($currentSchemaNode/xs:simpleType/xs:restriction[@base='xs:string']/xs:enumeration)
&lt;= $htmldeterm">
and when that's true, the checkbox-group code that we want to run gets
executed. But that only runs when maxOccurs isn't 1 and the number of
enumerated values <= 2. We want it to run when the "toggles" source is
specified in the XSD, so we copied the code up to the top of the
<xsl:choose> statement and made this the first test:

<xsl:choose>
            <xsl:when test="*
$currentSchemaNode/xs:annotation/xs:documentation[@source='toggles']*">
               <!-- this will force a checkbox group control -->
               <fieldset>
                  <xsl:attribute name="class">
                     <xsl:text>serensoft-toggles </xsl:text>
                     <xsl:call-template name="fieldClass">
                        <xsl:with-param name="schemaNode"
select="$currentSchemaNode" />
                        <xsl:with-param name="baseType"
select="'osp-radcheck'" />
                     </xsl:call-template>
                  </xsl:attribute>
                  <legend>
                     <xsl:if test="$currentSchemaNode/@minOccurs='1'">
                        <span class="reqStar">*</span>
                     </xsl:if>
                     <xsl:call-template name="produce-label">
                        <xsl:with-param name="currentSchemaNode"
select="$currentSchemaNode" />
                     </xsl:call-template>
                  </legend>
                  <xsl:for-each
select="$currentSchemaNode/xs:simpleType/xs:restriction[@base='xs:string']/xs:enumeration">
                     <div class="checkbox">
                        <input id="{$name}-{position()}"
name="{$name}-{position()}" type="checkbox">
                           <xsl:attribute name="onChange">
                              (this.checked==true) ?
document.getElementById('<xsl:value-of select="$name" />-<xsl:value-of
select="position()" />-w').value='<xsl:value-of select="@value" />'
                              : document.getElementById('<xsl:value-of
select="$name" />-<xsl:value-of select="position()"
/>-w').value=''</xsl:attribute>
                           <xsl:if test="$currentNode = @value">
                              <xsl:attribute
name="checked">checked</xsl:attribute>
                           </xsl:if>
                        </input>
                        <label for="{$name}-{position()}">
                           <xsl:value-of select="@value" />
                        </label>
                        <input type="hidden">
                           <xsl:attribute name="name">
                              <xsl:value-of select="$name" />
                           </xsl:attribute>
                           <xsl:attribute name="id">
                              <xsl:value-of
select="concat($name,'-',position(),'-w')" />
                           </xsl:attribute>
                           <xsl:attribute name="value">
                              <xsl:if test="$currentNode = @value">
                                 <xsl:value-of select="@value" />
                              </xsl:if>
                           </xsl:attribute>
                        </input>
                     </div>
                  </xsl:for-each>
               </fieldset>
            </xsl:when>

Any ideas what the form-validator is really complaining about?

This is in Sakai v2.7.1.
