I have solved this in a slightly hacky way ....
woody-model:
. . .
<wd:booleanfield id="publishable">
<wd:label><i18n:text i18n:catalogue="local">label.publishable</i18n:text></wd:label>
<wd:hint><i18n:text i18n:catalogue="local">hint.publishable</i18n:text></wd:hint>
</wd:booleanfield>
<wd:output id="scenariocount">
<wd:label><i18n:text i18n:catalogue="local">label.scenarios</i18n:text></wd:label>
<wd:hint><i18n:text i18n:catalogue="local">hint.scenarios</i18n:text></wd:hint>
<wd:datatype base="string"/>
</wd:output>
. . .
woody-binding:
. . .
<wb:value id="publishable" path="publishable"/>
<wb:value id="scenariocount" path="string(count(scenarios))" direction="load"/>
. . .
woody-template:
<wt:widget id="publishable"><wi:styling type="conditional" on="scenariocount"/></wt:widget>
<wt:widget id="scenariocount"/>
XSLT:
<!-- conditional boolean field : checkbox and label in seperate cells -->
<xsl:template match="wi:booleanfield[wi:styling/@type='conditional']" mode="group-columns-content">
<xsl:variable name="condition" select="wi:styling/@on"/>
<tr>
<td><xsl:apply-templates select="." mode="label"/></td>
<td>
<input id="[EMAIL PROTECTED]" type="checkbox" value="true" name="[EMAIL PROTECTED]" title="{wi:hint}">
<xsl:if test="../wi:[EMAIL PROTECTED]/wi:value != '0' "> <!-- Yucky XPath !! -->
<xsl:attribute name="onclick">this.checked=this.defaultChecked;alert('This Album is featured in a Scenario, it cannot be made Private anymore.');</xsl:attribute>
</xsl:if>
<xsl:apply-templates select="." mode="styling"/>
<xsl:if test="wi:value = 'true'">
<xsl:attribute name="checked">checked</xsl:attribute>
</xsl:if>
</input>
<xsl:apply-templates select="." mode="common"/>
</td>
</tr>
</xsl:template>
It works for now ..... but is very application specific, and I would not want to do anything more complicated using this technique.
Thanks
