Hi,

I'm trying to use ftl files in order to customize a getFeatureInfo output, but since it was very easy to do it for KML styling, I get a problem when I try to acces simply the value of an attribute with a formula like :

            ${attributename.value}

that I used with KML. It seems that in a getFeatureInfo customization, we can't access the specific value of an attribute in that way ... am I wrong ?

Regards

Laurent

Hi Laurent,

I wouldn't also mind on getting some further information on freemarker/geoserver. Actually, I am doing quite a same in these days than you. With the help of the getFeaureInfo I am embedding some html in the current page. I did it as follows:

<#list features as feature>
  <#list feature.attributes as attribute>
    <#if attribute.name='yourattributename'>

do something with ${attribute.value}

</#if>
  </#list>
</#list>

Seem to be working, although I don't quite get it. Can't it be done easier?

Hi Mika,

Yes that's a good idea although I was trying to use the same way as for KML.

Cheers

Laurent

Hi Laurent,

Unfortunately it does not work quite the same as with KML. The reason is because with KML, the input to the template is a single feature, as with GetFeautreInfo, its a number of features. So first you must iterate through the features, and then get attributes. SOmethign like this:

<#list features as feature>
  'ATTRIBUTENAME' = ${feature.ATTRIBUTENAME.value}
</#list>

Hope that helps. There is more info available here:
