[Users] control which fields are displayed in my Geoext popups

[Hugo]

Hi Robert,

What you can do in fact is:

- Make a geoserver template that will return your data in JSON format
- Then, process the data as you wish on the client side (this is, using
GeoExt)

Below you can find an example of content.ftl that is returning the data in
JSON format.

[{
<#assign i = 0 />
<#list type.attributes as attribute>
<#if (i >= 0) && (!attribute.isGeometry)>
"${attribute.name}":
<#list features as feature>
<#assign k = 0 />
<#list feature.attributes as attribute>
<#if (k = i) && (!attribute.isGeometry)>
"${attribute.value}"
</#if>
<#assign k = k+1 />
</#list>
<#if attribute_has_next>
,
</#if>
</#list>
</#if>
<#assign i = i+1 />
</#list>
}]

hope this helps.
Cheers,

Hugo
