<input type="text" id="$descriptorId" name="$descriptorId" value="#if($request.get($descriptorId))$request.get($descriptorId)#else$descriptor.defaultValue#end"/>
#else
<input type="text" id="$descriptorId" name="$descriptorId"#if($request.get($descriptorId))value="$request.get($descriptorId)"#end/>into
<input type="text" id="$descriptorId" name="$descriptorId" value="#if($request.get($descriptorId))$escapetool.xml($request.get($descriptorId))#else$descriptor.defaultValue#end"/>
