issue with property in REST DSL in blueprint context - Camel 2.19.1

[claud...@gmail.com]

Hi,

I'm trying to update from Camel 2.16.3 to 2.19.1 and experience issues 
using properties in the REST DSL in blueprint context.

I have the following config:

        <rest 
path="patient/{patient_id}/events?cutoff_timestamp={cutoff_timestamp}&amp;limit={limit}" 
produces="application/json" consumes="application/json">
            <get bindingMode="off">
                <param name="patient_id" type="path" dataType="string" 
required="true" />
                <param name="cutoff_timestamp" type="query" 
dataType="long" required="false" />
                <param name="limit" type="query" dataType="integer" 
required="false" defaultValue="{{vel.rest.default.rowlimit}}" />

For the param "limit" the property "{{vel.rest.default.rowlimit}}" used 
in attribute defaultValue seems not to get replaced as I receive the 
following exception:

   java.lang.NumberFormatException: For input string:
   "{{vel.rest.default.rowlimit}}"


I googled for known issues but didn't find anything. Has anything 
changed related to using properties in REST DSL? It previously worked 
(2.16.3) and in other places e.g. in the route the syntax 
"{{propertyName}}" works...

Cheers
Claudia
