Description

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}}"
