---------------------------------------------
[~andreufontb], isn't it <toD uri="\{{example}}"/> ??
> toD doesn't resolve ${headers} if they come from a propertyPlaceholders

> Key: CAMEL-15087
> URL: https://issues.apache.org/jira/browse/CAMEL-15087
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 3.1.0, 3.2.0, 3.3.0
> Reporter: Andreu Font Bardolet
> Priority: Major
> Fix For: 3.4.0
>
>
> From camel 3.1 and up, I have detected that <doD/> doesn't resolve variables
> in propertyPlaceholders.
> For example:
> if i have an etc/uri.properties with:
> {{example=http://${headers.url}}}
>
>
>
> And in camel Context xml:
>
> ...
>
> <camelContext id="example"
> xmlns="http://camel.apache.org/schema/spring";>\{{}}
> <propertyPlaceholder id="myProperties"
> location="classpath:etc/uri.properties"/>
> <route id="test">
> <from uri="timer:hello?period=3000"/>
> <setHeader name="url"><constant>www.google.es</constant></setHeader>
> <log message="{{example}}"/>
> <!-- It logs: [http://www.google.es/] -->
> <toD uri="{{example}}"/>
> <!-- It resolves: [http://$|http://%24/]{headers.url}
> instead of [http://www.google.es/] -->
> {{ </route>}}
> {{</camelContext>}}
>
>
> {{But if i do a kind of a workarround like this, it works:}}
> {{...}}
> {{<camelContext id="example"
> xmlns="http://camel.apache.org/schema/spring";>}}{{}}
> <propertyPlaceholder id="myProperties"
> location="classpath:etc/uri.properties"/>
> <route id="test">
> <from uri="timer:hello?period=3000"/>
> <setHeader name="url"><constant>www.google.es</constant></setHeader>
> <setHeader
> name="workarround"><simple>{{{{example}}}}</simple></setHeader>
> <toD uri="${headers.workarround}"/>
> <!-- It resolves: [http://www.google.es|http://www.google.es/] -->
> {{ </route>}}
> {{</camelContext>}}
>
