>                 Key: CAMEL-18626
>                 URL: https://issues.apache.org/jira/browse/CAMEL-18626
>             Project: Camel
>          Issue Type: Improvement
>          Components: camel-core
>    Affects Versions: 3.19.0
>            Reporter: Raymond
>            Priority: Minor
>             Fix For: 3.20.0

> I would like to set the ExchangePattern dynamically with a routetemplate like this:
> {code:java}
> routeTemplate("setPattern")
>     .templateParameter("in")
>     .templateParameter("out")
>     .templateParameter("exchangePattern")
>     .from("{{in}}")
>         .setExchangePattern("{{myExchangePattern}}")
>         .to("{{out}}");{code}
> This is currently not possible as template parameters expect only Strings. I tried to work around it. For example:
>  
> {code:java}
> .setExchangePattern("ExchangePattern.valueOf({{myExchangePattern}})")
> //or
> .setProperty("ExchangePattern").simple("${exchange.setPattern('{{ExchangePattern}}')}")
>  
> {code}
> But they don't work because the \{{parameter}} are interpolated too late in the process. For now, I used I set a property and use processor to set the ExchangePattern.
