Description

I would like to set the ExchangePattern dynamically with a routetemplate like this:

routeTemplate("setPattern")
    .templateParameter("in")
    .templateParameter("out")
    .templateParameter("exchangePattern")
    .from("{{in}}")
        .setExchangePattern("{{myExchangePattern}}")
        .to("{{out}}");

This is currently not possible as template parameters expect only Strings. I tried to work around it. For example:

 

.setExchangePattern("ExchangePattern.valueOf({{myExchangePattern}})")

//or
.setProperty("ExchangePattern").simple("${exchange.setPattern('{{ExchangePattern}}')}")
 

But they don't work because the parameter are interpolated too late in the process. For now, I set a property and use processor to set the ExchangePattern.
