message routing with choice option within choice option

[lyfe]

I'm trying to get the below code to work:

from().choice().when().method().process().to().when().method().process().to().end();

I want to evaluate against the second "method" depending on the output from the first "to".  If the second "method" evalutes to false, I want to return the output from the first "to".

When I run the code, it only evaluates against the first "method" and never hits the second "method".

choice

  when

  when

  otherwise

is just like a regular java

if

else if

else is

else

So no surprise that if the first when is evaluated to true then its executed. And if its evaluated to false then the next when is evaluated and so on.

What do you use in the when as predicate? Maybe its being evaluated to true all the time.

I'm using a bean.  I take the exchange as an xml string and set variables while I parse it.  Then I pass back a true or false based on what I want to know.

I'm a little confused on your last sentence: Maybe its being evaluated to true all the time.  Can you elaborate?

From my testing, all when statements (except the one in question) is evaluating correctly.  I actually have 5 when statements.  4 of the 5 when statement's predicates are being evaluated against tags that only appear in a request.  The last when statement's predicate is being evaluated against tags that only appear in a response.

Also, for additional clarity, I want to achieve:

if {...}

else if {... if {...}}

else if {...}

else {...}

..based on what is returned from first if else, I want to execute the embedded if.

I apologize in advance for rehashing if you understood the situation.

You can do nested choices but then remember to end it with an end(). Its however often most easier to use direct to link to another route with has the nested route

from foo

  choice

     when bar to bar

     when baz to baz

  end

from bar

  choice

    when a

    when b

worked beautifully...thanks
