Hi,

I'm trying to configure a remember-me setting in xml using spring expression language.
We frequently modify our spring configuration from a properties file by using spel to grab properties from the file, and then using a different properties file in a different deployment.

So in some properties files there would be a key named ssl with a value of true, and in others the key would have a value of false.

The config file looks something like this:

<util:properties id="appProperties" location="classpath:application.properties"/>

<http use-expressions="true" auto-config="true" create-session="stateless">
<!-- more things go here -->
<remember-me token-validity-seconds="3600" key="smartStepsKey" use-secure-cookie="#{ appProperties['ssl'] }" />
</http>



With most other areas of spring this works fine, but when I try to manipulate the remember-me element that way, I get an exception (stack trace below).

Is this something I should expect to be able to do? If not, is there a simple workaround that I've overlooked?

Cheers,

Sean
