> According to [] the
struts.devMode setting can be read from environment strings or system properties. This works
correctly when setting from an environment string - for example:
> {{<constant name="struts.devMode" value="${env.STRUTS_DEV_MODE:false}"/>}}
> However it does not work for system properties, such as setting "-DstrutsDevMode=true"
as a system property and this in struts.xml:
> {{<constant name="struts.devMode" value="${strutsDevMode:false}"/>}}
> Having dug through the source I found that this is to do with the way the value substitutor
is configured, and that using ":-" instead of ":" as the separator string when using system
properties will work:
> {{<constant name="struts.devMode" value="${strutsDevMode:-false}"/>}}
