]
Peter J Ford updated WW-4928:
-----------------------------
Description:
According to [http://struts.apache.org/core-developers/constant-configuration.html] 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}"/>}}
