screen widget set

[Chris Howe <cj...@yahoo.com>]

sorry if this got sent twice...i think the list filters messages with
<> in the subject line so I'm resending...anyway

Is it possible to accomplish something like the following (obviously by
a different means, because this way doesn't work), in a screen widget
definition

<set field="placement" value="4" type="Integer"/>
<set field="liveGrids[${placement}]" from-field="lg"/>

If not, would it be difficult/advisable to add such functionality to
the screen widget?

I think this fuction is already there.

In MethodContext.java:
    /** Gets the named value from the environment. Supports the
"." (dot) syntax to access Map members and the
     * "[]" (bracket) syntax to access List entries. This value is
expanded, supporting the insertion of other 
     * environment values using the "${}" notation.
     * 
     * @param key The name of the environment value to get. Can contain
"." and "[]" syntax elements as described above.
     * @return The environment value if found, otherwise null. 
     */
    public Object getEnv(String key) {
        String ekey = this.expandString(key);
        FlexibleMapAccessor fma = new FlexibleMapAccessor(ekey);
        return this.getEnv(fma);
    }
    public Object getEnv(FlexibleMapAccessor fma) {
        return fma.get(this.env);
    }
