Indirect property lookup failing.

[George Storm <gs...@divxcorp.com>]

I am experimenting with ways to change the case of the text I am passing to
a target. In the following test I have created a small table which I am
accessing indirectly.

>From my primary call (ant-test) I call (target1) which creates a compound
string which will be used to lookup my replacement string (target2) which
will be used by my final target (target3).

My problem is that in target2 instead of it returning the contents of my
property it is returning the name of the property.

Your assistance would be appreciated.

Thanks,

Actual script:

<project name = "AntTest3" default = "lookup-test" basedir = ".">

    <property name = "txt.l.dosomething" value = "dosomething"/>
    <property name = "txt.t.dosomething" value = "Dosomething"/>
    <property name = "txt.u.dosomething" value = "DOSOMETHING"/>

    <target name = " lookup-test">
        <echo message = "txt.l.dosomething: ${txt.l.dosomething}"/>
        <echo message = "text.t.dosomething: ${txt.t.dosomething}"/>
        <echo message = "txt.u.dosomething: ${txt.u.dosomething}"/>

        <antcall target = "target1">
            <param name = "action" value = "dosomething"/>
        </antcall>
    </target>

    <target name = "target1">
        <echo message = "action: ${action}"/>
        <antcall target = "target2">
            <param name = "txt.action" value = "txt.t.${action}"/>
        </antcall>
    </target>

    <target name = "target2">
        <echo message = "txt.action: ${txt.action}"/>
        <antcall target = "target3">
            <param name = "do.action" value = "${txt.action}"/>
        </antcall>
    </target>

    <target name = "target3">
        <echo message = "do.action: ${do.action}"/>
    </target>

</project>

----------------

Result:

lookup-test:
     [echo] txt.l.dosomething: dosomething
     [echo] text.t.dosomething: Dosomething
     [echo] txt.u.dosomething: DOSOMETHING

target1:
     [echo] action: dosomething

target2:
     [echo] txt.action: txt.t.dosomething

target3:
     [echo] do.action: txt.t.dosomething

Hi George

yes properties are by design immutable (once set cannot change)
I think you may want to look at implementing dynamic set capability with 
'variable'
http://ant-contrib.sourceforge.net/tasks/tasks/variable_task.html

Does this help?
