I was able to get it to work by invoking a macrodef instead of a target.
<?xml version="1.0" ?>
<project name="build" basedir="." default="test">
<target name="test">
<script language="javascript">
<![CDATA[
project = self.getProject();
echo = project.createTask("echo");
echoVal = project.createTask("echoval");
echo.setMessage("foo");
echo.perform();
echoVal.setDynamicAttribute("value", "foo");
echoVal.perform();
echo.setMessage("bar");
echo.perform();
echoVal.setDynamicAttribute("value", "bar");
echoVal.perform();
]]>
</script>
</target>
<macrodef name="echoval">
<attribute name="value"/>
<sequential>
<echo>@{value}</echo>
</sequential>
</macrodef>
</project>
This produces the following result.
test:
[echo] foo
[echo] foo
[echo] bar
[echo] bar
BUILD SUCCESSFUL

Subject: Re: Problem with script task and properties
Hi Scot,
Thanks a lot for your reply.
Yes, I've already known that behavior of "Variable" Task.
What I would like to know is the proper coding in Script Task by using
Javascript.
I wonder my conding doesn't make sense ?
