Heck of a thing to find first day back from vacation:

A colleague and I are both running the same version of ant, version =
1.5Beta3.

We are running ant over the same scripts.

Script A makes an <ant> call to script B. =20

Script A calls the following target: (located in script B):

    <target name=3D"sportsbean">
        <antcall target=3D"checkout">
            <param name=3D"projectroot" value=3D"${root}/sportsbean"/>
            <param name=3D"ST.proj" value =3D "SportsBean" />
            <param name=3D"ST.view" value =3D "${sportsbean.vers}" />
            <param name=3D"ST.folder" value =3D "/sportsbean" />
            <param name=3D"ST.label" value =3D "${sportsbean.lbl}" />

        </antcall>
...
    </target>

Previously defined in script B are these properties:
    <property name=3D"sportsbean.vers" value=3D"Version 5.1"/>
    <property name=3D"sportsbean.lbl" value=3D""/>

The definition of the "checkout" target (located in script B) is as =
follows:

    <target name=3D"checkout">
        <mkdir dir=3D"${projectroot}"/>
        <delete dir=3D"${projectroot}"/>
        <echo message=3D"Checking out from:"/>
        <echo message=3D"  Project: ${ST.proj}"/>
        <echo message=3D"  View: ${ST.view}"/>
        <echo message=3D"  Folder: ${ST.folder}"/>
        <echo message=3D"  Label: ${ST.label}"/>
        <stcheckout servername=3D"${ST.server}"
            serverport=3D"${ST.port}"
            projectname=3D"${ST.proj}"
            viewname=3D"${ST.view}"
            username=3D"${ST.user}"
            password=3D"${ST.pswd}"
            rootstarteamfolder=3D"${ST.folder}"
            rootlocalfolder=3D"${projectroot}"
            excludes=3D"*.war"
            forced=3D"yes"
            label=3D"${ST.label}"
      />
    </target>

Never mind the optional <stcheckout> task which is probably unfamiliar.  =
The problem I am grappling with is far more troubling and puzzling =
because it is merely a question of property definition:

Notice the five echo calls.

In my colleague's run of this script, the following output is produced =
by these calls.  This is the output I would expect.

Checking out from:  =20
  Project: SportsBean
  View: Version 5.1 =20
  Folder: /sportsbean
  Label:            =20

In my run of the same script, this is the output of the same script, run =
with the same parameters.

Checking out from:
  Project: SportsBean
  View:=20
  Folder: /sportsbean
  Label:=20

The key difference is the blank content of the ${ST.view} parameter.
Again, to reiterate: there is no difference between the way my colleague =
is running this script and the way I am.  Nothing in either script, the =
command line, or any property file defines the the ${sportsbean.vers} =
property (which feeds the ${ST.view} param) other than the single line =
in script B where it is defined.

I am completely at a loss to explain these results.  It seems as though =
my run of the scripts is
causing the ${sportsbean.vers} property to be "forgotten" across the =
<antcall> in my case but not in my colleague's case.

Does anyone know of any bugs in ant version 1.5Beta3 that could account =
for these results, or can anyone think of something that I am =
overlooking, which could cause them?
