references and concat

Hello,

I encountered one problem concerning resolution and concat of strings. Let 
me illustrate it with a small example (I omit the "#include..." 
statements) consisting of 3 components (file1.sf, file2.sf, file3.sf):

file1.sf:

file1 extends {
 string1 "string1 in file1";
 string2 "string2 in file1";
 string3 (string1 ++ " and " ++ string2);
}

file3.sf

sfConfig extends Compound {
 a extends file1;
}

This works fine, "sfParse file3.sf" yields:

sfCodeBase "default";
sfClass "org.smartfrog.sfcore.compound.CompoundImpl";
a extends  {
	string1 "string1 in file1";
	string2 "string2 in file1";
	string3 "string1 in file1 and string2 in file1";
}

SFParse: SUCCESSFUL

Now I introduce a component file2:

file2 extends {
 string4 file1:string2;
}

I change file3 to:

sfConfig extends Compound {
 a extends file2;
}

This works also fine, "sfParse file3.sf" yields:

Parser - SmartFrog 3.02.002_beta

sfCodeBase "default";
sfClass "org.smartfrog.sfcore.compound.CompoundImpl";
a extends  {
	string4 "string2 in file1";
}

SFParse: SUCCESSFUL

Now I change file2 to reference the concateneted string from file1:

file2 extends {
 string4 file1:string3;
}

This doesn't work, "sfParse file3.sf" yields:

Parser - SmartFrog 3.02.002_beta
(C) Copyright 1998-2004 Hewlett-Packard Development Company, LP
 
ERROR 'file3.sf': 
SmartFrogCompileResolutionException:: Unresolved Reference, data: [string1 
in: HERE sfConfig:a:string4, string2 in: HERE sfConfig:a:string4], source: 
HERE sfConfig, resolutionPhase: link

Error detected. Check report.
SFParse: FAILED

Why doesn't this work ?

Thanks,
Andreas
