Import all build files in a directory - phing - phing

Question

I need to include all xml files inside a directory (I dont know the name, and count of files) in my current build.xml using ImportTask.
This is my build.xml file:
<?xml version="1.0" encoding="utf-8"?>
<project name="New Project" basedir="." default="myimport">
<target name="myimport" description="dummy to import other build files">
<if>
<isset property="file" />
<then>
<echo msg="Importing ${file}" />
<import file="${file}" />
</then>
</if>
</target>
<if>
<not>
<isset property="dummy.property" />
</not>
<then>
<echo msg="Now include all files in ./dev/build directory" />
<property name="dummy.property" value="true" />
<foreach param="msg" absparam="file" target="myimport">
<fileset dir="./dev/build/">
<include name="*.xml"/>
</fileset>
</foreach>
</then>
</if>
</project>
and an example file in target directory:
<?xml version="1.0" encoding="utf-8"?>
<project name="test" basedir="." default="dummy">
<target name="dummy" description="Dummy task">
<echo msg="Dummy task, just for test" />
</target>
<echo msg="Imported!" />
</project>
when I run phing -l the result is:
Buildfile: /home/f0rud/workspace/s/build.xml
[echo] Now include all files in ./dev/build directory
[foreach] Calling Buildfile '/home/f0rud/workspace/s/build.xml' with target 'myimport'
New Project > myimport:
[echo] Importing ./dev/build/test.xml
[echo] Imported!
Default target:
----------------------------------------------------------------------------
myimport dummy to import other build files
Main targets:
----------------------------------------------------------------------------
myimport dummy to import other build files
But there is no dummy (or test.dummy) target, why?
Note : There is a funny bug, if I remove the if part, I get Maximum function nesting level of '100' reached, aborting! error but thats not my problem (the if solve that problem.)

The problem is import work on global context.
When I call it inside a target, its not available in global context.
So I've written a simple Phing task to load all files of a fileset like so:
class ImportDirTask extends Task {
/** Array of filesets */
private $filesets = array();
/**
* Nested creator, adds a set of files (nested fileset attribute).
*/
function createFileSet() {
$num = array_push($this->filesets, new FileSet());
return $this->filesets[$num-1];
}
/**
* Parse a Phing build file and copy the properties, tasks, data types and
* targets it defines into the current project.
*
* #return void
*/
public function main () {
// filesets
foreach ($this->filesets as $fs) {
$ds = $fs->getDirectoryScanner($this->project);
$srcFiles = $ds->getIncludedFiles();
$srcDirs = $ds->getIncludedDirectories();
foreach ($srcFiles as $f)
{
$task = new ImportTask();
$task->setProject($this->project);
$task->init();
$task->setFile($this->file = $fs->getDir($this->project) . FileSystem::getFileSystem()->getSeparator() . $f);
$task->main();
}
}
} //end main
} //end ImportDirTask
It just work.
