CruiseControl - svn modificationset doesn't work

Apache

Hello,

in my cruisecontrol config.xml I defined a svn modificationset. if somebody commits new data to the svn an ant-build should start after 30 seconds. but this doesn't happen.
only if a sheduled or forced build is started and was successful, cruisecontrol checkes for modification and a new build will start after 30 seconds.

here my modificationset task:

<br />
<svn RepositoryLocation="path/myProject" username="user" password="XXXX" /><br />
<br />

thanks
