Currently, when I import existing maven project with Seam Transactions, the editor complains about incorrect tag in beans.xml file. The transactions implementation is currently in the seam-persistence module (http://sfwk.org/Seam3/PersistenceModule). I imported a project from Remoting module which uses this transaction management (by including the persistence's jars. It's the Validation example (https://github.com/seam/remoting/tree/master/examples/validation).

After importing these project into Eclipse it complains about the following lines in the beans.xml:

<p:SeSynchronizations>
<s:modifies/>
</p:SeSynchronizations>

The error message is simply something like "Invalid content was found starting with element 'p:SeSynchronizations' ... "

The whole beans.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="urn:java:org.jboss.seam.persistence.transaction"
xmlns:s="urn:java:ee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">

<p:SeSynchronizations>
<s:modifies/>
</p:SeSynchronizations>

<interceptors>
<class>org.jboss.seam.persistence.transaction.TransactionInterceptor</class>
</interceptors>

</beans>

Note that there was a discussion about moving the transaction management into another module. Ask module lead about this.
