hi there !, i was able to partially resolve that issue, you see, i am working in a java desktop application, this application has at least 28 or so entities, two were created by netbeans and the other ones I created them (mySql databse with innodb engine), so i had to code additional primitive variables to the 2 entities generated by netbeans (cliente and cartas) and had this error message:

}After i did that, the 'no persistance...' problem was solved but... i cant integrate my data properly... the 'producto' entity uses a composed PK defined in ProductoPK class, does this has something to view ???
As you can see, other properties such as:
@OneToMany(cascade = CascadeType.ALL, mappedBy = "rfcCliente")
    private Collection<Documento> documentoCollection;dont give any trouble... so, what shall i do ??
