Hi,I use spring web flow 2 with hibernate annotations. Is there possible that in my jsp using form tags to bind a whole class? I am asking this, because when I generated my entity classes from SQL Server 2008 using Intellij it autogenerated also my @ManyToOne column (it's about 2 tables: one named Leader-with idLeader,name..and so on and another named Phd in wich i have idLeader refered. When I generated my tables with hibernate annotations, in my Phd class intellij put also my @ManyToOne columnm (PhdEntity has now beside the idLeader property, another one refering to Leader class with getter and setter). All was good until I tried to run my application and gaved me the error that i must put insertable = false, updatable = false at idLeader column. Having that done, my application worked perfectly until I had to insert the referenced column idLeader wich doesn't work because I have the insertable = false, updatable = false. In that case it is rationable to insert the class Leader instead of the id(beacause I have the column generated). So in my jsp i have all the ${leaders} in a form:select with the path='Leader' but I can't fix this because it gives me the error that it can't bind String to Leader.class (even if i add a PropertyEditorRegistrar: propertyEditorRegistry.registerCustomEditor(Leader Entity.class,new ClassEditor()); It is possible to bind a whole Leader.class or I have to delete that autogenerated column and let only my idLeader in PhdEntity class? Thanks in advance
