[jboss-user] [JBoss Seam] - Problem with editing entity if it uses @EmbeddedId

[pczekaj]

I'm having problems with editing entity with @EmbeddedId. On page I've placed inputText element for every PK field, for example:
<h:inputText id="id_nr" value="#{uscModpskr.id.nr}" required="true"/>
I can see in inputText proper values fetched from database but when I click h:commandButton I'm getting 5 times Conversion error occurred message. My PK contains 5 fields: 2 strings, 2 ints, one char field.
