I'm having such piece of code:

<rich:column rendered="#{dictMgr.isSubDictionary()}">
    <h:selectOneMenu value="#{x.precedent.id}">
        <f:selectItem itemLabel="#{messages.combo_choose}" itemValue="" />
        <f:selectItems value="#{dictMgr.selectPrecednetValues}" />
    </h:selectOneMenu>
</rich:column>

which displays values of a dictionary, this exact column displays precedent if
dictionary is hierarchical, based on result isSubDictionary() method. But when submitting
form with above code I get error when current dictionary doesn't have precedent field,
which is true in that case. I used this code with Seam 2.0.6.GA and RichFaces 3.1.6.GA
and everything worked fine, but now it doesn't.
Curious thing about it is when instead x.precedent.id I use a method of some kind
everything works fine, how about that?

Appreciate any help,
Maciej
