Hi All
Did you find an actual solution to the null value problem. I have hit
the problem, and I am about to embark on creating a custom converter to
deal with null values, but I am assuming that people have dealt with
this problem before.
To recap,
I have this jsf code:
<h:selectManyListbox id="housetypeSelect"
value="#{NewContact.houseTypesSelect}" size="5" >
<f:selectItems id="housetypeSelectItem"
value="#{NewContact.housetypes}" />
</h:selectManyListbox>
Which works perfectly when a item or more is selected, however if
nothing is selected then a conversion error occurs, for the component.
I presume this is a null value conversion error.
Thanks for any help,
James Salt

Does your converter handle the null case?
Are there more in-depth errors in the logs? stack traces?
