selectOneMenu: Value will not be set

I've got a dropdown menu, which gets the persons from our LDAP server. What I basically did was copying the SelectOneMenuDemo from the Demo files.

However, it's displaying all persons correctly in the dropdown, but it won't set the selected person to my data.manager.

This is the code from the demo:

<p:selectonemenu value="#{data.selectedPerson}" converter="ivy.ListItem">
<f:selectitem itemlabel="Select One" itemvalue=""/>
<f:selectitems value="#{data.persons}" var="it" itemvalue="#{it}" itemlabel="#{it.name}"></f:selectitems> <f:selectitems value="#{data.morePersons}" var="it" itemvalue="#{it}" itemlabel="#{it.name}"></f:selectitems> <f:selectitem itemvalue="#{data.onePerson}" itemlabel="#{data.onePerson.name}"></f:selectitem> </p:selectonemenu>

And this is what I wrote:

<p:selectonemenu id="manager" value="{data.manager}" converter="ivy.ListItem" style="width: 200px;"> <f:selectitems value="#{data.managers}" var="it" itemvalue="#{it}" itemlabel="#{it.cn}"></f:selectitems> </p:selectonemenu>

Is there something I've forgotten? This looks exactly the same to me. Do I have to do something when I submit? I've got a multiview HTML dialog.

Dynamic amount of fileuploads: file not uploading

I'd like to give the user the ability to choose the amount of attachments he'd like to provide. To do this I created a datatable with buttons to add and remove attachment-lines:

<p:dataTable id="attachments" var="attachment" value="#{data.attachments}">
    <p:column headerText="#{ivy.cms.co('/labels/vendor')}"><p:inputText value="#{attachment.vendor}" /></p:column>
    <p:column headerText="#{ivy.cms.co('/labels/description')}"><p:inputText value="#{attachment.description}" /></p:column>
    <p:column headerText="#{ivy.cms.co('/labels/amount')}"><p:inputText value="#{attachment.amount}" /></p:column>
    <p:column headerText="#{ivy.cms.co('/labels/attachment')}"><p:fileUpload value="#{attachment.file}" mode="simple" /></p:column>
    <p:column headerText=""><p:commandButton value="delete-row" update="attachments" action="#{logic.deleteAttachment(attachment)}" /><p:commandButton value="add-row"  update="attachments" action="#{logic.addAttachment()}" /> </p:column>
</p:dataTable>

The only problem is, that it seems to not upload the specified file. The submitted form is beeing processed by this script, the output of in.test beeing false:

for(Integer i = 0; i < in.attachments.size(); i++) {
    in.test = in.attachments.get(i).file.exists().toString();
}

The Simple-Fileupload-Demo works, so I guess it can't be a problem with my installation / computer. I just cleared all of the attachments and uploaded only one. So while this is a foor loop, it just iterates through 1 time. Data is stored in my own Data Class Attachment, containing 4 attributes (Vendor, Description, Amount and File).
