OneToOne could be null

swenu Nov 11, 2009 9:27 AM

Hi

i have a question about a OneToOne within an entity.

What i want is that this assignment is optional.
I solved it like this:

@OneToOne(optional = true)
 @JoinColumn(name = "company", nullable=true)

It doesn't work when i want to save a null assignment!

Hi Sven,

I think you have to play around with the properties of the "@OneToOne" annotation. First I would try something like this:

@OneToOne (cascade = CascadeType.ALL)

Hope this helps

Hi Wolfgang

This is a suggestion box. The user could not change anything of the company. Only selection.

Hi,

so you want to just change the relationship between two entities without changing any of them? Please post the snippet of code where you manage this relationship. Did you make sure that both entities are under control of the entity manager (not "detached")?

Did you declare some "transient" variable? The original exception talks about it.

Hope this helps

Hi Wolfgang

Sorry long time ago i've posted!
I have a person which i can edit and this person could be assigend to a compnay.
But this assignment is optional!

Here's the code for the selection

<s:decorate id="companyField" template="layout/edit.xhtml">
 <ui:define name="label">Firma</ui:define>
 <h:panelGrid columns="3" border="0" cellpadding="0" cellspacing="0">
 <h:inputText id="companySelection" converter="#{companyConverter}" value="#{personHome.instance.company}" required="false"/>
 <h:graphicImage value="img/arrow.png"
 onclick="#{rich:element('companySelection')}.value = '';#{rich:component('suggestion')}.callSuggestion(true)"
 alt="call company list" />
 <a4j:outputPanel id="companyEdit">
 <s:link view="/companyList.xhtml" id="companyLink"
 value="#{personHome.instance.company.name} bearbeiten" propagation="none"
 rendered="#{personHome.instance.company.id > 0}">
 <f:param name="companyId" value="#{personHome.instance.company.id}" />
 </s:link>
 </a4j:outputPanel>
 <rich:suggestionbox id="suggestion" for="companySelection" suggestionAction="#{companyBean.autocomplete}" var="_c" ajaxSingle="true">
 <a4j:support event="onselect" reRender="companyEdit,companyAddress">
 <f:param name="companyId" value="#{_c.id}" />
 <f:param name="company" value="#{_c}" />
 </a4j:support>
 <h:column>
 #{_c}
 </h:column>
 </rich:suggestionbox>
 </h:panelGrid>
 </s:decorate>

Yes i got @Transient annotation used within person.java

Thanks for you advice

wolfgangknauf Nov 20, 2009 7:04 AM (in response to swenu)

Hi,

probably "@Transient" on a relation field does not work. Try to remove it.
To prevent unnecessary persisting of the entity, you might set the "cascade" attribute to e.g. "don't cascade persist calls".

Hope this helps
