Spring web flow execution is not always working

I have configured beans in the webmvc-config.xml file, and have those beans defined in my flow.xml, as follows:
flow executes correctly only the transition on="success" to="verifyInjuredWorkerHomeAddressAction". It will not execute the "injuredWorkerEntryNextPage" tag, when that condition has been met. Anyone have any ideas?

webmvc-config.xml file:
<bean id="injuredWorkerEntryValidator" class="com.summitholdings.noi.web.intake.InjuredWo rkerEntryValidator">
<property name="idNumberTypeRegistry" ref="idNumberTypeRegistry" />
<property name="injuredWorkerEntryValidatorAction" ref="injuredWorkerEntryValidatorAction" />
</bean>
<bean id="injuredWorkerEntryValidatorAction" class="com.summitholdings.noi.web.intake.InjuredWo rkerEntryValidatorAction" />

flow.xml:

<view-state id="injuredWorkerEntryNextPage" view="internalIntake/injuredWorkerEntryNextPage" model="injuredWorkerEntry">
<on-render>
<evaluate expression="injuredWorkerEntry.calculateDisability Date(submission)" />
</on-render>
<transition on="next" to="injuredWorkerEntryValidatorAction" />
<transition on="previous" to="injuredWorkerEntry" validate="false" />
</view-state>

<action-state id="injuredWorkerNextPageErrorState">
<evaluate expression="injuredWorkerEntryValidatorAction.setE rrorsExistMessage(flowRequestContext)" />
<transition to="injuredWorkerEntryNextPage" />
</action-state>


<action-state id="injuredWorkerEntryValidatorAction">
<evaluate expression="injuredWorkerEntryValidatorAction.vali date()" />
<transition on="success" to="verifyInjuredWorkerHomeAddressAction" />
<transition to="injuredWorkerNextPageErrorState" />
</action-state>
