Subject Re: Action inheritance and value automatic injection failure
Date Tue, 29 May 2012 14:16:45 GMT
I guess you're using Spring.

If you use Spring injection via an xml file, you must use inheritance:

    <bean id="baseAction" class="com....BaseAction" scope="prototype">
    </bean>

    <bean id="itemDetails" class="com....ItemDetails" scope="prototype"
depends-on="baseAction">
        <property name="itemId" ref="itemId"/>
    </bean>

    <bean id="saveItem" class="com....SaveItem" scope="prototype"
depends-on="baseAction,itemDetails">
    </bean>

Cheers,
J.
