I have the following defined on my struts_config.xml:
<form-bean name="telnetForm"
type="org.apache.struts.action.DynaActionForm">
<form-property name="ipaddress1" type="java.lang.String" />
<form-property name="ipaddress2" type="java.lang.String" />
<form-property name="ipaddress3" type="java.lang.String" />
<form-property name="ipaddress4" type="java.lang.String" />
<form-property name="netmask1" type="java.lang.String" />
<form-property name="netmask2" type="java.lang.String" />
<form-property name="netmask3" type="java.lang.String" />
<form-property name="netmask4" type="java.lang.String" />
<form-property name="netmaskbits" type="java.lang.Integer" />
<form-property name="subnet1" type="java.lang.String" />
<form-property name="subnet2" type="java.lang.String" />
<form-property name="subnet3" type="java.lang.String" />
<form-property name="subnet4" type="java.lang.String" />
<form-property name="seedby" type="java.lang.String" />
<form-property name="row" type="java.lang.String" />
<form-property name="mode" type="java.lang.String" />
<form-property name="SELECTED" type="java.lang.String[]" />
</form-bean>
and
<action name="telnetForm"
type="com.micromuse.precision.disco.action.TelnetAction"
scope="session" path="/telnet">
<forward name="success" path="/pages/disco/show_telnet_pwds.jsp"
/>
<forward name="failure" path="/pages/disco/show_telnet_pwds.jsp"
/>
<forward name="telnet" path="/pages/disco/telnet_password.jsp" />
<forward name="advanced"
path="/pages/disco/telnet_password_advanced.jsp" />
</action>
When I had the scope set to request this worked fine, but I need it set
to session...
When I used the tag: <html:checkbox name="telnetForm"
property="SELECTED" value="<%=value%>" /> and the form's scope is for
session I get the error:

However, that doesn't happen when the scope is set to 'request'... More
puzzling, is that this only seems to happens with checkboxes, but not
<html:text>... Does anybody know why this is so?
