Can I create a flag variable in a entity-home maded in a com

[srpantano]

I need to create a flag variable (parameter) for a entity-home object created by component.xml, is it possible?

You can extend the EntityHome class, put your variable name there and reference your newly created class in components.xml using something like

<component name="name" class="a.b.c.ExtendedEntityHome">
 <property name="someFlagVariable">someValue</property>
</component>

or you could even use the Namespace feature part of Seam. The documentation have more info on this.
