Question on Gbean attributes and serialisation

[Manu George]

Hi,
        I saw that in some GBeans Maps and various other structures are defined as attributes. Suppose I have a GBean with a map as an attribute how do i programmatically inject values for the attributes? Also if i want to change the attribute values i.e add more elements to the Map at runtime, how do I go about it? Will this attribute entry be then made in the config.xml as the config.ser does not change after deployment?   

Regards
Manu
