unselect slave component by default

[Satyanarayana Jampa]

Hi,
                I have a custom slave component, during installation in the 
"Assign slaves and clients" screen, it is being checked by default.
                How can I make it unchecked by default.

                I  have set the cardinality if the slave component in 
metainfo.xml to 0+

Thanks,
Satya.
