Regarding the variable names in the VOs.

Hi all, 

I am came across a bug which was caused because of using underscore in the variable name in the VO. 

 @Column(name = "concurrent_connections")
    Integer concurrent_connections;

because of this the call to update dose not update the VO and if the API is used only with this parameter the API server throws an error.

but if i change it to 


    @Column(name = "concurrent_connections")
    Integer concurrentConnections;

(remove the underscore)  it works. 

Dose any one know why this dependency is there. 

Regards,
Bharat.

AFAIK, The @Colume should be same to the column in database.
The variable concurrentConnections/concurrent_connections should be same to
the responding *DaoImpl.java

You can read Alex's tutorial regarding this:
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Data+Access+Layer
VO fieldname and its getter/setter method have to follow java convention.
