Jelly XML -passing varaible from jelly to java

hi all,
I wanted ot know if it was possible to pass multiple comma seperated variables from jelly to java .
When i try to pass a single var it retains the type of object the var contains .
But when i try to pass multiple vars using a single var like consname="${alg2},${alg3}" ,the alg2 and alg3 vars are converted to string .

Please let me know how do i go about this.

Thanks,
Sayali
