grails - GSP pass Array from controller and display in gsp by its index -

how can pass array controller gsp, , view index in gsp?

lets in controller:

string[] str= new string[2]; str[0]="a" str[1]="b"  render(view: "test_preview",model:[flag:str]) 

and in gsp, how can call let index [1] value "b" in gsp without looping possibly?

you can try this.

1. you pass full array view. , in view, following:

   ${flag[1]} 

2. or: pass specific value view. in controller:

   render(view: "test_preview",model:[flag:str[1]) 

   and in view:

   ${flag}
