Question

Hello All,
        I'm new to BSP.
I have a small querry.
I have a input field.
beside this a push button.
if i enter a value in the input field and press the push button, i need to capture the value from the input field and pass it to a variable contained in a class.
i'm attaching the layout code here.
but i'm not knowing what to write in the event(on input processing)

HI BSPian,
    htmlb:inputField value = "<%= v_value %>"
                     id = "gv_var"
                     required = "true"
                     size = "10"
                     type = "STRING"
                     maxlength = "10"
                     design = "standard" />
Here u mean to say that v_value must be one more field type string. is it so ?
But i want to see the value in the same input field
id ="gv_var". i.e if i enter the value "BSPian" in the input field and press "submit" the internal processing will be done as told by u and after that ,on the screen i want to keep that value till i end that session.
i passed a variable v_value in the inputfield value but it's not working ..
regards,
deepu.
