returns an String[] when is checked!

[Felipe Rodrigues <fe...@yahoo.com.br>]

Hi guys,

I'm using ActionContext.getContext().getParameters().get("checkboxName"); to
get a value from a checkbox in my jsp.
The problem here is, when its value is false, works fine, I got an String.
But when my checkbox is checked and I call this same method, I got a
String[] and as you know, if I cast from String[] to String I got an cast
exception.
Does somebody knows why I got this behavior?

Thanks,

Felipe

Try declaring a boolean setter in your Action with the checkbox name.

i.e.  

setCheckboxName( boolean val ) { this.checkboxName = val ; } 

and using that instead.

I'm not sure why you're trying to get the value from the
ActionContext.getParameters().  That will return the raw, globbed values of
the parameters, and they by nature are multi-valued, so a String[] is
expected. 
( it's possible for a query string to be someParam=a&someParam=b ).
