dynamic generation of select fields problem

2003-12-05 Thread Ruben Pardo 
Hi everybody!

  This is my problem, i've to generate a variable
quantity of select fields. The solution i thougth was
a map backed form, that dynamically generate the names
of this fields with JSTL, something like this:

c:forEach  items=${sessionScope} var =farmacia
varStatus=st
 .
  html-el:select property=value(campos${st.count})
   ..
   ..
  /html:select


/c:forEach 

but qhen i try to run this, i've got an
NullPointerException saying me that no getter for
property value(campo1) ...

I don't know what could be the problem, or how i can
solve in other way.

Thanks a lot and any type of help could be aprecciated.

Ruben,

I guess that you can't access a property using a sintax of function in:

html-el:select property=value(campos${st.count})

Maybe you need to use the sintax of array:

html-el:select property=value[campos${st.count}]

Certo?
