rte as subscript
can we access memebers of an array like
<form:select property="array[i]"> in a for loop... It
works if I use constants but not expressions..
property="array[0]" is fine but not array[i] or
array[<%=i>] for the property attribute of
form:select. Any clues???

I tried using it, but I think when it is converted
into html it goes out like <select name="array[0]">
but when we posted your code tries to look for
array%5b0%5d ( [ and ] ) being encoded. Is this what
is expected????

The property accessor syntax in Struts 1.0 supports only constants as
array subscripts.
You might consider using some sort of runtime expression instead, to
dynamically calculate the property to be retrieved. Assume that "i" is
an integer variable, and you are inside a loop:
<form:select property='<%= "array[" + i + "]" %>'/>
