I agree that the code you supplied is not the best (or least complex) way to
solve this. Using scriptlets is what I want to avoid (but what I also
resorted to). However, the code that you gave does not solve the problem.
I need to compare the "loop variable with a property on my action".
Creating a collection to hold the numbers 1 to 31 is also a round about way
to achieve something very simple.
I am not using the select control because, as far as I can tell, it does not
allow you to use it in forms that are not laid out in the simple single
column design (is this correct?). The control header creates a new row in a
table (supplied by the <ww:form> element) with two <td>'s. My design
requires a more complex form layout. It requires that two controls appear
in the same row adjacent to each other. Or is there a way to get the Select
tag to work in these situations?
What would be handy here is functionality similar to the JSTL iterator tag
that allows you to also specify a start value and an end value. Maybe it
could put the index value on the stack so that you can easily use it in
comparisons with properties on the Action.
