RE: Passing variables for logic:iterate
I don't believe that is "smart" enough to know that
if the value for the offset or length attribute is not an integer then
attempt to "find" the named value in all scopes.
You can do something like this:
Or you could use Struts-EL which provides a JSTL like syntax.

RE: Passing variables for logic:iterate
1st, Thank you, I didn't realize the logic:Iterate tag had those two
properties, so you've indirectly saved me some effort.
2nd, After looking at the source code for the iterate tag, it looks like it
tries to look up those two values straight out of the pageContext. This
would imply to me, that it doesn't look up the property on the form as it
appears you want it to do. (i.e. if you do a
request.setParameter("pageOffset","5") in your Action Class) or use a
tag on your jsp page, it should work
correctly.
I think both ways are valid, but my gut is that the way you where going at
it is the way anybody unfamiliar with the tag would try to use it.
Perhaps this is a candidate for refactoring, I'd personally like a way to
choose either way. It just seems bad practice to have one field be sucked
from the bean, and two others be read from the page context (and it appears
to be a simple 2 line fix).

Ok, this is probably a dumb questio, but here it goes...
I am trying to iterate over a portion of a list. I have calculated the
portion (the offset and length) in my action. I have two entries in my
DynaValidatorForm:
And I am doing a myform.set("pageOffset", String.valueOf(myCalcOffset));
etc.
The iterate is:
It just plain doesn't work. If I substitute something like "5" for
pageOffset or pageLength, it works like a champ.
What am I missing? It's got to be something simple...
Thanks,
/greg

Damn! I hate being lazy. Thanks Mike for correcting my sub-par answer.
I should have looked at the source before responding.

You need to pass it Integer objects or put the actual values into the tag.
