Wendy,
You have been very helpful. This is my first STRUTS app and I seem to
stumble the most on getting these tags to work. I have not found any real
documentation examples to help me. At any rate, I tried to use the options
collection tag and I had no success. It was one error after another. I
finally got the lists to display as a drop down using the JSTL tag forEach.
This is what my code looked like when I was trying to use the options
collection tag:
<html-el:select name="reviewRecordForm" property="csci.options">
<html-el:options collection="${reviewRecordForm.map.csci}"
property="optionId" labelProperty="optionLabel"/>
</html-el:select>
After reading what you wrote, I think I should try the following to get it
to work:
<html-el:select name="reviewRecordForm" property="csci">
<html-el:options
collection="${reviewRecordForm.map.csci.options}"property="optionId"
labelProperty="optionLabel"/>
</html-el:select>
csci is another property in my form bean which is the same type as
baseline..... In the properties field of the select tag I used the
collection instead of the actual form bean property. I think maybe this was
my problem. I am going to try it and see what happens.
Do you think I am on the right track??
Thanks for your help,
Natalie

The entire contents of the drop down is a different thing than the single
item from that list that the user has selected. I don't store the lists of
items in my Form bean, but YMMV.
You don't have to do the iteration with c:forEach, the select tag will do it
for you.
Here's one of mine:
<html-el:select property="purpose">
<html-el:options collection="reminderPurposes" property="key"
labelProperty="value"/>
</html-el:select>
Where 'reminderPurposes' is a Collection sitting in Application scope.
If I wanted to "pre-select" a certain item, I might (in the Action's execute
method) do:
( (DynaActionForm) form ).set( "purpose", "GI" );
Instead, I just do this:
BeanUtils.copyProperties( dvForm, contact );
and since the DTO and the form both have a 'purpose' property, the value
gets copied from the DTO (contact in this case) to the form.
You ask what you're supposed to set 'baseline' to. I thought you were
originally asking how to pre-select a certain value before the form is
displayed for the first time. If you don't have a value in mind, then don't
set it to anything.
However, most of the problem seems to be that you're working too hard...
Struts handles most of this, the iteration over a Collection, pre-selecting
the right item, magically behind the scenes, and you don't have to do
anything.
