I must apologise, the code for the SelectTag class I last posted was so wrong, it
wasn't funny. :(
Please ignore this terrible piece of code, I'll post a new, properly tested *blush*
version ASAP.

What I meant was that in the html:select tag ignore the "value" parameter.
Do not use the html:options but rather iterate through all of your possible
values and print out the html for option yourself. Then you can specify
which options are selected just as you would in normal html.

You mean to set the option label as selected? eg. '**Option**' to symbolise
selected and 'Option' as unselected. This is a pretty messy solution, but
it may
have to do. I will see if I can modify the source code for a more elegant
result,
allowing for time constraints.

Paul.

I had the same problem on a previous project. I looked at the source code
and currently you can specify only one value. A workaround is to check the
values yourself and set the selected option on the options. Alternatively
you can get the modify the source. If you do this, I hope you can post your
solution back to this list.

JC

Subject: pre-selecting multiple selects
Hi all,
I've written an input form that uses a multiple <html:select>.
The user selects the options they want and these options are
subsequently inserted into the database.
The problem is, that due to an apparent limitation of the html:select
"value" property, if I want to use it to update the database,
that is, I want the user to both be able to de-select existing
selections as well as select new ones, I don't seem to be able to.
This is due to the fact that the "value" field can only take a single
value! That is, I can set the value to "-1", so that each pre-selected
field is set to -1, but if these are re-selected I have no way of
telling which record was re-selected! And if it was de-selected I can't
tell which record I should delete!
I want to be able to pass a Collection object bean to the value field
instead,
so that all values in the Collection object are pre-selected so that these
values are also meaningful when passed back to my Action (or not).
I would love some feedback from anyone that may have a work-around for this,
if not it is a serious limitation of the html:select tag.
regards,
Paul
