<form:select> binding

thank you, this was a wrong copy/paste, it should be name instead.

The scenario is the user select an item from the drop down list, then submit the form. what I get is that drug.id is set to the selected value, but I also want drug.name to be set to the selected label, is that possible?

note *drug* in my comment is the command object.

u can use hidden filed in the <form:select>

>> u can use hidden filed in the <form:select>
could you please elaborate?

<form:select id="drug-id"
        path="drug.id">
        <form:option value="0" label="select drug name" />
        <form:options items="${drugs}" itemLabel="description" itemValue="id"/>
       <form:hidden name="drug-name" path="drug-name">
</form:select>

sorry try this  
<form:hidden name="drug-name" path="drug-description">

>  is that possible?

no it isn't. What you would do is just lookup the drug instance using the selected id
(or if you don't actually need the id the use name for itemValue

again sorry ...
<form:hidden id="drug-name" path="drug-description">

i wrote normal form so that this much mistake ....

thanks objects for your answer, I need both description and id.

I tried your solution but it does not work! and I actually don't get it how this hidden field will read the value of the selected index. could you please explain a little bit more?

> thanks objects for your answer, I need both description and id.

then you'll need to do a lookup, its a fairly standard thing to do

Its  work in<input type="hidden> in <select>  
so it will work for <form:hidden>....



<form:option> is a loop  yes means

change the code like this

bcz the loop closed before hidden values is set so that only no value coming ....

<form:select id="drug-id"
        path="drug.id">
        <form:option value="0" label="select drug name" />
        <form:options items="${drugs}" itemLabel="description" itemValue="id">
       <form:hidden id="drug-name" path="drug-name">
</form:option>
</form:select>

The only way to make your way to work is to add onChange event to <form:select> to set the hidden field value.

The hidden field cannot be set by itself when the user select element from drop down list. You mentioned something about <input type="hidde"> within <select> tag, but this also gives warning and won't work.

I think you are missing the onChange event in your case, otherwise, I doubt it works unless you have a workable example.

<form:select id="drug-id" path="drug.id" onChange="document.getElementById('description').value=this[this.selectedIndex].text;">
        <form:option value="0" label="select drug name" />
        <form:options items="${drugs}" itemLabel="description" itemValue="id"/>
       <form:hidden id="description" path="drug.description">
</form:select>

I am doing this, and I am going to accept your solution, I just found *dravidnsr* insisting on the validity of his suggested solution, so I thought may be he knows something we don't.

http://www.experts-exchange.com/Programming/Languages/Java/J2EE/Frameworks/Spring/Q_24724967.html

check this u know !!

Ur hidden filed id is ur itemLabel only so what ever value ur selected that will set that hidden filed too........

In regards to the link you are referring to, that peson is using for loop to populate the options, but I am not doing this, <form:options/> will impliclity loop over the {drugs} in the request and build the options. Besides that solution will add many hidden fields while in the solution I posted above, I need only to use onChange event to set only ONE hidden field instead of adding hidden field for each option.

Thanks for your time an help, I am going with the backed loop.
Thanks for both of you :)
