Spring MVC + FreeMarker: How to render option tag?
The Spring 3 MVC docs state that option tags can be rendered like this:
<tr>
<td>Country:</td>
<td>
<form:select path="country">
<form:options items="${countryList}" itemValue="code" itemLabel="name"/>
</form:select>
&开发者_运维技巧lt;/td>
</tr>
I am using FreeMarker with Spring MVC, so I interpret this as:
<tr>
<td>Place:</td>
<td>
<@form.select path="place">
<@form.options items="${places}" itemValue="id" itemLabel="name"/>
</@form.select>
</td>
</tr>
When I hit the page I get the following exception:
freemarker.core.NonStringException: Error on line 40, column 73 in event.ftl
Expecting a string, date or number here, Expression places is instead a freemarker.template.SimpleSequence
What should I use instead of ${places} in my FreeMarker template so that the above works?
Thanks.
I was looking for exactly the same thing. I've no idea why this isn't included in Spring's Freemarker macro library, but fortunately enough it's quite easy to implement: Best practice would be to start your own macro library (say mylib.ftl
for example) and put the macro there:
<#macro selectOptions path options key value>
<@spring.bind path/>
<select id="${spring.status.expression}" name="${spring.status.expression}">
<#list options as option>
<option value="${option[key]?html}"<@spring.checkSelected option[key]/>>${option[value]?html}</option>
</#list>
</select>
</#macro>
You can then use your new macro in your Freemarker template like so:
<#import "/mylib.ftl" as mylib />
...
<@mylib.selectOptions "country" countryList "code" "name" />
HTH
You could try the following (not tested personally)
<@form.select path="place">
<#list Request.places as place>
<@form.option value="${place}" label="name" />
</#list>
</@form.select>
Hope this helps!
a little bit weird but it works.
- remove ${"places"} and use it straigh as places
- remove the itemid and let spring handle it for you
so you will have
<@form.select path="place">
<@form.options items=places itemLabel="name"/>
</@form.select>
