Pre-populating a Spring MVC form - forms

Question

I am looking for a way to pre-populate a Spring MVC form from values stored in a session-scoped bean. (using this namespace: http://www.springframework.org/tags/form).
For example, say I have added a queryInfo object to the uiModel.
How do I display the name instance variable from the queryInfo object?
<form:input path="queryInfo.name" />
Is this possible? If so how?

Answer 1

In your request mapping, add the bean to the model:
model.addAttribute("queryInfo", queryInfo);
Then use modelAttribute in the form tag to bind it to the form:
<form:form id="some-form" modelAttribute="queryInfo">
...
Now name will display (provided there is a getter in your object appropriately named) when you do this:
<form:input path="name" />
Keep in mind form:input is a child tag of form:form. It is not meant to be used on its own.

#skel625's solution for form:input is perfect, but in the case of the form:select, with different option how do I set attributes? because in this way only works for the form:input
My form:select is like this:
<form:select path="dolorefastidio">
<option value="1"><spring:message code="questionnaire.compile.label.paindiscomfort.one"/></option>
<option value="2"><spring:message code="questionnaire.compile.label.paindiscomfort.two"/></option>
<option value="3"><spring:message code="questionnaire.compile.label.paindiscomfort.three"/></option>
<option value="4"><spring:message code="questionnaire.compile.label.paindiscomfort.four"/></option>
<option value="5"><spring:message code="questionnaire.compile.label.paindiscomfort.five"/></option>
</form:select>
