Issue: Binding form fields with Map in command object

[umeshs79]

Hi,

It seems there is issue with spring in binding form fields with map in command object.

Here is my code:
Command Class

public class MyCommand {

	private Map fields;

	public Map getFieldsMap() {
		return fields;
	}

	public void setFieldsMap(Map fields) {
		this.fields = fields;
	}
}

fields on from

	<c&#58;forEach var="field" items="$&#123;fields&#125;">
<input value="" name="fieldsMap&#91;$&#123;field.name&#125;&#93;" type="text"/>
	</c&#58;forEach>

Above code throws exception.
But if I initialize my Map objects explicitly as below it works fine

public class MyCommand {

	private Map fields = new HashMap();

	public Map getFieldsMap() {
		return fields;
	}

	public void setFieldsMap(Map fields) {
		this.fields = fields;
	}
}

Can anyone tell me how to log this bug in Spring Tracker. I am using Spring version 1.2.3

Regards,
Umesh

This isn't a bug, it is a misunderstanding

Spring is binding to entries *within* your map, it isn't binding to the map itself.

In otherwords, spring will never call

setFieldsMap(..);

it will only ever call

getFieldsMap().get(whatever your field name is);
