map values not populating in gsp

I Have the following controller:-

class HostController {

def index() {

def customMap = ['key1':'value1','key2':'value2']
[customMap : customMap]
}

}

and the following gsp view:-

<html>
<head>
    <meta name="layout" content="main">
    <g:set var="entityName" value="${message(code: 'host.label', default: 'Host')}" />
    <title><g:message code="default.list.label" args="[entityName]" /></title>
</head>
<body>

    this is the custom map      
    <g:each in="${customMap.value}" var="custom">
    ${custom}
    </g:each>
</body>

I am unable to print thae values of the map. Although I am able to print the keys using:

<g:each in="${customMap}" var="custom">
    ${custom.key}
</g:each>

I am not sure what is being missed here. Any help here is much appreciated.

Thanks, AMar

Solution

  • Change your gsp code to:

    <g:each in="${customMap}" var="custom">
   ${custom.value}
</g:each>

    You see, customMap is a recognized object which you passed from the controller to the view, customMap.value is not.
