Access JSON via a variable within a gsp

Question

There is following JSON structure given:

"filter": {
    "1": {
        "value": "swiss"
    },
    "2": {
        "value": "google"
    }
}

How to access the variable "value" via an index variable within a gsp template like this?

<g:each in="${...}" var="data" status="i">
    ${filter?.i?.value} 
</g:each>

If your "key" there is a variable you can use a GString notation like for any other property referenced by variable:

${filter?."$i"?.value}

Is that what you are looking for? It's without index variable.

<g:each in="${filter}" var="data" status="i">
    ${data.value.value} 
</g:each>

data.value.value (no ?. needed here, as you iterate over it and it's a map, so data would be an element)

Thank you very much for your answer. It is also right, but in my case I want to iterate over another structure.
