Feature request: custom json objects in CustomValue or (better) customfield in fields definition

[szacchino]

Hi,
great work here! I tried to customize templates to allow generation of an HTML Select input for one of my fields. Currently I added a bunch of fields in the customValue field of base.json. Currently they are:

"fieldXY": 3,
"fieldXYvalue1": "1",
"fieldXYlabel1" : "Option 1",
"fieldXYvalue2": "2",
"fieldXYlabel2" : "Option 2",
"fieldXYvalue3": "3",
"fieldXYlabel3" : "Option 3"

that I parse in the template as

<#if (field.type?string == "com.liferay.damascus.cli.json.fields.Integer" && application.customValue[field.name]?? ) >
  <aui:select name="${field.name}" disabled="false" label='<%=LanguageUtil.get(request, "${lowercaseModel}-${field.name?lower_case}") + requiredLabel%>'>
    <aui:option value="" label="Select a value"/>
    <#list 1..application.customValue[field.name]?number as optionIdx>
      <#assign optionvalue = application.customValue[field.name+"value"+optionIdx?string] />
      <#assign optionlabel = application.customValue[field.name+"label"+optionIdx?string] />
      <aui:option value="${optionvalue}" label="${optionlabel}"/>
    </#list>
  </aui:select>
</#if>

I saw that customValue is implemented as a Map<String, String> so it is a sort of key-value map. Maybe a Map<String, Object> could be better for having custom objects in base.json that can be used in templates.
So in base.json it could be:

"customValue" : {
       "fieldXY": {
            "items": [
                {value:1, label: "Option 1"},
                {value:2, label: "Option 2"},
                {value:3, label: "Option 3"}
          ]
         }
      }

Even better could be having a custom object in the field definition so that one can specify custom code based on field data.
So for an integer field in base.json it could be:

{
  "type": "com.liferay.damascus.cli.json.fields.Integer",
  "name": "fieldXY",
  "title": "Field Title",
  "required": "true" {
  "items": [
     {value:1, label: "Option 1"},
     {value:2, label: "Option 2"},
     {value:3, label: "Option 3"}
    ]
}
