Class MapRenderAdapter<M extends Map>

java.lang.Object

com.neurosys.template.wicket.itemadapters.CustomItemComponentRenderAdapter

com.neurosys.template.wicket.itemadapters.MapRenderAdapter<M>

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

JSONRenderAdapter

public class MapRenderAdapter<M extends Map>
extends CustomItemComponentRenderAdapter

Adapter to render a Map as a series of Key-Value inputsSelect (single or multi-select depends on the ContentType in MetaItem)
If the core input Object is not a Map then one should ensure that the core input type is converted to Map and back by setting CustomItemComponentRenderAdapter.setModelTransformer(org.apache.commons.collections.Transformer) with a TwoWayTransformer
The list and sequence of fields used depends on #getLookup() if not entityTemplate is provided. TODO: This adapter cannot be used with ProductDetailsTemplatePanel as the entityTemplate is of EntityTemplate type. We need to adapt it to also work with ProductDetailsTemplatePanel.

getComponent

public org.apache.wicket.Component getComponent(String componentId,
                                                MetaItem metaItem,
                                                org.apache.wicket.model.IModel defaultInputModel,
                                                Object modelObject,
                                                User user)

Some fields/attribute may require display of options for selection or Auto-Suggest etc..

Providing rendering option for lookup for that field/attribute. The base class returns a Hidden field, which can be overriden by any derived adapter.
If no mapping exists, then null will be returned.
Base class implementation returns HiddenField Expect the modelObject as JSONObject and make a ListView of all the key, value pairs.

Overrides:

getComponent in class CustomItemComponentRenderAdapter

Parameters:

componentId - as Sting id for the Component

metaItem - as MetaItem meta data for rendering logic

defaultInputModel - is the current data defined in a IModel for the MetaItem. The resultant model in the returned Component may NOT be same as the one passed to the inner component, hence always use the derived one. This is because there maybe a mismatch in the form of core/raw data and one required for final presentation. For example the input maybe a Comma Separated list of Strings, however for presentation in a List box we may convert the Model to a ListModel.

modelObject - as Object, that represents the main Entity (overall context)

user - as com.neurosys.security.auth.domain.User for any Authorization related needs @nullable true

Returns:

Component @nullable true

populateItem

protected void populateItem(org.apache.wicket.markup.html.WebMarkupContainer item,
                            org.apache.wicket.model.CompoundPropertyModel model)

Model of the input data to the Component
If entityTemplate is provided then it will render a Dynamic EntityDetailsTemplatePanel; using Template.getReference(). hence in this case Template.getReference() must not be null.

Parameters:

item - as ListItem

model - as CompoundPropertyModel

getEntityTemplate

public EntityTemplate<Map> getEntityTemplate()

setEntityTemplate

public void setEntityTemplate(EntityTemplate<Map> entityTemplate)
