This might be necessary as an early adaptor of the modeler to use features of the framework before Editor support is available| none| |name|String|no|Defines the name of the List Item as well as the name of the JS File generated. |Name needs to be unique for all LIs in the Model| ### Sub nodes: * SimpleProperties contains all Simple Properties of the List Object * NestedListObjects contains all nested ListObjects of the List Object #### SimpleProperties Node SimpleProperties contains a list of Simple Properties (1..N) of the List Item. The SimpleProperties Node does not have any attributes, but it has a list of SimpleProperty SubNodes. #### Example ``` ``` #### Properties | name | Type | optional | Annotation | Validations/Checks| |:---------------|:------|:---------|:----------------------------------------|:------------------| |name|String|no|Defines the name of the Simple Property|Must be unique in the List of simple Properties, (Methods and Validations?!?)| |type|Name of a Domain or JavaScript Type (Boolean, Sting, Object,...)|no|Defines the Type of the Simple Property.
