ID 126095 - Renderer procedural Args files: array-like widgets require 'size' and 'default' attributes to be specified

In Args files for renderer procedurals, assigning an array-like widget types, like 'dynamicArray' or 'sortableArray', to a parameter won't allow new items to be added unless the 'size' and 'default' attributes are specified to fake an array containing at least two elements.
For example, the following .args file wont' work:

<args format="1.0">    <string name="my_param widget="dynamicArray"/></args>

but this will:

<args format="1.0">    <string name="my_param" size='2' default=',' widget="dynamicArray"/></args>
