The default panel shows the properties in the order indicated by the symbolic name of the properties defined in my workflow (the file in attachment shows the print screen of the current situation).
I have to group the properties according certain criteria; for example the set of the readonly properties in a subpanel, a set of other properties in a second subpanel, etc...
Reading the redbook "Customizing_Extending_IBM_Content_Navigator" I saw an example on how to implement a layout plugin, but this case, it is only an assembly of different panels.
I need to override the function that retrieves the attributes of the opened work item and modify the rendering of these on the properties panel.
Can anyone suggest me a starting point to extend the widget and achieve the desired behavior?
