Hello  
I need to put some properties to a costumer module but i have a lot of problem becouse i haven´t got any documentation only i have a javadoc.  
I want to put a property CT\_DATA to my component but it deployed well but it don´t show in designer when i´m going to look for this property.  
Example:  
addBoundProp(“iconName”, “Icon Name”, “The name of the icon that represents the current OSM Map.”,CAT\_DATA, PREFERRED\_MASK | BOUND\_MASK);

or

addProp(“animationRate”, “Animation Rate”, “The time between frames of animation, if it is turned on.”,  
CAT\_BEHAVIOR);  
I know the difference Cat\_XXX but i don´t know the fields PREFERRED\_MASK | BOUND\_MAS and how i make up a own propperties with the component and the relationship proppertie-component.  
I achieved remove same properties but i can´t create a new new one.  
Have anyone some example about this question.  
I don´t know how i put in the parameters in addProp or adEnumProp, etc inside function.
