PM32595: RBD8 Rui: custom widget class is set with starting EglRui

APAR status

• Closed as program error.

Error description

• Environment:
  - Windows XP
   - Rational Buissiness Developer v 801
  Reproducible Y/N: Y
  Description of problem:
  User created a custom widget, DateField, as a copy of TextField.
  It must use the TextField styling.
  
  However, by default RUI assigns a class with the widget name:
  EglRuiDateField. It appears that EGL runtime sets the default
  class after calling
  the onConstructionFunction function.
  (In the setTagName function to be precise.)
  
  For example : following code in the 'rendered' page source :
  
      },
      'setTagName': function(/*String*/ tagName)
      {
          if (!tagName) return;
          this.eze$$DOMElement = egl.createElement(tagName);
          this.eze$$getDOMElement().eze$$widget = this;
          var parts = tagName.match(/(\w)(\w*)/);
          this.setClass('EglRui' + parts[1].toUpperCase() +
  parts[2].toLowerCase());
      },

  ****************************************************************
  The css class set in onConstructionFunction is overwritten
  by a default class "EglRui" + widget name, like below:
  
  handler MyWidget type RUIWidget {tagName = "div",
  onConstructionFunction = start, cssFile="css/RUITest.css",
  @VEWidget{ category = "Custom" }}
  
   function start()
    class = "MyClass";
   end
  end
  
  The class for MyWidget is "RuiEglMyWidget", even if the
  class has been set to "MyClass".
  
  This is because the default class will be set after the
  onConstructionFunction invocation.
  

Problem conclusion

• The solution is to not set the default class if the class
  has been set by the user in onConstructionFunction.
  

Temporary fix
