ADF : Change View Criteria Columns at Runtime

When creating view criteria related to view object, then all querable attributes are displayed in view criteria by default.

I developed the following method for this purpose, You can add this method to ViewObjectImpl class.

I pass attribute name and a Boolean value to determine display in view criteria or no.

 public void setQuerable(String attributeName, Boolean isQuerable) {  
     int indx = this.getAttributeIndexOf(attributeName);  
     ViewAttributeDefImpl attr = (ViewAttributeDefImpl)this.getAttributeDef(indx);
