I am just trying to display a Context Menu with CheckBox items as shown below

But am getting the below error while selecting the checkboxes.

Caused by: java.lang.NullPointerException: while trying to invoke the method com.sap.tc.webdynpro.progmodel.context.AttributePointer.getElement() of a null object loaded from local variable 'property'

Hi samba,

your error shows that there is java.lang.null pointer exception...

i.e you are trying to access a node with cardinality 0...n and which does not have elements in it.

so try to fix that issue , it wil solve your problem,  another thing is on click of select

put the below code

if(null != wcontext.currentcontextelement().getxxx())

{

    your code to do if check box is selected

}
