Hi all,

Whenever i am trying to use a check box or a chekbox group in my UI , i am getting following error

The initial exception that caused the request to fail, was:

java.lang.NoClassDefFoundError: com/sap/tc/webdynpro/clientserver/uielib/standard/api/IWDAbstractToggle

at java.lang.Class.getDeclaredConstructors0(Native Method)

at java.lang.Class.privateGetDeclaredConstructors(Class.java:1618)

at com.sap.tc.webdynpro.progmodel.generation.DelegatingView.<init>(DelegatingView.java:41)

How to get rid of this error??

PS: I am not an expert in WD but a newbie

Hi Ameya,

Bind the checked property of checkbox to a boolean type context value attribute.

bindchecked property is must to use a checkbox.

If your are getting problem after this-

check the action you are giving in ontoggle event.

It was NWDS version and WAS version conflict. The check boxes workes on newer version of WAS. However, on WAS 6.40 it gives error.
