Hi,

 

Need inputs on how to get handle of the business object  in custom code

 

My requirement is,

1) On button click read value from the business object

2) Update that value for that field

 

Code used in custom code for button -

 

/**************************************/

alert($COntactQueryListArchetypeRecord.getValue('conNUmber'));

resolve();

 

/******************************/

 

Getting error

Error: Cannot read property 'getValue' of undefined

 

Thanks,

Abhi
