[Former Member]

Hi Experts,

I am working on my first Webdyn pro development. I am currently working on PM Module, and the requirement is to change the Notification. I have a 'Long Text' button, when pressed,a popup with standard view for long text 'WD_LONGTEXT' is called. I have embeded the standard view in a seperate window.

Access via 'NULL' object reference not possible

The error occurred in work process 1 .

The termination type was: RABAX_STATE

The ABAP call hierarchy was:

Method: GET_HEADER_LONGTEXT of program /1BCWDY/JFL8S42CBMK6B2RPMZZ5==CP

importing

et_longtext = et_longtext

et_return = lt_return

).

• add new lines from attributes

append lines of wd_this->mt_new_header_lt to et_longtext.

Hi Rajesh,

I am developing my first big webdynpro app too and sometimes I got this error.

Verify the cardinality and selection values.
