Web Dynpro ABAP - Select Option and ALV Component Usage

Question

Hi,
I'm new in ABAP Web Dynpro and i was trying to follow the SDN tutorial
Web Dynpro ABAP - Select Option and ALV Component Usage  
In this video, we create a new Web Dynpro ABAP component that uses both Select Options and ALV. Developers can learn the basic mechanisms for working with both of these reusable components.
Following the link: https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/media/uuid/39c54fe7-0b01-0010-0eb6-d63ac2bdd637
I implemented and generated the web dynpro with success but when i execute a test i get a dump on select-option definition.
Note
The following error text was processed in the system ECD : Exception condition "TYPE_NOT_FOUND" raised.
The error occurred on the application server ITAWSECCS01D_ECD_00 and in the work process 0 .
The termination type was: RABAX_STATE
The ABAP call stack was:
Method: DESCRIBE_BY_NAME of program CL_ABAP_TYPEDESCR=============CP
I went in debug and the piece of code dumping is:
lt_range_table =
wd_this->m_handler->create_range_table( i_typename = 'S_PROJ' ).
Is there someone who can help me?
Thanks in advance,
Stefano.

I have created a table zmy_table and trying to make USERID field as a select-options.I've written the code as shown below .
data: itab type standard table of zmy_table,
wa type zmy_table.
data:
node_employee type ref to if_wd_context_node,
elem_employee type ref to if_wd_context_element,
stru_employee type wd_this->element_employee ,
item_userid like stru_employee-userid.
navigate from <CONTEXT> to <EMPLOYEE> via lead selection
node_employee = wd_context->get_child_node( name = wd_this->wdctx_employee ).
@TODO handle not set lead selection
if ( node_employee is initial ).
endif.
get element via lead selection
elem_employee = node_employee->get_element( ).
@TODO handle not set lead selection
if ( elem_employee is initial ).
endif.
alternative access via index
Elem_Employee = Node_Employee->get_Element( Index = 1 ).
@TODO handle non existant child
if ( Elem_Employee is initial ).
endif.
get single attribute
elem_employee->get_attribute(
exporting
name = `USERID`
importing
value = item_userid ).
select *
from zmy_table
into table itab
where userid = item_userid.
node_employee = wd_context->get_child_node( 'EMPLOYEE' ).
node_employee->bind_elements( itab ).
Is there someone who can help me and can tell am i doing wrong?
Thanks in advance,
