WD -Select options - DUMP -Practicing Rich heilman's app

Question

Hi,
I am practising the tutorial created by Rich heilman /people/rich.heilman2/blog/2005/12/20/using-select-options-in-a-web-dynproabap-application
I am getting following dump while running i browser.
Error when processing your request
What has happened?
The URL http://ssss.com/sap/bc/webdynpro/sap/ytest/ was not called due to an error.
Note
The following error text was processed in the system DV1 : Exception condition "TYPE_NOT_FOUND" raised.
The error occurred on the application server sape-dev_DV1_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
What can I do?
If the termination type was RABAX_STATE, then you can find more information on the cause of the termination in the system DV1 in transaction ST22.
If the termination type was ABORT_MESSAGE_STATE, then you can find more information on the cause of the termination on the application server sape-dev_DV1_00 in transaction SM21.
If the termination type was ERROR_MESSAGE_STATE, then you can search for more information in the trace file for the work process 0 in transaction ST11 on the application server sape-dev_DV1_00 . In some situations, you may also need to analyze the trace files of other work processes.
If you do not yet have a user ID, contact your system administrator.
Error code: ICF-IE-http -c: 180 -u: XXXXX -l: E -s: DV1 -i: sape-dev_DV1_00 -w: 0 -d: 20090112 -t: 162129 -v: RABAX_STATE -e: RAISE_EXCEPTION
All I did is i used a different table and follwed all steps.
Rich,
Thank you for the wonderful blog.
Any idea?

Answer 1

Rich,
Here is what I did.
I changed SFLIGHT TABLE to PROJ and tried to put only one select-options for field PSPNR.
Node name = PROJ.
I kept a break-point in these methods but  it got dumped before that only.
method WDDOINIT .
data:
lt_range_table type ref to data,
rt_range_table type ref to data,
read_only type abap_bool,
typename type string.
data:
lr_componentcontroller type ref to ig_componentcontroller,
l_ref_cmp_usage type ref to if_wd_component_usage.
* create the used component
l_ref_cmp_usage = wd_this->wd_cpuse_select_options( ).
if l_ref_cmp_usage->has_active_component( ) is initial.
l_ref_cmp_usage->create_component( ).
endif.
* get a pointer to the interface controller of the select options
*component
wd_this->m_wd_select_options =
wd_this->wd_cpifc_select_options( ).
* init the select screen
wd_this->m_handler =
wd_this->m_wd_select_options->init_selection_screen( ).
* create a range table that consists of this new data element
lt_range_table =
wd_this->m_handler->create_range_table(
i_typename = 'S_PSPNR_ID' ).
*add a new field to the selection
wd_this->m_handler->add_selection_field(
i_id = 'S_PSPNR_ID'
it_result = lt_range_table
i_read_only = read_only ).
endmethod.
method ONACTIONCONTINUE .
data: node_proj type ref to if_wd_context_node.
data: rt_pspnr type ref to data.
data: iproj type table of proj.
data: wproj type proj.
field-symbols: <fs_pspnr> type table.
* Retrieve the data from the select option
rt_pspnr = wd_this->m_handler->get_range_table_of_sel_field(
i_id = 'S_PSPNR_ID' ).
* Assign it to a field symbol
assign rt_pspnr->* to <fs_pspnr>.
* Retrieve that data from the database. Normally it is suggested to
* encapsulate the data retrieval in a separate class.
* For simplicity, the SELECT statement has been implemented here.
clear iproj. refresh iproj.
select * into corresponding fields of table iproj from proj
where pspnr in <fs_pspnr>.
* Bind the data to the context
node_proj = wd_context->get_child_node( name = `PROJ` ).
node_proj->bind_elements( iproj ).
endmethod.
