BSP ASSIGNMENT ERROR WHEN SELECT A TAB IN TABSTRIP

Question

Hi all,
I have a dump when select one of the four tabs, in which three working fine.
Plese see the below dump and help as soon as possible.
Runtime Errors         MOVE_TO_LIT_NOTALLOWED                          
Exception              CX_SY_DYN_CALL_ILLEGAL_TYPE                     
       Occurred on     09/18/2006 at 20:51:05                                                                               
What happened?                                                                               
Error in ABAP application program.                                                                               
The current ABAP program "CL_BSP_MODEL==================CP " had to be 
terminated because one of the                                         
statements could not be executed.                                      
This is probably due to an error in the ABAP program.                  
Error analysis                                                                               
An exception occurred. This exception is dealt with in more detail below       
. The exception, which is assigned to the class 'CX_SY_DYN_CALL_ILLEGAL_TYPE', 
was neither                                                                   
caught nor passed along using a RAISING clause, in the procedure               
"IF_BSP_MODEL_UTIL~CONVERT_FROM_STRING" "(METHOD)"                            
Since the caller of the procedure could not have expected this exception       
to occur, the running program was terminated.                                 
The reason for the exception is:                                               
You attempted to overwrite the field "<L_FIELD>", although it is a             
constant (i.e. a numeric literal or a string literal). This is not             
allowed.                                                                       
The following objects are protected:                                           
- Character or numeric literals                                                
- Constants (CONSTANTS)                                                        
- Function module and method parameters with the type IMPORTING                
  REFERENCE                                                                    
- Untyped field symbols that have not yet had a field assigned to them         
  using ASSIGN                                                                 
- TABLES parameters, if the actual parameter is protected against              
  changes                                                                      
- USING reference paraemters and CHANGING parameters in FORMs if the           
  actual parameter is protected against changes                                
- Field symbols, if the field assigned to them using ASSIGN is protected       
  against changes (for example, key components of a SORTED or HASHED           
  TABLE)                                                                       
- External write access to an attribute with the READ-ONLY attribute           
I have the below error in webpage.
500 SAP Internal Server Error
Error message: Assignment error: A constant was meant to be overwritten. ( type of termination: RABAX_STATE

Hi,
  Go through the sample bsp application <b>SBSPEXT_HTMLB-> TabStrip.bsp</b> and check where you are going wrong.
   Post the code to point out where you are going wrong.
