Error Message while executing the Application

[Former Member]

Hi,

I am new to Webdynpro and I created my first application by following some blog on a portal.I was able to activate my application successfully and when I executed I get this below error message.

I checked the cardinality and it is 0..1.My Inti.Lead Selection is set to NO.

I mappedthe nodes in my views also. But still i don't know whay am getting this error.

Note

The following error text was processed in the system RS2 : Adapter error in &VIEW_ELEMENT_TYPE& "VBELN" of view "Z_MYFIRST_WEBDYNPRO.MAIN": Context binding of property VALUE cannot be resolved: Node MAIN.1.NODE_VBAK does not contain any elements

The error occurred on the application server ucerp18_RS2_00 and in the work process 11 .

The termination type was: RABAX_STATE

The ABAP call stack was:

Method: RAISE_FOR of program CX_WDR_ADAPTER_EXCEPTION======CP

Method: RAISE_BINDING_EXCEPTION of program CL_WDR_VIEW_ELEMENT_ADAPTER===CP

Method: GET_BOUND_ELEMENT of program CL_WDR_VIEW_ELEMENT_ADAPTER===CP

There was some error in a method and I corrected it.

Thanks to you all for sharing your thoughts.

Kiran,

For your input fields cardinality must be 1:1 and also check the Initialization lead selection check box in properties.

Thank You,

Hi,

I changed the cardinality to 1:1 and I can see the selection screen. But, can you please explain why I should change this from 0:1 to 1:1.

Now I have a new error:

After I enter the sales order Number and hit my FIND button, am getting this error:

The following error text was processed in the system RS2 : Could not find attribute VBELN

Thanks,

Kiran

Now am getting a different error:

Invalid operand type for the MOVE-CORRESPONDING statement

Thanks

Kiran

Hi Kiran,

I faced similar kind of error when the binding was not created in the view properly.Check if the binding is proper and also the cardinality should be 0:n and selection 0:1

Thanks,

Main view is like my selection-screen so i have only input fields and my cardinality is therefore 0:1 .

My second view (Secondary) is ALV and i maintained 0:n cardinality. Pl let me know, if this is the right way.

Coming to binding on main view...in my input fields, i can clearly see the names like: MAIN.NODE_VBAK.VBELN & MAIN.NODE_VBAK.ERDAT in my 2nd input field. I think, this clearly indicates binding is done properly.

Please let me know if am wrong and any more clues.

Thanks

Hi Kiran,

Please check whether the Lead Selection is set or not, If not set the lead selection.

Hi Kiran,

You have created a node in the context .to which UI element are you binding it..

Is it for table or some input field.

if its for table the cardinality should be 0:N

if its input field it should be 0:1 so that you dont get any errors has context doesny have any elements .
