Error in context binding for text property

Question

Hello experts,
I receive this error in my WD4A application:
The following error text was processed in the system XXX : Context binding for property TEXT of "T_MONTHTO"
cannot be resolved: Node MAINVIEW.1.TEMPVAL2 does not contain any elements
The error occurred on the application server sapxxxxx_XXX_00 and in the work process 0 .
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
TEMPVAL2 has cardinality 0..1, selection 0..1, Inizialization Lead Selection false and the ST22 dump says:
33
34   if l_adapter->m_view_element is bound.
35     l_component ?= l_adapter->m_view_element->view->if_wd_controller~get_component( ).
36     l_view_name = l_adapter->m_view_element->view->name.
37     l_view_element_id = l_adapter->m_view_element->id.
38     l_component_name = l_component->component_name.
39   endif.
