hey Masa
I tried debugging the PAGE_BUILDER_PERS service, looked into the following methods
GET_EXPANDED_ENTITY
GET_EXPANDED_ENTITYSET
I found the following line of code in both the methods, after the data initialization section
/ui2/cl_gw_environment=>set_expand_process( abap_true ). try. init_phase_manager( ). lo_expand ?= io_expand. lo_edm_model ?= get_edm_model( ). lo_edm_data_provider = get_edm_data_provider( ). cache_one_blob_supported( exporting io_edm_data_provider = lo_edm_data_provider receiving rs_result = ls_cache_one_blob_supported ).
Does this look fine to you?
Thanks
Sandip
