Multiple ALVs in a single view - dropdown not populated

Hi,

I have a web dynpro window in which I am having 2 ALVs. I have created 2 refernces to the class "CL_SALV_WD_CONFIG_TABLE" for each ALV (MR_ALV_1 and MR_ALV_2). The data to the ALVs comes from a node (MR_NODE_ALV).

Now in the ALvs I have a column which is a "dropDownByKey". I am filling the values by getting the NODE_INFO of MR_NODE_ALV. The NODE_INFO is populated correctly with required entries for both ALVs in the same way.

In the respective column of ALV1 I am able to see the dropdown entries. However in ALV2, I am not able to see any entries in the dropdown.

Could you please tell why?

Thanks,

Shalini.
