BSP view losing selected value from dropdown list box

Hi,

I am having a problem with an attribute on a bespoke view. The attribute itself was added to the model via EEWB.

It is defined as a 32 byte character field.

On the view there is a table defined as follows ;

<crmic:gridLayoutCell colSpan = "6"

columnIndex = "3"

horizontalAlignment = "LEFT"

rowIndex = "8" >

<crmic:dropdownListBox id = "TYP_COMP"

width = "100%"

table = "<%= dd_typ_cmpl %>"

nameOfKeyColumn = "DROPDWN"

nameOfValueColumn = "DROPDWN"

selection = "//BTCustomerH/ZZCUSTOMER_H0602"

disabled = "<%= disable_ddlb %>" />

</crmic:gridLayoutCell>

The values for the table are read from a Z table and populated in the method DO_PREPARE_OUTPUT ;

IF gt_typ_cmpl IS INITIAL.

SELECT * FROM zcrm_typcompl INTO TABLE gt_typ_cmpl.

ENDIF.

There are also several other attributes defined in exactly the same way , displayed on the same view , which all work as expected.

This view attribute is selectable from the dropdown list (works ok).

The issue is that everytime the view is refreshed (after saving transaction , error message display ec the selected value is lost and the whole table contents is reloaded , hence why the selected value is lost ?

I have checked all the code in the view and also the context node and it all looks the same as the other (working) fields..
