A question with "coro" type

Suite and Optimus Suite 5
#1

I use the “coro” cell type with grid. I get value from the request, but it has different value somtimes. Some time it returns a id, and other time it returns a value.Why?

#2

I mean sometimes I get value and sometimes I get label. What I want to get is the only one. How do I do?

#3

I read the dhtmlxGridCell file. When the method “eXcell_co.prototype.setValue” is called at first time, the combo value can not be set. Only when I click the cell which type is “coro” and choose an different item, the exact value will be set to the combo. If I don’t do that, then I will get the combo label from the request. But I want to get the label value. How do I do?

Which API you are using to get value ?
As far as I can see, grid must always return value, not the label.
