Hi Fati,

You can use the OnChange event of the combobox to implement logic when the user selects an element on the combobox.

I made that but it's not working 

The OnChange is an ajax event so I suggest that you watch the 

Hi,

With regards to comboboxes values (static binded entity values) available for selection, on the aggregate definition/test module, you don't get to use special list elements as they are not included on the entity itself. Is there any workaround for this?

After selecting one of those available values you can never set it back to a nullidentifier again. Is there any way to reset test values?


E.g.: Aggretate GetProducts with the filter 

CategoryId = NullIdentifier() or Product.CategoryId = CategoryId

As the CategoryId is a local variable with data type "Category Identifier" the only available values for testing purposes are those included in the entity's records, which means you will never be able to use any special list element such as {0,All}.

Thanks,
