Parameters/variables in Lookups

Hm, rather no good idea as far as my experience goes.

My setup

My setup is a mapplet that uses a lookup and in this lookup I use a Lookup Source Filter which in turn uses mapplet parameters with default to define values to match against. I wanted therewith reduce the cache size and efficiency of the processing.

Result

The parameters were not replaced by their respective value defined in the parameter dialog of the mapplet menu.

Explanation

It seems that the parameter replacement, for no apparent reason to me, omits Lookup Source Filters.

Workaround

Use Lookup Sql Override to get parameters into the where clause of the SQL for the lookup cache.
