[Gvsig_english] SUGGESTED FUNCTIONALITY gvSIG 1.9 (BN 1253) -- Permanent Filter Shapefiles

[Benjamin Ducke]

Last time I checked, the "Expression" type filter you mention
below did not work on fields joined from an external table.
I think this is the problem that Simon ran into.

Simon,
there's actually the possibility to define a quite close "definition query":
Layer Properties --> Simbology tab --> Categories tree --> Expressions
option --> click on New expression of filter --> ...and so on
The only missing feature is that the filter is not applied to the table
of attributes. Hope this helps!

Cheers,
Antonio
