Don't forget that the dynamic attribute may have its own type (double or date for example). In this case, it would be useful to follow some conventions like - start the attribute name with a special character (not too special though) - include the attribute type in the saved string
There is another deeper problem. Currently, a dynamic attribute is not just one containing a script, it is one containing an "Operation" (just an interface doing anything and returning anything) Means that we must also persist which kind of operation is this dynamic attribute to be able to restore it as a working script. Note that making attributes dynamic could be done with a few modification in the feature package, but I think that persisting formulas will need to patch every single reader/ writer. Or maybe an "adapter" taking place between DataSources and FeatureCollections to "interpret" stored formulas would help... Just some thoughts, Michaël PS : I'm quite sure that some will want to persist formulas and others the data ;-) > > ..ede > > ------------------------------------------------------------------------------ > Don't let slow site performance ruin your business.
