What's the preferred way to change a property. Eg say I have a property count and I want to increment this each time the object is viewed. I've tried various constructs like <dtml-call count="count+1"> ....</dtml-let>, but the count always goes back to the original value.
This should do it: <dtml-call "propertysheets.YourPropSheet.manage_changeProperties({'count' : count+1})"> Keeping in mind of course that you still have that ages old "this creates a transaction each time the method is hit" issue that's come up with the previous counter products... Kevin
