eSpace expressions couldn't be optimized

In rare occasions you may get a "eSpace expressions couldn't be optimized" warning when publishing an eSpace.

When it happens, there is nothing to worry about! Your eSpace not being optimized doesn't mean that it is wrong.

What this warning means is that the Agile Platform compiler has identified a pattern that it COULD potentially optimize to save up on memory or performance but was unable to.

What you should do in this situation is to send the eSpace to OutSystems so we can analyse it to improve the Agile Platform to be able to contemplate the optimization for the pattern identified in your eSpace.
