Decision Table changes become slow with Tree Mode on

I had a post on Tree Mode in OBR recently. I also did notice that the Jdeveloper became slow, sometimes unresponsive to changes being done in the dictionary when the option of Tree Mode was selected in the decision functions, that existed in the dictionary. I was able to work around that problem and I am now doing the below, when working with decision functions that use tree mode:

1. In the decision function of the decision table, uncheck the option tree mode temporarily
2. Make the changes in the decision table. The speed with which the changes reflect now will be the same as what it was initially
3. Make Sure, once the changes are done, the tree mode option is checked in the decision function

Even if you forget to check the option again in the decision table, no worries. Rule engine will not validate the dictionary and would not let the project to be deployed. The reason why the changes become slow when the tree mode is selected is not yet known officially, but my guess is that, the rule engine tries to validate the payload for changes in the tree mode, which means it has to iterate through all the elements. In the other case, the payload and definition must have been cached.

Peace!
