to be fair, you have no choice but to use IE. The decision tree rule form is one of the few remaining ruleforms limited to IE-only. It's possible the reason you did not see anything after clicking Create and open is because of pop-up blockers. If you are using a browser other than IE, a pop-up window opens with a message This ruleform is currently only compatible with Internet Explorer.
I tried creating the Decision Tree rule again after turning off the pop-up blocker in IE but was unsuccessful. This is what I tried:
1. Turned off the popup blocker. For IE version 11 this involved going to IE's Internet Options>Privacy>"Turn on Pop-up Blocker" ticked OFF. Then I closed my IE browser session and reopened a new one and logged on to Pega 7 Designer Studio (DS) again.
2. Redo step 5 of the exercise: "5. Make any changes you may want to the label name, check the identifier and then click Create and open to create the decision tree rule."
3. Upon clicking Create and open DS simply closes the Create Decision Tree tab. There is no rule configuration window displayed as per step 8 of the exercise. It seems like the create process just terminates without doing anything.
4. I double-checked that IE's pop-up blocker was still off and it was.
Anything else I could try in order to resolve this issue?
I can do steps 1 and 2. Upon doing step 3, I get the a single line item CandidateScoring in the DecisionTree window but thats it. I was hoping that I could double-click on CandidateScoring to open a decision tree editor of some kind, but nothing happens. Should something happen as a result of this action?
So right now I'm still unable to configure this decision tree. Any other ideas for completing this.
