whatever you type, both direct reply nodes will be triggered and respond with the numbers that shouldn't be responded.

✔️ Expected Behavior

when you type 1, branch 1 will be triggered, and 2, branch 2 will be triggered.

❌ Actual Behavior

both branches are triggered in condition node

@RoyDingZF Hello there! I'm here to help you with any bugs, questions, or contributions while you wait for a human maintainer. Let's tackle this issue together!

The issue you're experiencing, where both branches are triggered in the condition branch node, could be due to several factors related to the logic in the IfElseNode class. Here are some potential causes and solutions:

1. Logical Operator Misconfiguration: Ensure that the logical operators used in your conditions are correctly set. If both branches are being triggered, it might be due to a misconfiguration of these operators, causing both conditions to evaluate as True ^[1].

2. Condition Evaluation Error: Check if there is an error in how conditions are evaluated. This could be due to incorrect data in the variable_pool or incorrect condition definitions. Verify that the conditions are set up correctly using the supported condition types such as "Contains", "Not contains", "Start with", "End with", "Is", "Is not", "Is empty", and "Is not empty" ^[2].

3. Fallback Logic: If the new cases structure is not used, the fallback logic might be incorrectly triggering both branches. Ensure that the conditions and logical operators in the fallback logic are correctly defined ^[1].

4. Variable Pool Configuration: Review the variable_pool to ensure that it is correctly configured with the necessary variables and values for condition evaluation. The variable_pool should accurately reflect the inputs and expected conditions for your workflow ^[3].

By addressing these areas, you should be able to resolve the issue of both branches being triggered. If the problem persists, further investigation into the specific conditions and data used in your workflow might be necessary.

I think this can be resolved by adding a variable aggregator node before the template node.

not working for me.

I also encountered this problem. When there are two or more nodes connect to a if-else node, all answer nodes after the if-else node will be triggered. A workaround is to add a template node before the if-else node so that there is only one node connects to the if-else node.
