I want that a field is not allowed to be empty if a toggle is set to false.

This is the rule I came up with:

<RULES>
	<RULE>
		<IF>
			<NOT>
				<EQUAL>
					<PROPERTY name="VALUE" source="is_textlink"/>
					<TRUE/>
				</EQUAL>
			</NOT>
		</IF>
		<WITH>
			<NOT>
				<PROPERTY name="EMPTY" source="linktmpl_url"/>
			</NOT>
		</WITH>
		<DO>
			<VALIDATION scope="SAVE">
				<PROPERTY name="VALID" source="linktmpl_url"/>
				<MESSAGE lang="*" text="The Pageref not be empty!"/>
				<MESSAGE lang="DE" text="Die Seitenreferenz darf nicht leer sein!"/>
			</VALIDATION>
		</DO>
	</RULE>
</RULES>

As described here https://docs.e-spirit.com/odfs/vorlagenentwick/regeln/vorbedingungen/index.html the rule will only execute if the IF-statement is fulfilled but it doesn't seem to work.

The error is shown also if the toggle is set to true:

What am I doing wrong?

Hello Mareike,

as you wrote yourself, the rule is only executed if the IF statement is true. This means that the rule will be executed if the CMS_INPUT_TOGGLE is false and thus the FS_REFERENCE input component becomes a mandatory field.
If the TOGGLE is now set to true, the rule is not executed again, so the REFERENCE input component remains a mandatory field.
Solution: Insert both queries in the WITH tag, then it also works when you switch the TOGGLE back and forth.

Note: Basically, you should never query something in the IF that an editor can change. This always leads to effects like the one you can observe here!

Best regards

Thank you, I understand and got it working with a WITH 🙂
