Summary

Nintex Form Rule will not execute as expected when using the List Lookup Control output for the value used in Nintex Rule due to ID-prefix.

Resolution

While in the Nintex Form Designer, do the following:

• Alter the Rule to remove the ID-Prefix by using the replace() runtime function and adding the following RegEx:"^[0-9]+;#"

For Example:

• If 'test' is the first value in the list, the value would appear as: "1;#test".
• A formatting rule will be created to hide a different control, if the List Lookup Control, "LLUP" has a value of 'test'.
• The following Rule will be used: replace(LLUP, "^[0-9]+;#", "" ) == "test"
