I have to display the navigation items based on user entity tags. So i have decided to extend the Core component Navigation model and filter those results.
But i get this error with the core Navigation component. I believe the error is in the below line
data-sly-test.hascontent="${navigation.items.size > 0}"
Any suggestions or fixes?
Stacktrace:
Caused by: org.apache.sling.scripting.sightly.compiler.SightlyCompilerException: Operands are not of the same type: comparison is supported for Number types only.

Below code should not be the issue. But check if navidation.items.size is returning numeric
data-sly-test.hascontent="${navigation.items.size > 0}"
And also check your Sightly script for any comparisons being made between non-numeric values, such as strings or booleans. You should ensure that both operands are numeric values before attempting to compare them.
If you are comparing variables or properties, you should also make sure that their values are being correctly assigned and are of the expected type. You may need to explicitly cast or convert the values to the correct type before making the comparison.
Hi,
The Sightly block statement you shared
data-sly-test.hasContent="${navigation.items.size > 0}"
should not throw any error ideally because it is a part of navigation.html.
can you share the complete stack trace? and if possible share a few more details as in if how you've customized it.
Hi @ArchR ,
The issue must be with the extended model. You need to debug the Sling Model and check if while filtering the items are coming zero or some other unexpected behavior. Just check the size of items in Sling Model while debugging.

Hi @ArchR ,
Looks like, the error is in code, at a location where "Less or equal" comparison is happening as the error below mentions LEQ and not GT (greater than) binary operator.
at org.apache.sling.scripting.sightly.compiler.expression.nodes.BinaryOperator.leq(BinaryOperator.java:214) [org.apache.sling.scripting.sightly.compiler:1.1.2.1_4_0]
Do you happen to have any "<=" comparisons in your extended code?
Thanks,
Ram
