Hi guys, I'm using tapestry 5.4-beta 3 and I have a keyword search on my website using the auto complete mixin. I'm seeing the following exception appear in my logs 100's of times. I have been unable to reproduce it, so im assuming it is happening as a result of bot activity, but I can not confirm. Does anybody know the cause or how to repair it?
org.apache.tapestry5.runtime.ComponentEventException: Unable process query parameter 't:input' as parameter #1 of event handler method org.apache.tapestry5.corelib.mixins.Autocomplete.onAutocomplete(java.lang.String): The value for query parameter 't:input' was blank, but a non-blank value is needed.
