<logic:equal/> looks for an attribute with the given "name" and compares for
equality with the given "value". <bean:define/> not only creates a scripting
variable but also puts an attribute with the same name. Here you only modify
the value of the scripting variable and not the "attribute" value, which is
what the <logic:equal/> is going to look for which is not modified from the
initial "true" value and so you would end up executing that block of code
always.
You could do any of the following:
Use <bean:size> and compare the size to 0 using <logic:equal/> to check if
the collection is empty or not
Use <logic:empty/> to check the emptiness instead of the <logic:equal/>
