Well it's more complicated than that, I guess. Exactly is to compare two ID
attribute between two objects (the rest of the attributes may be different),
so I'm thinking in create the external OGNL variable and set it to "true"
when the element is found (as I said in my previous post).
...
Ok. Finally I've made it! : ) But every time I want to modify an OGNL
variable I have to create an <s:if test=%{#variable=value}> tag. Is it
correct? How can I operate with OGNL variables without using this tag?
BTW thank you for your response Laurie, I've wrote it in my magic diary ;)
