Hi Guys,
If anyone has experimented with OGNL, can they tell me if this statement is legal.
In the .jwc for my component I had this expression:
<jwc name="ifToDisplay" type="Conditional" />
<binding name="condition"
expression="components.foreach.index >= itemIndex &&
components.foreach.index <= itemIndex />
</jwc>
I'm going from memory here, so there may be syntax error, so for argument's sake,
assume all my bindings are OK - they are.
The Tapestry parser complained about the ">=" bit. It suggested "<" but when I did
this it complained wanting a ";" after the lt.
I gave up and coded the conditional the usual way.
After this little exercise, I came to the conclusion like some other guys here, that
business logic should stay hidden awawy, and not be expressed using OGNL.
IMO making much use of OGNL I think will dilute the structure of what are inherently
well-structed Tapestry Pages/components and make difficult to maintain, not to mention
it just looks crap.
Am I right off track here? If others have used OGNL in Tapestry, in neat, clean manner
I am interested to see how.
Regards,
Pat.
