T5.1 If/Conditional against a method?

2009-08-13 Thread Michael Gentry 
Hi all,

I've been searching the documentation/examples/list all morning, but
can't find an answer to this so far.  Can T5.1 do a conditional
against a method instead of a variable (property)?  I have something
like:

div t:type=If test=showFoo.../div

For the Java, I have tried numerous varieties of:

protected boolean showFoo() { ... }

(isShowFoo, getShowFoo, etc, etc)

I keep getting an exception that it can't convert showFoo to a
component parameter binding, then it shows me all the variables (not
methods) in my class.  Of course, you can't put an @Property on a
method, either.  Is it not possible in T5 to bind your conditional to
a method?  (T4 could do this.)

Thanks,

mrg

Hi!


div t:type=If test=showFoo.../div


Try div t:type=If test=showFoo().../div. Notice the parenthesis.  
Without them, Tapestry looks for get or is methods.

One can also use the Chenille Kit's OGNL binding and do more  
complicated tests, I'd imagine.

If you want the method to be showFoo(), then you need to do  
test=showFoo().
But you can use test=showFoo if showFoo() is renamed to isShowFoo,  
iff you change the accessor to public (from protected).
That is, for property access, tapestry is following java beans  
conventions, and a property is only a java beans property if it's  
public. :)

Thanks Thiago/Robert!

Both of your suggestions worked (although I had to change the method
to public instead of protected for both).  I didn't try Norman's
(although I'm sure OGNL would be fine) because I'm not using CK (at
least not yet).
