Hi Stuart,
If you're not already on the dev_at_jsftemplating.dev.java.net email alias,
you may want to join that list. You can find it on the JSFT web site
(
https://jsftemplating.dev.java.net).
The problem is that JSFT does wrap MethodExpressions automatically by
default. For now, it's up to the individual ComponentFactory's to
create a MethodExpression (instead of a ValueBinding, which it does do
by default). I may enhance JSFT to try to do this correctly in the
future... at least for action/actionListener properties, which are standard.
There are 2 easy ways around this problem, and probably many other
approaches as well. The reason this issue hasn't been targeted to be
addressed sooner is that most JSFTemplating developers use the "command"
event instead of using an action/actionListener. To do this you would do:
<webuijsf:hyperlink action="gosomewhere">
<ui:event type="command">
navigate("/nextPage.jsf");
</ui:event>
</webuijsf:hyperlink>
No need for any faces-config.xml file entries at all. Instead of
"navigate" you can also do "redirect". And... you may also do any king
of processing you can think of. You can have as many handlers per event
as you'd like... they get executed in the order you write them. You can
do coditionals if ("#{something}=foo") { doThis(); }, etc. There is
some information on this at:
https://jsftemplating.dev.java.net/doc/
More information on this will be published soon (I plan to focus on this
during my Christmas vacation).
The 2nd way to get around this problem uses a special syntax to create a
MethodExpression from within the template file:
<webuijsf:hyperlink action="$methodExpression{gosomewhere}" />
That should work for an "action" property. The following should work
for an actionListener property:
<webuijsf:hyperlink action="$methodExpression{gosomewhere,true}" />
For a MethodBinding (only works for actionListener property on JSF 1.1
components):
<webuijsf:hyperlink action="$methodBinding{gosomewhere}" />
I hope this helps... let me (and the rest of the dev_at_jsftemplating email
list) know if you have more questions / problems. I am taking time off
at the moment to do some work on my house... so I may not respond
quickly. The email list is your best resource.
Good luck!
