Re: Parameters not using setters?
So maybe it was in Tapestry 4... we migrated a rather large app so
maybe I am just now discovering some side effects of the migration!
Anyhow, I need to know when a parameter has changed.
For the time being I do the test in setupRender.
Someone suggested ComponentResources.isBound("paramname") but this
only tells me when the parameter has been set for the first time, not
when it has changed.

code to implement an accessor method around a parameter-bound field,
and for code to invoke the method ... but Tapestry doesn't access it
that way.

Hello list,
Some time ago (5.0.?) when I had a component with a parameter, I
could
implement a set method which would do some additional "cleaning up".
For example:
@Parameter(required = true)
private RegistryCenter _selectedRegistryCenter;
public void setSelectedRegistryCenter(RegistryCenter value) {
_role = null;
_selectedRegistryCenter = value;
}
Now, it seems like in the last version(s) of Tapestry, parameter
setting is
not using the set methods!?!
If so (which broke my app BTW), what can I do to recuperate this
kind of
behavior (e.g. do something when a parameter is set).
Thanks,
Alex

Re: Parameters not using setters?
You can use ComponentResources.isBound("paramname") to determine if
the parameter has been set. Add it to your setupRender method.

Parameters not using setters?
Hello list,
Some time ago (5.0.?) when I had a component with a parameter, I could
implement a set method which would do some additional "cleaning up".
For example:
@Parameter(required = true)
private RegistryCenter _selectedRegistryCenter;
public void setSelectedRegistryCenter(RegistryCenter value) {
_role = null;
_selectedRegistryCenter = value;
}
Now, it seems like in the last version(s) of Tapestry, parameter
setting is not using the set methods!?!
If so (which broke my app BTW), what can I do to recuperate this kind
of behavior (e.g. do something when a parameter is set).
Thanks,
Alex
