Using onchange without AJAX on <h:selectOneListBox>

[haefti]

Hi!

Is it possible to invoke an action method when changing the selected value on a <h:selectOneListBox> element?

I'm suppsoed not to use a4j even though this is the easiest way.

onchange="submit()" is not enough for me because it only submits the form but does not invoke the method I need to call.

I tried valueChangeListener="#{myBean.myMethod}" but nothing happened when changing the selected value.

Maybe someone can help me with this problem.

Thanks!

It's so trivial to do this with a4j.  If you have customers who are weird you can say no to their weird requests...

You can do this in JS - get hold of the button object, and call .click() on it.

Thanks for the advice but my problem is that there is no button with the appropriate method call as action attribute.

Using an invisible button could be an opportunity but it is nothing I really prefer to do.

It could be easier to help you if you explained if theres is a logical reason for not using a4j

The reason is called customer but it is not logical. ;-)

I have had my own share of crazy customer requests... but this one makes me really curious... your customer simply chose a particular .jar in you WEB-INF\lib and said do no use this? using some kind of ouija with the contents of WEB-INF\lib the alphabet? and what if the next time he selects jboss-seam.jar?

I know this is a little bit off topic, but most of the craziest customer that have had do not even understand the contents of WEB-INF\lib (and are no masters of witchcraft, so they wouldn't use a Ouija to arbitrarily forbid some .jars inside ;-) ), so please forgive my curiosity... can you share your story? (Maybe we can come up with some kind of irrational argument that might convice your customer that another magical artifact makes it lawful to use a4j because it overrides the power of the ouija used to forbid it ;-) )

Or even easier, perhaps you could rename the .jar or rename the prefix in your .xhtml? or better start a fork named a5f (the name makes no sense, but neither the request of you customer) upload it to Google Code, download it, and then you tell your customer that you are not using a4j anymore ;-).

Mmmm, I am getting the weird feeling that maybe you customer didn't ask you to not use a4j but instead to not use AJAX... Am I right?
