call method in managed bean by onChange

hrbaer Jul 15, 2009 6:02 AM

Hi,

I'm trying to call a method in my managed bean by using the js-function onchange.
The reason is that an input field should be filled when s.o. leaves another input field. Dependent on what the user insert in the first field the value of the second field varied.

My Code:

<h:inputText value="#{mb.field1}" onchange="#{mb.test}"/>

In this case I'm getting an error that there is (of course) no property 'test' in my mb.

Is there a possibility to solve this problem?

probably you should explore documentation for a4j:support.

I'm trying to call a method in my managed bean by using the js-function onchange.

server side method call from client side event handlers not possible without a4j:support or a4j:jsFunction usage.

Hi,

the origin problem is followed up by another issue.
If you leave the input field f.ex. with the tab the next field get automaticly filled by the a4j:support-Tag. BUT, I'm loosing the focus on that input field.

Is there a possibility to fill the inputfield and still have the focus on it?

Thanks in advance!

Ok, solved it by myself.
There is a attribute focus on the a4j:support tag!
