suggestionAction method used in suggestionbox is called twice per request

[romyo0o]

Hello,

I'm using <rich:suggestionbox />

I wrote a method to handle suggestions list for suggestionAction attribute, and this method is called twice per one request!

Is this issue related to JSF life cycle, and what's the solution ?

- Below is the JSF tag and the method:

<h:inputText id="idTxt" 

value="#{managedBean.id}" />  


<rich:suggestionbox id="suggestionBoxId" 

for="idTxt" tokens=",[]" 
suggestionAction="#{managedBean.autocomplete}" 
var="result" fetchValue="#{result.id}" 
minChars="2" nothingLabel="No data" 
columnClasses="center" usingSuggestObjects="true"> 

and This is the autoComplete method:

public List<Bean> autocomplete(Object guiInput) 
{
 String input = (String) guiInput;
ArrayList<Bean> result =
new ArrayList<Bean>(); 

for (Bean bean: bigBean.getBeanList()) {

if ((bean.getId() != 0 && Integer.toString( bean.getId()).indexOf(input) == 0))
{
result.add(bean);
}

}

return result; }





 

Thanks,

After implementing Phase Listener,

I figured out that auto complete method is called twice in last JSF Phase (RENDER_RESPONSE), the log is shown below:

#############################

before: RENDER_RESPONSE 6

auto complete

auto complete

after: RENDER_RESPONSE 6

#############################

I did this test using rich faces 3.3.1GA and 3.3.3 final

I found the solution:

I removed (usingSuggestObjects="true") attribute and it works.

Now just one call for suggestionAction

I see that's a bug in 3.3.0 and still unfixed

https://jira.jboss.org/browse/RF-6456

But the question here is:

what's the effect of removing this attribute?

I read the documentation of the tag and i didn't understand what does this mean >>

"if true, a suggested object list will be created and will be updated every time when an input value is changed. Default value is "false"."

if it false - only fetch values came to javascript for insertion. And with objects additional list of complete object sent to client in order to store additional objects properties after selection. (check at livedemo) . If yuo performing just string autocompletion - it's even better to have it false for better performance.
