Suggestionbox question

[francof]

Hi

How do I call a server function in the onobjectchange event ?

What i want to do that if the user starts a new search by typing in a new value in the text box, my backing bean should set the property as null.
I tried using the onobjectchange event, but looks it takes only Javascript and I want to call some server code and use it like this -
onobjectchange="#{selectProductKey.setItem(null)}"



My code if it helps understand better.

<h:inputText id="itemCode"
 size="20"
 maxlength="30"
 label="Item code"
 autocomplete="off"
 value="#{selectProductKey.itemCode}" >
</h:inputText>
<rich:suggestionbox
 for="itemCode"
 var="resultItem"
 width="600"
 minChars="2"
 shadowDepth="4"
 shadowOpacity="4"
 cellpadding="2"
 ajaxSingle="true"
 suggestionAction="#{selectProductKey.suggestItem}"
 usingSuggestObjects="true"
 fetchValue="#{resultItem.itemCode}"
 nothingLabel="No items found" >

 <h:column> <h:outputText value="#{resultItem.itemCode}" /> </h:column>
 <h:column> <h:outputText value="#{resultItem.modelName}" /> </h:column>
 <h:column> <h:outputText value="#{resultItem.modelDescription}" /> </h:column>

 <a4j:support event="onselect" action="#{selectProductKey.selectItem(resultItem)}"
 reRender="itemDescription"/> <!-- reRender="itemDescription,chooseProductClassPanel" -->
</rich:suggestionbox>

Basically, I am looking for a "onunselect" action - the user backspaces or changes value in the text box. The onobjectchange is the event here I believe but I'm not sure how to call a server function.

thanks

you could use a4j:support to trigger request. but onobject change is not similar to onunselect.

Thank you Ilya

Pardon me, I did not understand when you say "to trigger request"

In the demo example, you use the onclick with a call to callSuggestion(true) - how would that help here?


Do I put a a4j:support event on the suggestionbox control or the inputText ?
Use onkeyup event?


thanks again
