Konstantin Spirov updated RF-7527:
----------------------------------

    Workaround Description: 
Workaround for problem 2 1 from user's perspective):

Add in rich:suggesstionBox

 <a:support event="onselect" reRender="yyy"
                                       ajaxSingle="true">
          <f:setPropertyActionListener value="#{result.our_column}"
           target="#{backingBean.our_attribute}"/>
 </a:support>

The data will flash on the screen, but will be at least recovered in a while. Additional ajax request is made :-( .

Workaround for problem 2 (from user's perspective):

Surround all code (h:inputText & rich:suggestionbox) with  <a4j:outputPanel  id="yyy">
Change in a4j:support reRender="xxx" to reRender="yyy"

 This workaround is not satisfying, because now you get other problem - Scenario 2 for https://jira.jboss.org/jira/browse/RF-7526 which is nasty and not
always repeatable.

>                 URL: https://jira.jboss.org/jira/browse/RF-7527
>             Project: RichFaces
>          Issue Type: Bug
>          Components: component-input
>    Affects Versions: 3.3.1
>         Environment: The scenario is for Firefox 3.5 and Opera 9.1, RichFaces >= 3.1
>            Reporter: Konstantin Spirov
>         Attachments: test.xhtml

> There are 2 problems mentioned here, but I am combining them in one report, because  the test scenario I will provide is the same. The workarounds I am providing are not satisfying.
> The two these problems are in construction like:
> <h:inputText style="margin:0px;" id="xxx" value="xxx">
>                     <a4j:support event="onblur" reRender="xxx" bypassUpdates="true" ajaxSingle="true"/>
> </h:inputText>
> <rich:suggestionbox for="xxx">
> The approach is a4j:support rerender=xxx is *very standard* (see seam-gen for examples), and it is practically necessary if we want to modify automatically from the server the field after it is changed.
> Problem 1: Display suggestion list and click on some suggestion (with the mouse). The value will be updated for a while, then *the old content* is recovered (incorrectly ). We have again empty field, which is very annoying. PLEASE notice that if you had used arrows and tab from the keyboard, everything would work correctly - so there is a solution, but it doesn't work when the user clicks with the mouse (our users usually click with the mouse, don't use keyboard  :-) 
> Problem 2: JavaScript error if you try to display the suggestion again (see your browser console).  The suggestionbox stops working until you reload the page.
> Exact steps to reproduce quickly test platform (I am sending  an attachment just for refference - it is similar)
> 1) Take from Richfaces showcase RichInput:SuggestionBox:ObjectsUsageExample
> 2) Add value="#{bean.attribute} to <h:inputText (create the "bean" in the most quick and easy for you way, in my platform it is seam component in conversation scope)
> 3) Inside  <h:form> wrap with <a4j:queue> (probably not necessary, but let's not risk the repeatability of the scenario)
> 4) From rich:suggestionBox remove:
>             usingSuggestObjects=...
>             onobjectchange=...
> 5) Add in h:inputText <a4j:support event="onblur" reRender="statesinput" bypassUpdates="true" ajaxSingle="true"/>
> You will see that the last step line makes everything unusable :-(
