Konstantin Spirov commented on RF-7527:
---------------------------------------
Here is the scenario with queue and rendering of parent component (if my
attachment does not speak for itself)
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> (!!!)
3A - NEW) Inside a4j:queue wrap with:
<a4j:outputPanel id="XXXXX">
4) From rich:suggestionBox remove:
usingSuggestObjects=...
onobjectchange=...
5) Add in h:inputText <a4j:support event="onblur" reRender="XXXXX"
bypassUpdates="true" ajaxSingle="true"/>
5A - NEW - PROBLEM 1:
A) Click with the mouse on the selection list (right mouse button). The field
will become empty ( incorrectly)!
B) Do again a selection and navigate with tab (not with the mouse) - the field
is not empty - with keyboard (it works)
5B - NEW - PROBLEM 2:
Do a bulk clicking on the arrow. From time to time the sellection will be
positioned on a wrong place. With queue, with rendering of parent component!

> Key: RF-7527
> 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
> Assignee: Tsikhon Kuprevich
> 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 :-(
