Nick Belaevski resolved RF-6956.
--------------------------------

    Resolution: Won't Fix
      Assignee: Tsikhon Kuprevich


Doesn't look like a RF bug. As far as I see, this happens because components are processed in the order in which they are defined on the page, so "update model" call for select is followed by "update model" call to slider overwriting value set previously.

Solutions:

1. Set value using action method
2. Make the first a4j:support ajaxSingle="true" or enclose select into a4j:region

> I have a combobox next to an inputNumberSlider.
> When the combo changes, the range, step and value of the slider must scale (this is some sort of unit converter thing)
> <h:selectOneMenu id="unit" value="#{shippingView.unit}" disabled="#{shippingView.allWeights}" converter="SelectCodableConverter">
> 	<f:selectItems value="#{shippingView.unitItems}"/>
> 	<a4j:support event="onchange" reRender="measure"/>
> </h:selectOneMenu>
> <rich:inputNumberSlider id="measure" label="Value" value="#{shippingView.value}" width="300" maxValue="#{shippingView.range}" step="#{shippingView.step}" inputSize="5" maxlength="5" required="true" disabled="#{shippingView.allWeights}">
> 	<f:validateLength maximum="5"/>
> 	<a4j:support event="onchange" actionListener="#{shippingView.doSelectShippings}" ajaxSingle="true" reRender="shippingList"/>
> </rich:inputNumberSlider>
> Problem is, after I programatically changed the slider's value, it's reset to the previous value, before the component is rerendered.
