RichFaces: How to reset page in datascroller after changes of values in dataTable

Question

I have rich:datascroller for my rich:dataTable which is working well except that when I am on any page number (let say 5) and do a search operation (or any operation which renders the dataTable). Pagination will still show page 5, but I want it to be reset to 1. page when the operation happens.

In this image, when I am going to Page 5 and hit Search again or do a clear and search again, the pagination is still set to Page 5, not back to Page 1.

Here's my code snippet:

<rich:datascroller id="prodDataScroller" for="prodClassificationOutputTable"
                   rows="100"   maxPages="10" fastStep="3" renderIfSinglePage="false"
                   immediate="false" page="#{prodClassificationBean.firstPage}">
</rich:datascroller>

<rich:dataTable id="prodClassificationOutputTable" border="0"
                width="100%" columnClasses="col" headerClass="column-header"
                style="overflow:auto;" rowClasses="odd,even" align="center"
                value="#{prodClassificationBean.outputClassificationWrappers}"
                var="prodClassificationRow" rows="100" rowKeyVar="row" immediate="true">
<!-- ... -->
<rich:dataTable>

I checked other solutions. I tried to implement page attribute for datascroller but it doesn't seem to be working. I created an attribute firstpage in backing bean being set to "1" when search happens so that page attribute of datascroller will have value as 1. But it's not resolving the issue.

I would like to know where I am going wrong.

I tried solutions from https://developer.jboss.org/thread/10566?start=0&tstart=0 but nothing is working — goyalshub1509, Jun 02 '16 at 17:47
1. This isn't an error. 2. You wrote that "nothing is working" from jboss forum, but you pasted here "an answer" which is the 3rd answer there. — Emil Sierżęga, Jun 03 '16 at 20:21

I was able to resolve the issue by myself. Here is what I did:

<rich:datascroller id="prodDataScroller" for="prodClassificationOutputTable"
                   rows="100" maxPages="10" fastStep="3" renderIfSinglePage="false"
                   binding="#{prodClassificationBean.scroller}">     
</rich:datascroller>
<rich:dataTable id="prodClassificationOutputTable" border="0" width="100%" 
                columnClasses="col" headerClass="column-header" 
                style="overflow:auto;" rowClasses="odd,even" align="center"
                value="#{prodClassificationBean.outputClassificationWrappers}"
                var="prodClassificationRow" rows="100" rowKeyVar="row" immediate="true">

    <rich:column align="center" width="20%">
        <f:facet name="header">
            <h:outputText value="ID" />
        </f:facet>
        <h:outputText style="font-weight:bold" value="#{prodClassificationRow.outputId}"/>
    </rich:column>

</rich:dataTable>

Among all, important to note is binding="#{prodClassificationBean.scroller}" in datascroller.

Now in the backing bean:

public class ProdClassificationBean {
    private transient HtmlDatascroller scroller; 
    //getter and setter for scroller

    // inside the action operation()
    if (scroller != null) {
        scroller.setPage("1");
    }
} // end of class
