Why does Firefox refresh page when using paging patch with XML data table?

Works fine in IE, but FF reloads the entire page on both Windows and Mac. Every time i try to go to another page (doesn't matter if its next, previous, first, or last) it displays the correct data for a split second, and then reloads the entire web page (resetting the xml data to the 'first' page).

i can't post an example yet because it's behind a corporate firewall - i will work up a public example if the solution is not already obvious to someone out there ...

the relevant JS is included below:

<script>
    
    
    //	create ActiveWidgets data model - XML-based table
    var table = new Active.XML.Table;
    
    //	create ActiveWidgets Grid javascript object
    var oGrid = new Active.Controls.Grid;
    
    
    table.setText = function(value, i, j){
        var node = this.getNode(i, j);
        node.text = value; 
    }

    
    
    
    
    
    
    // url returning xml        
    table.setURL("xml_users.php?mode=<? printvar($mode) ?>&searchfield=<? printvar($searchfield) ?>&searchterm=<? printvar($searchterm) ?>&securityid=<? echo $securityid ?>");
    
    
    
    //	start asyncronous data retrieval
    table.request();    

    
    //	define column labels
    var columns = ["ID", "Email", "First Name", "Last Name", "Inactive", "Created", "Last Modified"];
    
    var defaultResponse = table.response;



    
    table.response = function(table){
        defaultResponse.call(this, table);
                        
        // replace the built-in row model with the new one (defined in the patch)
        oGrid.setModel("row", new Active.Rows.Page);
        oGrid.setProperty("row/count", this.getCount());
        oGrid.setProperty("column/count", 7);        
        oGrid.setProperty("column/texts", columns);    
    
        
        
        // set page size
        oGrid.setProperty("row/pageSize", 17);            
        goToPage(0);
    }
    
    
    
    function goToPage(delta){            
        var rowCount = oGrid.getProperty("row/count");
        var count = oGrid.getProperty("row/pageCount");
        var number = oGrid.getProperty("row/pageNumber");
        number += delta;
        if (number < 0) {number = 0}
        if (number > count-1) {number = count-1}
        document.getElementById("pagelabel").innerHTML = "Page <b>" + (number + 1) + "</b> of <b>" + count + "</b>"
        document.getElementById("rowlabel").innerHTML = "Total Rows  <b>"+ rowCount +"</b>";
        oGrid.setProperty("row/pageNumber", number);
        oGrid.refresh();
    } 
    

    
    //	provide external model as a grid data source
    oGrid.setDataModel(table);
    
    
    // create formats
    var fstring = new Active.Formats.String;
    var fnumber = new Active.Formats.Number;
    var fdate = new Active.Formats.Date;
    fdate.setTextFormat("mm/dd/yyyy hh:mm");
    fdate.setDataFormat("RFC822");
    //fdate.setDataFormat("ISO8061");
    fnumber.setTextFormat("");


    //	set column formatting
    table.setFormats([fnumber, fstring, fstring, fstring, fstring, fdate, fdate]);
    
    

    // handle row actions
    oGrid.Handler_Edit = function(rowindex) {
        //alert(this.getDataProperty("value",rowindex,0));
        var uid = (this.getDataProperty("value",rowindex,0));
        if (uid > 0) {
            document.location = "user.php?securityid=<?=$securityid?>&mode=edit&id=" + uid;
        } else {
            alert("Please select a user.");
        }
    }
    
    
    oGrid.Handler_History = function(rowindex) {
        var uid = (this.getDataProperty("value",rowindex,0));
        if (uid > 0) {
            document.location = "userhistory.php?id=" + uid;
        } else {
            alert("Please select a user.");
        }
    }
    
    

    oGrid.RowColor_Inactive = function() {
        return (oGrid.getProperty("data/text", this.getRowProperty("index"), 4) == "inactive") ? "#EAEAEA" : "#FFFFFF";
    }
    
    oGrid.getTemplate("row").setStyle('background', oGrid.RowColor_Inactive); 
    
    
    // set double-click action handler
    oGrid.DoubleClickAction = function(src) {
        var row = src.getRowProperty("index");
        oGrid.Handler_Edit(row);
    }
    oGrid.getTemplate("row").setEvent("ondblclick", function(){this.action("DoubleClickAction")});
    oGrid.setAction("DoubleClickAction", oGrid.DoubleClickAction);
    
    
    
    

    // initially set selected row
    <? if (isset($theindex)) { ?>		
        oGrid.setProperty("selection/index", <?=$theindex?>);
    <? } ?>
    
    
    
    //	write grid html to the page
    document.write(oGrid);
    </script>

it does the same thing using the php-javascript model - Firefox forces a webpage refresh when trying to change grid 'pages'. ???

solved the problem - if the grid resides inside <form> tags, in Firefox it exhibits the weird page refresh behavior above. if the <form> tags are removed, everything is fine ...

OK, I understand - it is due to the button click triggering form submit, right?

That's right, Alex.
The html button tag has an attribute called type thas has 3 possible values: button, submit and reset.
According to the w3c recomendation, if you don't specify this attribute, the default is submit.
This is exactly what Firefox do, but Internet Explorer does not.
