[ajaxform] Form submit stops working in IE7 after initial ajax file upload

[ajaxform] Form submit stops working in IE7 after initial ajax file upload

jQuery 1.4.2
jQuery Form Plugin 2.43
Internet Explorer 7.0.6001.18000

I am working on a web application to handle ajax file uploads via ajax using the jquery ajaxform plugin.

The workflow:
1 - User Uploads Image via form
2 - If successful, the form for the next step is returned and replaces the initial form. (This works fine)
   - If there is an error, the same initial form is returned with additional error messages.

The problem I am experiencing occurs when the initial form upload has an error and has to be redisplayed so the user can re-upload an image. In ff2 and chrome, this works fine but in IE7, the form is properly re-displayed but the form submit button no longer works. When clicked or submitted by pressing enter on a text field, the form does nothing. No ajax submit or the default submit.

My form markup looks like:
  1. <form enctype="multipart/form-data" class="uploadCompanyLogo" id="uploadCompanyLogo" method="post" action="/uploadcompanylogo">
    <label for="company_logo_file" tag="" class="required">Select a file</label>
    <input name="MAX_FILE_SIZE" value="104857600" id="MAX_FILE_SIZE" type="hidden">
    <input name="UPLOAD_IDENTIFIER" value="4bedc66305ed4" id="progress_key" type="hidden">
    <input name="company_logo_file" id="company_logo_file" type="file"><input value="Click to Upload" type="submit">
    <span id="uploadCompanyLogoFormAjaxLoading" style="display: none;">
    <img src="/static/images/ajax-loader_00000_FFFFF.gif">
    </span>
    </form>







My two jquery snippets I have tried look like:
  1. function initUploadCompanyLogo() {

  3.     $("#accordion").find("div:first").find("form").ajaxForm({
            data: {format: "html"},
            beforeSubmit: function(formData, jqForm, options) {
                $("#uploadCompanyLogoFormAjaxLoading").show();
                return true;
            },
            success: function(responseText) {
                $("#accordion").find("div:first").html(responseText);                        






  4.              initUploadCompanyLogo();
            },
            error: function(){
                alert("error");
            }
        });    




  5. }

and

  1. $(".uploadCompanyLogo").live("submit", function(){

        $(this).ajaxSubmit({
            data: {format: "html"},
            beforeSubmit: function(formData, jqForm, options) {
                $("#uploadCompanyLogoFormAjaxLoading").show();
                return true;
            },
            success: function(responseText) {
                $("#accordion").find("div:first").html(responseText);
            },
            error: function(){
                alert("error");
            }
        });

        return false;

    });


















Has anyone experienced this problem?
