ORA-20001: Invalid parsing schema for current workspace ID

Question

I recently upgraded Apex version from 4.0 to 4.2 successfully. Everything looks good except in one of the applications, I am running into
ORA-20001: Invalid parsing schema for current workspace ID ( see below for detailed debug info). It seems this page region code is still looking at
old apex scehma APEX_040000 instead of APEX_040200 somehow. Any ideas.
is_internal_error: true
apex_error_code: APEX.REGION.UNHANDLED_ERROR
ora_sqlcode: -20001
ora_sqlerrm: ORA-20001: Invalid parsing schema for current workspace ID
component.type: APEX_APPLICATION_PAGE_REGIONS
component.id: 21560330709310725
component.name: Calendar

Thanks Patrick. Just wanted to make you're referring to the below code. what package I would be using instead of 'wwv_render_calendar2.show'
wwv_render_calendar2.show (
p_query => q,
p_max_rows => '5',
p_heading_bgcolor => '#CCCC99',
p_table_bgcolor => 'WHITE',
p_monday_friday_only => 'NO',
p_non_curr_month_attr => 'bgcolor="#F7F7E7"',
p_month_font_face => 'Arial',
p_month_font_size => '+1',
p_month_font_color => 'BLUE',
p_day_font_face => 'Arial',
p_day_font_size => '+1',
p_day_font_color => 'BLACK',
p_cell_font_face => 'Arial',
p_cell_font_size => '-2',
p_cell_font_color => 'BLACK',
p_page_width => '95%',
p_show_month_above_tab => 'YES',
p_min_blank_cell_height => '45',
p_calendar_day_date_fmt => 'MM/DD/YYYY',
p_cur_local_date => '');
end;
