Wwv_flow.accept: SIGNATURE (parameter names) MISMATCH

Question

Hi folks,
I'm getting an below error when submitting page:
wwv_flow.accept: SIGNATURE (parameter names) MISMATCH
VARIABLES IN FORM NOT IN PROCEDURE: P3_TEXAREA_TOM_REM
NON-DEFAULT VARIABLES IN PROCEDURE NOT IN FORM:
  DAD name: he
  PROCEDURE  : wwv_flow.accept
  URL        : http://url/pls/he/wwv_flow.accept
  PARAMETERS :
  ===========My page is only a test page, where I have only 1 item defined with below settings:
ITEM TYPE: TEXTAREA called "P3_TEXAREA_TOM"
In "Post Element Text" I've entered:
<div>
<input readonly type="text" name="P3_TEXAREA_TOM_REM" size="3" maxlength="3" value="100"> characters left
<br>
</div>Above was entered as a placer for counting available characters.
If above "Post Element Text" is cleared, page submits sucessfully.
Any idea how to fix it?
Thanks,

Hi Jari,
I have an additional task, where I'm trying to implement character count for this test text field, as standard one, seems to be not working properly, when you use a "return" character (as the carrige returns should be counted as 2) which later causes:
ORA-12899: value too large for column "QTEST"."TEST"."TEXTVAR100" (actual: 118, maximum: 100)while my textarea is restricted to 100 character only!
Here is my settings:
1 page item:
Name: P3_TEXAREA_TOM,
Type: TEXTAREA
Maximum Width: 100
HTML Form Element Attributes: onKeyDown="textCounter('P3_TEXAREA_TOM','P3_TEXAREA_TOM_REM',100)" onKeyUp="textCounter('P3_TEXAREA_TOM','P3_TEXAREA_TOM_REM',100)" onBlur="trim_field('P3_TEXAREA_TOM',100)" Post Element Text:
<div>
<input disabled type="text" name="P3_TEXAREA_TOM_REM" size="3" maxlength="4" value="100"> characters left
<br>
</div>Other properties for item are default.
Page header javascript:
<script type="text/javascript">
function trim(str, chars) {
     return ltrim(rtrim(str, chars), chars);
function ltrim(str, chars) {
     chars = chars || "\\s";
     return str.replace(new RegExp("^[" + chars + "]+", "g"), "");
function rtrim(str, chars) {
     chars = chars || "\\s";
     return str.replace(new RegExp("[" + chars + "]+$", "g"), "");
function trim_field(field_name, maxlimit) {
     <!-- alert(document.getElementById(field_name).value.length); -->
   document.getElementById(field_name).value = trim(document.getElementById(field_name).value);
     <!-- alert(document.getElementById(field_name).value.length); -->
   if (document.getElementById(field_name).value.length > maxlimit)
     document.getElementById(field_name).value = document.getElementById(field_name).value.substring(0, maxlimit);
     <!-- alert(document.getElementById(field_name).value.length); -->
function textCounter(field_name, cntfield_name, maxlimit) {
  l_field = document.getElementById(field_name);
  l_cntfield = document.getElementById(cntfield_name);
  if (l_field.value.length > maxlimit)
     // if too long...trim it!
     // first try to trim it
     l_field.value = trim(l_field.value);
     if (l_field.value.length > maxlimit)
        l_field.value = l_field.value.substring(0, maxlimit);
        alert('Maximum characters reached!');
     else
        l_cntfield.value = maxlimit - l_field.value.length;
     <!-- alert(l_field.value.length); -->
  // otherwise, update 'characters left' counter
  else
     l_cntfield.value = maxlimit - l_field.value.length;
</script>On page is also 1 submit button which inserts record into below table:
In database I have 1 test table:
create table test
( text        clob,
  textvar100  varchar2(100)
);Page Insert process (once SUBMIT button is pressed):
insert into test
( text,
  textvar100
values
( :P3_TEXAREA_TOM,
  :P3_TEXAREA_TOM
);If you enter string with length <= 100 characters then all works fine, except when you use few carriage returns.
Any idea how to fix this dodgy issue?
Thanks,
Tomas
