How to remove a condition tag?

Edit 2022-06-25

Dear experts

I developed a script derived from Rick Quatro's excursus on Deleting Conditions.

→ Running the script does not remove the condition from the text.

Any ideas about this?

For easy testing my case you have here a complete script with no dependencies...

Use the test file on my website.

//@target framemaker
var KLD_Z = KLD_Z || {};                          // global script object

KLD_Z.RemoveConditionsFromText = function (oDoc, oTR, aRemoveConds) { // ======
/*            Get the list of properties and methods (functions) of an object
Arguments     oDoc            Current document
              oTR             TextRange of the found conditions
              aRemoveConds    Array of conditions (names) to be removed

*/
var oProps, asCondFmts, j;
  oProps = oDoc.GetTextPropVal (oTR.beg, Constants.FP_InCond);
  asCondFmts = oProps.propVal.osval;  // Get a list of the conditions
  if (asCondFmts.length === 0) {
      return; // No conditions are applied to the text range
  }
  for (j = 0; j < asCondFmts.length; j += 1) {
    if  (KLD_Z.IsInArray (aRemoveConds, asCondFmts[j].Name) != null) {
      Array.prototype.splice.call (asCondFmts, j, 1); // Remove from list.
    }
  }
//  Following condition is always false
  if (asCondFmts.length !== oProps.propVal.osval.length) {
    oProps.propVal.osval = asCondFmts; // apply updated list back to TR
    oDoc.SetTextPropVal (oTR, oProps);
  }
} // End RemoveConditionsFromText ---------------------------------------

KLD_Z.IsInArray = function (array, item) { //==========================
/*            Get index of item in array
Returns       Index of found item or null
*/
var j, jMax;
  jMax = array.length;
  for (j = 0; j < jMax; j++) {
    if (array [j] == item ) { return j;}
  }
  return null;                                    // not found in array
} //--- end IsInArray -------------------------------------------------

KLD_Z.GetFindParameters = function (sFType, sSearch) { //==============
// stripped down to the essentials for this test case
var findParms, jj, oPropVal1, oPropVal2;

  findParms = new PropVals();
  oPropVal1 = new PropVal() ; // ---------------- NoWrap
  oPropVal1.propIdent.num = Constants.FS_FindWrap ;
  oPropVal1.propVal.valType = Constants.FT_Integer;
  oPropVal1.propVal.ival = 0 ; // no wrap
  findParms.push(oPropVal1);

  oPropVal2 = new PropVal() ;
  if (sFType == "CONTAG") { // ------------------- Conditional tags
    oPropVal2.propIdent.num = Constants.FS_FindCondTextInCondTags;
    oPropVal2.propVal.valType = Constants.FT_Strings;
    oPropVal2.propVal.ssval[0] = sSearch;         // "cond1"
//  The following does not work in ES
//  for (jj = 0; jj < sSearch.length; jj++) { // ["cond1", "cond2", …]
//    oPropVal2.propVal.ssval[jj] = sSearch[jj];
//  }
  }
  findParms.push(oPropVal2);
return findParms;
} //---  end GetFindParameters ----------------------------------------

KLD_Z.main = function () { // <><><><><><><><><><><><><><><><><><><><><
var oDoc, oFindParms, oTR;
  oDoc=app.ActiveDoc;
  oTR = oDoc.TextSelection
// Create a text Selection of the conditional text
$.bp(true);
  oFindParms = KLD_Z.GetFindParameters ("CONTAG", "Comment");
  oTR = oDoc.Find(oTR.beg, oFindParms);
  oDoc.TextSelection = oTR;
  KLD_Z.RemoveConditionsFromText (oDoc,oTR, ["Comment"]);

KLD_Z.main ();
