Function not recognised when working via menu

[K.Daube]

Dear all,

My script for document navigation works fine as long as I do not use it via menu. Via menu the main function is not found:

Error Message      : KLD_E.DocNav is not a function
Script, Line#   : C:\Users\klaus\AppData\Roaming\Adobe\FrameMaker\15\startup\ETBdocNav.jsx,  85

I can not find, why the function is not defined. I have changed the location of it withing the script (before the menu set-up, after it) - to no positive effect.

Any ideas?

KLD_E.DocNavMenu = function (){ // === Create menu entry ================
var menuLocation, oCmd = {};

// ---------------- Menu and Command definition for documents -------
  menuLocation  = app.GetNamedMenu("ViewMenu"); 
  oCmd.MenuDnav = menuLocation.DefineAndAddCommand (1,"ETBdocNav",  localize (KLD_E.sDnav_title), "\\!qdn");
  oCmd.MenuDnav.KeyboardShortcutLabel = "ESC q d n";  
  UpdateMenus();
} // --- end KLD_E.DocNavMenu

function Command(cmd) { // ==============================================
	switch(cmd)  {	                  // Respond to menu command.
		case 1: 
      KLD_E.DocNav();
      break;
    }
} // --- end Command

KLD_E.DocNav  = function (location, bTag)  { // === Main function =======
// Arguments  location       Current screen location of palette. used for resize
// Called by  -
// Calling    KLD_E.BuildPalette, KLD_E.GetParagraphs
// Comment    To be implemented in ETBdocNav

var aPgfs = [], oDoc, wDocNav;

  if (bTag === undefined) {bTag = false};
  oDoc = app.ActiveDoc;
  if (!oDoc.ObjectValid()) {
    Alert (localize (KLD_E.sDnav_docRequ), localize (KLD_E.sDnav_title), true);
    return;
  }
  if (!KLD_E.GetLevelSettings(KLD_E.oLevelSettings)) {return;};
  KLD_E.GetParagraphs (oDoc, aPgfs, KLD_E.oLevelSettings);
  wDocNav = KLD_E.BuildPalette (oDoc, aPgfs, KLD_E.oLevelSettings, bTag); 
  if (location) {
    wDocNav.bounds = location;  // Restore the palette's previous size and location on the screen.
  }
} // end of KLD_E.DocNav

Strange things happen withem.

At the very end of the script file I have these statements:

Console ("KLD_E.DocNav is "     + typeof KLD_E.DocNav);
Console ("KLD_E.DocNavMenu is " + typeof KLD_E.DocNavMenu);
KLD_E.DocNavMenu ();                              // comment for debug without menu
//KLD_E.DocNav ();                                // uncomment for debug without menu

Before this all functions are defined. During start the first Console statement is executed and delivers

KLD_E.DocNav is function
KLD_E.DocNavMenu is function

There is a menu item established - hence I can issue the function.

When issuing the shortcut ESC q d n or select the menu I get in the console

Error Message      : KLD_E.DocNav is not a function
Script, Line#   : C:\Users\klaus\AppData\Roaming\Adobe\FrameMaker\15\startup\ETBdocNav.jsx,  514

So at some time the type of the function is ruined - but how?

Solved - see end of post

Script behaves differently in Startup and in the …\Adobe Scripts folder

I have added a log instruction just before the execution in the Command function - and there is aleady one just befor calling the main function (see above).

function Command(cmd) { // ==========================================
	switch(cmd)  {	                        // Respond to menu command.
		case 1: 
Console ("Command - KLD_E.DocNav is "     + typeof KLD_E.DocNav);
      KLD_E.DocNav ();
      break;
    }
} // --- end Command

…\Adobe Scriptsfolder - other scripts (Startup) using the global object KLD_E

Running the script: the menu is established and the log confirms that KLD_E.DocNav is function.

Execute the script via menu: It runs and the log in the Command function also confirms that KLD_E.DocNav is function.

→ In this environement (started from the …\Adobe Scripts folder) the scripts works correctly.

Startup folder - no other scripts using the global object KLD_E

The script established the menu and the log confirms that KLD_E.DocNav is function.

Execute the script via menu: It runs and the log in the Command function also confirms that KLD_E.DocNav is function.

→ The script runs correctly also from the Startup folder, if there are no other scripts using the global object KLD_E.

Startup folder - with other scripts (Startup) using the global object KLD_E

→ This logs on execution from the menu: Command - KLD_E.DocNav is undefined

Conclusion

Error in using global object KLD_E. Replace

KLD_E = {};

by

if (typeof KLD_E == "undefined") {
  KLD_E = {};            // Global object may already be defined by others
}

 ... and everything works as expected!
