Hi,
I've just updated SolpartMenu to version 1.7 from http://www.solpart.com/Default.aspx?tabid=77&pid=2 to fix the randomly appearing 'Object reference not set..' error with previous version 1.6.x. Seems that this error is gone. Unfortunately I've found another issue introduced with version 1.7.

We have a 3-level drop down menu (menu bar, two levels of submenues below). If one clicks a menu item i the first sublevel (mention that this item has children), the child menu will not disappaer on clicking the item. A little patch would held (pls. excuse, if that idea seems to be more sofisticated... maybe someone will solve that problem in a more thoughtful way).

  //--- menuitem click ---//
 SolpartMenu.prototype.onMBIC = function (e, evt)
 {
     var oRow = spm_getSourceTR(e, this._m_sNSpace);  //event.srcElement
     var sID = oRow.id.substr(2);
     if (spm_itemHasChildren(sID, this._m_sNSpace) == false)
        this.hideAllMenus();

     this.fireEvent('onMenuItemClick', oRow);

     if (spm_getAttr(oRow, "menuclick", '').length)
     {
         eval(spm_getAttr(oRow, "menuclick", ''));
         this.hideAllMenus();
     }
     spm_stopEventBubbling(evt);
  
     this.handlembi_mo(oRow, true);
     // hide all child menus on click...
     this.hideAllMenus();

 }

Yours,

I am a little confused.  You are saying this issue was introduced in 1.7?

When you click the menu, are you not navigating to another page?

Could you provide a URL for me to look at and tell me the steps necessary to reporduce your issue?

That fix is not the ideal one.  There are many users that like to click a menu that has a submenu to show the submenu.  With your fix, this will cause the menu to disappear...   Looking at the code I see that there is an error with the spm_itemHasChildren function.

This change should fix it.
