netzkeBulkExecute does not work properly on IE8

[Daniel David]

This solves the issue with empty arguments passed to apply function.

(see https://github.com/netzke/netzke-core/pull/62 for further details)

/netzke-core-0.10.0.rc2/javascripts/base.js

  netzkeBulkExecute : function(instructions){

    if (Ext.isArray(instructions)) {

      Ext.each(instructions, function(instruction){ this.netzkeBulkExecute(instruction)}, this);

    } else {

      for (var instr in instructions) {

        var args = instructions[instr];

        if(args instanceof Object && (Ext.Object.getSize(args)==0))

          args = [];

        if (Ext.isFunction(this[instr])) {

          // Executing the method.

          this[instr].apply(this, args);

        } else {

          var childComponent = this.netzkeGetComponent(instr);

          if (childComponent) {

            childComponent.netzkeBulkExecute(args);

          } else if (Ext.isArray(args)) { // only consider those calls that have arguments wrapped in an array; the only (probably) case when they are not, is with 'success' property set to true in a non-ajax form submit - silently ignore that

            throw "Netzke: Unknown method or child component '" + instr + "' in component '" + this.id + "'"

          }

        }

      }

    }
