patch for refreshGroupSummary

[senordhuff]

Hi, I had to create a patch for v8.2. A call to recalculateSummaries() before the grid was drawn was throwing an error.

See below

		//added null check on this.body
		isc.ListGrid.getPrototype().addProperties({

			refreshGroupSummary:function(_1){
				
				if(!this.isGrouped || !this.showGroupSummary|| !this.groupTree) return; 
				
				if( this.showGroupSummaryInHeader){ 
					if (_1!=null ){ 
						var _2=this.groupTree.getParent( this.groupTree.get(_1)); 
						this.applyGroupSummaryToHeader(_2); 
						this.refreshRow( this.groupTree.indexOf(_2))
					} else{ 
						var _3=this.groupTree.findAll("$52e" , true); 
						for( var  i=0;i<_3.length;i++){
							this.applyGroupSummaryToHeader(_3[i])
						}
						this.markForRedraw("refresh group summaries" )
					}
				}else{ 
					var _5;
					if (_1!=null )_5= this.groupTree.getLength(); 
					this.groupTree.$736(); 
					if (_1==null ||(_5!= this.groupTree.getLength())){ 
						//added null check here
						if(this.body!=null){
							this.body.markForRedraw( "refresh group summaries")						
						}
					} else{ 
						var _6=this.groupTree.getParent( this.groupTree.get(_1)); 
						if(_6){ 
							var _7=this.groupTree.indexOf(_6),_8= this.groupTree.getChildren(_6); 
							for( var i=0;i<_8.length;i++){
								if (_8[i].isGroupSummary) this.refreshRow(_7+1+i)
							}
						}
					}
				}
			
			}
			
		}
		)

Thanks for the heads-up - we'll be incorporating this into our code-base in the near future.
