Bug:accessing tab after creating array called tasks

[chrisboesing]

Found a little problem while programming
I have created an array called "tasks" inside of a transformResponse of a RestDataSource which will create some htmlpanes in a tab, when I want to access this tab I get following message from firebug:
_1.$kk is not a function
file:/C:/xampp/tomcat/webapps/smart/isomorphic/system/modules/ISC_Core.js
Line 2510

when I give the array a different name like foo, it works perfekt.

I have tried it in Firefox 3 and ie6

here is my code:

isc.RestDataSource.create({
    ID:"DSTasks",
    fields:{
        id:{title:"id", name:"id", hidden:true},
        name:{title:"Bezeichnung", name:"name"},
        added:{title:"hinzugefügt", name:"added"},
        due:{title:"fällig am ", name:"due"},
        status:{title:"status", name:"status"}
        },
    dataFormat:"json",
    dataURL:"test2.json",
    transformResponse : function (dsResponse, dsRequest, jsonData) {
        rows = isc.XMLTools.selectObjects(jsonData, "/response/rows");
		tasks=new Array(rows);
		notes=new Array(rows);
		assigned=new Array(rows);
		dates=new Array(rows);
		for (u=0; u<=rows; u++) {
			tasks[u-1]=isc.XMLTools.selectObjects(jsonData, "/response/data/"+u+"/tasks");
			notes[u-1]=isc.XMLTools.selectObjects(jsonData, "/response/data/"+u+"/note");
			assigned[u-1]=isc.XMLTools.selectObjects(jsonData, "/response/data/"+u+"/assigned");
			dates[u-1]=isc.XMLTools.selectObjects(jsonData, "/response/data/"+u+"/date");
		}
		drawTasks();
	}
})
isc.DynamicForm.create({
        ID:"FormSearch",
        canFocus:true,
        fields:[
            {name:"search", title:"Suche", canFocus:true,type:"text",keyUp: 
			function() {
				var bla=FormSearch.getValue("search");
				for(i=0;i<tasks.length;i++){
					if(bla>"")  {
						if(tasks[i].toString().toLowerCase().search(bla.toLowerCase())>0 ) {
							VlTasks.getMember("pane"+tasks[i]).show();
						}	 
						if(tasks[i].toString().toLowerCase().search(bla.toLowerCase())<0  ) {
							VlTasks.getMember("pane"+tasks[i]).hide();
						}		 
					}else {
						VlTasks.getMember("pane"+tasks[i]).show();
					}
				}
				
			}
		},
        ]
})

isc.VLayout.create({
    ID:"VlTasks",
    padding:20
})
isc.HLayout.create({
    ID:"HlTasks",
    members:[FormSearch,VlTasks]
})
isc.HTMLPane.create({
    ID:"functions",
    contents:"<a href=\"javascript:DSTasks.fetchData()\">laden</a>"
})
isc.TabSet.create({
    ID:"TabSetProjects",
    width:"100%",
    height:"100%",
    tabs:[
        {ID:"overview", title:"Übersicht",pane:functions},
        {ID:"tasks", title:"Aufgaben", pane:HlTasks},
        {ID:"milestones", title:"Meilensteine"},
        {ID:"files", title:"Dateien"},
        {ID:"messages", title:"Nachrichten"}
    ]
    
})
function drawTasks() {
	for(var z=0; z<tasks.length;z++)
	{
		var panename="pane"+tasks[z];
		VlTasks.addMember(
            isc.HTMLPane.create({
                ID:panename,
                width:"100%",
                height:40,
                overflow:"hidden",
                animateTime:200,
                border:"1px solid black",
                contents:"<div id=\"test\"><a href=\"javascript:changeStatus("+panename+")>"+tasks[z]+"</a></div><br> zugeteilt: "+assigned[z]+" fällig am: "+dates[z]
            })
        );
        if(u!=tasks.length){
            VlTasks.addMember(
                isc.HTMLPane.create({
                width:"100%",
                height:10,
                overflow:"hidden"
                    })
                );  
            }
	}
}

Hit "laden" in the first tab and then go to the second called "Aufgaben"

PS:Please release 7.0 before trying to fix this ;-)

Hi Chris,

If you've definitely tracked this down to the variable having the name "tasks", then I suspect some browser toolbar or similar Firefox extension you are using has created a global variable called that - SmartClient has no "tasks" variable and the code is run through a scanner that ensures that globals are never created.

Because of this kind of issue we recommend putting all your globals on a global "application object" instead of directly in global scope. For example:

window.myApp = isc.Class.create();
myApp.tasks = [ ... ];

Well, i have tracked it down to this variable and it doesn't work in firefox AND internet explorer. I don't have any extensions or toolbars in ie.

Thanks for your advice with the object, will use this instead

Hmm, tried out your code, but no luck reproducing the error. It's a mystery what's different about your system (maybe some kind pre-installed utility on your machine that includes browser plugins), but, that practice of keeping your globals on an "application object" will avoid this and any similar globals collisions.
