Issue with graphics not being visible in multiple graphics layers

JonathanKressin — Thu, 02 Jun 2016 19:25:59 GMT

Hello,

I have a pretty solid JavaScript mapping application that I wrote several years ago. It is currently using the 3.3 api. I am moving forward in updating this to 3.16 so that we can get around issues we have been having lately with newer versions of IE.

One big problem I am seeing moving to the latest API is how graphics and graphics layers are being handled. I have a few different graphics layers for the different functionality in the application. Adding new graphics to these layers does not produce any errors, but is not displayed. Looking at the objects behind the scenes, the graphics are being added to the correct layers and everything is flagged as visible.

Trying different APIs, this problem appears to start happening at 3.11.

Does anyone have any ideas on what changed that would affect how graphics are displayed?

Thanks for any advice you can provide!

Sincerely,

Jonathan

(Here is my original app that works correctly at 3.3: Kenosha County Interactive Mapping )

Are you going to try to move to AMD?

I was really hoping I could stick with the legacy method of defining and consuming modules for now, as I have quite a few custom modules in my code. I don't have a lot of development time right now to rewrite the program, but was hoping I could at least get it working enough with the latest API to support the latest browsers.

Thanks!

Jonathan,

It's a timing issue. You need to be sure the nap is loaded before trying to add a GraphicsLayer to it:

dojo.connect(kctools.map, "onLoad", function () {
            // Setup Graphics Functionality
            grtool = new kcgis.Graphics(kctools.map, clearTools, kctools.srStateP);
            grtool.showDrawOptions("divDrawOptions");
            grtool.initializeButton("btnDrawPoint", "point");
            grtool.initializeButton("btnDrawLine", "line");
            grtool.initializeButton("btnDrawFreehandLine", "linefree");
            grtool.initializeButton("btnDrawShape", "polygon");
            grtool.initializeButton("btnDrawFreehand", "polyfree");
            //grtool.initializeButton("btnInsertImage", "image");
            grtool.initializeButton("btnInsertText", "text");
            grtool.initializeButton("btnEraseGraphic", "erase");
            grtool.initializeButton("btnClearGraphics", "clearall");
            layerlist.func_image_change = kctools.set_image_base;
            layerlist.initialize(dojo.byId("paneLayers"), kctools.map, master_layer_list, image_layers, kctools.feature_layerlist, kctools.imagebase, "layerlist");


            dojo.connect(kctools.map, "onUpdateEnd", function () { layerlist.onMapUpdate(); });
            dojo.connect(kctools.map, "onUpdateEnd", function () { updateScale(kctools.map.getScale()); });
            //dojo.connect(dojo.byId("chkOrthoToggle"), "onchange", toggleImagery);
            changeImagery("rdoImage2015");
            kctools.map.setScale(12000 * 12);
            //kctools.map.graphics.disableMouseEvents();
        });
