problem with openlayers update to 2.13.1

[luca marletta]

Hi all,

I update openlayers in a working Heron app to version 2.13.1 

and immediately start an error 

Creating Heron App from layout = panel Heron.js:148
Uncaught TypeError: Cannot read property 'maxExtent' of null

it seems related to this method in OL

/**

     * Method: shouldDraw

     * Return whether or not the tile should actually be (re-)drawn. The only

     * case where we *wouldn't* want to draw the tile is if the tile is outside

     * its layer's maxExtent

     * 

     * Returns:

     * {Boolean} Whether or not the tile should actually be drawn.

     */

    shouldDraw: function() {        

        var withinMaxExtent = false,

            maxExtent = this.layer.maxExtent;

        if (maxExtent) {

            var map = this.layer.map;

            var worldBounds = map.baseLayer.wrapDateLine && map.getMaxExtent();

            if (this.bounds.intersectsBounds(maxExtent, {inclusive: false, worldBounds: worldBounds})) {

                withinMaxExtent = true;

            }

        }

        

        return withinMaxExtent || this.layer.displayOutsideMaxExtent;

    },

but I normally set maxExtent and in previous OL worked well so what's changed and how fix?

I need to understand because this problem comes out also after close print panel even with old OL version

could anyone help?

thanks a lot

Hi Luca,

Upgrade from OL 2.12 to 2.13 is not trivial. I have planned an extra
issue for that, also since many OL 2.13 functions are in
override-openlayers.js.

We need funding for this as the following tasks need to be performed:

- revise all examples to include 2.13
- revise override-openlayers.js function by function
- retesting all examples and apps
- fixing bugs
- keeping Heron forward compatible with OL 2.12 e.g. in
override-openlayers.js

So I will at least open the issue. My cautious estimate is, that it will
take one or more days of development and testing. best,

Just

Thanks for info and replay Just.

I'll consider other options for now.

I use OL 2.13.1 in may Heron app, but I only had problems with IE tile rendering. You should try to build from OL master:

Hi Just and everybody else,

we had the same exception when upgrading Mapbender3 to OL2.13.1. Turned out we had to pass and explicit tileManager: null with the options for the OpenLayers.Layer.Map constructor. Maybe this will be of help if you haven't solved this one yet. Seems to be a problem with singleTiled WMS layers for us.

Cheers,
