The server code reads the settings and builds a javascript object that it passes to a function on the browser that extracts the pieces it needs and constructs a map. This allows us to configure a site for different customers without having to modify the javascript.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The configuration object contains a map options object, an array of layer objects, and an array of control objects. Each layer object and control object contains a layer options object or a control options object.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>It’s been working fine, within its limits, but I just ran into something unexpected. We find for a customer we want to set OpenLayers.IMAGE_RELOAD_ATTEMPTS. And this isn’t an option on the map, or on any layer or control. It’s a global setting, independent of any map that might be constructed.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>It doesn’t look like it will be hard to retrofit into my scheme. I’ll simply have the javascript that handles the map settings object check to see if a setting is IMAGE_RELOAD_ATTEMPTS, and if it is, change the global setting.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>But my question is this: what other global settings of this sort are there?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>What map settings are available is documented in the map class’s source. Ditto for layers and controls. But OpenLayers.IMAGE_RELOAD_ATTEMPTS is just a variable in OpenLayers\Util.js. There’s another setting, next to it: OpenLayers.Util.onImageLoadErrorColor. But these aren’t part of a list of the global settings, they’re simply declarations near where they are used.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Are there other global settings of this sort, in the code? Are these documented anywhere? Is there any way of finding them, other than reading the entire codebase?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
