dojo namespace change upsets loading of local modules

LorenMueller — Thu, 19 Aug 2010 00:48:44 GMT

Hi,
I can't get local modules to reload anymore with the namespace change. In the code below I can not get into init_2 (I get cross-domain loading errors), though the in-line dijit is created just fine. Hoping you can see where I have gone wrong without having to create your own test utility resource to try this one out.

It's probably just a typo but thought I'd check just in case, in the code snippet below it looks like there's a space in Utility?

esriDojo.require("MyModules.Utilities.MyTestUtilit y");

Re: dojo namespace change upsets loading of local modules

Hi Kelly,
Yes, that was just a typo as I prepared my sample code for posting here. My modules have different names and I put that there as example of my structure.
Other than the typo, any other ideas about the module mapping and why the local ones will not load?
Thanks, Loren

Loren, it must have something to do with what is in MyModules.Utilities.MyTestUtility. I don't have access to that but when I remark that out everything seems to work fine.

We had to load a second version of dojo to get comet working, and at first we attempted to rename the esri dojo packages. Unfortunately, that was not easily done, so we renamed the second version of dojo. This worked out well.

My suspicion is that it has to do with the path in modulePaths. Where does "./MyModules" point to? If I understand how namespace changes work in dojo (which I may not completely) ./ may refer to something on ESRI's servers, not on your server. The namespace rename will point to wherever the dojo version is hosted, and in this case, it points to ESRI's server. Try putting in a absolute URL and see if that clears it up.

[EDIT]

If you're attempting to load something on ESRI's servers, you would get a cross site scripting error, so this makes a lot of sense. The xss error may be coming from the require call.
