[Building Sakai] Reload Top Navigation Menu

[Steve Swinsburg]

Wrapping the call in a try/catch should be done for any call to the parent or window javascript object, for example resizing the iframe, since an LTI call won’t have access to that due to the browser restrictions, as you mentioned.

I’m surprised we don’t see more Javascript issues when tools are rendered externally to Sakai via LTI. 
Here are two Jiras that worked through it:

https://jira.sakaiproject.org/browse/PRFL-672
https://jira.sakaiproject.org/browse/CLOG-108

cheers,
Steve

Programmatically, after I make changes in a module and go to the next page, how would I go about programmatically reloading the whole page, like pressing F5? I make changes to the top menu, from within a customized tool, and would like to not reload the tool frame, but the whole window.

Sometimes the portal servlet, SkinnableCharon or whatever, will pick up the vm changes without a reload, but you often have to restart the webapp in the manager. Otherwise, a mvn -o clean install sakai:deploy in the portal project will deploy all the changes to code in vms, js or java.
