hookMsgListener (method in module tri )

This function is called during the initialzation of tri.js and performs several housekeeping functions:

• Builds a windows message event listener with processing routines for standard messages and the abilty to recognize and schedule custom message event handlers
• Using this message event handler it loads and caches the templates from 'AppsBase.htm'.
• Using this message event handler it loads and caches the templates in the custom .HTM files tagged in section "cust-templates"

The messages are routed according to a prefix which is a string separated by a :. The handler is expected to be in oGBL.msgHandler[sPref] where sPref is the string before the :.

If no prefix exists they are assumed to be system messages which are processed in the following manner.

sys-close-pageThe Form Page has closed.

sys-get-templateForm Page requires a template. This message will be received in the primary page. Responds with sys-put-template which will be seen in secondary page. The message includes the requested template.
