On Screen Totals not being updated (fyi)

I found that the on-screen totals were not being updated during the registration process.

Investigation showed that the correct values were in fact contained in the page source; however, the visual image did not reflect them.

Further investigation showed that the JSON object being returned from the AJAX call (events_planner_do_ajax) contains a lot more than just the html which the calling routine expects.

Resolution took three steps:

1) Access the JSON object and get the value associated with the key “responseText”.
2) Extract the embedded contents of the “html” key which the app expects.
3) Parse the text string associated with the “html” key stripping out all of the escape characters.

At that point the appropriate on-screen display can be generated.

I wasn’t able to find the root cause but a guess might be that it is related to the fact that I am using iThemes Builder for screen layouts.
