Hi,
My current project involves a UI which is very similar to
that of a typical mail client (Outlook, Thunderbird etc.). In other words, our
screen is split into a “list pane” (upper half) and a “preview
pane” (bottom half) where each pane is actually just an HTML div.
Whenever the user selects one of the items in the list pane, we have to
asynchronously retrieve the summary data for that item and display it in the
preview pane.
In this architecture, we are using OPS for rendering the
preview data only. Everything else, including the ajax request made by the upper pane, is implemented
using Dojo (http://dojotoolkit.org/). So, a typical scenario runs like this:
1) User selects
an element in the list pane.
2) The
selection event triggers Dojo to make an ajax
call to a WebWork action.
3) The action forwards
to an OPS page flow url.
4) The html+css+js
content that is generated by OPS for the above page flow is sent back to the
client as the ajax
response.
5) Dojo parses
the received html content. In this process it does the following:
a. Picks up all
the <style …> and <script …> tags found in the response
and moves them to the top of the containing page.
b. Picks up the
contents of the <body> tag and inserts them into the “preview pane”
div.
Note: Steps (a) and (b) are needed because the response
itself is a complete HTML page and cannot hence be directly included within another
(parent) html page.
Now that the story is over, here is the crib ;-). With this
in place, we are seeing that the preview pane is getting rendered fine but none
of the javascripts are working. So, for example, I am able to see a calendar
control but on clicking it nothing happens (not even any errors). Just to make
sure that this is not a Dojo issue, we even hard coded all the ops styles and
javascripts in the parent document. Still no luck!
My assumption is that OPS relies on “window.onload”
events for proper initialization of its javascripts and hence without them
being called, things are going south. Am I right by any chance?
This issue is really haunting us, so any help/suggestions would
really be appreciated.
Thx & Rgds,
Vikas
