I am having a problem extending Timeline to handle variable bands,
variable event sources, and variable mashups using a URL variable to
pass a list of sources.
Similar to the religions.html example which has two "fixed" event
sources and separate bands for each source, however, I want to handle
the case of n number of bands each with its own source.
I have been successful at creating the bandInfos array of length n,
and creating n eventSources, and can verify that timeline.create()
does in fact create n bands. I can vary the number of bands at will
(using URL variable list).
The issue is that all of the event sources are all plotted together in
the n-th band. My intent is for there to be one source per band using
the embedded index of bandInfos as the discriminator to create a band
for each source.
At the top level in ts_define.js, the loadXML code looks like:
for (idx=0 ; (idx <nBands); idx++) {
var aFile = GetFromListAt(fileList,idx); // retrieves an xml
file from a list of filenames
var xmlFile = aFile.replace(/\\+/g,"/");
var EventSourceX = window['source' + idx]; // n eventsources were
previously defined at window[source1], window[source2],...
tl.loadXML(xmlFile, function(xml, url) {
EventSourceX.loadXML(xml, url); // this works for one
project,
but not for n projects
});
}
I have debugged down into the
Timeline.DurationEventPainter.prototype.paint = function() { .... code
call . I anticipated that one event source would be painted for each
pass through the for loop, but that's not what appears to be
happening.
I am using a version of Timeline that I downloaded from the MIT
website before the migration to google.code. Any clue to what am I
doing wrong or was there a code change/fix made after my version that
tweaked this part of the Timeline code?
Any assistance would be much appreciated,
HC
