LazyLoad chartdata with <$echarts $text={{LazyLoadExampleOfTextData}}/>
I have 15,380 ChartData tiddlers that originally were type application/javascript
that I realized didn't need to be marked because they are static charts generated upstream in python. I was hoping to take advantage of my currently lazyload configuration and reduce the 100mb initial size back down to <10mb.
However, the widget <$echarts $text={{LazyLoadExampleOfTextData}}/>
doesn't appear to handle lazyloading of the tiddlers.
errors thrown:
TypeError: this.getAttribute(...) is null
TypeError: parent is undefined
Is there a way to handle lazyloading of the ChartData tiddlers to the $echart widget?
Believe this is fixed on TW side. Need to update my server to test.

$text widget now works with lazyload tiddlers latest github master, but the macro still fails. Instead of a pop up error as before I now get an error in place of the chart.
In widget.ts
:
I see $tw.wiki.getTiddler(this.tiddlerTitle)
called on type === 'text/vnd.tiddlywiki'
while $tw.wiki.getTiddlerText(this.tiddlerTitle)
is called on type === 'application/json'
if a text/vnd.tiddlywiki
tiddler is tiddler.fields._is_skinny
then $tw.wiki.getTiddler
only returns the skinny fields.
$tw.wiki.getTiddlerText
would trigger a load of the full tiddler text. Is this why lazy loaded tiddlers are failing with <$echarts $text={{LazyLoadExampleOfTextData}}/>
I reverted back to v0.0.9 and no longer have issues lazyloading of the text/vnd.tiddlywiki
tiddlers for chart data.
Not sure what all I lost from the current release, However I reduced initial load size from 70+mb uncompressed to 7mb.
I tried to add lazy loading support for $tiddler as well in 0.2.5, the macro issue is still being troubleshooted : )
