Re: [Dynapi-Dev] Redrawing widget with new data

[Richard B. <ma...@ri...>]

I know loadpanel has it's faults, and a few bugs, but it should work fine
for your purposes.
Basically you should regard a "loaded" loadpanel as a Dynlayer, which has
content written to it with setHTML.
If you write the content of a whole examples.html file to a Dynlayer with
setHTML, you will indeed generate errors, if however you write something
which could be expected to be found in the body of your document to the
layer, that should work fine - EXCEPT, that script tags would seem to be
stripped.
It is possible to get the value of a variable loaded from an external file,
or you could use getHTML to load a comma delimitated string, which you could
parse to your form.

Check out Cameron_Hart_Examples, and Christopher_Go_Examples on my site
(although there seem to be some NS issues with these files, these should be
solved in the latest release (I hope))

Cheers,
Richard Bennett
