I have added support for Dojo's IframeIO AJAX Transport to CForms in BRANCH_2_1_X. This is to allow forms with file upload fields to be able to be submitted via AJAX. This is implemented only for cforms that use JXMacro rendering pipelines.
I have tested this under Firefox, MSIE and Safari, AFAICS all samples that worked before the change still work. It is currently disabled in Safari as it does not work in the release version, however it does work in the nightly builds of Webkit, so hopefully it will work in Safari soon.
IframeIO and XMLHttp Transports do have some differences ..... XMLHttp is completely asynchronous, IframeIO is not. Submit events in IframeIO get queued by Dojo as it can only handle one submit and response at a time, as it uses a hidden iFrame for the form.
I had a great deal of trouble getting BrowserUpdate to work reliably across platform and browser. I eventually had to resort to placing the update content inside a <textarea> and parsing it on the client. It looks and sounds clunky but it was the only technique I could get to work reliably.
While reworking the CFormsForm Widget (etc.) I was able to remove some functions from the CForms Libs and use functions that come with Dojo instead that have the same behaviour.
Another change I have made is to disable the form-control that submits the form, re-enabling it when the Request returns, to try to avoid double submits etc.
These changes need more testing !!!!Please test Ajax and non-Ajax cforms, forms that use FormsTransformer as well as JXMacros. Please look out for form controls that do not get re-enabled after the Request has returned.
enjoy regards Jeremy
