Unable to select multiple files using input type file

[anku94]

Hi

I'm unable to use the File Upload dialog to select multiple files in MacGap using the following HTML5 element.

<input type="file" multiple="multiple">

This works fine in my Safari (and is supposed to be fully supported since Safari 5.0)

User Agent in my MacGap:

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_4) AppleWebKit/600.7.12 (KHTML, like Gecko) MacGap

(The same issue persists across both MacGap1 and MacGap2 - I also created the same issue for MacGap1)

So I dug into the MacGap code, and it seems that the Open Dialog Box behavior is described within runOpenPanelForFileButtonWithResultListener in Classes/WebViewDelegate.m

It does provide a parameter allowMultipleFiles which should be passed as a parameter to openDlg.setAllowsMultipleSelection but isn't. That's a bug, right?

If you pass true to allowMultipleFiles then the dialog will always allow multiple right? i.e. it still won't honour the multiple="multiple" part of the input tag. If you're able to get it doing that, it would be great!

No, you misunderstand me. allowMultipleFiles is an argument to runOpenPanelForFileButtonWithResultListener. It seems webkit parses the HTML source and sets the flag to true if multiple=multiple is there, and false if it's not. We just need to forward that flag to openDlg.

I was just confused why this has not been done already. It's a trivial one-liner, and I wondered if it might have anything to do with compatibility issues.

Sorry about that! My guess it's just an oversight. Could you make a pull request for this?
