slight bulletproofing of dojo button disable/enable code

[guest]

I would like to suggest a small bulletproofing of the code to enable/disable the button widget. Both references are to Button.js, version 0.4.1, in the routine _sizeMyselfHelper:

1) Line 107:

Replace:

				dojo.html.prependClass(this.domNode, "dojoButtonDisabled");

With:

				if (!dojo.html.hasClass(this.domNode, "dojoButtonDisabled")) {
					dojo.html.prependClass(this.domNode, "dojoButtonDisabled");
				}

2) Line 111: Replace:

				dojo.html.removeClass(this.domNode, "dojoButtonDisabled");

With:

				if (dojo.html.hasClass(this.domNode, "dojoButtonDisabled")) {
					dojo.html.removeClass(this.domNode, "dojoButtonDisabled");
				}

Should the above be incorporated, I authorize anyone to do anything they wish with this enhancement, under the auspices of the dojo license. If I need to have a signed CLA, please let me know how to obtain one.

Thanks very much for the consideration,

Dave B.

I forgot to do this again (see 2399). My full name is Dave Barndt, and my e-mail address is: webservant@… . Thanks!

FYI, a signed CLA is now on file with the Dojo Foundation and I predated it with a date from before I submitted this suggestion.

The Button widget was rewritten for 0.9 and the referenced code no longer exists. The change will not be backported to 0.4.x.
