#10260 closed Bug (fixed)

ACF blocks tabSpaces

Reported by: Jakub Ś Owned by: Olek Nowodziński
Priority: Normal Milestone: CKEditor 4.1.1

Description

Seems Allowed Content Filter blocks http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-tabSpaces. Tab key causes focus on next element instead of inserting spaces into content area.

The below will not work without allowedContent: true

var editor = CKEDITOR.replace( 'editor1', {
	tabSpaces : 4,
	//allowedContent: true				
} );

ACF does not pass <span data-cke-marker="1"> element which editable#insertHtml uses (https://github.com/ckeditor/ckeditor-dev/blob/master/core/editable.js#L1127) to surround spaces when processing data.

I found that ACF also does not pass bookmarks (<span data-cke-bookmark="1" style="display:none;">&nbsp;</span>) and who knows how many other elements that we may need to sometimes insert to the editor.

So a basic solution would be to extend ACF with this kind of rule (this should be placed in filter constructor, next to default rule for p/br/div):

this.allow( {
	span: {
		match: function( el ) {
			return Object.keys( el.attributes ).some( function( attr ) {
				return attr.indexOf( 'data-cke-' ) > -1;
			} );
		},
		styles: 'display'
	}
}, 'default', 1 );

(Note: we don't need to specify data-cke-* attributes, because they all are passed by default)

However:

  • We will allow these spans in data outputted from editor (on the other hand we already allow data-cke-* attributes on all elements). So... if you agree that we shouldn't allow them for both - output and input, then this rule has to be implemented internally, inside filter. Note that CKEDITOR.filter#applyTo has 2nd argument which tells in which direction data is processed. The correct place for this rule will be around these lines - https://github.com/ckeditor/ckeditor-dev/blob/master/core/filter.js#L281-L288

This approach has another advantage - we will not expose in filter.allowedContent rule which is fully internal.

  • We haven't caught this issue before, because tests for editable#insertXXX are done with disabled ACF. I think that this case proved that we should enable ACF in those tests by setting minimum config.allowedContent that they need.

I'm for keeping stuff like this internally and as simple as possible. Thus I created branch t/10260 (+tests) with a fix for the issue inside of CKEDITOR.filter#applyTo.

Fixes also #10302.

I rebased and pushed both branches. Additionally - I pushed more tests and it turned out that t/10260@dev does not pass one of test cases. Filter should not accept CKE's stuff in output.

Updated both t/10260@dev and t/10260@tests.

I restricted the "holy cow mode" for data-cke-* spans to dataProcessor.toHtml() only as we don't want them on output. I also fixed some new test cases since dataProcessor.toDataFormat() avoids filtering, so switching tests to basic filter.applyTo() was necessary.
