Bug? WHY I can´t modify the values of controls INSIDE group if linked?

I want to use more the new groups in FF 4.0 but I found something that I do not understand and do not know if this is a bug or do not know why this happens.

It seems that Controls components values can't be dealt and modified inside groups when connected externally

The problem is that if you make a group and the components have controls sliders inside the group that have already controls sliders linked to them outside of the group, then you CAN´T modify and customize any of these controls sliders because the control slider that would let you modify it is missing.

You must connect the control slider outside of the group if you want that this control slider appears in the settings tab

I have made some screenshots to show graphically what I mean

Here is what can be seen outside of the group

And as you can see, inside the group there are more control components than the ones outside, so if you try to modify one of the control components that are NOT connected externally you can do it INSIDE the group

Color control unconnected externally does not allow to load any image ONLY plain colors can be used when INSIDE the group

BUT with color controls there is a ANOTHER added problem or bug more, and is that EVEN you have a color control INSIDE the group NOT connected externally (as it is shown on the first screenshot above) you CAN´T load any image in the color control from INSIDE the group as there is no way to active the "Allow Images" option, so you can ONLY change the color of the color control.

And there is something that also may be confusing when using the Image component externally connected to a group as this component is CONVERTED to an Color control component instead when INSIDE the group, but really this is NOT a color control and can´t be used as one, and so also you can´t modify any of the values of it when you are INSIDE the group

Please see below the next post after this one for the final conclusion and my thoughts about this bug/problem or whatever this is and wondering why this happens

TO BE ABLE TO TEST WHAT I AM TELLING WITH THIS FILTER ABOVE

I have made a filter to show what I am trying to explain

1 - Download filter attached at the end

2 - Edit filter in Filter Editor

3 - Go inside the group

4 - Try to modify any of the "H Range", "Mortar Width" or "Chaos" sliders and you will see that is NOT possible because the sliders are NOT showing in the left side

5 - Try modify the image input of the color controls INSIDE the group and you can´t do it, EVEN if the color control is NOT attached outside of the group.

6 - Now try to modify any of settings of "L Range", "Fill Mode" or "Circular Arc" and then now these settings APPEAR INSIDE the group at the left, but as said, this only happens if there is no external slider linked outside of the group

7 - Go outside of the group

8 - Go to "Filter Controls" under Result component to see the "Settings tab" at left and see that ONLY the sliders that are linked OUTSIDE of the group will be seen in the settings tab

9 - So the only way to make all the controls inside the groups appear ALSO in the settings tab in the filter you must connect EACH one of the sliders and color controls ALSO OUTSIDE of the group, BUT then after you can´t modify any of the settings from INSIDE the group.

10 - So if you really need to add also externally the sliders externally it seems that you must copy them from inside the group and paste them outside after, because you can´t go outside of the group and add a new slider because this slider will have DIFFERENT values than the sliders that is already inside and linked and connected to this external link.

11 - What I have seen is that YOU CAN modify the remapping of the slider EVEN if the slider is already connected to another slider outside of the group, so you can go to an internal slider and do the remapping and the external slider will follow the internal remapping

I'm going to assume this post is basically / about the same as your last post on the same subject. I briefly mentioned the reasoning.

Here's a thought: if 2 or more nodes / groups share a common variable then there's a chance you might throw off a bunch of other nodes without confirming that you're about to change properties of multiple nodes.

So I guess this is an hierarchy thing. It's basically brings into question whether you should have control over a variable from a subpatch which logically feels weird. FIY: most other programs like Quartz Composer (and many others) behave similarly. But I'm hardly against the idea of making life a bit easier. Just note: I'm no authority with this so what I'm saying above is just observation.

I have made another screenshot to show it more clearly

It seems that there is a BAD news coming from Vladimir Golovin (and Skybase also) as you can see in this thread here that confirms that all this above IS NOT A BUG, and is totally right and is really how it works and how is done by the developers.

So you are NOT able to modify the contents of a group from a filter that has the controls components outside of the group so they can be shown on the settings tab

So for example in this well done filter Image Knit by Sharandra it includes groups AND when entering the groups there is no possible way to modify any of the values of the components inside that have an external connection outside of the group WHILE you are inside the group because the controls for them are OUTSIDE of the group.
