After updating to version 2.5.1, all items stopped being displayed in some tabs (they are empty).
After analyzing the problem, I found out that it was caused by a change in version 2.5.1. I don't know exactly what it is about, but it concerns attributes. Some cards display attributes and some do not. Those that do not display often have "empty" or "null" attributes. Adding one such attribute that has the value "empty" or "null" in the history causes the card to display nothing.
If I remove the entire "attributes" section, the card displays correctly, i.e. it shows the entity states (without attributes)

This is card correctly (wer 2.5.0)

This is card afrer ver 2.5.1

This is card after remove "attribute" section

Do you have errors in the console (F12 in your browser to access developper tools) ?

[kosmaluk]

No, i dont have errors in the console

[royto]

@kosmaluk can you try with version 2.5.2 ?

[kosmaluk]

2.5.2 the card based on the template sensor does not work - empty.
But the original sensor works

Template sensor

Oryginał last_notification sensor

[kosmaluk]

Template sensor in 2.5.0

[royto]

@kosmaluk can you test with version 2.5.3 ? It should fix the issue

[kosmaluk]

this version works, but why does it display empty and null attributes? the earlier version deleted them automatically, and now how to hide them?

[kosmaluk]

this change is unnecessary. It blows away the entire view of all the cards. Why would anyone need empty or null attributes?
I don't know how to hide it now, and even if it's possible, it's a lot of pointless work on many cards.
I've already tried it and it doesn't work for me:

hidden_state: - state: '*' attribute: - name: TextLines value: null

[kosmaluk]

if you solved error 112 (Jump down
The entity attribute is not displayed on the card, if its value is zero #112) the content shows that the author meant the value "zero" and not empty attributes or null.
Its 'idn' attribute has a value of 0, so I think this change goes too far

[il77781]

@kosmaluk, I'm sorry that solving my problem has created problems for you... I definitely didn't want that...

[kosmaluk]

@il77781 I think you should specify what you wanted to achieve - attribute from:

• value 0 (zero)
• null value
• empty (no value)
  The previous solution which hides the null and empty attributes automatically was correct.
  Let him @royto solve our problem

[il77781]

@kosmaluk, I was talking about displaying an attribute whose value is exactly zero (not null and not no value), as you wrote above...
Before that, it was like this: the attribute is not zero - it was displayed, as soon as it became zero - it disappeared from the card... It is important for me to see exactly the value of the attribute, and it does not matter whether it is zero or not - it is important to see it in any case.
Of course, if the attribute is null or empty (no value), I don't need to see it...
Probably, for some specific tasks it may be necessary to display attributes in the null or empty (no value) state - perhaps for these purposes it would be nice to leave the possibility of displaying them.

[kosmaluk]

@il77781
so I was right. You need an attribute that has a value - value 0 (zero).
So the thigh change is too far.
If it's supposed to stay that way, there should be a function to hide them.
I tried to hide according to the documentation but it doesn't work with null and empty

[il77781]

I hope @royto finds a way to fix the situation.

[kosmaluk]

I tested to hide these attributes but it doesn't work.
The "empty" value works, but hides the entire item, not just the attribute.
The value "null" shows a processing error and dumps the card.

[il77781]

Yes, it is unclear why the hidden_state does not work...

[kosmaluk]

the hiden_state function will not work for this because it hides the entire object and not the attribute itself.
@royto must limit this change for you only to the attribute value =0 (zero) and roll back the remaining changes.
Unless he finds another solution

[il77781]

@kosmaluk, do you want it to be like this: the attribute that you specified in the card settings should be displayed only if it is not null (none) and not empty (no value)? Right?

[kosmaluk]

@il77781 just like that

My card 2.5.0 (automaticaly hiden this state null and empty)

This is my card on 2.5.3

[royto]

I will release a new version later that hide null values

[il77781]

@kosmaluk, Yes, I understand you...
But I also don't need anything that is at odds with your requirements! After all, the value 0 is not null (none) and not empty (no value) - although, it seems to me, null (none) and empty (no value) are generally the same thing... But in any case, this does not correspond to the attribute state having the value 0...

[kosmaluk]

the empty attribute does not display anything but appears as an item.
attribute "null" displays the value "null".
@royto wrote that he would do it later.
Thanks

[il77781]

@kosmaluk, In your example, it turns out that empty is Mess_W and Mess_I? Don't you want to see them either?

[kosmaluk]

@il77781 Exactly. They weren't visible before this change and I wish they were

[royto]

version 2.5.4 hides attribute if value is null

[il77781]

For me 2.5.4 works as expected! Thank you, @royto!

[kosmaluk]

@royto for me it no longer shows "null" attributes, but still shows "empty" attributes.
Please correct this one more.
Thanks

[il77781]

Probably, the absolutely ideal case would be in which the visibility of attributes in one state or another could be selected in the card settings...

[kosmaluk]

@il77781 Such a function would need to have an opposite function to hide only the attribute for a specific state.
But I don't need any of those.
All I need is to restore the state from version 2.5.0, i.e. automatic hiding of attributes with the status "null" and "empty".
Basically, version 2.5.0 already fully satisfies me, but I don't want to exclude the possibility of new updates (and the current update is ruining my cards)

[royto]

version 2.5.5 hides attribute if value is empty

[kosmaluk]

Thank you @royto. Now everything works
