[tree] Long label (with parentheses?) is not loaded, and prevents all labels from loading, subtree of its item is not created.

[aleksejrs]

• Single item: https://tools.wmflabs.org/wikidata-todo/tree.html?q=26842995&rp=279
• Its parent's tree: https://tools.wmflabs.org/wikidata-todo/tree.html?q=185217&rp=279&lang=ru

The item is simply:

• Label: "Молоко (кроме сырого). Продукты молочные и молочные составные, кроме масла из коровьего молока, пасты масляной, сыра, сырных продуктов и молочного жира"
• Description: "группа продукции в ОКП (92 2200)"
• subclass of: Q185217

[aleksejrs]

I moved the label to an alias for now, leaving an ellipsis in the long part.

[aleksejrs]

Label length is not all: no subtree is generated for the item. https://tools.wmflabs.org/wikidata-todo/tree.html?q=26842995&rp=279,31&lang=ru

[aleksejrs]

https://tools.wmflabs.org/wikidata-todo/tree.html?q=26842995&rp=279 (same with &lang=ru) shows the item itself, but nothing under it, although it has subclasses.

[aleksejrs]

It looks like data is updated rarely?

[Magnus Manske]

I switched the data source from WDQ to SPARQL, which has the latest data. Could you please

• check that results still make sense
• check if there are any of the above issues still present
• link to them and not fix them on Wikidata, so I can see how it actually goes wrong

[aleksejrs]

• Data has been updating much faster today (when I file the issue, it was maybe once in a few hours).
• I just put the long label back in https://www.wikidata.org/wiki/Q26842995 , and labels immediately stopped loading at https://tools.wmflabs.org/wikidata-todo/tree.html?q=26842995&rp=279

[aleksejrs]

I gave the same value "Молоко (кроме сырого). Продукты молочные и молочные составные, кроме масла из коровьего молока, пасты масляной, сыра, сырных продуктов и молочного жира" to the Esperanto label of the sandbox item https://www.wikidata.org/wiki/Q4115189 , and https://tools.wmflabs.org/wikidata-todo/tree.html?q=4115189&rp=279&lang=eo stopped showing labels that it did show just before.

[aleksejrs]

Please check if you can test it without me having set the label, because that first tree is linked to from https://www.wikidata.org/wiki/Wikidata:WikiProject_Food (the item is in the food tree), and I am using it to create items from a classification.

[Magnus Manske]

It was a problem with the PHP json_encode function confronted with HTML entities. Should be fixed now.

[aleksejrs]

Is it intended that the long label is not displayed at all now?

(One of the item's children is labelled "Curd snack" at https://tools.wmflabs.org/wikidata-todo/tree.html?q=185217&rp=279,31&lang=en )

[Magnus Manske]

It's https://www.wikidata.org/wiki/Q26842995 and it is weird in the database, as having two ru labels, which shouldn't be possible. I patched some code so that it at least shows as the Q number.

[aleksejrs]

Hm, maybe it is actually impossible to add it as a property value (and I renamed it because of this tree issue before I used it as a superclass). Its subclasses are showing either the old value, or "Молоко (кроме сырого). Продукты молочные и молочные составные, кроме масла из коровьего молока, пасты масляной, сыра, сырных продуктов и мол�", and the beginning of the latter results in that truncated string on autocompletion, making it impossible to save.
