Default value for select when selecting an empty value option

I have the following html:

<select name="attr_initiative_ability">
  <option value="">—</option>
  <option value="strength" data-i18n="STR">Str</option>
  <option value="dexterity" data-i18n="DEX" selected>Dex</option>
  <option value="constitution" data-i18n="CON">Con</option>
  <option value="intelligence" data-i18n="INT">Int</option>
  <option value="wisdom" data-i18n="WIS">Wis</option>
  <option value="charisma" data-i18n="CHA">Cha</option>
</select>

If I select the first item I get the following in the console:

FILLED IN A DEFAULT VALUE FOR initiative_ability

And then dexterity is re-selected. Though this only happens once.

I assume there is a check for a value and if no value is found then it sets it to the selected value. However it should be checking for undefined instead.

Thanks!

When I make sheets, for select boxes, I usually make the first section have a value equal to zero, so any associated button works but doesn't add anything. 

<select name="attr_initiative_ability">
  <option value="0">—</option>
  ...
  ...

</select>

I understand that I can make it 0, but I don't want the value to be 0. I want it to be empty.

This is something we have looked at and discussed many times amongst the dev team. The problem is that the way FireBase works is that a blank value is turned into "no value", to save space, and we assume that "no value" means "use the default value". This is why, also, when a sheetworker sets a value to "" the sheet doesn't actually show the change because the value is deleted rather than "changed" and the sheet can't track changes on a value that doesn't exist any more.

If we changed this behavior it would be difficult for us to be able to tell if "no value" is because it's a new character and we need the use the default value, or if it's "no value" because the value has been set to "" so we show "blank".

Ah, Understandable Phil. Sorry If I worded the above a bit aggressively.
That's rather unfortunate. I'll have to think of a different way to set a default then - likely via sheetworkers on page creation. This can be closed then - I'll find a different solution.

When you get a chance can you take a peak at An Attribute set to 0 no longer shows on the sheet. A player recently had this come up for them and I don't think I can do any kind of work around to make it work.

Yeah, sorry it's an inconvenience and sorry I don't have a better answer than "we tried". It's something we've approached several times and have not found a alternative that isn't worse than the current situation.

P.S. I responded to the other thread.
