Value 0 of nested array not displayed and module can not be saved.

[fallhunter]

When use [{type:Number}]

the value 0 will not be displayed in the input widget, I found
res.write('\n<input' + (this.value ? ' value="' + escapeHTMLComponent(this.value) + '"' : '') );
at line 60, widgets.js. where this.value will treat 0 as no value and display nothing.

And,
when you try to save an array [{type:Number}], for the 0 was not fill in the input field,
the form will post nothing to the server, and make exception in the server like:

Cast to number failed for value "NaN,NaN,NaN,NaN,NaN" at path "xxxx"

[alonronin]

you should use [Number] or [{type:Number}]
it is case sensitive.

Yes, in my code it's "type", just typo in the issue. please look into this.

There were three issues here, two where solved.

• Not considering 0 as a valid value, hence not rendering it
• Not showing correct error message for failing to cast empty value into a number
• Erroneously turing null in NaN, thus failing the cast.
