Prevent empty traits from being included in the Code view and/or toHTML result

[protozoo]

Hi there,

I have a few components with a text-type trait set to null by default.

If the user doesn't change it, this trait is not included in the HTML output as an attribute (that's fine!).
HTML Output: <mycomp />

If the user edits the trait, setting its value to X, this value is included in the output HTML too (fine again!).
HTML Output: <mycomp mytrait="X" />

However, if the user deletes the content of the trait field leaving it empty, the HTML output still includes the attribute with an empty string:
HTML Output: <mycomp mytrait="" />

Is there any way from preventing the attribute from being. included at all?
Expected HTML Output: <mycomp />

Many thanks!

Attributes with null, undefined, false values are not returned in HTML output, but the empty string is valid, so you should probably set a listener and reset those values in the case are empty.
