Michael Brohl commented on OFBIZ-12678:
---------------------------------------

Hi [~FloMo] , as this is an improvement, the affected version and fixed versions should be trunk/upcoming branch.

Regarding the change, are there any expectations for the runtime performance when FlexibleStringExpander is used on many occurrences?

> For now, "disabled" and "read-only" attribute types on form elements (text, check, textarea...) is "boolean".
> It would be nice to be able to define their values with an evaluated expression :
> {code:java}
> <text disabled="${someVariable > 4 || someOtherVariable}" />{code}
> This means switching to a string type for these attributes, and use a FlexibleStringExpander in the rendering process.
> There may be more attributes that would benefit from this.
