Sylvain Wallez commented on COCOON-2126:
----------------------------------------

A bit of warning: widgets are not block-level components, and are allowed in places where HTML would forbid a div. For example, it is perfectly legal to include a <fd:label> in a <b> tag where a <div> is not allowed. So replacing the <span> with a <div> can actually do more harm than good as a general solution.

So we must have a special behavior for replacements in a <tr> that inserts a <td> rather than a <span>.

Handling this server-side in jx-macros.xml (or JXMacrosHelper) seems quite complicated since we can't grab what is sent to the cocoonConsumer by the JXTemplateGenerator.

The easiest way is most probably to handle this special case in BUHandler.js, in the handlers.replace function: if oldElement is a <td> and firstChild is an empty <span>, then replace firstChild with an empty <td> *with the proper id attribute* (so that it can be replaced again later).

> In a <table> the cells' entries are delivered by a repeater. When hiding a cell programmatically via WidgetState.INVISIBLE the bu:update contains a <span> instead of a <tr> or another hint to hide away the cell. This results in weird optics 'cause <span> is not allowed as child of a <tr>.
> My current workaround: Using <div>s with table* styles.
