> Icons are created if the string for the resource is an empty string in
> Trinidad 1.2

> Key: TRINIDAD-2039
> URL: https://issues.apache.org/jira/browse/TRINIDAD-2039
> Project: MyFaces Trinidad
> Issue Type: Bug
> Components: Components
> Affects Versions: 1.2.15-core
> Reporter: Andrew Robinson
> Assignee: Andrew Robinson
> Priority: Minor
> Fix For: 1.2.15-core
>
>
> The toResourceUri in CoreRenderer returns null for a "" value in Trinidad 2
> but not in Trinidad 1.2. What happens is that icons that may evaluate to
> blank strings (like EL bound icon attributes) may end up rendering a <img
> src=""> tag in Trinidad 1.2. This results in an extra call to the server in
> at least some browsers.
> We should backport the fix from Trinidad 2 to 1.2 to prevent this from
> happening.
> Issue can be reproduced easily with this code:
> <tr:commandButton id="search" text="Search" icon="" action="search"/>
