<h2><a name="qualifiedIDs">Usage of IDs with dots (".") in Extension Points, Extensions, and Content Types</a></h2> |
| 38 |
<p> In the past, IDs specified for the extension points, extensions, and content types were expected |
| 39 |
to be "simple IDs" with no dots in them (e.g., "myPoint", not "my.Point", |
| 40 |
not "myPlugin.myPoint"). This rule was specified, but not enforced.</p> |
| 41 |
<p> In the release 3.2 we added processing of fully-qualified IDs (e.g., "org.eclipse.myPlugin.myPoint"). |
| 42 |
However, it turned out that some components had previously used IDs with dots and the change broke |
| 43 |
functionality provided by those components. To preserve backward compatibility for IDs of extension points |
| 44 |
and extensions, we added special processing based on the version of the XML file:</p> |
| 45 |
<p><ul> |
| 46 |
<li>If the XML file has the tag <?eclipse version="3.0"?>, the runtime |
| 47 |
functionality remains the same as before (plug-in ID is added to the simple name)</li> |
| 48 |
<li>If the XML file has the tag <?eclipse version="3.2"?>, the IDs with dots are treated as fully qualified |
| 49 |
names (no plug-in ID is added to the name).</li> |
| 50 |
</ul></p> |
| 51 |
<p> Details can be found in the bug <a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=128866">128866</a>.</p> |
| 52 |
<p> We recommend switching to the 3.2 format as the usage of IDs with dots was never intended to be supported in |
| 53 |
the 3.0 format. (Simply put, there is no guarantee that it works in all cases today or that it will work the same |
| 54 |
tomorrow.)</p> |
| 55 |
<p> This processing of the <?eclipse version> tag applies to IDs of extension points and extensions, but not to |
| 56 |
the IDs of content types (see bug <a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=139491">139491</a>).</p> |
