| 23 : | If you are using the action-based extension points, then you may want to specify | ||
| 24 : | either a <code>definitionId</code> or a non-empty <code>label</code>. If you | ||
| 25 : | don't do this, then in the "Uncategorized" category, there may be commands | ||
| 26 : | called "Legacy Action With No Label". They will appear in the keys preference | ||
| 27 : | page. A warning will be printed to the log. | ||
| 28 : | </p> | ||
| 29 : | <p> | ||
| 30 : | In 3.2, all actions are converted into commands when parsing the registry. As | ||
| 31 : | such, actions without a definition id have a command generated for them. This | ||
| 32 : | command needs a label, which is typically drawn from the label on the action. | ||
| 33 : | In the case of actions appearing in the tool bar, sometimes neither a definition | ||
| 34 : | id nor a label were specified. | ||
| 35 : | </p> | ||
| 36 : | dj | 1.5 | |
| 37 : | <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 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 : | curtispd | 1.6 | <ul> |
| 46 : | dj | 1.5 | <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 : | curtispd | 1.6 | </ul> |
| 51 : | dj | 1.5 | <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> | ||
