I have an issue with my library of components: the wbp-meta folder is ignored if my library project is not imported in the Eclipse workspace.
Here is my test case:
* change your target platform to reference the attached bundle com.sneda.wb.issue1_126.96.36.199109051047.jar
* create a new Plug-in Project
* Add com.sneda.wb.issue1 as a plugin dependency
* Add the component com.sneda.wb.issue1.api.MyComponent1 to the palette
Here you should see a purple square icon as the image of MyComponent1 in the palette. You should also have a property "myProperty" with true as default, in the Properties part of the WB editor (defined in MyComponent1.wbp-component.xml).
