Bug 150776 Binding parameters of datasources are not evaluated when datasource in a library
I used to defined a datasource with binding parameters (depending on parameters ...). It works well when datasource is defined in the report, but when i tried to put this datasource in a library, binding expressions are not evaluated or not used by the datasource. When debugging the code, two datasources appears, the initial from the library (module=Library) and the linked from the report (module=ReportDesign). The dataset used the datasource of the report, but no binding values are found on the report datasource. The datasource from the library is evaluated correctly but not used.

	/**
	 * Returns the display label for this element. The display label is the
	 * localized display name to be shown in the UI. The display label is one of
	 * the following:
	 * <p>
	 * <ul>
	 * <li>The localized display name of this element, if the display name
	 * resource key is set and the localized string is available</li>
	 * <li>The static display name property text of this element, if set</li>
	 * <li>The name of element, if set</li>
	 * <li>The localized display name of this kind of element, which is defined
	 * in metadata, if set</li>
	 * <li>The name of this kind of element, which is also defined in metadata
	 * </li>
	 * </ul>
	 * <p>
	 * The user can also decide at which detail level the display label should
	 * be returned. The level can be one of the following options:
	 * <p>
	 * <ul>
	 * <li>USER_LABEL: Only the first 3 steps are used, if not found, return
	 * null</li>
