Hi,
we faced a problem, we have created Vaadin (6.2.5 version) portlet which can work on Liferay 5.2.3, but when we try to deploy the same portlet (changed configuration files) under Liferay 5.0.1 error happens: (below is the error message from Firefox vaadin debug window)
Vaadin application servlet version: 6.2.5
Widget set is built on version: 6.2.5
Application version: NONVERSIONED
inserting load indicator
Making UIDL Request with params: init

We looked into /html/VAADIN/widgetsets/com.vaadin.portal.gwt.PortalDefaultWidgetSet/7A77340041A9878AF8784E8BBFFABE09.cache.html file, and there is no ) missing.
When using Safari to debug, it showed another error, which is
Communication error: (SyntaxError): Parse error line: 1 sourceId: 4752244600 - Original JSON-text:…
We have modified ROOT/WEB-INF/classes/portal-ext.properties
added VAADIN folder under ROOT/html
added vaadin.jar (removed version text), under ROOT/WEB-INF/lib
changed portlet.xml, liferay-portlet.xml, liferay-plugin-package.properteis, liferay-display.xml
We tried to create Hello World portlet to test, and got the same error when use Liferay 5.0.1
Thank you
