Can I use this add-on in vaadin-portlet (on liferay 6.2.1)?

[cccnam5158]

Actually I applied this add-on to my vaadin-liferay-portlet.

Env.

• Liferay 6.2.1 CE GA4
• Vaadin 7.5.2
• dawn theme 11
• digram-builder org.vaadin diagram-builder 1.1 jar

Result

Diagram Builder was successfully displayed. but.. no response when i clicked liferay's portlet's edit button. and i cannot drag and drop component.

here is my chrome's console log.

Uncaught TypeError: Cannot read property 'skin-sam-aui-sortable-layout' of undefined Uncaught TypeError: Cannot read property 'aui-autosize-deprecated' of undefined Uncaught TypeError: Cannot read property 'liferay-dockbar-keyboard-interaction' of undefined
