EXECUTE: Create Struts 1.2 Kickstart project. Target runtime and server - AS 4.2.3GA.
EXECUTE: After server startup. Right click on project in Package Explorer. JBoss Tools > Remove Struts capabilities. Enable "Dynamic Web project" chackbox.
EXECUTE: Right click on project in Package Explorer. JBoss Tools > Add Struts capabilities.
EXECUTE: In last step select AS 4.2.3GA runtime and enable checkbox with target server.
EXECUTE: Run server from server view.
FAILURE: Exceptions appears in Console log during project deployment. Project cannot be started on server.

Problem is in "target server" checkbox at last step of "Add Struts capabilities" wizard. Seems that project deployed to server before finishing all "Add Struts capabilities" tasks.

In Add JSF capabilities wizard in same situation project deployed correctly.
