Ronald van Kuijk commented on JBPM-2712:
----------------------------------------

Last comment by Martin should be ignored, this was due to a usererror.

'custom' element should be changed to:

			<element name="custom">
				<annotation>
					<documentation>Uses a user defined, custom implementation of
						ActivityBehaviour
        </documentation>
				</annotation>
				<complexType>
					<complexContent>
						<extension base="tns:wireObjectType">
							<sequence>
								<element ref="tns:on" minOccurs="0" maxOccurs="unbounded" />
								<element name="transition" minOccurs="0" maxOccurs="unbounded">
									<complexType>
										<complexContent>
											<extension base="tns:transitionType">
												<sequence>
													<element ref="tns:timer" minOccurs="0" />
												</sequence>
											</extension>
										</complexContent>
									</complexType>
								</element>
							</sequence>
							<attributeGroup ref="tns:activityAttributes" />
						</extension>
					</complexContent>
				</complexType>
			</element>

> It should be possible to add a <timer> as the child of the <transition> element contained within a <custom> activity in the same manner that it is for <state> activities. If a custom activity executes a waitForSignal() inside the execute() element (as is the case in our use case) then we need to be able to put a timeout on this activity such that if no signal is recieved within a specified period the timeout will fire and action can be taken. This is possible in a <state> activity but currently not in the custom activity. We tried to do this by changing our <custom> with a <state> and this worked for the timeout but the signalling then failed (see JIRA JBPM-2711) so currenty we can find no solution to this issue.
