Use of macro in opi_file property of a linking container widget

[utzeln]

It is possible to use a macro for the OPI file in action "Open OPI --> File Path = ${OPI_FILE}.opi".

But trying to use a macro in the linking container widget fails:

2016-03-11 14:12:48.987 WARNING [Thread 1] org.csstudio.opibuilder.persistence.XMLUtil (fillLinkingContainerSub) - Failed to load LinkingContainer opi_file /m-TEST/src/main/boy/${OPI_FILE}.opi
java.lang.Exception: Cannot open /${OPI_FILE}.opi (No such file or directory)
at org.csstudio.opibuilder.util.ResourceUtilSSHelperImpl.pathToInputStream(ResourceUtilSSHelperImpl.java:127)

ITER use case is that the navigation pane shall be able to load only the mimic part of the display which is in a linking container.
