Permission column causes NPE in biowells list

[Nicklas Nordborg]

Create a bioplate and enter the view page.

Switch to the "Wells" tab.

Add the "Permissions" column.

This causes a NPE:

java.lang.NullPointerException
...at net.sf.basedb.clients.web.taglib.table.ColumnDef.doStartTag(ColumnDef.java:750)
...at org.apache.jsp.biomaterials.bioplates.wells.list_005fbiowells_jsp._jspx_meth_tbl_005fcolumndef_005f15(list_005fbiowells_jsp.java:3436)

To get rid of the problem go to BASE -> Reset list settings and select the Biowell option in the Which list? list.

Biowells have no permissions on their own so the "Permission" column should not be in this list.

The "Permission" column has been there a long time but has not caused any problem until BASE 3.10 (​http://base.thep.lu.se/changeset/7215). This changed the "Permission" list from being a static hard-coded list to a dynamic list, only showing logical alternatives. The code in ColumnDef should be updated to handle the null or empty list case.
