Generate lab protocol for FFPE

[Nicklas Nordborg]

This is the second wizard that follows #371. In this wizard the user should select which paraffin blocks that should be processed. The default list should include only those paraffin blocks that hasn't been processed yet (eg. there are no child HEGlass items). It should also be possible to select paraffin blocks manually.

This should be the first wizard. The first step includes selecting a number of Histology items that have not yet been embedded in paraffin blocks. This can be determined by filtering on items without a creation date. To begin with the items should be sorted by bioplate and position, but this will change when the backlog has been processed since then only temporary boxes are used.

The wizards should generate a printable form containing 3 paraffin blocks on each page.

This should now be working. There are two entry points. Just after the 'Move histology' wizard has been completed it is possible to create a protocol for the new PB plates created.

It is also possible to select a specific set of PB plates in a separate wizard. The default list in this wizard currently contain all PB plates but it should only contain PB plates for which no HE glass exists. This remains to be implemented.
