| #53 | open | Errors during save may corrupt a database | administrator | jeroens |
| Description |
If a database error occurs during an attempt to save a model or scenario, existing rows may be affected to a degree that they are no longer usable for loading. To prevent users from losing work, EwE must have some type of rollback mechanism. Some research needs to be dedicated whether adodb.net can use proper SQLTransactions for performing rollbacks in case of save errors. If transactions cannot be used, we may have to build a hokey solution that copies the current .MDB file to a safe location (at either regular intervals or right before any changes are to be made) so we have a way to revert to a working DB. |

| #55 | open | Ecopath fishery tabs default values are different than version 5 | administrator | carieh |
| Description |
After I had added in 2 fisheries to the model (Carie test lab 1 may 21), I added in the fleets and then went to the market pricetab. In version 5 the default is for every group (including detritus) to have a value of 1. This is not the case in version 6.0.0.6, The default fishing fleet which I renamed, was set to 1 as defaults (except detritus), but the second group I added had values of 0 for all defaults. I think this is something you might want to double check on. shoud detritus have a default market price of 1? When I added in more fleets into version 5 (even without assigning catch values) the market prices of all fleets were 0- with the exception of the fleet that had catches assigned to it, then the prices were set to 1. In version 5 all fleets have a market price of 1 even if they do not have catches assigned to them- just a discrepency in the default values. Indeed, just defaults in the database. Fixed. |

| #94 | open | Model balancing- biomass in habitat area reading incorrect values | administrator | carieh |
| Description |
Sorry you get the long version..... So in the process of balancing a model. These are models from Villy's class that he has set up to be unbalanced, so the imported version needs to be adjusted before balancing. In this model I have made a few changes to the whale, seal, and phytoplankton groups. I have altered the biomass of seals from 0.01 to 0.02, the P/B for whales form 2 to 0.08, and deleted the phytoplankton biomass. This is where I get the problem. The altering of parameters seems to be fine (whales and seals) as in the EE estimated by the model, but the phytoplankton is where I have the problem. Also the EE for every group comes out correctly (so the model seems to be balancing correctly). Where I have the problem is when I delete the biomass for phytoplankton. When I move to the basic estimates the biomass of phytoplankton is calculated correctly at 12, in the biomass column, however the biomass in habitat area remains at 0.(it should be 12, and all other groups are correct). I am not sure if this is an actual bug, as the values for EE and biomass are being caluclated correctly or if there is a problem in the calculation. Model 2a june 15th. on ftp site related to bug 95 (the issues with the 0 value in the cell as opposed to a blank cell. |
