Hi, every time I update Jeveasset with a new release the average purchase columns resets.

How can I maintain such information between updates?

In my case it seems to be an error getting price data for item types 33578 and 33579 from EVE Central. EVE Central is returning a 400 error with "A non-marketable type was given" when jEveAssets tries to fetch prices for those item IDs. I will try some of the other price sources when I get a chance...

@Annette Nolen
Thank you for your great bug report. It's exactly the information I needed! :)

I consider this a Eve-Central bug, not a jEveAssets bug.
All the other price data providers have the item included...
I'm not too keen on making a workaround for eve-central.
I will need to hard code it, if the items still has to work on with the other Price data sources...
Meaning I'll have to release another version when eve-central eventually fixes it.

I'm much more inclined to just have people use another price data source...

This is of course open for discussion - I can change my mind if the argument is good enough ;)

Thank you for the extra info.

How did EWA handle it?

Not at all, so far. I'm counting on the EC guys to fix it, after all EM does handle it. I feel like creating an "out-of-SDD-exception-list" because a 3rd party site currently throws an error in a very specific situation is a) not the right way to handle it and b) too much effort.

A very lazy approach for me/EWA could be to set the published flag in invTypes to 'false', for the time being. That would be a SQL one-liner, which could be executed in EWA's integrated DB manager. But that would hide/disable the shirt(s) from everything in EWA.

I will release a bug fix release soon(tm)

I ended up doing extensive testing of the pricing library, as I wanted jEveAssets to still be able to use eve-central when some of the typeIDs return errors. The problem is that jEveAssets get prices in batch of 100. The entire batch will fail even though only one typeID is missing @ EC. So we need to find the error typeID(s)

My first solution was to get each ID of the failed batch one at the time: 100 requests (best/worst)
My second solution was binary search: best 14 worst 204
My current solution is exponential search: best 14 worst 110

Best = Only one typeID in the failed batch return errors
Worst = All typeIDs in the failed batch return errors

@Lord Jita
I do (because I wrote the code :D), and you're not going to be happy:
Contract > Excluded = Buy contracts
Contract > Included = Sell contracts.

And now to the epic fail part: It doesn't matter who the owner is, so:
Included; Contracts selling items to you or your sell contracts
Excluded: Contracts buying items from you or your buy contracts

I know it's really confusing ATM. - It will get better in the next release, promise.
Until It's fixed, you can disable contracts in the Assets Tool:
Options > Options... > Assets > Include Contracts
And use the Contracts Tool to get the full picture.

Hi, I'm getting an error when updating assets.

I'm guessing it's because jEveAssets hasn't been updated for Rubicon 1.1 yet?

Hi, I usually use Jeve to track the average purchase of my items.

Today it was reset.

The only new things I've done is to set the API key for a new toon (the trader).

Is it normal? Is it a bug? Thank you

In the asset tab there is a column that show the avg purchase.

I thought it means the everage price I spent to buy that item. Is it thrue?

That column now only contains the prices for the items I bought today.

Ok, my english is orrible but that was my idea.

Anyway yesterday all prices and the market orders reset.

Is it because I added another API key or something else?

Thank you
