I’m encountering a non-tool specific bug with drop down lists.
Tool collection selector loads only the 50 most recent eligible datasets. Running a job increases the count from 107 to 108, displays the new output, and removes the previous 50th item, while remaining stuck at “Loading 50 of 108.”
Reproduced on multiple computers

Is there a known fix for this?
Thanks,

Welcome @12Benne
Would you be able to explain this more? Maybe with some screenshots?
It sounds like you are talking about the pull-down menu on tool forms, the input selector, but if it is that I am not sure how running a job could change it, hence my confustion.
I can add that filtering the history panel view is one way to “pre filter” what is displayed in the history panel, however I am not sure if that is what you may be talking about either.
I’ll watch for your comments! 
I recently experienced this issue, too. It seems to happen with large enough histories when Galaxy populates the input selector drop-down list with the first few items, then tries to load more and kind of gets stalled there. Don’t know if this is Galaxy Europe-specific or if you can reproduce this on the U.S. server.
@12Benne as a workaround for you, in case you haven’t discovered this yourself, you can always just drag and drop the dataset you want to use into that field of the tool interface.
We need to fix the underlying issue though.
@jennaj it doesn’t have to do with running tools directly, just that you can always only access the latest 50 eligible inputs in that drop-down list so running a tool adds a new possible input on top, but drops one from the bottom of the list.
Thanks for the tip, I was about to resort to shuffling things between histories. It seems to be back functioning now but I will keep that in mind if it happens again.
