Saved views: "Input string was not in a correct format" when filtering on Int32

[jelling]

I have setup my page to load and save views. This works fine for the most part but when I reload a view where I've filtered on an integer column I get the error below. Note: the filter works  when you create it, it's just when it's reloaded from the db. Other saved views such as text matches work also after reloading so it appears to just be integer comparisons.

Is there an internal build that fixes this issue? I am scheduled to release on Wednesday and we just discovered this.

Hello Jon,

Can you please verify that the column you are formatting is of the proper DataType? This should ensure that the filtered values will be formatted properly. You can review the Description section of this online example along with the help article linked in it for more details:
