The dot is removed by the browser and results in a value of 25 if you choose 0.25 (hence the error below).
The example config with listitems results in a dropdown in TFS. This works fine in Firefox. Chrome and Internet Explorer remove the dot and e.g. transform the value 0.5 to 5
<FIELD name="Effort" refname="Microsoft.VSTS.Scheduling.Effort" type="Double" reportable="measure" formula="sum">
<HELPTEXT>The estimated effort to implemented the backlog item</HELPTEXT>
<ALLOWEDVALUES expanditems="true">
<LISTITEM value="0" />
<LISTITEM value="0.25" />
<LISTITEM value="0.5" />
<LISTITEM value="1" />
<LISTITEM value="2" />
<LISTITEM value="3" />
<LISTITEM value="5" />
</ALLOWEDVALUES>
</FIELD>
It can be solved for Internet Explorer by putting English as language preference, but that is not a solution since most of our users have set Dutch. Setting the dot as a decimal separator isn't a solution either, because Dutch uses a comma for that.
How can I solve this without bothering the end user?
