Attribute values sometimes do not show up in the selection list, but clicking to another tab and then back causes them to appear

David Retzler (8811) | asked Jan 18 '13, 3:05 p.m.
We have a custom work item type in RTC  Sometimes when we open an existing work item the drop-down fields only show the attribute values already assigned to each of them and opening the drop-down list for each field seems to indicate there is only that one value available, even though there should be several more listed.  Moving around the work item usually seems to resolve it, for example clicking to another tab on the same work item and then clicking back to the original tab and opening the drop-downs now displays the values to select from.  It is difficult to reproduce, or figure out some sort of pattern as to why.  So far we have not been able to find a logged defect or forum item describing this.  Any ideas?

Are the drop-downs custom attributes on the custom work items? If so, how are the values provided? Is this in the web ui or the Eclipse ui (or both)?

The attribute value is loaded immediately and the list of available values is loaded asynchronously. Depending on the performance of your system, this may explain why clicking around (i.e., allowing time to pass) resolves the issue -- and why sometimes it all happens fast enough that you don't see it. There may also be a refresh issue (which may be unique the the client in use). If you'll respond to my comments above we can look a little deeper.

Thanks Millard, this is using the web ui.  It does not seem to be simply a system performance or loading issue, as in some cases it is an issue for several hours.  We thought about the browser refresh possibility as well, but it does not seem to be that - refreshing the browser did not seem to have an effect.  However, it does seem to be machine-dependent, as in one particular case I was able (by moving around the work item, saving, etc. as described) was able to get the drop-down values to appear while at the same time another user on his machine did not see them!  After having that user first try to refresh his browser, without success, then having him do some "moving around in the work item" on his own, the values appeared.

Furthermore, it may actually be browser dependent as well, as it evidently seems to occur in Firefox, but not in IE.  For FF, we are using ESR 10.0.x

What about the attributes and values? Do you see this behavior for built-in attributes (e.g., does this happen with Type or Priority)? Any process customizations?

If you use the Eclipse UI do you ever see the issue there? Is it always reproducible or more of a "darn, it's happening today" thing? Next time you see it, rather than refresh at the browser level, can you try the work item refresh in the work item toolbar instead? I realize FF10 is supported as of but do you recall seeing this with FF 3.6?
