ShortDesc for af:column

Question

I have a table with filterable columns and want to add a popup hint to the filter input to help users with search conditions, similar to how a hint on the date format is automatically added when filtering by date on a column. I thought the shortDesc attribute for af:column does that, but it does nothing.
Anyone know if that's the right attribute? or how to implement a popup tip like the date column filter?

Answer 1

Ok I tried the things mentioned in the link you posted, but they don't work either. I created a Resource Bundle-Based Help, and used the HelpTopicId attribute to display a note window popup, but it doesn't show up that way either.
The document says that ShortDesc should work too but it doesn't, so my question is why doesn't it?
Here is how I coded my af:column tag:
<af:column sortProperty="#{bindings.ChNoteView2.hints.Note.name}"
filterable="true" sortable="true"
headerText="Clinical Notes" id="c1" width="250"
filterFeatures="caseInsensitive"
helpTopicId="ICHT_FILTER_COLUMN_TEXT" shortDesc="Some Help text here.">
<af:outputText value="#{row.bindings.Note.inputValue}" id="it5">
</af:outputText>
</af:column>
I am expecting to see a note window popup displaying "Some Help text here." but nothing happens when I click into the column filter input.
