What's the point of CommonEmptyHeader?
It's definied in CommonUiLabels.xml as:
<property key="CommonEmptyHeader">
<!-- do not remove this! -->
<value xml:lang="en" xml:space="preserve"> </value>
</property>
It is just a simple space (0x20)
It is used ~500 times in forms as a title in a field definition
Example:
<form name="EditPerson" type="single" target="updatePerson"
...
<field name="cancelLink" title="${uiLabelMap.CommonEmptyHeader}"
<hyperlink target="${donePage}" also-hidden="false"
description="${uiLabelMap.CommonCancelDone}">
<parameter param-name="partyId"/>
</hyperlink>
</field>
</form>
This is a button which should have no label, but if the title attribute
is empty then the name attribute is used as label.
Why not just put a space (" ") into the title attribute - still a hack,
but exactly same result a using CommonEmptyHeader without the need using
CommonEmptyHeader.
The real solution is of course not to display a label if the title
attribute is empty.
An empty title attribute is meant to be a shortcut, or a developer's
convenience - the widgets will use the field name to look up the correct
label.
Ah, ok that's this FormFieldTitle_ stuff (which I don't like and use ;-)
- IMHO it is bad for re-using labels...)
Putting a space in the title attribute is the only way to turn off the
default behavior.
Ok, so there is nothing against replacing
"${uiLabelMap.CommonEmptyHeader}" with " "?
That is what we would like to do - but it doesn't work. That is what
needs to be fixed.
