Adrian Crum commented on OFBIZ-4358:
------------------------------------
Example:
{code}
<field name="removeBtn" widget-style="smallSubmit"
title="${uiLabelMap.CommonEmptyHeader}">
<hyperlink description="${uiLabelMap.CommonRemove}"
target="deleteItem">
<parameter param-name="param1"/>
<parameter param-name="param2"/>
<parameter param-name="param3"/>
</hyperlink>
</field>
{code}
If param2 does not exist in the rendering context, the URL will contain
"param2=null". It should be rendered as "param2=" or the parameter should be
left out of the URL.
> Form Widget Hyperlink Field Renders Non-Existant Parameters As "null"
