Olivier Heintz commented on OFBIZ-5073:
---------------------------------------

After reading commit Trunk @Rev1392766 about OFBIZ-2628, I do not saw a 
relation with portal.
So I have make correction at the screen / form level
before in Form
{code}
        <field name="portalPageId" title="${uiLabelMap.CommonEdit}">
            <hyperlink description="${uiLabelMap.CommonEdit}" 
target="ManagePortalPages">
                <parameter param-name="portalPageId"/>
                <parameter param-name="parentPortalPageId" 
from-field="parameters.parentPortalPageId"/>
            </hyperlink>
        </field>
{code}

and I have as result in the web browser
the error message and in source
{code}
<input name="parentPortalPageId" value=" <html> <head> <title>Open For Business 
Message</title> <meta http-equiv="
{code}

After, I have added in action part of screen
{code}
                <set field="parentPortalPageId" 
from-field="parameters.parentPortalPageId"/>
{code}
and in Form, i have changed
{code}
        <field name="portalPageId" title="${uiLabelMap.CommonEdit}">
            <hyperlink description="${uiLabelMap.CommonEdit}" 
target="ManagePortalPages">
                <parameter param-name="portalPageId"/>
                <parameter param-name="parentPortalPageId"/>
            </hyperlink>
        </field>
{code}

And now, all is fine.

I not understand why the initial solution not works (but I not understand the 
content of @Rev1392766 commit, it's too technic for me ).

Hoping that it helps to find the proper correction.
