Hi Geert,
Thanks for the great answer. :)
I have an additional question to the second option(input, output,
datalink).
My embedded element 'MAINMENU' includes a link that set the output
'mainMenuSelection':
template.setValue("subsite_url", getExitQueryUrl("import",
new String[]{"mainMenuSelection", "import"}));
The element 'MAINMENU' has the following definition:
<element id="MAINMENU" file="elements/termmanagement/mainMenu.xml"
inherits=".IDENTIFIED">
<flowlink srcexit="import" destid="IMPORT"/>
<datalink srcoutput="mainMenuSelection" destid="IMPORT"
destinput="mainMenuSelection"/>
</element>
Content of mainMenu.xml:
<element
implementation="com.acrolinx.portal.termmanagement.elements.MainMenu">
<input name="mainMenuSelection"/>
<output name="mainMenuSelection"/>
<exit name="import"/>
</element>
The element 'IMPORT' gets the value 'import' of the input
'mainMenuSelection'.
The element 'MAINMENU' is embedded in the template of the 'IMPORT'
element.
So the 'MAINMENU' element is processed again and it has an input
'mainMenuSelection'.
But the value of the input 'mainMenuSelection' is null for the element
'MAINMENU'.
What must I change, or did I missunderstand you a little bit?
Cheers,
Lars
