'Populate List from Array' on page load

Is it possible to 'Populate List from Array' on a page load event (together with onChange of parent list1)?

I have a list of buttons on one page which submit IDs of list1 and IDs of list2 as GET parameters. On the form page the list2 values are populated by onChange event of its parent list1.

Now I want the list2 values also shown and selected by its submitted ID, when the page loads. Otherwise the user has to select the values again (which he already has by selecting the button of the first pasge).

Thanks for any help.

yes, you can add the Populate list from array behavior to the body unload event.

first you will need to create the URL Variable bindings. on the bindings panel, click the plus button, select URL Variable and name the bindings.

The in the Dreamweaver tag selector, select the Body tag and then add the Populate list from array behavior. you will also want to use the Set Selected in list behavior to use the URL Variable bindings to set the list selected value.

Thank you so much Jason. Perfect support!

You're welcome.

Is "Set Selected in list " only working with URL variables? I tried to do this with Session variables, but it's not working...

It should work with sessions as well, you may need to add a session start command line of the page to force it to see the session:

<?php @session_start(); ?>

when in doubt, add the session binding to the body of the page to double check that it is returning a value.

The Session returns the correct value. Here is the onLoad statement:

WA_setSelectionsInChildList(MM_findObj('Sitzungszimmer'),<?php echo $_SESSION['Sitzungszimmer']; ?>);WA_FilterAndPopulateSubList(rsBestuhlung_WAJA,MM_findObj('Sitzungszimmer'),MM_findObj('Bestuhlung'),0,0,false,': ');WA_FilterAndPopulateSubList(rsDauer_WAJA,MM_findObj('Sitzungszimmer'),MM_findObj('Dauer'),0,0,false,': ');WA_setSelectionsInChildList(MM_findObj('Dauer'),<?php echo $_GET['Dauer']; ?>);WA_setSelectionsInChildList(MM_findObj('Bestuhlung'),<?php echo $_GET['Bestuhlung']; ?>);WA_FilterAndPopulateSubList(rsVeranstaltungVon_WAJA,MM_findObj('Dauer'),MM_findObj('EventVon'),0,0,false,': ');WA_FilterAndPopulateSubList(rsVeranstaltungBis_WAJA,MM_findObj('Dauer'),MM_findObj('EventBis'),0,0,false,': ')

If I use <?php echo $_GET['Sitzungszimmer']; ?> instead of <?php echo $_SESSION['Sitzungszimmer']; ?> it works. This is the "master-value"
that makes all other lists poulate.

Another problem is, if one of the other GET parameter is emtpy or missing, none of the lists is being populated.

if you add:

||<?php echo $_GET['Sitzungszimmer']; ?>||<?php echo $_SESSION['Sitzungszimmer']; ?>||

to the body of the page, what does that return?

If one of the get variables is missing is wouldn't expect it to work, there is no way for it to know what is selectedf in the parent list, etc...

you could force a default value using isset if you like, for example:

<?php echo((isset($_GET['Sitzungszimmer'])?$_GET['Sitzungszimmer']:1); ?>

this will use the value of the GET Variable if it exists or 1 if not.

I made a stupid type error, arghh ... $_SESSION['sessSitzungszimmer'] is correct not $_SESSION['Sitzungszimmer']

Sorry for that, and thanks for your efforts.

I'll try the default value idea. Thanks Jason!
