This really sucks.
We've heard that criticism of combobox before. And having had to use it several times, with and without dynamic data, I agree that it can be a pain. But there's usually a workaround for what you want to achieve. In the code below I set up delegates so that selectItemAt( 0 ) only gets called once the combobox is fully populated.
By "the code below", I mean the code I've attached to this message. Hope this helps!
One way, selectItemAt(0) works properly but the text doesn't show, the otherthe text shows but selectItemAt(0) doesn't work. -----Original Message----- From: Jeff Freedman [mailto:[EMAIL PROTECTED] Sent: Friday, December 23, 2005 9:42 AM To: 'William Krick'; [email protected] Cc: [email protected] Subject: RE: [Laszlo-user] Bug? -- comboboxe dropdown list with invisible items?I think that's because the ReplicationManager hasn't finished populating the floating list yet so there's nothing to select AND the comboBox ondata eventdoesn't seem to fire. I've gotten around that by the following: <textlistitem datapath="listData:/results" text="$path{'@name'}" value="$path{'@id'}"> <method event="ondata"> if (this.clonenumber == 0) { parent.selectItemAt(0); } </method> </textlistitem>Perhaps one of the dev guys can fix the combobox to fire an ondata eventwhen it's populated.

William, Try using textlistitem instead of listitem.

The items are in the dropdown list but the text isn't visible for some reason. When you select one of the invisible items in the list, the combobox is filled with thatitem (the correct behaviour). Why are the items in the list invisible? Is this a bug or am I doing something wrong? <?xml version="1.0" encoding="UTF-8" ?> <canvas> <dataset name="ds" request="true" src="http://eio-online.com/symbols/getyear"/> <combobox editable="false"><listitem datapath="ds:/resultset/result" text="$path{'@modelyear'}"/></combobox> </canvas> _______________________________________________ Laszlo-user mailing list [email protected] http://www.openlaszlo.org/mailman/listinfo/laszlo-user _______________________________________________ Laszlo-user mailing list [email protected] http://www.openlaszlo.org/mailman/listinfo/laszlo-user
