Mike Hello. Im 99% sure the framework its ok. This is what I have, WOComponent 1 Main AjaxSelectionList a.k.a SL1.
WOComponent 2(parentComponent) has 2 children, WOComponent 2.1 (child1) and WOComponent 2.2(child2) I did this because in another page Im reusing child1 only, so I didn't put all in a single WOComponent. So, child1 has an AjaxSelectionList a.k.a SL2, which is wrapped in a AjaxupdateContainer a.k.a AUC0 this container gets updated when selecting an item in a MAIN SL1, also inside the AjaxSelectionList there is another AjaxUpdateContainer, a.k.a AUC1. child2, has a AjaxUpdateContainer which get's updated when selecting something from SL2. Putting only the things in question, child2 has 3 AjaxSubmitButtons, add, update, delete, and a TextField, when pressing any of those AjaxSubmitButtons, I go to the corresponding WOActionResult method, ask the parent, (parentComponent) for the selected element of SL2, then create a new EO' and add to the relationship of the selection, update it, or deleted. and the updateContainerID binding of each of the buttons its bound to the id of AUC1. So because of the structure Im using, to be able to communicate child1 and child2 I have to do it through the parentComponent. (dunno if this is relevant or no, maybe.... ?) Im not using the back button at all, Im not opening new windows, Before, like 3 days ago, Amadeo made me realize I had a problem with some id's inside SL2, so I created a method that returned a unique Id for that item in the list, and bound the result to the id binding. but even before this change the problem was there, but I dunno if it's me or what but it happens more often, I think. mm what you think? :-( . g.
