Re: DynamicModel within ListView That Refreshes on ModalWindow Close

You'll have to show us some code (quickstart?), without it it is difficult to 
understand your problem.

Have fun

Thank you Ernesto. I will look into this. 

I didn't mean to be rude, I was thankful for the answer. I was just hopeful
for a followup as the first response didn't address my specific situation,
so I was trying to be direct.

Hi,

It is difficult to understand what you are describing. What I guess is you
have a panel containing a listview and a label and open some modal to do
some operation on listview and after that operation you want the label to
show correct number of elements? If so, make the label receive a dynamic
model not caching the number of elements (e.g. AbstractReadOnlyModel or
LDM). Then I would update the whole panel via AJAX.

Side note: no one in this list is getting paid for answering and helping
people. Maybe starting you messages with "Thanks for your answer... But
unfortunately what you have answered does not help me because ..." might
increase the chances you get answered in the future.

Re: DynamicModel within ListView That Refreshes on ModalWindow Close

2019-09-25 Thread dylanbozeman 
This actually didn't answer my question because what I want to display in the
label is not contained within the ModelObject of my ListView items.

It's a local list defined within the ListView itself.

I want the Label to show a string the represents theList.size() 

but that list size can change as the user opens a ModalWindow that's
available for each item in the ListView.

Just using a regular model doesn't work because then it's not dynamic.

When I try to use a PropertyModel, that doesn't work because it doesn't let
me specify theList.size() as a string.

Hi,

of course you can use a PropertyModel within a Listview, e.g.:

https://github.com/apache/wicket/blob/0a1c33574d08ad9afd2e36a24085d48cdf9efc3f/wicket-examples/src/main/java/org/apache/wicket/examples/forminput/FormInput.java#L213

Or use a CompoundPropertyModel:

https://github.com/apache/wicket/blob/0a1c33574d08ad9afd2e36a24085d48cdf9efc3f/wicket-examples/src/main/java/org/apache/wicket/examples/guestbook/GuestBook.java#L58

Or just use a plain model:

  item.add(new Label("label", () -> 
item.getModelObject().getVariable())); // Wicket 8


Have fun
Sven

Th problem is, the Label isn't refreshing.

I don't believe I can use a PropertyModel within a ListView and I believe I
need that for the Label to by dynamic. (if I can use a PropertyModel, how
so? because I can't specify - new PropertyModel(this,
"localVariableInsideListView") - because it looks at the class level for
that variable)

Is there a way around this or something I am not seeing?

When I do this with a regular Model I am getting:

[qtp976782276-127] WARN org.apache.wicket.page.PartialPageUpdate - Component
'[Component id = numberLabel]' not rendered because it was already removed
from page
