Re: ListMultipleChoice Update Model from Choices
Hi
Yep, I got it now. Thanks. I now create a new instance of the Model itself.
This satisfies the comparison.
if (!getModelComparator().compare(this, object)){
...
}
Earlier I was only resetting the contained object within the Model.
Thank You !

Not necessarily. Look at setmodelobject implementation:
public final Component setDefaultModelObject(final Object object)
...
if (!getModelComparator().compare(this, object))
{
modelChanging();
model.setObject(object);
modelChanged();
}

Re: ListMultipleChoice Update Model from Choices
Hi
Yeah I did have only the setModelObject() but it did not clear it that is
why I added this. Maybe I have not used it correctly.Since you mentioned
'Note: componentInstance.setModelObject will call modelChanged from within
if the model is actually changed'
If the model is actually changed. That is what I am not sure, when does it
get notified that a change has happened.?Setting of an entirely new instance
in the model should do that isn't it. Please see code below.
FYI:
StudyModel is the bean that contains other objects. It is bound to a form
using CPM.
onNew(){
StudyModel studyModel;
if(form != null && form.getModelObject() != null){
studyModel = form.getModelObject();
studyModel.setStudy(new Study());//a hibernate entity
form.setModelObject(studyModel);
form.modelChanged();//--> added this one to clear the data.
form.clearInput();
}
Thanks again
Niv

Re: ListMultipleChoice Update Model from Choices
Just wanted to update, I have checked out the Palette too and looks cool. However wanted to share this bit. Adding the following componentInstance.modelChanged(); componentInstance.setModelObject(selectedChoice); ie, I get the choices selected and add it to the Model. By invoking modelChanged() I noticed that the changes are pushed into the Model. Which is what I was looking for The other usage of the modelChanged() I noticed was when 1. On the Form the user types in some information and then hits Save. 2. The form comes back with validation error messages. 3. The user now clicks on Cancel button to discard the form 4. The user clicks the New button and a form is loaded with the old data( I had the data typed in the previous form repeated even though I cleared the input form.clearInput.) 5. I add the form.modelChanged() and now it clears completely or takes into account that its a fresh form. Is this a valid approach? Any thoughts on it for similar scenario?

Hey Mate!!, That is classic. Will check it out, great. Again if you do know how I can address the issue I had will be good to know even if I dont use it since the Pallete offers it. Thanks !!

Re: ListMultipleChoice Update Model from Choices
Hi!

ListMultipleChoice Update Model from Choices
Hi All, I use the ListMultipleChoice(LMC) in a different way. I have one control (LMC) on the left representing a list of items Available (roles for example) I have another LMC to represent Selected items(roles) The ADD and ADD ALL buttons move the "selected items' from Available LMC to Selected LMC. Now when I hit Save, the Selected LMC's Choices are not pushed into the Model and is empty. However, when I literally selected few items in the Selected LMC choice list and hit save then I have the items in the Model.Which is fine, but as a user he has done that act already so ...guess am missing something here. What I would like is for the Select LMC Model to be updated (either I do it or automatically) from the choices list. Has anyone used this in the way I am using it? How do we get around this? Thanks in advance. Cheers
