Re: Synchronizing AutoCompleteTextField with a checkbox
That would work as well, yes. I don't know if this is good practice, but the
way I've done it now, which works, is:
tsf = new TableSelectionField("TableNameAutoCompleteTextField");
AjaxCheckBox tncb = new AjaxCheckBox("TableNamesRegexpCheckBox")
{
public void onUpdate(AjaxRequestTarget target)
{
//squelch! does nothing
}
};
tsf.setRegexp(tncb); //don't know if this is good practice, but works
In the model I have methods:
public void setTableNamesRegexpCheckBox(boolean b)
{
this.b_tablenames = b;
}
public boolean getTableNamesRegexpCheckBox()
{
return b_tablenames;
}
public String getTableNameAutoCompleteTextField()
{
return s_tablenames;
}
public void setTableNameAutoCompleteTextField(String s)
{
s_tablenames = s;
}
And in the getChoices method for the textfield I have the following logic:
if((Boolean)regexp.getModelObject())
{
//regular expression
}
else
{
//normal
}
Cheers

Re: Synchronizing AutoCompleteTextField with a checkbox
I'm a dumdum.
The answer is to use AjaxCheckBox (duhh)

Synchronizing AutoCompleteTextField with a checkbox
Hi
I have an autocomplete field object with the getChoices method overridden,
which works just fine. Next to it I have a checkbox, which when checked
alters the logic in getChoices so that the string is interpreted as a
regular expression.
This DOES work:
tsf = new TableSelectionField("TableNameAutoCompleteTextField");
subjcb = new CheckBox("SubjectsRegexpCheckBox")
{
protected boolean wantOnSelectionChangedNotifications()
{
return true;
}
};
both components are added to form, so they implicitly get the
CompoundPropertyModel.
Right, that's wonderful - except now when I click the checkbox the entire
page refreshes. When there's lots of stuff on the page this can be a heavy
operation. So I took this bit out:
subjcb = new CheckBox("SubjectsRegexpCheckBox")
{
protected boolean wantOnSelectionChangedNotifications()
{
return true;
}
};
And now the autocomplete field does not work - well, not completely. If I
click submit on the form (which gets that state of the checkbox and field) I
get the expected results, even if the autocomplete field doesn't populate
correctly.
Is there any way I can get round this without forcing a refresh when i click
on the checkbox?
Cheers
WK

Scrollbars on AutomCompleteTextField?
Hi all Has anyone managed to put scrollbars on the drop-down bit of an AutomCompleteTextField? Seems that i have loads of things beginning with "t" so the explorer window's scrollbars compensate, which isn't ideal because there's other stuff on the panel. I'm guessing its something to do the IAutoCompleteRenderer?

Re: Non-serializable objects and efficiency
Thanks for prompt reply.
Yes, I was thinking having 1 DataConn for every new request. So what i
envision is:
1. User goes to home page ("active window" being the browser window)
2. On connection, a new DataConn object should be initialised.
3. User does data enquiry stuff from that page (lots of tabs, form inputs
etc.) - components on the page are populated by making requests to DataConn.
Otherwise I could have just 1 DataConn for the entire application but it
might get a bit loaded if there are lots and lots of people connecting -
plus it does user authentication via the contructor so there has to be 1
DataConn per user.
Thanks for your help so far!

Re: Non-serializable objects and efficiency
Hi Thanks... Then how do I get that object by it's id? (did you mean component id?) I guess what i'm asking is how to best structure things in Wicket when there is a resource that isn't serializable and is used by multiple components. So in my case I have a number of tabs, each with its own panel. Within the panel there's a bunch of fillable components, e.g. tables, which are populated by using DataConn. However for every person that visits the site there can only ever be one instance of DataConn (so there would be multiple instances in the application if more then one person is hitting the home page). Another question: DataConn should also be "wrapped up" so that GB can deal with it once a user closes the active window. Is there a way to do this? I keep coming back to the idea of Sessions here but I have a gap in my understanding of how wicket is deploying objects here. Any help, much appreciated. Thanks! WW.

Non-serializable objects and efficiency
Hi I'm new to Wicket to this might be an ultra-dum question :) I'm creating a wicket application that gets its data from an online resource. The connection logic to that resource is in an external jar and most of those classes don't implement Serializable. Fore ease of explanation, let's call the entry class for the connection "DataConn". So whenever I want to get specific data to, say, fill in an AutoCompleteTextField all i do is list=dataconn.getStuff(). Moreover, whenever someone comes to the application's homepage they shoult only ever have ONE instance of DataConn, i.e. 1 instance for each "user". So my question is - what's the best way to go about doing this in Wicket? I am aware of Session and Models in wicket (though my understanding is poor) - could anyone direct me to the appropriate examples or suggestions please? Thanks WK. -- View this message in context: http://www.nabble.com/Non-serializable-objects-and-efficiency-tf4684047.html#a13384755 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
