So I just set out to prove you wrongalas, this time I tried it and it worked. Damn, wrong again - that's twice this year! Netx time, Scott, try and make it sound a little more complicated.

RE: IPropertySelectionModel - what they don't write in the documentation
Hi Murray,
An int to a short is fine, but an Integer doesn't translate to a Short. You
just need to change your methods in your selection model to return Short
objects, rather than Integer objects.

Scott

Subject: IPropertySelectionModel - what they don't write in the
documentation
Date: Fri, 9 Feb 2007 04:39:13 + (UTC)
Hello tapestry experts
The API documentation for IPropertySelectionModel is lacking key
information.
In particular how the initial value is defined.
What it should say is stuff like:
"To set the initial value of the HTML select element you need to bind a
value to
this control. The type of value bound is important [This is where
somebody
else needs to take over.]"
I have spent all day trying to initialise a value in my HTML select
element. I
had searched through the lists and the web but I didn't find anything like
what
I was experiencing. Check out this:
I had a static list of security levels:
private static final String[] textOptions = new String[]{
"(none)",
"Quoting",
"Ordering",
"Shop manager",
"Manages all shops",
"Office staff",
"Administrator"
};
and some standard functions in my selection model:
public int getOptionCount() {
return textOptions.length;
}
public Object getOption(int index) {
return new Integer(index);
}
public String getLabel(int index) {
return textOptions[index];
}
public String getValue(int index) {
return String.valueOf(index);
}
public Object translateValue(String value){
return Integer.parseInt(value);
}
and very normal stuff in my .page file:
All of this I had done before and everywhere else it was working fine. But
suddenly this one didn't work. Then it occured to me, maybe the value from
user.security wasn't being passed correctly.
public void setSecurity(short security) {
this.security = security;
}
public short getSecurity() {
return security;
}
It's a short! Okay, so how does that affect setting the initial value for
my
select. I read through the documentation over and again, search the lists,
absolutely nothing. It shouldn't affect it. My other examples were of
type
'int' and my guess is that Tapestry would cope with translating a short to
an
int - not a chance. I tried adapting the translateValue() function to
return
Short.parseShort(value) but this still didn't work. What else am I
supposed to
change???
It appears that IPropertySelectionModel only works with integer values! I
finally made a work around that looks like this:
and
public int getSecurityint() {
return (int) security;
}
public void setSecurityint(int sec) {
this.security = (short) sec;
}
How sad is that!
Okay, what should I have done?
Cheers
Murray
