Hi!

I'm using ObjectChoiceField and been wondering is there any way we can use it to also include "hidden" value. Just like in html where we can always use <option value="0" >No email notification</option>.

public ObjectChoiceField(String label, Object[] choices, int initialIndex, long style)

Putting Object[] as value to be saved is OK, but that value must also be readable by human and it just wasting bb resource to store it for future retrieval.

Or we just stuck with it? Sorry, but I'm a newbie.

you cannot use hidden values in an objectchoicefield. the field uses toString for the objects stored in it, you can either use strings or own objects that overwrite toString to provide some useful text.

Thank you sir. Do you have some sample of that code?

[simon_hain]

you want a sample for a string? or a sample for overwriting toString?

*ashame*

Issit something like this :

ObjectChoiceField myChc = new ObjectChoiceField("Choices : ", myChcOb.value.tostring(), 0, ObjectChoiceField.FIELD_LEFT)

and if i wanna read the "hidden" value, i just get it like this :

selectedVal = myChc.getChoice(myChc.getSelectedIndex());

Now, how should i create myChcOb?

I know it is more like OOP subject rather than BB.

[simon_hain · Accepted solution]

you create the field with an array of objects.

your object could look like this:

public class Bean{

private String secret;

private String description;

public Bean(String description, String secret){

this.secret=secret;

this.description=description;

}

public String getSecret(){

return secret;

}

public String toString(){

return description;

}

}

now create an array of Bean objects and initialize your field with it:

ObjectChoiceField myChc = new ObjectChoiceField("Beans : ", beans, 0, ObjectChoiceField.FIELD_LEFT)

You have sent me to the right direction, sir. Thank you very much!
