PropertyEditors arent' called when *rendering* jsps.

[Colin Yates]

Hi all,

When I register a propertyEditor, it is only ever called when binding, i.e. when converting request parameters to Objects. It never seems to be called when rendering the jsp.

This is as I would expect because it gives me the most flexibility. Pain for dates because you have to have the formatting in two places.

Anyways, a couple of other posters seem to think that property editors *are* called when rendering jsps.

Can someone from the spring team please put my mind at ease before I go insane and question reality Are propertyEditors called when *rendering* jsps.

Ta.

OK, seems I *have* been a bit of a plonker

It appears getAsText *is* called when rendering when used within spring:bind . I think I got horribly confused because property editors are only called within spring:bind tags, not just in "normal" jstl.

Doh!

Apologies to all posters that had to put up with me ranting that propertyEditors were *not* called on rendering

Yatesco,

i'm desperatly trying to have some propertyEditor called when rendering when used within spring:bind. how did you register your propertyEditor (i tried to simply register it to the binder object in overriding method of initBinder of SimlpeFormController, but with no success)?

thanks,
Mati.

Try overriding

SimpleFormController.initBinder(HttpServletRequest request,
                          ServletRequestDataBinder binder);

actually the method is in BaseCommandController but I assume you are using SFC

You will basically want to call one of the

registerCustomEditor

methods (check the javadoc for more info.) on the binder.

Thanks a lot for your quick reply.
Actually i had already done exactly what you are suggesting (see my previous post).
Maybe i'll be more specific - i have a map(representing the application configuration parameters) whose keys type is of my own enum type. The map values are just of type object. I want to have a form representing this map.
As for my form command object, i'm using some MapCommand object that holds the original map

public class MapCommand {

    private Map map;

    public void setMap(Map map) {
        this.map = map;
    }

    public Map getMap() {
        return this.map;
    }
}

The map keys are of type ConfigParam -

public enum ConfigParameter {

    activeAlertsExpirationDays(7);

    private Object defaultValue;

    private ConfigParameter(Object defaultValue) {
        this.defaultValue = defaultValue;
    }
    public Object getDefaultValue() {
        return defaultValue;
    }

in my jsp form i want to use something like this...

<spring:bind path="command.map['activeAlertsExpirationDays']">

...but it doesn't work
Is there a way to use spring BindTag for binding form fields to map-entries whose keys are not strings?

[Colin Yates]

Ah, that I am not sure off I imagine you could do something like this, but I am not sure:

  <spring:bind path="command.map[${myObj}]">

but I am just guessing.

Sorry

Hi yatesco,

I´m using a MultiActionController... I´ve put a command in the ModelAndView, but I´m having problems with rendering Date´s.. It seems the PropertyEditor is not used at the jsp... Looking the code for the BindTag I´ve noted that a BindStatus only receives a PropertyEditor when there are erros... I´m missing something???

Thank you so much!
