Re: How to convert component model object to rendered HTML?
Guten Tag Martin Grigorov, am Donnerstag, 5. März 2015 um 08:47 schrieben Sie: You can call formComponent#clearInput() in #onError() callback method. This way Wicket will use the last (valid) model value. This way I would loose the current input of the user? You can also set custom model value in #onError() if you need. My model needs to be a list of unique IDs, I can't change that to a list of non unique company names. Looks like I would need something simple like overriding FormComponent.getValue, which is final... Who does call this method during the render process? I couldn't find the place, maybe I can hook the caller.

Guten Tag Thorsten Schöning, am Donnerstag, 5. März 2015 um 18:57 schrieben Sie: Looks like I would need something simple like overriding FormComponent.getValue, which is final... I found a simple workaround for me: Override onInvalid and getInputAsArray, in onInvalid I set an instance flag to note it was called, call inputChanged and reset the flag. inputChanged calls getInputAsArray (currently), which I overridden to respect my flag, in which case I provide my company names instead of the ids. The current model with ids is available using getConvertedInput and because auf the validation errors the changed raw input doesn't move forward into other wicket internals, but only gets rendered in the output. I know it's hacky, but that's exactly what I need. :-/ Mit freundlichen Grüßen, Thorsten Schöning -- Thorsten Schöning E-Mail: thorsten.schoen...@am-soft.de AM-SoFT IT-Systeme http://www.AM-SoFT.de/ Telefon...05151- 9468- 55 Fax...05151- 9468- 88 Mobil..0178-8 9468- 04 AM-SoFT GmbH IT-Systeme, Brandenburger Str. 7c, 31789 Hameln AG Hannover HRB 207 694 - Geschäftsführer: Andreas Muchow - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
How to convert component model object to rendered HTML?
Hi all, I have my own subclass of RequiredTextField for very specific reasons and need to convert input after form submit to a Wicket model and vice versa from a Wicket model to a form input value in case of errors and such, when Wicket renders the form with the current values. I have overridden Component.getConverter and can see that convertToObject of my implementation is called, but not convertToString. Instead Wicket renders exactly that data which it got submitted by the form, but is not what I need to show to the user. Any idea on where I have a problem? Thanks!

You can call formComponent#clearInput() in #onError() callback method. This way Wicket will use the last (valid) model value. You can also set custom model value in #onError() if you need.

Some background: I have an Ajax auto complete input which searches based on company names, but sends company IDs to Wicket. If other forms on the page fail validation, I need to render the former searched company names instead of their IDs back into the form. Wicket by default renders IDs, because that's what it gets, but I thought I can simply change that on the server during the render process somehow back to company names.

FormComponent have two models - the model that every component has and input (raw converted). During form submit processing the raw input (the request parameter as String) is converted to the type of the model, here #convertToObject() is used. Next step in the processing is validation, the converted input is given to all registered IValidators and if all checks pass then finally the converted input is set as a model object/value. If the validation fails then the *raw* input is rendered to the user and there is no usage of #convertToString() because there is no need.
