AW: AW: Problem with evaluation of Tomahawk HtmlSelectOneRadio components inside UIData (programmatically created UI)
There's a use case where I encounter a problem with my solution. When a validation error occurs in the process validations phase, all the radio buttons shown in the HtmlDataTable aren't rendered when the page is redisplayed. Why I try to evaluate the HtmlSelectOneRadio components in this view state, I get a runtime error because the components aren't fully initialized. The component values / value classes are of the following type, for example: value = [EMAIL PROTECTED] value class = org.apache.myfaces.renderkit.RendererUtils$1 Is it possible to solve this problem, or is this a dead end?

Hi Matthias,
i created a small test page (see attached files), but i can't reproduce
your problem. All works as expected, also when validation fails.
Please provide more info about what you are doing and your tree structure.

I get a runtime error because the components aren't fully initialized. The
component values / value classes are of the following type, for example:
value = [EMAIL PROTECTED]
value class = org.apache.myfaces.renderkit.RendererUtils$1
Is it possible to solve this problem, or is this a dead end?

Hi Volker! Thanks for your support. I'm not sure, but maybe you should try throwing a javax.faces.validator.ValidatorException in your validation method when your validation fails. I don't use a validation method. I use required=true, and when nothing is entered, a standard validation error occurs displaying the same view again. My tree structure depends on the survey that is shown to the user. In my example where the error occurred, there have been two data tables with some rows of radio buttons and other components for other question types, e. g. 2 HtmlSelectOneMenu, 4 HtmlSelectManyCheckbox, some HtmlInputText and HtmlInputTextarea. The components are all children of the one form used in the view. All works fine, except when a validation error had occured, so please try with a standard validation error.

So what you're really looking for is the functionality I implemented a few weeks ago for findComponent, to return a properly initialized component for this row.

I wonder about that, because processing the user input after locating the components by using findComponent works for all the other question types I use (without UIData), e. g. by using - only one HtmlSelectOneRadio component and some HtmlRadio components, - only one HtmlSelectManyCheckbox component and some HtmlCheckbox components, - only one HtmlInputText or HtmlInputTextarea Has this sth. to do with UIData?

Februar 2006 23:05 An: MyFaces Discussion Betreff: Re: Problem with evaluation of Tomahawk HtmlSelectOneRadio components inside UIData (programmatically created UI) Ok, I do think I know now what your problem is: the findComponent will deliver a component which is not properly initialized (it will return the stamp, but not the actual initialized component for this row...) So what you're really looking for is the functionality I implemented a few weeks ago for findComponent, to return a properly initialized component for this row. But: I can't help you out with fixing this in the radio-renderer right now, sorry. And you're in stress, too, to get your thesis finished, right? So I really don't know how to fix this. no clue. Anyone else able to help? regards, Martin On 2/8/06, Matthias Kahlau [EMAIL PROTECTED] wrote: Hi Martin!
