For opened form input fields in the backend, the TCA property requestUpdate (https://docs.typo3.org/typo3cms/TCAReference/Reference/Ctrl/Index.html#requestupdate) is not working.

Is this a bug or a feature request?
If this is not allowed, is there a special reason for that?

could you please provide steps to reproduce? I can't get your problem from your description. RequestUpdate works for me, for example the CType of tt_content implements that behaviour.

I am using the next code through flux extension:

        <flux:form options="{group:'Custom elements'}" 
                   description="Teaser element">
            <flux:form.sheet name="content">
                <flux:field.input name="linkpage" requestUpdate="1">
                    <flux:wizard.link />
                <flux:field.input name="linktext" maxCharacters="50" displayCond="FIELD:linkpage:>:0"/>

When the linkpage field looses the focus, the backend should be reloaded, to allow the evaluation of the displayCond in the other field.

no idea about flux, sorry. RequestUpdate is not available for flexforms, too.

Have a look at https://wiki.typo3.org/Extension_Development,_using_Flexforms#Display_conditions_and_dynamic_reloading_of_form, maybe that helps.

Hi Sergio,

requestUpdate is an option within your tables CTRL section. By reading the provided flux code, this means, flux has to change the TCA on the fly which doesn't work because TCA is cached. IMHO this is a problem of flux not using the TYPO3 TCA api correctly. Please contact the support of EXT:flux.

Closing this issue for now. If you have another way how to reproduce your problem, please report to another ticket. Thank you.

Actually, requestUpdate is available as "onChange=reload" within flex form fields. And yes, InputTextElements do not handle requestUpdate / onChange at all, I stumbled upon that during my current FormEngine patch.

My patch resolves this "requestUpdate does not exist in flex forms" issue by removing it from 'ctrl' section and allowing "onChange=reload" on all fields, also outside of flex forms.

So, the issue with the input fields is confirmed, and this area needs some JS side works anyway and the issue could be solved along the way.

I'll set a "Related" flag in my patch to point to this issue.
