DatePicker: View "year" throws error on year selection

[tibramo]

Describe the bug

The DatePicker with view "year", as in https://primevue.org/datepicker/#yearpicker, throws the following error upon year selection:

ReferenceError: value is not defined
    at Proxy.isYearSelected (DatePicker.ca76d316.js:358:8960)
    at year (DatePicker.ca76d316.js:358:2021)
    at Go (entry.8d61df7a.js:36:124976)
    at Dm (entry.8d61df7a.js:36:125192)
    at Proxy._getOptionValue (BaseComponent.54c219ea.js:1:4811)
    at Proxy.cx (BaseComponent.54c219ea.js:1:6791)
    at DatePicker.ca76d316.js:370:14830

    at DatePicker.ca76d316.js:370:14698
    at Object.r [as default] (entry.8d61df7a.js:16:3695)

After encountering this error, you cannot open the DatePicker again unless you manually clear the input field.

I have also a same issue but one error is more when this (1st image) error come after that if we select any date then that time it gives a contineos loop of vue warning in console like (2nd img) , to remove this we have to only refresh 1st image

2nd image

I've the same probleme :

If i initialise my model with new Date() i have error. If i don t define my model, everything is ok.

This is a fundamental bug that can be easily reproduced by going to the datepicker page and selecting a value. If you try to click on the year you will be prompted with the error above.

Given there's a PR to try and address it, is it possible to include in the upcoming versions? Thanks!

@tugcekucukoglu please could you take a look at this bug, the open PR seems to fix the issue. Would be great to get it in a 4.0.2 release

[gustavobmichel]

I know this workaround might not work for everyone, but we have disabled the year selection via a css rule.

.p-datepicker-select-year {
  pointer-events: none;
}

We are working very hard to upgrade to PrimeVue 4 and having to rework the theme system so this will unblock us for now until we have a fix.

Hi, Allan here! I'm from Guatemala and I'm working with the government as tech lead, currently we have the same problem specifically with the "Only Year Picker", Do you have any update about this issue? Thanks you so much.

[alegMINTRAB]

I agree with Rodriguez Ae. Currently we are working on a platform that relies on a PrimeVue frontend. And this is currently an on going issue with different projects at the Government.

Hi, I urgently need to use the date picker only in Years if we could get an update on the issue it would be great.

[MynorSaban]

We are developing a platform with PrimeVue and have encountered the same issue with the "Only Year Picker"

[dinacuatro]

Have exactly the same problem, also need urgently the date picker to work in years mode, any due-date for fixing this bug?

hello i did this to make it work for the moment it has date format "yy" and the view is in month.

@cagataycivici not sure if @tugcekucukoglu is away but please could we get this looked at? There is a PR with a fix that is ready for merging which would help a lot of us out!
