Drupal Forms Ajax issue disabled elements unicode fix

Job ID: 38562803

Budget: €30 – €250 EUR

I'm seeking an experienced Drupal developer with a strong knowledge of Drupal Forms and Ajax callbacks. The project involves modifying a custom form on my Drupal site to better handle form data submissions.

Key Requirements:
- Good knowledge of Ajax , (know that 3 freelancers before you already failed)
- Good knowledge of Drupal, because it is Drupal Forms and I want a non-pure-javascript solution

The site is full operational but not on Internet yet, because of some minor issues :
- disabled form elements don't keep their values when re-enabled (A1/A2/C1)
- there should be some Ajax buttons added to prefill the form (or clear) (B1)
- there is an "unicode" error (probably Drupal issue?) when inputting a special word, it crashes
- I need a logic fix : Existing saved parameters needs to be editable
- and some other minor fixes

So only apply if you are sure to fix this, because some others already over estimated their "sure i can fix this" karma and failed. Wasting their time and also mine.
Freelancer with no proven Drupal experience will be ignored.
