### Begin of the deletion Custom field `Text` is displayed as single line input but allows arbitrary length 

When a user adds a the custom field of the type `text`, and leaves the default values, that field can have arbitrary length. However, the input element is single line.

###End of the deletion Steps to reproduce

1. Begin of the insertionAddEnd of the insertion Begin of the deletion addEnd of the deletion a custom field Begin of the insertionof type `Text`End of the insertion to a work package Begin of the insertionvariant.End of the insertion Begin of the deletion variant that is of the type TextEnd of the deletion

2. Enter a Begin of the deletion very longEnd of the deletion text Begin of the insertionlonger than 256 characters.End of the insertion Begin of the deletion in the custom fieldEnd of the deletion

3. Begin of the insertionSave the work package.

4. Observe that theEnd of the insertion Begin of the deletion TheEnd of the deletion text Begin of the insertionspans multiple linesEnd of the insertion Begin of the deletion is displayedEnd of the deletion in Begin of the deletion full length inEnd of the deletion the work package Begin of the insertiondetail view.End of the insertion Begin of the deletion form, but input changes to single line once clickedEnd of the deletion

### What is the buggy behavior?

* Begin of the insertionText custom fields allow usersEnd of the insertion Begin of the deletion The field in its default configuration allowsEnd of the deletion to Begin of the insertionenter an unlimited numberEnd of the insertion Begin of the deletion input large amountsEnd of the deletion of Begin of the insertioncharacters, although they are intended for single-line input.End of the insertion Begin of the deletion text, which it should not if it's meant as a single line field.End of the deletion

* Long text Begin of the insertionvalues span multiple linesEnd of the insertion Begin of the deletion content is not cut offEnd of the deletion in the work package detail Begin of the insertionview.End of the insertion Begin of the deletion viewEnd of the deletion

* Begin of the insertionThe display and editing behavior is inconsistent.End of the insertion Begin of the deletion If the field should allow long texts, its input field should be a text area rather than a single line.End of the deletion


### What is the expected behavior?

* Begin of the insertionText custom fields have a maximumEnd of the insertion Begin of the deletion If it is meant as single line input, it'sEnd of the deletion length Begin of the insertionof 256 characters.

* Users cannot save text custom field values exceeding 256 characters.

* Existing values exceeding 256 characters remain unchanged and can stillEnd of the insertion Begin of the deletion shouldEnd of the deletion be Begin of the insertiondisplayed.End of the insertion Begin of the deletion restricted or the content cut off in the work package detail viewEnd of the deletion

* Begin of the insertionInvalidEnd of the insertion Begin of the deletion If it is meant as a long plainEnd of the deletion text Begin of the insertioncustomEnd of the insertion field Begin of the insertionvalues do not prevent changesEnd of the insertion Begin of the deletion with arbitrary length, it should switchEnd of the deletion to Begin of the insertionother attributes from being saved.

* Admins can convert textEnd of the insertion Begin of the deletion textarea after a certain threshold


The field should display it's content correctly, either way.

### Background

TheEnd of the deletion custom Begin of the insertionfieldsEnd of the insertion Begin of the deletion field "text" uses the same database column as "long text", which has formatting. It is therefore technically possibleEnd of the deletion to Begin of the deletion enterEnd of the deletion long Begin of the deletion plainEnd of the deletion text Begin of the insertionfields.

* ConvertingEnd of the insertion Begin of the deletion content. However, if this should be supported, the work package list and detail form needs amendment.

It is also possible to limit the length of the field, but as there might be installations using it in its current form,End of the deletion a Begin of the insertiontext custom fieldEnd of the insertion Begin of the deletion migration path might be needed.

### Quick fix?

It might be an easy optionEnd of the deletion to Begin of the deletion leave the length restriction untouched but

1. to change the default, which is currently "0" (unlimited) toEnd of the deletion a Begin of the insertionlong text field is irreversibleEnd of the insertion Begin of the deletion sensible value

2. to truncate the display in the the work package detail form, so it does not look brokenEnd of the deletion
