Hi All,

I had a requirement that I need to pass a JSON string through a input property while registering the control on field. In the control manifest, I defined a input property "GroupingOptions" with type as "Mulitple". The problem came up when I'm passing json string with more than 100 characters it's truncate upto 100 characters, but as per the documentation property of type 'Mulitple' accepts upto 1,048,576 characters and I tried with SingleLine.Textarea(accepts upto 4000 characters) too, got the same result. So, I'm wondering here that am I miss something or is it a bug?

Property Definition in Control Manifest file.

<property name="GroupingOptions" display-name-key="GroupingOptions_Display_Key" description-key="GroupingOptions_Desc_Key" of-type="Mulitple" usage="input" required="false" />

Can anyone please help me here...

I have noticed that maxlength attribute on input property field is fixed to 100 characters for textarea and multiple types.

It's a bug from microsoft end, hope it will be fix in next release. The workaround will be the update of maxlength attribute from the inspector as required but it should be less than 4000 for SingleLine.TextArea and 1,048,576 for multiple types.

We have identified this to be a bug in the form designer and for reference it is tracked via internal ID 1485549 .

Note that these control configurations are added to the form XML so needs some dilegence in terms of how much data should be passed/stored via control configuration. Another alternative is to have this data stored in some config entity and get it via webAPI. Control can store it locally using setcontrol state for better performance.

Update 10/29/2021 : The fix is checked in and users should be able to add strings upto 2000 characters in legacy designer. New form designer will have updated limit as specific PCF type support is incrementally added there.

Yes, it's still a known issue. There is a new release due in the near future where helpfully it will be fixed (I don't know, merely hope) but it's been delayed by the corona virus.

Sadly no easy one.

I looked at using an environment variables but most of the time we need a control entity to manage what is being shown in that circumstance doing so we keep the appropriate details in there. It does mean we have a couple of "light" versions of a controls that we won't be releasing but I beyond that I can live with it.
