For your text field, you can use an onLoad client script to set the width in pixels. Adjust the number as needed.

g_form.getControl('variable_name_of_text_field').style.width = '200px'; //Set the width of a field

Info from Share (i have attached the files as well):

With this update set I have setup a widget that you can apply to a catalog variable to create a dynamic input table of information. This widget gives flexibly in setting the title, columns and structure of the table to input data. This table can be made to limit the number of rows or allow for the user to create an endless number of rows to input their data. In short, this gives you the ability to create a spreadsheet type of variable for users to input their data.

When the request is submitted the table data is written into an HTML variable for display on request items along with a JSON variable that can be used for processing the raw data. I set this up so that you can use the widget both for display of the variable table but also edit the definition when you are logged on as an administrator.

Hello Lars,

You are awesome..It was a perfect solution and really helpful and it saved a lot of time.

I have one doubt here,How can I pass the data which they created dynamically in the variable to transfer in the incident?

Thanks

I have never used it my self, so I am just quoting the documentation

You map the output of the table to two variables. One containing and rendered HTML and the other the content in json.

If you use this functionality in a record producer, you need add logic to your processing script and map the JSON to the incident.

Alternatively you can simply map the "html_output" to the work_notes field. Then the HTML version of the table should be shown in the activity stream.

Hello Lars,

I tried to map the html_output to work_notes field,

But its now no luck

You probably need to wrap the html in a [code] tag - see Change Additional Comments and Work Notes to HTML?

current.work_notes = ("[code]" + producer.html_output + "[/code]" );

Its looking fine HTML wise - the "undefined" is comming from the widget - I don't know if you haven't set it up correctly - can't help you with that

Hello Lars,

Really sorry for asking the question again.

I want to map this variable via script include or BR. producer(current.work_notes = ("[code]" + producer.html_output + "[/code]" );) won't work there.

I tried below code in the script include didn't work

var html_output=this.getParameter('sysparm_html_output');

var inc= new GlideRecord('incident');

inc.initialize();

inc.work_notes=html_output;

I tried below code in the before insert business rule it also didn't worked

current.work_notes = ("[code]" + current.html_output + "[/code]" );

You only have access the the variable within the record producer. After the incident is created you wont have access to it any more if you have not mapped it to a field in the incident.

Can you explain to me the business logic you are trying to implement?

Hello Lars,

I have two type of incidents.

First call resolution Incident

Working Incident.

For FCR Incident when user select the option it will get resolved in the backed and working incident am OOB submit button.

On my custom submit button am calling a script include and get it resolved.

Thanks
