Unable to make custom variable editor mandatory

Hi All,

We are having an issue with making fields of a custom variable editor Readonly. could you please help us in resolving it.

Issue:

We have built a custom table(x_ct_request) in our scoped application, this table extends task table.We are using SM variable editor (Global scope) which picks all the variables from the record producers and displays them on (x_ct_request) table. Now we need to make the fields on this variable editor mandatory.

Approach:1:-

I have written an on display Business rule to get all the variable editor fields in g_scratchpad and then tried to make them read only using a client script.

but i am getting an error saying "ReadOnly true not set on field variables.check_status: cross-scope access denied.".

The table on which this business rule and client script are executing are in same application scope i.e. custom application scope.

Approach:2:-

I have written a simple client script statement " g_form.setVariablesReadOnly(true);" bu this doesnt work as well.

When i alert with g_form.getValue('variables.variable_name'); i get the correct value in alert but it doesn't set to readonly I get the same error ("ReadOnly true not set on field variables.check_status: cross-scope access denied.").

Should I create a record in application cross scope access table. If yes should i create it for the formatter table or only for the formatter which is used as variable editor.

Please suggest me a correct approach   if i am going wrong.

Waiting for your reply.

Thanks and Regards,

Zabeeulla.

hi Shishir,


I have tried to check the can create and update check boxes for formatter and macro tables so that a cross scope access record gets created . No luck i am still facing the same issue. I get the same error and variables on variable editor are editable.

You might have to do this the dodgy way (not best practice)

However, if you take this route, you won't be able to get your app certified.

Hi Paul,



We cant try this because the same should reflect on Service portal as well   and i dont think   "var ve = $('variable_map').up('table');" is supported on Service portal.


I have tried creating a scoped formatter and attacehd a custom macro, but it doesnt get displayed on the form.what could be the reason.



Method:



I have copied existing global ui macro and created a new one in my application scope.


created a new formatter and attached the new macro to it.


It is hidden i only see a seperation line instead of a variable editor.
