Can I write to a session variable from within a scoped app?

brianrichards · ‎08-07-2017

Here is my problem:

I have created a custom table within a scoped app, and I have added a UI action to show a link on the form for this table in order to launch a specific record producer. In the UI action I have the following script:

var url = 'com.glideapp.servicecatalog_cat_item_view.do?sysparm_id=683d4adf0f4c43006a4a419ce1050e91';

gs.getSession().putClientData('room',current.sys_id);

action.setRedirectURL(url);

This UI Action fails to execute (drops me back to the list view without redirecting.)

If I create this exact same UI Action in global against a global table, it executes fine and the session variable 'room' is available for me to 'getClientData()' from the record producer.

From this I have guessed that I cannot putClientData() from within a scoped app.

First of all, WTH. Secondly, is there an alternative that would allow me to pass a value from a UI action to a record producer so I can do something nice and simple like populate a record producer field?

Thanks for the help!

Hi Brian, Did you solve your issue? In a case that someone would need a solution; I've just finished an implementation for scoped application using sessions;

My goal was to pass current sys_id to "scripted filter" used in report

My solution:

1) UI Action :

var session = gs.getSession();

session.putClientData('sysID', current.sys_id.toString()); //!!!! IMPORTANT need to pass string

var published_url = '/sys_report_display.do?sysparm_report_id=8c4e773adb300300e1dc72ffbf961949';

action.setRedirectURL(published_url);

my script include:

client callable: true

name: getCurrentEvent

Script:

function getCurrentEvent(){

var session = gs.getSession();

var event = session.getClientData('sysID');

//session.clearClientData('sysID');

return event;

}

or to get session values in client side:

create client script onLoad and call var v = g_user.getClientData('sysID');

Hi Brian,

Any idea how to get getClientData in server side?
