Webresource - Value is not an array

Report

Posted on by sscinokc

Let me say up front....I am unfamiliar with arrays and do not know/understand the concept and how to define or create them.

I have a "partners" type field from a custom activity that I am attempting to hide based on a Mandated (value "0") or Non-mandated (value "1") option set field. Using the following code in on-load and on-change web-resource, I keep getting the error message "Value is not an array". Can someone please help.

function HideMandate_Lookup() {

var mandated = Xrm.Page.getAttribute("statemandated").getValue();

   if (mandated != 0) {
   Xrm.Page.ui.controls.get("partners").setVisible(false)
   Xrm.Page.getAttribute("partners").setValue(false);

}

else if (mandated == 0) {
   Xrm.Page.ui.controls.get("partners").setVisible(true)
   Xrm.Page.getAttribute("partners").setValue(true);

}
}

Hi,

You could try a business rule instead.

Hello,

Is "partners" field is a multiple select value field? be cause if so Xrm.Page.getAttribute("statemandated").getValue() will return an Array and since you are comparing it to a number i think that may cause that error.

I Hope this helps :)

Hi,

1)Did you debug that code and find that what value you get in mandated variable ?

2) You have any function other than this HideManadate_lookup function in same web-resource file. may be it will occur this issue.

3) Add Semicolon too in Xrm.Page.ui.controls.get("partners").setVisible(false) and Xrm.Page.ui.controls.get("partners").setVisible(true) for just code ethics.

4) Any other function call in page load or onchange other than this.

Let me know it helps or not What value you are getting in mandated variable when you debug

Thanks

Ajyendra

Ketan - Tried that first. However, "Party List" fields are not available to select from in Business Rules.

Hi,

You cannot set true/false in a partylist.

Refer below example.

var Partners = Xrm.Page.getAttribute("partners");

var value = new Array();

value[0] = new Object();

value[0].id = "67cf851f-165a-e611-80bb-a4934caa8811";

value[0].name = "Helpdesk";

value[0].entityType = "systemuser";

Partners.setValue(value);

If you want to clear then use below.

Xrm.Page.getAttribute("partners").setValue(null)

Regards,

Ketan

Ketan -

Thanks for the response. I understood your comment about true/false not allowed in partylist. The rest was unfamiliar language to me at this point and I will have to do further "learning" about arrays to know how to apply.

In the mean time, I heard elsewhere someone having this difficulty and elected to apply their solution of simply placing the partylist in its own Section, and just hid the Section based on my criteria. That seemed to do the trick for now until I can learn more about adding an array.

Thanks for your help.

Hi,

You need to pass an Integer value for SetValue.

Thanks, Kalpavruksh, for pointing me in the right direction. It helped me understand that I did not require the Xrm.Page.getAttribute("partners").setValue line at all. Once I took those lines out to be the following, it worked perfectly. Thanks again.

function HideMandate_Lookup() {

var mandated = Xrm.Page.getAttribute("statemandated").getValue();

if (mandated != 0) {

Xrm.Page.ui.controls.get("partners").setVisible(false)

}

else if (mandated == 0) {

Xrm.Page.ui.controls.get("partners").setVisible(true)

}

}
