Hi Guys I have a Jscript which filters a picklist based on a condition, the filter actually works in the CRM 2013 Mobile app, but after the record is saved and reopened the Picklist field goes blank? The selected option is saved to the database as I checked the desktop client, so something in the mobile client is causing it to go blank as it works fine on the desktop version? Anybody aware of any specific JScript issues for the Mobile app?
Im using the below Dependant code for passing my Picklist filters to;
//If the SDK namespace object is not defined, create it.
if (typeof (SDK) == "undefined")
{ SDK = {}; }
// Create Namespace container for functions in this library;
SDK.DependentOptionSet = {};
SDK.DependentOptionSet.init = function (webResourceName) {
//Retrieve the XML Web Resource specified by the parameter passed
var clientURL = Xrm.Page.context.getClientUrl();
var pathToWR = clientURL + "/WebResources/" + webResourceName;
var xhr = new XMLHttpRequest();
xhr.open("GET", pathToWR, true);
xhr.setRequestHeader("Content-Type", "text/xml");
xhr.onreadystatechange = function () { SDK.DependentOptionSet.completeInitialization(xhr); };
xhr.send();
};
SDK.DependentOptionSet.completeInitialization = function (xhr) {
if (xhr.readyState == 4 /* complete */) {
if (xhr.status == 200) {
xhr.onreadystatechange = null; //avoids memory leaks
var JSConfig = [];
var ParentFields = xhr.responseXML.documentElement.getElementsByTagName("ParentField");
for (var i = 0; i < ParentFields.length; i++) {
var ParentField = ParentFields[i];
var mapping = {};
mapping.parent = ParentField.getAttribute("id");
mapping.dependent = SDK.Util.selectSingleNode(ParentField, "DependentField").getAttribute("id");
mapping.options = [];
var options = SDK.Util.selectNodes(ParentField, "Option");
for (var a = 0; a < options.length; a++) {
var option = {};
option.value = options[a].getAttribute("value");
option.showOptions = [];
var optionsToShow = SDK.Util.selectNodes(options[a], "ShowOption");
for (var b = 0; b < optionsToShow.length; b++) {
var optionToShow = {};
optionToShow.value = optionsToShow[b].getAttribute("value");
optionToShow.text = optionsToShow[b].getAttribute("label");
option.showOptions.push(optionToShow);
}
mapping.options.push(option);
}
JSConfig.push(mapping);
}
//Attach the configuration object to DependentOptionSet
//so it will be available for the OnChange events
SDK.DependentOptionSet.config = JSConfig;
//Fire the onchange event for the mapped optionset fields
// so that the dependent fields are filtered for the current values.
