Using the built in script (LiveCycle 8.2.1) to add a pair of rows to a table the script fails after one instance is added. Identical scripts just above this one execute properly.
var sSubformSOM = "xfa.form.IEP_Form.FuturePlan.frm_SDI.frm_RelServ"; // Button is not within the form to be duplicated
var bCalc = true; // Example: var bCalc = false;
var message = "You have reached the maximum number of items allowed.";
// DO NOT MODIFY THE CODE BEYOND THIS POINT - 8.2.1.3144.1.471865.466429 - Subform_Instance_Controls_Add.xfo
// Build the SOM expression of the Instance Manager using the 'underscore' syntax.
var oSubform = xfa.resolveNode(sSubformSOM); // Evaluate the SOM expression.
var sParentSOM = oSubform.parent.somExpression; // Get the parent SOM expression.
var sManagerSOM = sParentSOM + "._" + oSubform.name; // Build the SOM expression of the Instance Manager.
var oManager = xfa.resolveNode(sManagerSOM); // Evaluate the SOM expression.
var nMaxCount = oManager.occur.max; // Get the maximum number of subform occurrences allowed.
var nSubCount = oManager.count; // Get the current number of instances.
// Proceed if the maximum number of subform occurrences has not been reached.
if ((nMaxCount == "-1") || (nSubCount < nMaxCount)) {
// Invoke the Instance Manager.
var oNewInstance = oManager.addInstance(1);
// Fire the form calculations.
if (bCalc == true) {
// Execute all the form calculations.
xfa.form.recalculate(1); }
} else {
xfa.host.messageBox(message,"Add Item", 3);
}
// END OF DO NOT MODIFY
oManager in debugger "has no properties". As an app.alert(oManager) the first time thru (when it works) is an object. Subsequently it is null.
I could understand if it never worked.(?)
