Multiselect lookup on a string control in SysOperation dialog doesn't hit modified method

I have a dialog created using SysOperation framework where I have two string fields with overriden multiselect lookups.

Example:

FieldA values: parent1, parent2, parent3

FieldB values: child11, child12, child21, child31, child32, child33

And when I select for example parent3, I want other lookup to be populated with values: child31, child32, child33

What I did is I have overriden postBuild method (I tried also in postRun):

dlgFieldA.registerOverrideMethod(
methodStr(FormStringControl, modified),
methodStr(MyTestUIBuilder, updateOtherLookup),
this);

But the problem is that when I select values it doesn't hit modified method at all, It only hits when I manually type the value in the field (for example parent2) and in that case it works.

How can I achieve that it hits modified when I do a selection from the lookup? Should I override some other method and not modified?

Thanks in advance

Hello, In sysoperation frmework, there is one more class, called UI builder. To acheive your expected result you need to explore this class.

Here is some reference code, (Drived from Copilot)

public class MyTestUIBuilder extends SysOperationAutomaticUIBuilder { DialogField dlgFieldA, dlgFieldB; SysLookupMultiSelectCtrl msFieldA, msFieldB; public void postBuild() { super(); dlgFieldA = this.bindInfo().getDialogField(this.dataContractObject(), methodStr(MyContract, parmFieldA)); dlgFieldB = this.bindInfo().getDialogField(this.dataContractObject(), methodStr(MyContract, parmFieldB)); // Build multi-select controller for FieldA msFieldA = SysLookupMultiSelectCtrl::constructWithQuery( this.dialog().formRun(), dlgFieldA.control(), this.queryForParents() ); // IMPORTANT: Trigger when user confirms selection in lookup msFieldA.registerOverrideMethod( methodStr(SysLookupMultiSelectCtrl, closeOk), methodStr(MyTestUIBuilder, fieldA_closeOk), this ); // FieldB controller (initially empty or default) msFieldB = SysLookupMultiSelectCtrl::constructWithQuery( this.dialog().formRun(), dlgFieldB.control(), this.queryForChildren("") // no parent yet ); } private void fieldA_closeOk(SysLookupMultiSelectCtrl _ctrl) { // Let base behavior apply the value first next fieldA_closeOk(_ctrl); // Now read selected parents and update FieldB lookup this.updateOtherLookup(); } private void updateOtherLookup() { str selectedParents = dlgFieldA.value(); // multi-select string like "parent3;parent2" depending on your setup Query q = this.queryForChildren(selectedParents); // Rebind FieldB multiselect with new query msFieldB.setQuery(q); // Optional: clear FieldB selection because available children changed dlgFieldB.value(""); } private Query queryForParents() { Query q = new Query(); QueryBuildDataSource qbds = q.addDataSource(tableNum(MyParentTable)); // add ranges/sorting as needed return q; } private Query queryForChildren(str _selectedParents) { Query q = new Query(); QueryBuildDataSource qbds = q.addDataSource(tableNum(MyChildTable)); // Apply range based on selected parent(s) // If your multi-select string uses a delimiter, parse it and apply ranges accordingly. // Example assumes child table has ParentId field. if (_selectedParents) { // simplest: if only one parent expected: // qbds.addRange(fieldNum(MyChildTable, ParentId)).value(queryValue(_selectedParents)); // If multiple parents: build an IN-style range string // e.g. (ParentId == "parent1") || (ParentId == "parent3") qbds.addRange(fieldNum(MyChildTable, ParentId)).value(this.buildOrRange(_selectedParents)); } return q; } private str buildOrRange(str _multiSelect) { // Adjust delimiter based on your multi-select format List parts = Global::strSplit(_multiSelect, ';'); ListEnumerator le = parts.getEnumerator(); str range; while (le.moveNext()) { str p = le.current(); range += range ? strFmt(" || (%1 == %2)", fieldStr(MyChildTable, ParentId), queryValue(p)) : strFmt("(%1 == %2)", fieldStr(MyChildTable, ParentId), queryValue(p)); } return range; } }

Copilot is kidding; the code wouldn't even compile. Please check the correctness of AI-generated replies before sharing them.

Note that there isn't any code needed in the UI builder to get a multi-selection lookup, because the automatic UI builder already creates UI with multi-selection for collection members of the data contract.



devgirlX, I think the actual problem is that your other lookup tries to access the string value of the original field, which is shouldn't. It should call getSelectedFieldValues() of SysLookupMultiSelectCtrl. If you're using the default framework implementation, you can call getMultiSelectFromDialogField() of your UI builder class, which returns the values as a single string, or get the SysLookupMultiSelectCtrl instance by calling multiSelectControlMap.lookup() and then calls its getSelectedFieldValues() method. It depends on what you want to do with the value.
