Studio problem when saving extended screen

Support
#1

Studio will duplicate form content each time when press ctrl+s(cmd+s on mac) in extend screen visual designer.
Step1, create an empty screen, then use following xml. You have to modify DC class and property names.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<window xmlns="http://schemas.haulmont.com/cuba/screen/window.xsd"
        focusComponent="form">
    <data>
        <instance id="baseclassDc"
                  class="com.company.uimodel.entity.Baseclass"
                  view="_local">
            <loader/>
        </instance>
    </data>
    <dialogMode height="600"
                width="800"/>
    <layout expand="" spacing="true">
        <tabSheet id="tabSheet">
            <tab caption="Tab" margin="true,false,false,false" spacing="true">
                <form id="form" dataContainer="baseclassDc">
                    <column width="30%">
                        <textField id="nameField" property="name"/>
                        <textField id="nameField1" property="name"/>
                    </column>
                    <column width="30%">
                        <textField id="ageField" property="age"/>
                        <textField id="ageField1" property="age"/>
                    </column>
                    <column width="40%">
                        <dateField id="birthdayField" property="birthday"/>
                        <dateField id="birthdayField1" property="birthday"/>
                    </column>
                </form>
                <hbox id="editActions" spacing="true">
                    <button action="windowCommitAndClose"/>
                    <button action="windowClose"/>
                </hbox>
            </tab>
        </tabSheet>
    </layout>
</window>

Step2, extend this screen.
Step3. open extended screen in Visual designer. Press ctrl+s(cmd+s on Mac) to save extended screen.
You will notice the ext-screen have multiple columns duplicate generated.

Using Studio 11.1 Bundle version.

Hi,

If you use screen extension and want to avoid copying parts of screen xml - you have to specify id for every element which accepts this attribute. Screen extension mechanism is based on element IDs and needs them.
In your attached layout the following elements miss IDs:

  • tabsheet’s tab
  • columns
  • buttons in an hbox

Hi Alex,

Thanks for your solution, after I specify id for those missing id elements, the issue resolved.

In this case, if any element in parent xml has no ID, Studio will try to copy that?
