I am new to zk and am having trouble with this. I have a textbox for a filename with a 'browse' button next to it which will open another window (below).I am having trouble passing the textbox (object or path) to the controller of the new window. I want it to set value of the original textbox after user selects something from tree in popup window. What is best way to pass it to the 2nd window's controller. I don't want to hardcode a path to the textbox because I want to reuse the popup's controller elsewhere. Thanks for any help!

Button creating new window:

    public class SaveFileTabpanelController extends SelectorComposer<Component> {
    private Window window;
    @Wire
    Textbox filenameTextbox;
    @Listen ("onClick = #browseBtn")
    public void onClickBrowseBtn() {
        String template = "browseFolder.zul"
        Map<String, Object> args = new HashMap<String, Object>();
        args.put("testString", "test string 1");
        args.put("textbox", filenameTextbox);
        window = (Window)Executions.createComponents(template, null, args);
        window.doModal();
    }
}

new window zul:

    <window id="browseFolderOuterWin" title="Select a folder" 
height="500px" width="400px" 
apply="com.namsi.eztab.services.BrowseFolderController">
    <borderlayout>
        <north>     <label id="testLbl" value="123"/>
        </north>
        <center border="0">
                <tree id="foldersTree" style="height:18px;"
                       width="100%" vflex="true">
                    <treecols sizable="true">
                        <treecol width="100%"/>
                    </treecols>
                    <treechildren>
                    <treeitem>
                    <treerow>
                    <treecell label="${arg.testString}" >
                       <attribute name="onDoubleClick">
                        testLbl.setValue(self.getLabel() + "rk");
                       </attribute>
                    </treecell>
                    </treerow>
                    </treeitem>
                    <treeitem>
                    <treerow>
                    <treecell label="dir 2"/>
                    </treerow>
                    </treeitem>
                    </treechildren>
                </tree>
        </center>
        <south border="0">
            <hbox width="100%" pack="center">
                <button id="closeBtn" label="Close" />
            </hbox>
        </south>
    </borderlayout>
</window>

controller of new window:

    public class BrowseFolderController extends SelectorComposer<Component> {
        private Window window;
        String testString2 = null;
        @Wire
        Window browseFolderOuterWin;
        @Listen ("onClick = #closeBtn")
        public void onClickCloseBtn() {
            System.out.println(this + " detaching, testString2 = " + testString2);
            browseFolderOuterWin.detach();
        }
