Help -- adding custom attributes to inbox

bpathakis

Hi,

I'm trying to customize our inbox, adding a custom attribute.

I've followed the instructions at:

https://community.emc.com/thread/123525?start=0&tstart=0

And it has worked, but with some issues. The columns show up in the inbox and populate with the correct data.

However, the sort link does not work for these columns (cant sort on them).

On my first try I used for the sort link (in the jsp)

<dmf:datagridTh scope='col' cssclass='doclistfilenamedatagrid leftAlignment' resizable="true">

<dmf:datasortlink cssclass='doclistbodyDatasortlink' name='sortdeqwf' nlsid='MSG_DEQWORKFLOW'

column='deqworkflow'/>

</dmf:datagridTh>

<dmf:datagridRowTd nowrap="true" cssclass='doclistfilenamedatagrid'>

String sRouterId = ((Datagrid)form.getControl(InboxList.DATAGRID_CONTROL_NAME)).getDataProvider().getDataField("router_id");

InboxDeqDataHandler Obj = new InboxDeqDataHandler();

String sWorkFlowName=Obj.getWorkflowName(sRouterId);

<dmf:label label='<%=sWorkFlowName%>'/>

</dmf:datagridRowTd>

This works to a point...the columns shows up with the correct data...but I can't sort it, and I get this error intermittently

invokeMethod() failed while calling: onClick

DataSortControl: No valid enclosing dataprovider found!

After closing this window, press the Refresh or Reload button on your browser to continue.

Usually this is after a refresh. I've also tried enclosing both in a <dmf:celltemplate> tag, but then the columns don't show up at all.

Any help or tips would be appreciated.

Below you can find the proper (but slow) example of inbox customization.

Component class (you should also modify component descriptor and jsp by adding new column definition):

public class CustomInboxClassic extends InboxClassic {

    private static final String[] CUSTOM_ATTRS = new String[] {CustomInboxAttributeDataHandler.ATTR_WORKFLOW_NAME, };

    public CustomInboxClassic() {
        super();
    }

    @Override

Thanks for your help on this.

I think I'm closer, but I'm still facing one issue:

My custom inbox class:

   private static final String[] CUSTOM_ATTRS = new String[] {InboxDeqDataHandler.ATTR_WORKFLOW_NAME, 
   InboxDeqDataHandler.ATTR_TITLE };
   
  public  CustomDeqInbox() {
  super();


  }
  
  @Override
  protected String[] getInboxAttrForDataHandler(boolean includeDocInfo) {
      String[] baseAttrs = super.getInboxAttrForDataHandler(includeDocInfo);
      String[] result = new String[baseAttrs.length + CUSTOM_ATTRS.length];
      System.arraycopy(baseAttrs, 0, result, 0, baseAttrs.length);
      System.arraycopy(CUSTOM_ATTRS, 0, result, baseAttrs.length,
              CUSTOM_ATTRS.length);
      return result;
  }
  
  @Override
  @SuppressWarnings("unchecked")
  protected void readConfig() {
      super.readConfig();
      ComponentColumnDescriptorList origColumnDescriptor = new ComponentColumnDescriptorList(
              this, "columns", getColumnsPreferenceId());
      Set origVisibleColumns = getColumnVisibility(getColumnsPreferenceId());
      for (String customAttr : CUSTOM_ATTRS) {
          if (!origVisibleColumns.contains(customAttr)) {
              continue;
          }
          ComponentColumnDescriptorList columnDescriptor = getColumnDescriptor();
          if (columnDescriptor != null) {
              columnDescriptor.add(origColumnDescriptor.get(customAttr));
          }
      }
  }
  
  protected ComponentColumnDescriptorList getColumnDescriptor() {
      try {
          Field columns = getField(getClass(), "m_columns");
          if (columns != null) {
              columns.setAccessible(true);
              return (ComponentColumnDescriptorList) columns.get(this);
          }

In my composer project I've changed the app.xml in:

webcomponent/app.xml

and changed this:


<custom_attribute_data_handler>com.documentum.webcomponent.navigation.inbox.InboxAttributeDataHandler</custom_attribute_data_handler>


 <custom_attribute_data_handler>gov.utah.deq.documentum.inboxdeq.InboxDeqDataHandler</custom_attribute_data_handler>

In inbox_list_body.jsp i've added my columns:

<dmf:datagridTh scope='col' cssclass='doclistfilenamedatagrid leftAlignment' resizable="true">

<dmf:datasortlink cssclass='doclistbodyDatasortlink' name='sort4' column="deq_work_flow" nlsid='MSG_DEQWORKFLOW' mode="text"

column='deq_work_flow'/>

</dmf:datagridTh>

<dmf:datagridTh scope='col' cssclass='doclistfilenamedatagrid leftAlignment' resizable="true">

<dmf:datasortlink cssclass='doclistbodyDatasortlink' name='sort5' column="deq_title" nlsid='MSG_DEQTITLE' mode="text"

column='deq_title'/>

</dmf:datagridTh>

Now when I restart tomcat and load the component, the inbox shows up with my columns, but in each column it says "Warning, unable to bind datafield deq_work_flow".

Do I need to add an import to the jsp?

Am I missing something?

Thanks again for the help.

PanfilovAB

Looks like you forgot to change component class in component definition.

bpathakis

Panilov,

Thanks for the help.

It's pulling up the data now and the lists are sortable.

But if I try to remove the column from the list (or re-arrange them) I get:

"CellList: aliases argument must be valid!"

My jsp tags are:

<dmf:celltemplate field='deq_work_flow'>

<dmf:datagridTh scope='col' cssclass='doclistfilenamedatagrid leftAlignment' resizable="true">

<dmf:datasortlink cssclass='doclistbodyDatasortlink' name='sort4' datafield="deq_work_flow" nlsid='MSG_DEQWORKFLOW' mode="text"

column=deq_work_flow'/>

<dmf:celltemplate field='deq_work_flow'>

<dmf:datagridRowTd nowrap="true" cssclass='doclistfilenamedatagrid'>

<dmf:label datafield='deq_work_flow'/>

</dmf:datagridRowTd>

</dmf:celltemplate>

PanfilovAB

Have you added column's definitions in component, smth. like:


<columns>
....
  <column>
    <attribute>deq_work_flow</attribute>
      <label>
        <nlsid>MSG_DEQ_WORKFLOW_LABEL</nlsid>
      </label>
      <visible>true</visible>
  </column>
  <column>
    <attribute>deq_title</attribute>
      <label>
        <nlsid>MSG_DEQ_TITLE_LABEL</nlsid>
      </label>
      <visible>true</visible>
  </column>
....

</columns>

? If yes post full error stack.

bpathakis

Panilov,

Thanks for all your help.

I managed to resolve the previous error.

Now It displays the columns, show the correct data and sorts.

The strange part now is it won't let me re-order the columns, or remove them off the list.

If i move the column up one position, it ignores it. If I move it up enough, the column doesn't display.

My sort link in jsp is like:

<dmf:celltemplate field='deq_work_flow'>

<dmf:datagridTh scope='col' cssclass='doclistfilenamedatagrid leftAlignment' resizable="true">

<dmf:datasortlink cssclass='doclistbodyDatasortlink' name='sortWF' nlsid='MSG_DEQWORKFLOW'

column='deq_title'/>

</dmf:datagridTh>

</dmf:celltemplate>

<dmf:celltemplate field='deq_work_flow'>

<dmf:datagridRowTd nowrap="true" cssclass='doclistfilenamedatagrid'>

<dmf:label datafield='CURRENT'/>

</dmf:datagridRowTd>

</dmf:celltemplate>

very confused at this point. Thanks for your help.

PanfilovAB

Try change:


protected void readConfig() {  
  super.readConfig();


protected void readColumnConfig() {  
  super.readColumnConfig();

bpathakis

Panilov,

That didn't work. Is the readconfig/readcolumnconfig method the part that handles the re-order of columns?

Is there a link to documentation for this?

Thanks.

PanfilovAB


That didn't work.

F*ck. Try this:


@Override
protected void readColumnConfig() {
    super.readColumnConfig();
    List<String> customAttrs = Arrays.asList(CUSTOM_ATTRS);
    ComponentColumnDescriptorList inboxColumnDescriptor = getColumnDescriptor();

    List columnDescriptors = getOrigColumnDescriptors();
    for (Iterator iter = columnDescriptors.iterator(); iter.hasNext();) {
        ColumnDescriptor columnDescriptor = (ColumnDescriptor) iter.next();
        String attrName = columnDescriptor.getAttribute();
        if (customAttrs.contains(attrName)
                || inboxColumnDescriptor.indexOf(attrName) > -1) {
            continue;
        }
        iter.remove();
    }
    inboxColumnDescriptor.setColumnDescriptors(columnDescriptors);
}

protected List getOrigColumnDescriptors() {
    ComponentColumnDescriptorList origColumnDescriptor = new ComponentColumnDescriptorList(
            this, "columns", getColumnsPreferenceId());
    List result = origColumnDescriptor.getColumnDescriptors();
    removeControlListener(origColumnDescriptor);
    return result;
}

changes: readConfig() -> readColumnConfig(), new method getOrigColumnDescriptors().


Is there a link to documentation for this?

I think the answer is no.

bpathakis

Panilov,

Thanks so much for going out of your way to help me. This was my first project and was a bit confusing.

It is working now.
