How to run the activiti source code?

[balaji1]

Hi,

1. We have checked out the source code from SVN and installed in SVN.
Can you please tell us how to build this source code?

ALso what will be the outcome of this process?

2. We have proposed to use activiti plugin for our porject. We need to customise the palette shapes and XML tags. Can you please tell us the process to perform.


Please help us to resolve to above issues. We are badly stuck up here.

Tiese,
Here is  the classs and made corresponding changes to other classes as well.

package org.activiti.designer.property.extension.field;

import java.lang.reflect.Field;



import org.activiti.designer.integration.servicetask.PropertyType;
import org.activiti.designer.integration.servicetask.validator.RequiredFieldValidator;
import org.activiti.designer.property.PropertyCustomServiceTaskSection;
import org.eclipse.bpmn2.ServiceTask;
import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.CCombo;
import org.eclipse.swt.events.FocusListener;
import org.eclipse.swt.layout.FormAttachment;
import org.eclipse.swt.layout.FormData;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.ui.views.properties.tabbed.TabbedPropertySheetWidgetFactory;

/**

*/
public class CustomPropertyComboFields extends AbstractCustomPropertyField {


private CCombo comboControl;
final String[] ITEMS = { "111", "112", "113", "114", "115"};

  public CustomPropertyComboFields(final PropertyCustomServiceTaskSection section, final ServiceTask serviceTask, final Field field) {
    super(section, serviceTask, field);
  }

  @Override
  public PropertyType getPrimaryPropertyType() {
    return PropertyType.DROP_DOWN;
  }

  @Override
  public void refresh() {
    comboControl.setText(getSimpleValueFromModel());
  }

  @Override
  public String getSimpleValue() {
    return comboControl.getText();
  }

  @Override
  public Composite render(final Composite parent, final TabbedPropertySheetWidgetFactory factory, final FocusListener listener) {

    final Composite result = factory.createFlatFormComposite(parent);
    FormData data;

    comboControl = factory.createCCombo(result,SWT.BORDER_SOLID);
    comboControl.setEnabled(true);

    if (getPropertyAnnotation().required()) {
      addFieldValidator(comboControl, RequiredFieldValidator.class);
    }

    if (getPropertyAnnotation().fieldValidator() != null) {
      addFieldValidator(comboControl, getPropertyAnnotation().fieldValidator());
    }

    comboControl.addFocusListener(listener);
   
    comboControl.setItems(ITEMS);

    data = new FormData();
    data.left = new FormAttachment(0);
    data.top = new FormAttachment(0);
    data.right = new FormAttachment(100);
    comboControl.setLayoutData(data);

    return result;
  }
}

But in the above progra,, it goanna return the same list of values for all the properties. I do  not want this.

Thanks

If you need different options, then the best way to go, as with other components, is to add an annotation to the integration library that allows you to specify the list of options on the CustomServiceTask. That's what I'll be doing for the "official combobox". In that case you code is generic and you can instruct it for each property field.

Tiese,

Can you please help me to set up checkbox with any of the proprties.
I tried searching in SWT widgets tutorial and got the below code.

Display display = new Display();
    Shell shell = new Shell(display);
    shell.setLayout(new GridLayout(3, true));

    // Create three checkboxes
    new Button(shell, SWT.CHECK).setText("Checkbox 1");
    new Button(shell, SWT.CHECK).setText("Checkbox 2");
    new Button(shell, SWT.CHECK).setText("Checkbox 3");

    shell.pack();
    shell.open();


But it throws exception at Display and not able to launch.

Thanks

[tiesebarrell]

I don't think you should be creating a new Display and/or Shell. You should use the mechanisms as used for the other components to integrate it into the PropertySection.

[tiesebarrell]

Again,

do you really need to be doing this now? These components will be in Activiti Designer at the beginning of February, so you probably don't need to create them yourself.

[balaji1]

Tiese,
Just out of curiositty,

Process to create checkbox using below syntax rite?

Button checkBox = new Button(shell, SWT.CHECK);

If we dont have to create shell. What needs to be given in place of shell?

Thanks

[tiesebarrell]

It needs to be a Composite in the PropertySection.

[balaji1]

Tiese,

Could you please elaborate it.
There is a necessity for to implement now.Thats y.

    Composite Parent;
Button checkBox = new Button(Parent, SWT.CHECK);
Will the above one suffice?
Thanks
Balaji  V

[tiesebarrell]

If the parent variable is a composite in the PropertySection, that should work, yes.

[balaji1]

Tiese,

In the proeprtysEction class

   case CHECK_BOX:
              createdCustomPropertyField = new CustomPropertyCheckboxFields(this, serviceTask, fieldInfo.getField());
              createdControl = createdCustomPropertyField.render(workParent, factory, listener);
              data = new FormData();
              data.top = new FormAttachment(previousAnchor, VSPACE);
              data.left = new FormAttachment(0, LABEL_COLUMN_WIDTH);
              data.right = new FormAttachment(100, -HELP_COLUMN_WIDTH);
              createdControl.setLayoutData(data);
              break;

I am getting null pointer exception at refresh in property section class.
