Hi All,
I am facing a problem with the custom property editor that, I have
written for my custom widgets.
The type of the property that I am trying to edit is a double dimension
String array. All the other property editors which are used to edit a
simple string/list are working fine. The getJavaInitialization ()' method
is called for them.
Only in the property editor with the complex data type (Double dimension
String array) the getJavaInitialization () method is not called.
getAsText ()' method is called directly and anything returned from that
method is not reflected (written) on to the code in the Editor window.
The return string from the getAsText ()' Method is of the form as given
below
return
"new String [][]{{\"ssss\",\"ssss\"}}";
The string returned from the getAsText ()'method for the property is
visible correctly as the cell value in the Properties View, but the
property is not set with that value. When I press <-|Enter key on the
cell value, I get a error message saying
IWVA0086E Error: "new String [][]{{\"ssss\",\"ssss\"}}";
Note: When I explicitly invoke the 'setValue()' method from getAsText()
method of the property editor class with a dummy value, the string is
written to the code in the editor window. But, explicit invocation of the
setValue ()' method is not advised in the API.
My custom property editor implementation is working fine in another IDE.
I have also tried clearing all the bean info cache (from
...metadata\.plugins\org.eclipse.jem.beaninfo and
...metadata\.plugins\org.eclipse.core.resources\.projects\<yourproject >\org.eclipse.jem.beaninfo).
But it is still not working.
Please please help It's very urgent:((((((((((
Thank you in advance.

Please find the code sampl below.
package mypackage1;
import java.beans.PropertyEditorSupport;
public class ContentTextEditor extends PropertyEditorSupport
{
/**
* Constructor for the ContentTextEditor object
*/
public ContentTextEditor()
{
}
public String getAsText() {
Object obj = this.getValue();
if ( obj instanceof String[])
{
return "new String[]{\"aaaa\",\"bbbb\",\"cccc\"}";
}
return ("" + obj);
}
public void setAsText(String text) throws
java.lang.IllegalArgumentException {
if (this.getValue() instanceof String) {
setValue(text);
return;
}
throw new java.lang.IllegalArgumentException(text);
}
public String getJavaInitializationString()
{
return "\""+getAsText()+"\"";
}
}

}
public void setAsText(String text) throws IllegalArgumentException {

int i = text.indexOf('/');

I'm missing something because this editor sample given here can't work.
This editor only works with "String" values, but your are trying to
return a "String[]".
This won't work because the this.value will be set to an "String[][]"
instance. So the setAsText will fail because the value is not an
instanceof String.
