Hi,

Why can't you use an import variable of "lchr" which can store more number of characters.

From webdynpro sent , a string from the textedit /textview and pass that to backend ,and update it .

In backend , If you want to store some string of more characters you do like this ,

Create 2 fields in the table.

The first field should of type ssize - INT4.

Second field should be of type str - LCHAR.

suppose u if set ,

ssize = 1000 .

str = "any number of characters......upto 1000 it will take"

See whether is it ok with your requirement.

Thanks ,

Hello saranya,

Why can't you try by setting the size of the commentVariable data element property to char 255 and in front-end Text Edit control; set the maximum size of text( comment) allowed to 255. ( you can use the mouse enter action to check the length of the text that is entered)

It has to work.

Hi ,

loop the String attribute holding the comments filed.

Break the String in to 255 length Strings and Send them to Internal table as rows.

When displaying them Loop through the table Concatenate the Strings and display in a TextEdit feild.

		String data = wdContext.currentContextElement().get<att>();
		String subData = null;
		int startIndex = 0;
		int endIndex   = 256;
		
		while(data.length()>0)
		{			
			if(data.length()<=256)
			{
				endIndex = data.length();
			}
			else
			{
				endIndex = 255;
			}
			
			subData = data.substring(0,endIndex);
			
			if(data.length()>0)
				data = data.substring(endIndex);

                                          //create new element and set the subData string to it
                                            element = wdContext.create<data>Element();
                                           element.set<att1>(subData );
                                          input.add(element);
