table.getColumnByIndex(x).setWidth(y) fails when table created with header rows

[its-awillerding]

When running the following code, the line that sets the column width fails, if the table is created with headerRowNumber and headerColumnNumber. It does not fail if the newTable method is called only with the number of rows and columns.

setWidth fails-> OdfTable myTable = OdfTable.newTable(outputOdt, 1, 3, 1, 3);
setWidth works-> OdfTable myTable = OdfTable.newTable(outputOdt, 1, 3);

Here's an example of the code failing...

OdfTable myTable = OdfTable.newTable(outputOdt, 1, numCols, headerRowNumber, headerColumnNumber);

logItem("Template:createTable" + templateFileName + "->HeaderRow=" + myTable.getHeaderRowCount()+ ",HeaderCol=" +         myTable.getHeaderColumnCount(), Level.INFO);            
logItem("Template:createTable" + templateFileName + "->Row=" + myTable.getRowCount() + ",Col=" + myTable.getColumnCount(),
                Level.INFO);

for (Integer integer : listColumnDetails.keySet()) {
     System.out.println("Template::CreateTable Integer=" + integer + "->" + listColumnDetails.get(integer).longValue());
     myTable.getColumnByIndex(integer-1).setWidth( listColumnDetails.get(integer).longValue());
}

Output is as follows...

@its-awillerding
Could you please provide a reproducible test with a test document that we can debug?
Like in a pull request and/ or in a branch on your fork?
This will help us confirm the issue is fixed.

Thank you in advance,
Svante

Hi Svante,
I'm sorry but I'm not sure exactly what you need. I'm just opening an existing document to which I'm adding the new tables so I think any existing Writer document could work. As far as the code goes would something more generic work like the code below?

public class TestTable {

    public static void main(String[] args) {

    File outputFile = new File("test.odt");
    OdfTextDocument template = null;

    try {
        template = OdfTextDocument.loadDocument(outputFile);
    } catch (Exception ex) {
        System.out.println(ex.getMessage());
    }

    OdfTable myTable = OdfTable.newTable(template, 1, 3, 1, 3);

    // Only set the width for the first 2 columns
    for (int column=0; column < 2; column++){
         myTable.getColumnByIndex(column).setWidth(20);
    }

    try {
        template.save(outputFile);
        template.close();
    } catch (Exception ex) {
        System.out.println(ex.getMessage());
    }
  }
}

Thanks for the bug report:
The original code always used tableEle (the table:table element) when inserting/removing column elements during split. However, when columns are inside table:table-header-columns, the column element's parent is the header columns wrapper, not the table element itself. This caused a NOT_FOUND_ERR DOM exception.

Fix: Use maColumnElement.getParentNode() instead of tableEle for insertBefore() and removeChild() operations, so it works correctly regardless of whether the column is a direct child of the table or nested inside header columns.

@its-awillerding Could you please verify the fix?
Thanks in advance, and thanks for your patience...
