Exporting to HTML goes into infinit loop.

2003-10-24 05:31

We have a report that has a subreport, wich in its turn has a subreport, and when we try to export it to HTML jasper goes into an infinit loop, printing a link to the spacer px over and over.

If we export it to pdf all is well. The pdf-file is valid and opens fine in acrobat. When we send the JasperPrint to the JasperViewer it also displays fine.

Anyone experience this behaviour before?

Any help would be much appreciated!

I forgot to mention that we use version 0.5.0.

I using 0.5.0 version and I also have a similar problem.

He seems really that the program enters in infinite loop, but after + - 25 minutes the html file is generated with huge size.

If I export to PDF format the file has 7kb and it's ok.

If I export to HTML the file has 4194296kb and crash the IExplorer if I try to open this.

I don't know if this is the problem, but this case is only happening in two reports with sub-reports and scriptlets.

Any ideas for solve it?

I did some debugging with the jasper source. I found the line that causes the infinit loop.

It's in JRHtmlExporter line 643.

x += grid[y][x].colSpan - 1;

 

The problem is that when exporting my report x == 1

and grid[y][x].colSpan == 0, and after the line above x == 0.

So, when the loop continues the for loop adds 1 to x and we end up in the same place again.

 

Any ideas, Theodor?

I will continue looking in to this on monday.

I solved my problem altering the options height and width in the tag subreport. With the options width="0" and height="0" the file pdf was generated but the html no. Putting in "width" the width of the report and in "height" the sum of the heights of the subreports the file html is also generated.
