Problem in PageReference

Hi,

Can we use PageReference inside for loop,

 

i am trying to pass the id using for loop but it gives error  as Too many script statments 200001

This is my code

public pageReference downloaddata()
	{
	 Pagereference pp;
			
	 integer j = selectedAttachments.size();
	
	 for(Integer i=0; i<=j; j++)
	{
	  pp=new Pagereference('/servlet/servlet.FileDownload?file='+selectedAttachments[i].id);
	 pp.setRedirect(true);
	 //return pp;
	 }
	 return pp;
	}

 

<apex:commandbutton action="{!downloaddata}" value="Download" />

 

Here im trying to download the attachment files that is more than one file

 

please help me how to solve this issue

how i can achieve this

The issue is that your loop is larger than the documented execution limits.

 

Currently, salesforce only allows 200,000 executed code statements.

 

I recommend that you use some WHERE or LIMIT clauses in your SOQL statment to stay below the limit or otherwise consider a batch apex class.

Hi colemab,

 

thanks for your Replay

 

i have used where clause and i this list contains only four records

 

i have one question

can we use 'PageReference pp=new pageReference();

inside the for loop to display new multiple new window at one click,

 

and how can i solve above problem, here i want to download selected Attachments at one click

 

 

thanks

You might want to do a system.debug on your variable J because it looks like it is larger than 200,000.

 

As far as I know, you can't use page reference to open mutiple new windows at once.  I could be wrong but I think each browser window is only allowed to have one page reference displayed at a time.

 

I think you will need to use java script to call a web service on the salesforce plat form once for each of your files.
