Xrm.Utility.openEntityForm size limit

Hi Everyone

I am doing some javascript customize jobs by using openEntityForm(entityName,null,parameters) .

I need to copy some information from current form page to open a new create form page(fill in the fileds by the parameter passed from previous form).

[object:parameters] contained all the fileds' value I want to pass. I found when the field value contain just a little text(like filed1:abc),it works well.

But when  the field value contains a lot of text(may be 2000 letters more) to pass,the new create form page will be opend and will be stucked on Loading business logic.

I think the openEntityForm's parameter has some size limitation.

Is there any other person who has same problem and find the solution?

Best Regards,
