Having problems passing more than one parameter with html:link tag
Hi, I am trying to pass 2 parameters with html:link. Since it is not legal to use the same attribute name more than once in the same tag, I created another reference 'tempId' to my 'submitQuotesForm' bean using bean:define tag but I am only getting the last param 'supplier_seq' added to my link. Here's my JSP code: bean:define id=tempId name=submitQuotesForm type=com.motorola.mms.msqc.beans.SubmitQuotesForm / html:link href=part.do paramId=motorola_part paramName=submitQuotesForm paramProperty=partNbr paramId=supplier_seq paramName=tempId paramProperty=supplierSeq bean:write name=submitQuotesForm property= partNbr / /html:link What am I doing wrong? -Nimmi

XML does not allow you to specify the same attributes twice in a single tag. If you want to add multiple parameters, use the following approach: * Create a Map (such as a HashMap or TreeMap) where the keys are the parameter names and the values are either String (for a single parameter value) or array of String (for multiple parameter value). * Use bean:define or some other technique to introduce this object into some appropriate scope. I tend to do this in my Actions (or business logic that they delegate to). * Code your link tag like this: bean:define id=parametersMap .../ html:link href=part.do name=parametersMap ... /html:link What am I doing wrong? -Nimmi Craig
Re: Having problems passing more than one parameter with html:link tag
I think you would need to use a map here. http://jakarta.apache.org/struts/struts-html.html#link Normally, the hyperlink you specify with one of the attributes described in the previous paragraph will be left unchanged (other than URL rewriting if necessary). However, there are two ways you can append one or more dynamically defined query parameters to the hyperlink -- specify a single parameter with the paramId attribute (and its associated attributes to select the value), or specify the name (and optional property) attributes to select a java.util.Map bean that contains one or more parameter ids and corresponding values.

RE: Having problems passing more than one parameter with html:link tag
Craig, In my case the link is on a column of an editable indexed properties table. And the 2 parameters for each row would be specific to that row. So where/how would I get the parameters into a HashMap? The JSP code is like this: % int i=0; % logic:iterate id=rfq name=submitQuotesForm property=rfqListBean.rfqList tr td bean:write name=submitQuotesForm property= '%= rfqListBean.rfqList[ + i +].usingLocationCode %' / /td td html:link href=part.do paramId=motorola_part paramName=submitQuotesForm paramProperty='%= rfqListBean.rfqList[ + i +].motorolaPartNbr %' bean:write name=submitQuotesForm property= '%= rfqListBean.rfqList[ + i +].motorolaPartNbr %' / /html:link /td td html:text property='%= rfqListBean.rfqList[ + i +].PriceObjective %' size=5 / /td and so on.. tr /logic:iterate Thanks -Nimmi -Original Message- From: Craig R.

So where/how would I get the parameters into a HashMap? Well, you've got them already don't you? The keys are the two things you are trying to pass for paramId and the values are the corresponding things you are trying to look up with paramName and paramProperty. In your page, it looks like you're using runtime expressions to try to get the values dynamically. To do it in the page, you'd need to use scriptlets. However, I would tend to have created an appropriate HashMaps in the Action that forwarded to this page, so all I'd have to do is reference it -- perhaps even create an array of HashMaps (one per row) so that it corresponds to your data lookups.
